Type 2 diabetes can lead to a range of serious complications, so it's important to understand what can happen and how to recognize the symptoms.

Right now, you might be experiencing some of the symptoms of type 2 diabetes, which include :

  • Frequent urination
  • Unusual thirst
  • Extreme hunger
  • Unusual weight loss
  • Extreme fatigue and irritability
  • Blurred vision
  • Cuts/bruises that are slow to heal
  • Tingling/numbness in the hands and feet
  • Skin, gum, or bladder infections

As you bring your blood-glucose levels under control, these symptoms will begin to abate. However, like many people with type 2 diabetes, you might not have any symptoms at all ? which can sometimes make it harder to grasp the seriousness of your diagnosis.

Whether you have symptoms or not, over time uncontrolled levels of high blood sugar can lead to tissue damage throughout your body, from your eyes to your toes. When you have diabetes, you will be seeing your physician on a regular basis to monitor your progress. And it will become more important than ever to get regular dental and eye exams. That's because diabetes can lead to a range of complications, which you need to know about and be on the lookout for because they are so serious. Fortunately, controlling your blood-glucose levels can help prevent many of these secondary problems.

Diabetic Complications

  • Gum disease and infections
  • Vision problems, including a risk of cataracts, glaucoma, and eye infections; a condition called diabetic retinopathy can lead to vision loss or blindness
  • Neuropathy, or nerve damage, that can cause pain or numbness in your hands and feet
  • Circulatory problems that can eventually lead to amputations (feet, legs)
  • Heart disease
  • Kidney problems
  • High blood pressure

Remember: Taking control of your blood-glucose levels can help prevent many of these secondary problems. Work closely with your care team to maintain a proper diabetes management plan and to watch carefully for troubling symptoms or signs of a developing problem.

Next step: Type 2 Diabetes: A Race for Cure

Although fruit contains sugar, it's also loaded with essential vitamins, minerals, and fiber. Learn how fruit can be part of a healthy type 2 diabetes diet.

Most people with type 2 diabetes know that they can't indulge in a daily chunk of chocolate cake for dessert or sip sugar-laden drinks. But is all sugar off limits in a type 2 diabetes diet, even the natural sugar found in fruits?

"In general, for most patients, all kinds of fruit are fine," says dietitian Nora Saul, MS, RD, a certified diabetes educator at the Joslin Diabetes Center in Boston. Fruit is a healthy snack, packed with the fiber, vitamins, and nutrients essential for good health.

But that doesn't mean that people with type 2 diabetes can eat all the fruit they want ? fruit will affect their blood sugar levels. "Every single fruit has carbohydrates," says Lorena Drago, a certified diabetes instructor and consumer adviser for the American Association of Diabetes Educators. Following a few simple guidelines will help you make the right choices.

Diabetes and Fruit: The Glycemic Index

If you have diabetes and fruit is on your preferred menu, you'll need to pay attention to its glycemic index ranking.

The glycemic index is a numerical rating assigned to carbohydrate foods and indicates how quickly a food will affect blood sugar levels. Low-glycemic-index foods raise blood sugar levels at a slower rate than higher glycemic index foods, says Saul. So low-glycemic-index foods will help you keep your blood sugar levels more stable ? the goal for everyone with diabetes.

Apples, oranges, and pears are some of the fruits with a low glycemic index and may be a good choice if you need to limit your carbohydrates on a particular day.

Diabetes and Fruit: Go for the Berries

If you're looking for the most nutritional bang for your carbohydrate buck, opt for berries, says Drago. Strawberries, blackberries, blueberries, and other berries are nutrition powerhouses in terms of nutrients.

But just because they're healthy, remember not to overdo it on the carbohydrates, as carbs will affect blood sugar levels. It's important to stay within your daily carbohydrate budget, which is specific to every individual with diabetes. When you're selecting your fruit, it's also good to go for variety.

"Different fruits provide different vitamins and minerals," says Saul. "You just have to watch the portions and not eat too much at once." If your favorite fruits have a very high glycemic index, eat them in smaller portions or include them in a meal that has an overall low glycemic index, she suggests.

A wide variety of fruits is the best choice for a type 2 diabetes diet, says Saul, but she suggests being sure to include fruits high in vitamin A and C and rich in fiber.

Diabetes and Fruit Juice

Drinking juice doesn't not provide the same nutritional benefits of the whole fruit, Saul says, so tread carefully around fruit juices.

"Most juices don't have any protein, any fiber, or any fat," Saul says. And because they're liquid, they leave the stomach very quickly. With "nothing to slow down absorption, they tend to spike blood sugar levels very quickly," she points out.

Saul explains that fruit juice isn't totally off limits, but moderation is key for any type 2 diabetes diet. If you do choose juice, "it should be small quantities, 4 ounces or less," she says. You'll get the same vitamins that you'd get from eating the whole fruit, but you will miss out on the more complete nutrition provided by whole fruit.

You don't have to skip nature's sweet treats when you have diabetes. You can, and should, enjoy fresh fruit as part of a healthy type 2 diabetes diet. Just remember that moderation rules when you're factoring in these carbs.

If you were recently diagnosed with type 2 diabetes, or even if you have had diabetes for a long time, you may be confused about how to eat to manage your blood glucose levels. It seems that everyone has an opinion, and many of these opinions contradict each other.

So what are you to believe? And what truly works at helping you maintain your glucose levels in a healthy range?

Let's take a look at some of the biggest diabetes diet myths, why they don't work, and what actually will.

Myth No. 1: If You Have Diabetes, You Must Avoid All Sugar

The Truth: Excess sugar good for anyone's diet, regardless of whether they have diabetes or not. However, just because you have diabetes, not all sugar and sweets are off limits. All carbohydrates, including simple sugars as well as complex carbohydrates, are broken down into glucose during digestion. This glucose is then used as energy in your cells. Because all forms of carbohydrates break down into glucose and therefore raise your glucose levels, you need to monitor your total carbohydrate intake, especially at one sitting, for optimal glucose management.

Although you must be careful not to overeat carbohydrates at one sitting, you can still indulge in a few sweet treats at times. Complex carbohydrates such as whole grains, whole fruits and vegetables, and low-fat milk are the best choices for everyone, due to their rich nutrient and fiber content. But you can enjoy a food containing simple sugars, such as a cookie, in moderation without spiking your glucose levels, as long as you keep the portion under control. Keep in mind, however, that when it comes to simple sugars, moderation is key for everyone, not just people with diabetes.

Myth No. 2: Any White Food Is Bad

The Truth: When you think of white foods, what comes to mind? White flour, white sugar, white bread? What about white potatoes, cauliflower, and onions? Are all of these white foods bad for glucose levels? Definitely not! Sure, some white foods are highly processed, such as enriched flour and sugar. But just because a food is white in appearance doesn't mean it will be rapidly converted into glucose in the body and therefore spike your levels. In fact, white vegetables such as cauliflower and onions are excellent for blood glucose control as they are very low in calories and high in fiber, and provide few carbohydrates.

White potatoes get a bad rap as well. It is true that sweet potatoes are digested more slowly and prompt a smaller elevation in glucose levels after eating, but that doesn't mean you need to avoid white potatoes if you have diabetes. In moderation, and as part of a balanced meal - with vegetables, lean proteins, and healthy fats - you can enjoy white potatoes as your starch and still maintain healthy glucose levels.

Myth No. 3: The Only Way to Lower Glucose Levels and Weight Is to Follow a Low- or No-Carb Diet

The Truth: If you are newly diagnosed with diabetes, you may feel as though everyone around you is telling you to steer clear of all sources of carbohydrates. Since carbohydrates are found in everything from fruit to bread to milk and even vegetables, you may feel as though there's nothing left to eat. But the good news is that you can still eat carbohydrates. Managing diabetes is about keeping your glucose levels in a healthy range. Too-high glucose levels can damage your body, but too-low levels can be dangerous as well. Eating carbohydrates as part of a well-balanced diet will help you keep your levels within a healthy range.

Instead of avoiding carbohydrates, focus instead on choosing the healthiest types. Select whole vegetables and fruits, whole-grain bread, and low-fat dairy for a diet rich in nutrients and fiber. Space your carbohydrate intake out throughout the day by balancing your plate with carbs, lean protein, and healthy fat at each meal. A balanced diet will not only help you achieve optimal glucose levels, it will also improve your overall health.

Myth No. 4: Sugar-Free Foods Won't Impact Blood-Sugar Levels

The Truth: Sugar-free foods do not necessarily equal carbohydrate-free foods. Many foods marketed as sugar-free have replaced sugar with sugar alcohols. Sugar alcohols provide fewer calories and make less of an impact on glucose levels than regular sugar, but they can still elevate glucose levels if you consume them in large amounts. In addition, bread-based sugar-free foods, such as sugar-free desserts, are typically rich in carbohydrates from sources such as flour and grains. It's essential to read labels carefully on sugar-free foods. Look at the total grams of carbohydrates and not just grams of sugar. If you focus only on the marketing claims, such as "sugar-free," you may struggle to lower your glucose levels without knowing why.

As you can see, there are many diet myths surrounding diabetes. But managing your glucose levels doesn't have to be complicated. A balanced diet rich in whole foods and limited in processed foods and simple sugars - the same diet that we should all follow, regardless of whether we have diabetes or not! - can help you keep your glucose levels in a healthy range.

Many people associate heart disease with obvious symptoms like chest pain. But there are some not-so-obvious connections, like swollen feet or bleeding gums, that should also merit a heart check from your doctor.

Heart disease symptoms in women or in men are indications that you feel or experience, while a sign of heart disease is something your doctor can see or find. Obvious heart disease symptoms include shortness of breath or chest pain. But your doctor may also look for some surprising heart disease signs during an examination.

Knowing the signs of heart disease is important because you may have them before you have any of the common heart disease symptoms. Letting your doctor know about these warning signs could help you get an early jump on heart disease.

Are you doing everything you can to manage your heart condition? Find out with our interactive checkup.

"Signs like ankle swelling or weight gain do not necessarily mean you have heart disease, but taken together with other symptoms of heart disease, laboratory studies, and family history, they are an important part of making a diagnosis of heart disease or heart failure," says Carl E. Orringer, MD, director of preventive cardiovascular medicine at the University Hospitals Case Medical Center in Cleveland.

Swelling of the Feet and Lower Legs

Retention of fluid in the feet and legs is known as peripheral edema. Edema may appear as "sock marks" at the end of the day. Mild peripheral edema is common. Your doctor may check for this sign by pressing a finger against your ankle or shin bone to see if a depression is left behind. This is called "pitting edema."

Edema may be a sign of heart failure because, when your heart is not pumping well, fluid from inside your blood vessels tends to leak out into surrounding tissues. The legs and ankles are common areas for edema because of the effects of gravity.

"Peripheral edema may be caused by a host of issues," says Dr. Orringer. "The bottom line is that most people with peripheral edema do not have heart disease, but it could be an important sign if there are other signs and symptoms of heart failure."

Male Pattern Baldness

"If you watched any of the royal wedding, you might have noticed that Prince William is balding on the top of his head. This type of balding of the crown of the head in young men may be a sign of an increased risk for heart disease," says Orringer.

Several large studies have confirmed the link between baldness and heart disease. Compared to men with a full head of hair, men with crown loss have an increased risk of heart disease of about 23 percent. Men with complete loss of hair on the top of their head have an increased risk of 36 percent.

The combination of hair loss, high blood pressure, and high cholesterol pushes the risk even higher. This link may be due to too much of the male hormone testosterone, which interferes with hair growth on the head and causes hardening of the arteries. That doesn't mean you are doomed to heart failure if you are bald, but it does suggest you should be screened more carefully for other signs and symptoms of heart disease.

Yellow Bumps on the Skin

Xanthomas are deposits of fat that build up under the skin. They may appear as small yellow bumps or as flat, wide plaques on your elbows, knees, hands, feet, or buttocks. A type of xanthoma called "xanthelasma palpebra" appears on the eyelids. These yellow, fat deposits can potentially be signs of heart disease because they may indicate high levels of fats in the blood.

"Xanthomas may be a sign of a rare, inherited type of blood disorder in which high levels of triglycerides accumulate in the blood. Xanthomas may also be a sign of increased cholesterol and they may disappear once cholesterol levels are under control," says Orringer.

Gum Disease

Swollen, sore, or bleeding gums are usually a sign of poor oral hygiene, but may also be an important sign of heart disease. "The association between gum disease and heart disease is the real deal," says Orringer. "There is plenty of research available now that backs up this connection."

Gum disease and heart disease may be linked because they are both signs of poor circulation, or there could be common bacteria that are involved in both gum disease and plaque build-up inside coronary arteries. The link may also have something to do with the body's response to prolonged inflammation. In any case, taking better care of your teeth and gums is a good way to cut down your risk for heart disease.

Signs of Heart Failure

Heart failure means the heart is not functioning as well as it should. It doesn't mean the heart has failed. Another term for heart failure is congestive heart failure, or CHF. Heart failure gradually gets worse over time. Some early warning signs may include :

  • Weight gain. If your heart starts to fail and fluid starts to build up in your tissue, causing edema, you might see a sudden weight gain.
  • Frequent urination. Heart failure may cause decreased blood flow to the kidneys, which causes you to retain more fluid. One of the signs of this fluid may be frequent urination.
  • Cataracts. Although the exact connection is not known, studies show that people who have cataracts are at higher risk for heart disease, high blood pressure, and high cholesterol. "This link is probably more of an association than a sign of heart disease," says Orringer.
  • Nighttime cough. "One of the signs of heart failure may be the build-up of fluid in the chest and heart when lying flat at night. This pressure can cause a nighttime cough," explains Orringer.

Remember that all these heart disease signs may have many different causes. They do not mean you have or will get heart disease. But combined with other heart disease signs and symptoms, your blood tests, and your family history, they give your doctor the best chance to find heart disease early and keep you in good health.

Once you've been diagnosed with type 2 diabetes, open communication with a doctor you trust will be key to managing your health. Now that you know what it means to have type 2 diabetes, you're ready to have a dialogue with your doctor about how you'll manage this disease ? together. Here are 15 questions to get the conversation started.
  1. Do you have special training in diabetes? If not, can you refer me to a specialist?
  2. How many patients with type 2 diabetes do you see?
  3. What tests will you do at regular office visits? How often do I have to have the tests, and what will they tell you?
  4. Is there anything I need to do in advance of the tests? For example, do I need to fast if I'm going to have a blood-sugar test?
  5. Can you refer me to a diabetes educator or a registered dietitian?
  6. I have a family history of heart attack and/or stroke. Will my diabetes put me at greater risk for those problems?
  7. How can I tell if my blood sugar is too high or too low? What should I do about either high or low blood sugar?
  8. Will I have to test my own blood sugar at home every day?
  9. What are the best treatments for type 2 diabetes?
  10. Will I need to take pills or inject insulin? Will I ever be able to stop using them once I start?
  11. What are the risks of not treating type 2 diabetes?
  12. How will type 2 diabetes affect me over the long term?
  13. What should I do if my symptoms worsen or if I experience new symptoms?
  14. Is it possible for type 2 diabetes to go away on its own?
  15. Are my kids at greater risk for developing type 2 diabetes since I have it?

Hyperglycemia is the technical term for when blood-glucose levels (or blood-sugar levels) are too high because the body isn't properly using or doesn't make the hormone insulin. The symptoms of hyperglycemia develop slowly, over a period of hours or even days. Hyperglycemia doesn't even cause symptoms until glucose levels are significantly high  ? above 200 milligrams per deciliter (mg/dL), or 11 millimoles per liter (mmol/L). The longer blood-glucose levels stay high, the more serious the symptoms become.

Symptoms of hyperglycemia include :
  • Blood glucose over 200 mg/dL
  • More urine output than usual
  • Increased thirst
  • Dry skin and mouth
  • Decreased appetite, nausea, or vomiting
  • Fatigue, drowsiness, or lethargy

If hyperglycemia goes untreated, it can cause:

  • Fruity-smelling breath
  • Nausea and vomiting
  • Abdominal pain
  • Shortness of breath
  • Dry mouth
  • Weakness
  • Confusion
  • Buildup of toxic acids (called ketones) in your blood and urine
  • Coma

The dangerously high blood-glucose levels of hyperglycemia can result from:

  • Not taking enough insulin
  • An illness such as a cold or the flu
  • An infection
  • Eating too much
  • Excessive stress
  • Taking certain medications

To avoid episodes of hyperglycemia, take your usual insulin exactly as prescribed by your doctor (do not skip a dose!) and eat regular, balanced meals.

Next Step: How to Treat Low Blood Sugar

Over time, the presence of too much glucose in your cells can injure the walls of the tiny blood vessels called capillaries that deliver blood to your nerves, especially in the legs. This can cause tingling, numbness, burning, or pain.

Poorly controlled blood glucose can even cause you to lose all sense of feeling in the affected limbs - and a loss of feeling in your feet makes you more vulnerable to injury and infection. Let's say you get a blister or small cut on your foot that you don't feel: Because you don't know it's there, you may miss the symptoms of an infection in the wound. It's imperative for you to check your feet regularly to avoid this and be meticulous in your foot care, because untreated infections can result in gangrene (the death of tissue) and may lead to the amputation of the affected limb or toes.

Diabetes can also make it more difficult for your body to fight infections in general. Various skin conditions are linked to diabetes, and even the most minor cuts or sores can turn serious fast. Any bumps, cuts, or scrapes should be cleaned and treated with an antibiotic cream and monitored carefully.

Nerve Damage: What to Watch For

If you notice any of these symptoms associated with nerve damage or infection, see your doctor:

  • Inflammation and tenderness anywhere on your body
  • Red, itchy rash surrounded by small blisters or scales
  • Cuts, sores, or blisters on your feet that are slow to heal and are not as painful as you would expect (due to a loss of sensation)
  • Numbness, tingling, or burning sensations in your hands or feet, including your fingers and toes
  • Sharp pain that gets worse at night
  • Muscle weakness that makes walking difficult
  • Bladder infections and problems with bladder control
  • Bloating, stomach pain, constipation, nausea, vomiting, or diarrhea
  • Erectile dysfunction in men and vaginal dryness in women

Remember: If you keep your blood-glucose levels on target, you can help prevent or delay nerve damage. If you already have nerve damage, this will help prevent or delay further damage. You should also speak to your doctor about other treatments that can help.

Next step: Protecting Your Kidneys

Early-stage colon cancer generally begins as a polyp, a growth that protrudes from the colon wall. Some polyps can turn into cancer, but regular screenings can help detect these polyps so they can be removed before they become cancerous. That's why regular screening for people over 50 and those at high risk of developing colon cancer is so important.

There are five main types of colon cancer screenings, including:
  • Fecal occult blood test. A series of stool samples are taken and examined for hidden blood, since some polyps and cancers bleed. If blood is found in the stool sample, your doctor may order a colonoscopy for further evaluation.
  • Double contrast barium enema. Liquid containing a contrast dye (to help it show up on an X-ray) is introduced into the colon through the rectum, and the area is X-rayed to check for polyps or abnormal lesions. If a polyp is found on the X-ray, a colonoscopy will be done as a follow-up test.
Learn about three other screening tests for colon cancer.

Uncontrolled diabetes can be life-threatening. Help prevent these serious diabetes complications by learning the warning signs.

People with type 2 diabetes are at increased risk of many serious health problems, including heart attack, stroke, vision loss, and amputation. But by keeping your diabetes in check ? that means maintaining good blood sugar control ? and knowing how to recognize a problem and what to do about it should one occur, you can prevent many of these serious complications of diabetes.

Heart Attack

Heart disease and stroke are the top causes of death and disability in people with diabetes. Heart attack symptoms may appear suddenly or be subtle, with only mild pain and discomfort. If you experience any of the following heart attack warning signs, call 911 immediately:

  • Chest discomfort that feels like pressure, squeezing, fullness, or pain in the center of your chest, lasting for a short time or going away and returning
  • Pain elsewhere, including the back, jaw, stomach, or neck; or pain in one or both arms
  • Shortness of breath
  • Nausea or lightheadedness

Stroke

If you suddenly experience any of the following stroke symptoms, call 911 immediately. As with a heart attack, immediate treatment can be the difference between life and death. Stroke warning signs may include :

  • Sudden numbness or weakness in the face, arm, or leg, especially if it occurs on one side of the body
  • Feeling confused
  • Difficulty walking and talking and lacking coordination
  • Developing a severe headache for no apparent reason

Nerve Damage

People with diabetes are at increased risk of nerve damage, or diabetic neuropathy, due to uncontrolled high blood sugar. Nerve damage associated with type 2 diabetes can cause a loss of feeling in your feet, which makes you more vulnerable to injury and infection. You may get a blister or cut on your foot that you don't feel and, unless you check your feet regularly, an infection can develop. Untreated infections can result in gangrene (death of tissue) and ultimately amputation of the affected limb. A recent large study from Sweden of 2,480 patients with diabetic foot ulcers found that certain factors increased the likelihood of amputation, including being male and having had diabetes for longer than 23 years.

Diabetes can also make it more difficult for your body to fight infections, causing skin problems. Various skin conditions are linked to diabetes, and even the most minor cuts or sores can turn serious fast. Any bumps, cuts, or scrapes should be cleaned and treated with an antibiotic cream and monitored carefully.

If you notice any of the following symptoms, see your doctor:

  • Inflammation and tenderness anywhere on your body
  • Red, itchy rash surrounded by small blisters or scales
  • Cuts, sores, or blisters on your feet that are slow to heal and are not as painful as you would expect
  • Numbness, tingling, or burning sensations in your hands or feet, including your fingers and toes
  • Sharp pain that gets worse at night
  • Muscle weakness that makes walking difficult
  • Bladder infections and problems with bladder control
  • Bloating, stomach pain, constipation, nausea, vomiting, or diarrhea
  • Erectile dysfunction in men and vaginal dryness in women

Kidney Disease

Type 2 diabetes increases your risk of kidney disease, or diabetic nephropathy, a condition in which the blood vessels in your kidneys are damaged to the point that they cannot filter out waste properly. If left untreated, dialysis (a treatment to filter out waste products from the blood) and ultimately a kidney transplant may be needed.

Typically, you won't notice symptoms of kidney disease until it has advanced. However, if you experience any of the following symptoms, tell your doctor:

  • Swelling in your ankles and legs
  • Leg cramps
  • A need to go to the bathroom more often at night
  • A reduction in your need for insulin
  • Nausea and vomiting
  • Weakness and paleness
  • Itching

The best way to prevent type 2 diabetes-related kidney problems is to have your urine, blood, and blood pressure monitored regularly and to keep your blood sugar and blood pressure under control.

Eye Problems

People with type 2 diabetes are at risk of several eye conditions, including diabetic retinopathy (which affects the blood vessels in the eye), glaucoma, and cataracts. If left untreated, these conditions can cause vision loss.

Call your doctor if you notice any of these warning signs:

  • Blurry vision that lasts for more than two days
  • Sudden loss of vision in one or both eyes
  • Floaters, black or gray spots, cobwebs, or strings that move when you move your eyes
  • A sensation of seeing "flashing lights"
  • Pain or pressure in one or both eyes

Hyperglycemia

Hyperglycemia means you have too much sugar in your blood. High blood sugar doesn't always produce symptoms; therefore, it is important to check your blood sugar regularly, as indicated by your doctor. When symptoms of hyperglycemia occur, they may include :

  • Frequent urination
  • Extreme thirst
  • Feeling tired and weak
  • Blurry vision
  • Feeling hungry even after eating

If you frequently have high blood sugar, tell your doctor. He or she may need to make changes to your medication and suggest diet and lifestyle modifications to help you gain and maintain better blood sugar control.

The key to preventing many of the complications of diabetes is to keep your blood sugar at a healthy level. To do this, eat right, exercise, monitor your blood sugar as recommended by your doctor, and don't smoke.

Report any unusual signs or symptoms to your doctor. Together you can work to prevent these diabetes-related health complications.
