    Could You Have Diabetes?

    For some people, the symptoms of diabetes are obvious. Unrelenting thirst, frequent urination, and always feeling tired are surefire tip-offs that something is amiss. But not all symptoms are this clear. In fact, many people may have no symptoms at all until a blood test tells them they have diabetes. This matters because the earlier you catch diabetes, the sooner you can take control of it and prevent complications. Here are 10 symptoms that suggest you could have diabetes.

    Diabetes Symptom #1: You feel fine

    For many people, diabetes causes no symptoms at all, especially early on. In fact, experts estimate that about 7 million people in the U.S. have undiagnosed diabetes. Early signs and symptoms can be vague, causing you to dismiss them or confuse them with other problems. Some people simply don't have noticeably high blood sugar, says Gregg F. Gerety, MD, an endocrinologist in Albany, N.Y. "Others get used to feeling poorly," he adds. Even subtle changes in the way you feel can be a good reason to see your doctor. Often, people don't realize how bad diabetes has been making them feel until after they get help.

  • Diabetes Symptom #2: Thirst and frequent urination

    Diabetes Symptom #2: Thirst and frequent urination

    People with diabetes may urinate as much as 20 times a day, with a full bladder every time, says Melvin Stjernholm, MD, an endocrinologist in Boulder, Colo. When you have extra glucose in your blood, due to diabetes, your kidneys work overtime to get rid of it. As this happens, the extra glucose soaks up water everywhere in your body, causing you to urinate more often. Frequent urination causes your body to become dehydrated -- and you end up feeling very thirsty.

  • Diabetes Symptom #3: You're tired all the time

    Diabetes Symptom #3: You're tired all the time

    Everyone experiences fatigue at one time or another. The combination of having too much to do and not enough sleep is a common problem. But if you have diabetes, your cells are also starved for glucose (sugar) -- your body's main source of energy. When glucose stays in your bloodstream rather than being used by your cells, you can end up feeling very tired. And if you're making nightly trips to the bathroom, you'll be even more exhausted.

  • Diabetes Symptom #4: Frequent yeast infections

    Diabetes Symptom #4: Frequent yeast infections

    Bacteria thrive in an environment with lots of sugar. That's why people with diabetes are often prone to yeast infections, says Betul Hatipoglu, MD, an endocrinologist at Cleveland Clinic. Common infection sites include the mouth (called "oral thrush") and places where you sweat, like the armpits, the skin between your toes, and under the breasts. Women with diabetes may also have more frequent vaginal and urinary tract infections. Itchy skin, a rash, white patches in your mouth, and vaginal itching, pain, and discharge are some of the most common signs of a yeast infection.

  • Diabetes Symptom #5: Cuts and bruises heal slowly

    Diabetes Symptom #5: Cuts and bruises heal slowly

    When you have an injury or infection, your body sends white blood cells to heal the damaged tissue. But too much glucose in your blood can slow the work of white blood cells, resulting in cuts and bruises that never seem to heal. "Even minor injuries like a cut with a razor will take longer to heal and may become infected," Hatipoglu says. "When your blood sugar goes up above 200, your white blood cells can't fight really well. And that weakens your immune system."

  • Diabetes Symptom #6: Frequent colds and flu

    The same weakened immune system that makes your cuts and bruises heal slowly can also make you more vulnerable to the viruses that cause colds and flu. "It's like a traffic jam where white blood cells can't get to the site of an infection or illness," Hatipoglu says. The result if you have diabetes? You may find yourself recovering from one cold -- just to catch another.

  • Diabetes Symptom #7: Your vision is blurred

    Diabetes Symptom #7: Your vision is blurred

    If you notice that things are looking fuzzy, consider getting checked for diabetes. Excess glucose in the bloodstream travels to the eyes and produces a sugar called sorbitol that obstructs your vision. It's as if you're looking through a glass that isn't clear, says Hatipoglu. "I've had patients who get new glasses, only to find out later their problem is from diabetes. Once I treat the diabetes, the blurred vision gets better."

  • Diabetes Symptom #8: Unexplained weight loss

    Diabetes Symptom #8: Unexplained weight loss

    You might be thrilled to notice you've dropped a few pounds -- and without even trying. But in people who have diabetes, sudden or unexplained weight loss may be a sign of the disease. When body cells aren't getting the energy they need from food, the body starts to break down muscle and fat for energy, says Stjernholm. "Breaking down fat for energy can produce ketones, which are toxic." If you don't know why you're losing weight, schedule a visit with your doctor.

  • Diabetes Symptom #9: You're always hungry

    Diabetes Symptom #9: You're always hungry

    If you aren't exercising more or eating less, but notice you're hungry a lot, it could be a sign of diabetes. Diabetes stops glucose from entering your cells, so your body can't convert the food you eat into energy. This, in turn, starves your cells. No matter how much you eat, nothing seems to satisfy your hunger. To make matters worse, all that extra food can also cause you to gain weight.

  • Diabetes Symptom #10: Numbness, tingling, or pain

    Diabetes Symptom #10: Numbness, tingling, or pain

    Numbness, tingling, or pain in your feet or hands may be a sign of peripheral neuropathy, a condition caused by damage to your nerves. No one knows exactly why diabetes causes neuropathy, or whether it's the result of too much glucose, excess insulin, or another metabolic changes, says Todd Levine, MD, co-director of the Banner Samaritan Neuropathy Clinic in Phoenix. "In many cases the development of neuropathy may be the first sign that you have a problem."
