DIABETES mellitus refers to a group of diseases that affect how your body uses blood glucose, commonly called blood sugar.
Glucose is vital to your health because it’s an important source of energy for the cells that make up your muscles and tissues. It’s also your brain’s main source of fuel. If you have diabetes, no matter what type, it means you have too much sugar in your blood, although the reasons may differ.
Too much sugar can lead to serious health problems.
Chronic diabetes conditions include type 1 diabetes and type 2 diabetes. Potentially reversible diabetes conditions include prediabetes – when your blood sugar levels are higher than normal, but not high enough to be classified as diabetes – and gestational diabetes, which occurs during pregnancy but may resolve after the baby is delivered.
Early symptoms of diabetes, especially type 2 diabetes, can be subtle or seemingly harmless.
You might not even have symptoms at all. Over time, however, you may develop diabetes complications, even if you haven’t had diabetes symptoms. Understanding possible diabetes symptoms can lead to early diagnosis and treatment – and a lifetime of better health.
If you’re experiencing any of the following diabetes signs and symptoms, see your doctor.
Excessive thirst and increased urination: Excessive thirst and increased urination are classic diabetes symptoms. When you have diabetes, excess sugar (glucose) builds up in your blood. Your kidneys are forced to work overtime to filter and absorb the excess sugar. If your kidneys can’t keep up, the excess sugar is excreted into your urine along with fluids drawn from your tissues. This triggers more frequent urination, which may leave you dehydrated. As you drink more fluids to quench your thirst, you’ll urinate even more
Fatigue: you may feel persistently tired. Many factors can contribute to this. They include dehydration from increased urination and your body’s inability to function properly, since it’s less able to use sugar for energy needs.
Weight loss: Weight fluctuations also fall under the umbrella of possible diabetes signs and symptoms. When you lose sugar through frequent urination, you also lose calories.
At the same time, diabetes may keep the sugar from your food from reaching your cells — leading to constant hunger. The combined effect is potentially rapid weight loss, especially if you have type 1 diabetes.
Blurred vision: Diabetes symptoms sometimes involve your vision. High levels of blood sugar pull fluid from your tissues, including the lenses of your eyes. This affects your ability to focus.
Left untreated, diabetes can cause new blood vessels to form in your retina — the back part of your eye — and damage established vessels.
For most people, these early changes do not cause vision problems.
However, if these changes progress undetected, they can lead to vision loss and blindness. — Online.
