Diabetes
Diabetes is a chronic condition that occurs when the body cannot properly regulate the level of sugar (glucose) in the blood. This usually happens when the body does not produce enough insulin or cannot effectively use the insulin it produces. Insulin is a hormone that helps the body use sugar from food for energy.
When blood sugar levels remain high for long periods, it can affect many parts of the body including the heart, blood vessels, nerves, kidneys and eyes.
Types of Diabetes
There are several types of diabetes, including:
- Type 1 diabetes – occurs when the body produces little or no insulin
- Type 2 diabetes – occurs when the body does not use insulin effectively
- Gestational diabetes – develops during pregnancy and usually resolves after delivery
Type 2 diabetes is the most common form.
Common Symptoms
Symptoms of diabetes may include:
- increased thirst
- frequent urination
- fatigue
- blurred vision
- unexplained weight changes
- slow healing of cuts or wounds
Possible Causes
Diabetes can develop due to a combination of genetic, lifestyle and environmental factors. Risk factors may include family history, excess body weight, lack of physical activity and certain medical conditions.
