Diabetes is a chronic disease characterized by high levels of sugar (glucose) in the blood. This occurs when the body either doesn't produce enough insulin (a hormone that regulates blood sugar levels) or doesn't use it effectively.
There are three main types of diabetes:
Type 1 diabetes: This occurs when the body's immune system attacks and destroys the cells in the pancreas that produce insulin. People with type 1 diabetes require insulin injections or an insulin pump to survive.
Type 2 diabetes: This occurs when the body becomes resistant to insulin, or when the pancreas doesn't produce enough insulin. Type 2 diabetes can often be managed with lifestyle changes such as diet and exercise, but some people with type 2 diabetes also require medication.
Gestational diabetes: This type of diabetes occurs during pregnancy and usually goes away after the baby is born. However, women who have had gestational diabetes are at increased risk of developing type 2 diabetes later in life.
Common symptoms of diabetes include increased thirst and urination, hunger, fatigue, blurry vision, and slow healing of cuts and bruises. If you suspect that you have diabetes, it's important to see a doctor for diagnosis and treatment. Diabetes can lead to serious complications if left untreated, including nerve damage, kidney damage, and heart disease.
