Diabetes is a chronic health condition in which the body is unable to properly use and store glucose (a type of sugar). Glucose is an important source of energy for the body, but when it can't be used or stored properly, it can lead to high blood sugar levels and a range of health problems.

There are three main types of diabetes: type 1, type 2, and gestational diabetes.

Type 1 diabetes is an autoimmune disorder in which the body's immune system attacks and destroys the cells that produce insulin, a hormone that helps regulate blood sugar levels.
Type 2 diabetes is the most common form of diabetes, and it occurs when the body becomes resistant to insulin or doesn't produce enough of it.
Gestational diabetes is a temporary form of diabetes that occurs during pregnancy.

Diabetes is usually diagnosed through a blood test called a glucose tolerance test or a fasting plasma glucose test. These tests measure the level of glucose in the blood and can help determine whether an individual has diabetes.

There is currently no cure for diabetes, but it can be managed through lifestyle changes and medication. By following a healthy diet, exercising regularly, and taking medications as prescribed, individuals with diabetes can successfully manage their blood sugar levels and reduce their risk of complications.

If diabetes is not properly managed, it can lead to a range of complications, including heart disease, stroke, nerve damage, blindness, kidney disease, and amputations. It's important for individuals with diabetes to work with their healthcare team to carefully manage their blood sugar levels and prevent complications.
