Diabetes is a chronic medical condition that occurs when the body cannot properly produce or use insulin, a hormone that regulates blood sugar levels. There are two main types of diabetes: type 1 diabetes and type 2 diabetes. Type 1 diabetes occurs when the body's immune system attacks and destroys the cells in the pancreas that produce insulin. This type of diabetes is usually diagnosed in children and young adults and requires daily insulin injections or the use of an insulin pump to manage blood sugar levels. Type 2 diabetes occurs when the body becomes resistant to insulin or doesn't produce enough insulin to maintain normal blood sugar levels. This type of diabetes is often associated with lifestyle factors such as obesity, physical inactivity, and a diet high in sugar and processed foods. It can often be managed through lifestyle changes such as losing weight, exercising regularly, and adopting a healthy diet. In some cases, medication or insulin therapy may also be necessary.
