Diabetes

 What Is Diabetes? - NIDDK

Diabetes is a chronic disease that occurs either when the pancreas does not produce enough insulin or when the body can't effectively use the insulin it produces. Insulin is an hormone that regulates blood glucose. Uncontrolled diabetes can cause raised blood glucose (hyperglycaemia) and over time it leads to serious damage to the body's systems.

Symptoms of diabetes can occur suddenly. In type 2 diabetes they can be mild and may take many years to be noticed. The symptoms may include: feeling very thirsty, needing to urinate more than usual, blurred vision, feeling tired, losing weight unintentionally. Over time, diabetes can damage blood vessels in the heart, eyes, kidneys and nerves.

TYPE 1 DIABETES

It's characterized by deficient insulin production and requires daily introduction of insulin.

TYPE 2 DIABETES

It affects to how your body uses glucose for energy. It stops the body for using glucose properly, which can lead to high levels of blood sugar if it's not treated. Type 2 diabetes is often preventable. Factors that contribute to developing type 2 diabetes are overweight, not enough exercise and genetics.

GESTATIONAL DIABETES

Gestational diabetes is hyperglycaemia with blood glucose values above normal but below those diagnostic of diabetes. Gestational diabetes occurs during pregnancy.
