What is Diabetes Type 2?

Type 2 Diabetes Mellitus

Quick Answer

It is a chronic condition that affects how your body processes sugar (glucose). In Type 2 diabetes, the body either resists the effects of insulin or doesn't produce enough insulin to maintain normal glucose levels.

Overview

Type 2 diabetes is a common disease that affects millions of people worldwide. It occurs when the body cannot effectively use insulin, a hormone that helps sugar enter cells for energy. Over time, this leads to high levels of sugar in the blood, which can cause serious health problems like heart disease and nerve damage. This condition often develops gradually, and many people may not realize they have it until they experience complications. Risk factors include being overweight, having a sedentary lifestyle, and a family history of diabetes. For example, someone who is overweight and does not exercise regularly may find that their body struggles to manage blood sugar levels, leading to a diagnosis of Type 2 diabetes. Understanding Type 2 diabetes is crucial because it can significantly impact a person's quality of life. Managing the condition often involves lifestyle changes, such as improving diet and increasing physical activity. Early diagnosis and treatment can help prevent severe complications and enable individuals to lead healthier lives.
