Diabetes

Professionally updated: January 12, 2026

Diabetes, often known as diabetes mellitus, is a chronic condition where the body either does not produce enough insulin, or cannot effectively use the insulin it produces. Insulin is a hormone that helps regulate the amount of sugar (glucose) in the blood. Without effective regulation, blood sugar levels can become too high, which can lead to a number of health problems.

Types of diabetes

There are primarily two main types of diabetes: type 1 and type 2. Type 1 diabetes occurs when the body does not produce insulin. This type is often diagnosed early in life. Type 2 diabetes occurs when the body does not produce enough insulin or the cells ignore insulin. This type is more common and is often associated with lifestyle factors such as obesity and inactivity.

Symptoms of diabetes

The most common symptoms of diabetes include increased thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, and sores that do not heal. If you experience these symptoms, it is important to consult a doctor for a diagnosis.

Diabetes treatment

Diabetes treatment focuses on keeping blood sugar levels within a target range. This can be achieved through a combination of medication, diet, exercise, and regular blood sugar monitoring. Insulin injections may be necessary for people with type 1 diabetes and some with type 2 diabetes.

Complications of diabetes

Untreated diabetes can lead to serious complications such as cardiovascular disease, stroke, kidney disease, vision loss and nerve damage. Regular doctor visits and monitoring are important to prevent these complications.

Diabetes prevention

Although you cannot always prevent diabetes, you can reduce the risk by following a healthy diet, exercising regularly, avoiding tobacco, limiting alcohol consumption, and maintaining a healthy weight. It is also important to monitor blood sugar levels, especially if diabetes runs in the family.
