Diabetes is a serious medical condition where the body struggles to control the amount of sugar in the blood. After you eat, your body breaks down food into a type of sugar called glucose, which gives your cells energy. A healthy body produces a hormone called insulin that helps glucose move from the blood into cells. In someone with diabetes, either the body doesn't make enough insulin, or the cells don't respond to insulin properly. This causes sugar to build up in the blood instead of powering the body's cells.

There are two main types. Type 1 diabetes often starts in childhood and means the body stops making insulin altogether. People with Type 1 need to take insulin every day, often through injections or a small pump that delivers it throughout the day. Type 2 diabetes is more common in adults and happens when the body doesn't use insulin effectively. Many people with Type 2 can manage it through healthy eating, exercise, and sometimes medication.

Without proper treatment, diabetes can damage organs over time. That's why people with diabetes carefully monitor their blood sugar levels, watch what they eat, and follow their doctor's treatment plan. Scientists are working on better treatments, and people with diabetes can live full, active lives when they manage their condition well.
