Overview of diabetes
Glucose is used for energy, so checking levels is very important.
Diabetes mellitus, or diabetes, refers to a group of metabolic diseases where the body does not adequately produce insulin or use insulin properly. Insulin plays a crucial role in delivering glucose, or sugar, into the cells. This glucose is then used for energy.
People with untreated or poorly managed diabetes have abnormally high levels of glucose in their blood. This can lead to organ damage and other complications.
Too much glucose in the blood is called hyperglycemia. Symptoms include fatigue, blurry vision, hunger, increased thirst, and frequent urination.
Type 2 diabetes
Type 2 diabetes is the most common form of diabetes, accounting for about 90 to 95 percent of all diagnosed cases. In type 2 diabetes, the body develops a resistance to insulin.
This means the body cannot use insulin to absorb blood sugar into the cells so that it can be used for energy. Some people with type 2 diabetes may stop producing enough insulin to keep blood sugar levels within normal ranges.
Type 2 diabetes usually affects people who are older. It emerges more slowly than type 1 diabetes. Type 2 diabetes may not have noticeable symptoms. A person may have type 2 diabetes without knowing it.
Treatment of type 2 diabetes involves diet, exercise, and sometimes medications. Lifestyle changes can also help to prevent type 2 diabetes.
Type 1 diabetes
Type 1 diabetes is a lifelong disease, thought to be an autoimmune disease that usually develops during childhood and adolescence. In type 1 diabetes, the immune system mistakes insulin-producing cells for harmful invaders and destroys them.
Eventually, a person with type 1 diabetes stops producing insulin entirely. This means that glucose cannot enter the cells. The glucose level in the blood will rise until insulin therapy is begun.
Can type 1 diabetes be prevented?
There is no known way to prevent type 1 diabetes. Research is underway to understand the disease better and find ways to stop the destruction of insulin-producing cells.
