Diabetes is a chronic disease that occurs because the body is unable to use blood sugar (glucose) properly. The exact cause of this malfunction is unknown, but genetic and environmental factors play a part. Risk factors for diabetes include obesity and high levels of cholesterol. Some specific causes are discussed below.
Lack of insulin production
This is primarily the cause of type 1 diabetes. It occurs when insulin-producing cells are damaged or destroyed and stop producing insulin. Insulin is needed to move blood sugar into cells throughout the body. The resulting insulin deficiency leaves too much sugar in the blood and not enough in the cells for energy.
This is specific to type 2 diabetes. It occurs when insulin is produced normally in the pancreas, but the body is still unable move glucose into the cells for fuel. At first, the pancreas will create more insulin to overcome the body’s resistance. Eventually the cells “wear out.” At that point the body slows insulin production, leaving too much glucose in the blood. This is known as prediabetes. A person with prediabetes has a blood sugar level higher than normal but not high enough for a diagnosis of diabetes. Unless tested, the person may not be aware, as there are no clear symptoms. Type 2 diabetes occurs as insulin production continues to decrease and resistance increases.
Genetics plays a role in determining how likely you are to develop some type of diabetes. Researchers don’t fully understand the role of genetics in the development of diabetes. According to the American Diabetes Association, statistics show that if you have a parent or sibling with diabetes, your odds of developing it yourself increase.
Although research is not conclusive, some ethnic groups seem to have a higher rate of diabetes. This is true for:
- Native Americans
- Pacific Islanders
- Hispanic Americans
Monogenic forms of diabetes result from single gene mutations. Monogenic forms of diabetes are rare, accounting for only 1 to 5 percent of all cases of diabetes found in young people.

According to the Mayo Clinic, your risk of developing type 2 diabetes increases as you age. Your risk goes up after age 45 in particular. However, the incidence of type 2 diabetes is increasing dramatically among children, adolescents, and younger adults. Likely factors include reduced exercise, decreased muscle mass, and weight gain as you age. Type 1 diabetes is usually diagnosed by the age of 30.

Poor nutrition may contribute to type 2 diabetes. A diet high in calories, fat, and cholesterol increases your body’s resistance to insulin.
Exercise makes muscle tissue respond better to insulin. This is why regular aerobic exercise and resistance training can lower your diabetes risk. Talk to your doctor about an exercise plan that is safe for you.
Although rare, certain hormonal conditions can also lead to diabetes. The following conditions can sometimes cause insulin resistance:
- Cushing’s syndrome: Cushing’s syndrome causes high levels of cortisol, which is the stress hormone in your blood. This raises blood glucose levels and may cause diabetes.
- Acromegaly: Acromegaly results when the body makes too much growth hormone. This can lead to excessive weight gain and diabetes if left untreated.
- Hyperthyroidism: Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone. Diabetes is one of the possible complications of this condition.
