Since there are three different types of diabetes there are multiple different reasons as to what causes them. Here is an overview of what causes each type of diabetes.
- Type 1 Diabetes Causes – Genes and environmental factors such as viruses
- Type 2 Diabetes Causes – Overweight, obesity and lack of activity: extra weight sometimes causes insulin resistance and therefore is common in people with type 2 diabetes. The location of where a person’s fat is also makes a difference such as if you have extra belly fat it is often linked to insulin resistance, diabetes and heart disease. Often times diabetes tends to run in families and occurs more often in racial/ethic groups such as in African Americans, Alaska natives, Asian Americans, Hispanics/Latinos, Native Hawaiians and Pacific Islanders. Genes can also increase the chance of diabetes due to a person being more likely to being overweight or obese. type 2 diabetes often starts with a person’s inability to not use insulin well which is called insulin resistance. With this resistance your body needs more insulin to help transfer glucose into cells.
- Gestational Diabetes Causes – Pregnancy: due to the large amount of hormones caused by pregnancy, gestational diabetes can develop during pregnancy. Insulin Resistance sometimes occurs in pregnant women later on in their pregnancy in which they cannot produce enough insulin. Women who are overweight or obese may already be borderline insulin resistant causing them to ultimately develop gestational diabetes. Gaining too much weight during pregnancy may also be a factor. Genes and a family history of diabetes can also contribute to gestational diabetes.
Other Causes of Diabetes: genetic mutations, Cystic Fibrosis, Hemochromatosis, hormonal diseases such as Cushing’s syndrome, Acromegaly, and hyperthyroidism. Some medications such as niacin, certain diuretics and anti-seizure drugs.
