Type 1 diabetes causes
Type 1 diabetes is caused by the immune system destroying the cells in the pancreas that make insulin. This causes diabetes by leaving the body without enough insulin to function normally. This is called an autoimmune reaction, or autoimmune cause, because the body is attacking itself. There is no specific diabetes causes, but the following triggers may be involved:
•Viral or bacterial infection
•Chemical toxins within food
•Unidentified component causing autoimmune reaction
Underlying genetic disposition may also be a type 1 diabetes cause.
Type 2 diabetes causes
Type 2 diabetes causes are usually multifactorial - more than one diabetes cause is involved. Often, the most overwhelming factor is a family history of type 2 diabetes. This is the most likely type 2 diabetes cause.
There are a variety of risk factors for type 2 diabetes, any or all of which increase the chances of developing the condition. These include:
•Living a sedentary lifestyle
•Pancreatitis or pancreatectomy as a cause of diabetes. Pancreatitis is known to increase the risk of developing diabetes, as is a pancreatectomy.
•Polycystic Ovary Syndrome (PCOS). One of the root causes of PCOS is obesity-linked insulin resistance, which may also increase the risk of pre-diabetes and type 2 diabetes.
•Cushing’s syndrome. This syndrome increases production of the cortisol hormone, which serves to increased blood glucose levels. An over-abundance of cortisol can cause diabetes.
•Glucagonoma. Patients with glucagonoma may experience diabetes because of a lack of equilibrium between levels of insulin production and glucagon production.
•Steroid induced diabetes (steroid diabetes) is a rare form of diabetes that occurs due to prolonged use of glucocorticoid therapy.
Effects of diabetes
When undiagnosed or uncontrolled, the effects of diabetes on the body can be noticed by the classic symptoms of diabetes, namely:
•Frequent need to urinate
•Blurred vision and
•Tingling or pain in the hands, feet and/or legs.
The kidneys are another organ that is at particular risk of damage as a result of diabetes and the risk is again increased by poorly controlled diabetes, high blood pressure and cholesterol. Diabetic nephropathy is the term for kidney disease as a result of diabetes. Damage to the kidneys takes place over a period of years and can picked up by nephropathy screening before it gets too serious. Treatment includes lifestyle changes and may include medicine to treat high blood pressure and cholesterol.
