Overview
The underlying cause of type 2 diabetes is insulin resistance. The exact cacuse of insulin resistance is not known, however several theories exist. Central obesity, aging, and high glycemic diets are most commonly implicated in the development of type 2 diabetes.
Causes
There are no accurate causes for type 2 diabetes because this disease is caused by multiple risk factors and the effect of environmental factors in a genetically susceptible person that resul in hyperglecemia and insulin resistance. Numerous theories as to the exact cause and mechanism in type 2 diabetes. Central obesity (fat concentrated around the waist in relation to abdominal organs, but not subcutaneous fat) is known to predispose individuals for insulin resistance. Abdominal fat is especially active hormonally, secreting a group of hormones called adipokines that may possibly impair glucose tolerance. Obesity is found in approximately 55% of patients diagnosed with type 2 diabetes.[1] Other factors include aging (about 20% of elderly patients in North America have diabetes) and family history (type 2 is much more common in those with close relatives who have had it). In the last decade, type 2 diabetes has increasingly begun to affect children and adolescents, likely in connection with the increased prevalence of childhood obesity seen in recent decades in some places.[2]
The following medications may cause type 2 diabetes:
- Desogestrel and Ethinyl Estradiol
- Dexamethasone
- Estropipate
- goserelin
- Indinavir
- interferon alfacon-1
- Pasireotide
- Pegylated interferon alfa-2b
- Pergolide
- Ritonavir
- Saquinavir mesylate
- Tipranavir
