NIDDM--the devastating disease.
Of the various types of diabetes mellitus, non-insulin-dependent diabetes (NIDDM) is by far the most common and is increasing rapidly in many populations around the world. It is a heterogeneous disorder, characterized by a genetic predisposition and interaction between insulin resistance and decreased pancreatic beta-cell function. There is a strong association between the presence of obesity and low levels of physical exercise and the development of NIDDM. However, NIDDM may also develop in lean individuals and the incidence increases significantly with increasing age. A diagnosis of impaired glucose tolerance or gestational diabetes is a strong predictor for future development of NIDDM and should signal appropriate interventions to prevent or delay the progression to NIDDM. NIDDM is frequently associated with other conditions such as hypertension, hypertriglyceridemia and decreased high-density lipoprotein which are additional risk factors for atherosclerosis and cardiovascular disease. The 'insulin resistance syndrome', which includes obesity, NIDDM, hypertension, hyperinsulinemia and dyslipidemia is a major and increasing cause of morbidity and mortality in many populations. In addition, people with NIDDM and poor glycemic control may develop severe microvascular complications of diabetes, including retinopathy, nephropathy and neuropathy. Appropriate diet, weight control and increased physical activity will increase insulin sensitivity in insulin resistant patients and are effective treatments for patients with NIDDM or may prevent the development of NIDDM in susceptible individuals. If these measures are unsuccessful, then oral hypoglycemic agents or insulin therapy may be required.(ABSTRACT TRUNCATED AT 250 WORDS)
