In hypertensive emergency, there is evidence of direct damage to one or more organs. The most affected organs include the brain, kidney, heart and lungs, producing symptoms which may include confusion, drowsiness, chest pain and breathlessness. In hypertensive emergency, the blood pressure must be reduced more rapidly to stop ongoing organ damage, however, there is a lack of randomized controlled trial evidence for this approach.
At present, the American Diabetes Association does not recommend general screening of the population for type 1 diabetes, though screening of high risk individuals, such as those with a first degree relative (sibling or parent) with type 1 diabetes should be encouraged. Type 1 diabetes tends to occur in young, lean individuals, usually before 30 years of age; however, older patients do present with this form of diabetes on occasion. This subgroup is referred to as latent autoimmune diabetes in adults (LADA). LADA is a slow, progressive form of type 1 diabetes. Of all the people with diabetes, only approximately 10% have type 1 diabetes and the remaining 90% have type 2 diabetes.
Much of the disease burden of high blood pressure is experienced by people who are not labeled as hypertensive. Consequently, population strategies are required to reduce the consequences of high blood pressure and reduce the need for antihypertensive medications. Lifestyle changes are recommended to lower blood pressure, before starting medications. The 2004 British Hypertension Society guidelines proposed lifestyle changes consistent with those outlined by the US National High BP Education Program in 2002 for the primary prevention of hypertension:
The discussion of weight and weight loss has evolved dramatically over the past 10-15 years. In some ways this has been for the better, but in other ways for the worse. I am incredibly grateful that the discussion has moved beyond just the calories in, calories out model (because we all know at this point that that is crap!). This notion though, that calories are not the key point of the equation has spurred a $66.3 BILLION dollar diet industry. Whether this is diet pills, the gym, or other contraptions that promise to shake your last 10lbs off the general understanding is that people are being taken for a very expensive ride. At the same time though, more North American’s are in the over weight and obese category than ever. So what digs?
While the lipid abnormalities seen with metabolic syndrome (low HDL, high LDL, and high triglycerides) respond nicely to weight loss and exercise, drug therapy is often required. Treatment should be aimed primarily at reducing LDL levels according to specific recommendations. Once reduced LDL targets are reached, efforts at reducing triglyceride levels and raising HDL levels should be made. Successful drug treatment usually requires treatment with a statin, a fibrate drug, or a combination of a statin with either niacin or a fibrate.
Naturally, since the metabolic syndrome is a disorder of energy distribution and storage, fat accumulation explains for a significant proportion of cardiovascular risk. However, obesity without metabolic syndrome does not confer a significant cardiovascular risk, whereas metabolic syndrome without obesity is associated with a significant risk of diabetes and cardiovascular disease. This association of metabolic syndrome with diabetes can be illustrated by generalized lipodystrophy (near complete absence of adipose tissue). The animals and humans with generalized lipodystrophy develop signs of metabolic syndrome in the absence of adipose tissue; and the metabolic syndrome progresses to type 2 diabetes. Adipose tissue transplantation in transgenic mice with lipodystrophy can cure the type 2 diabetes.
