Some research
indicates that obesity is the one common element
linking insulin, diabetes type 2, and high blood pressure.
Obesity is common in both type 2 diabetes and
hypertension. Oddly, however, studies have found a
stronger association between hypertension and insulin
resistance in thin patients as well as
overweight people with type 2 diabetes. Some research
indicates that insulin resistance may cause sodium
retention, a contributor to high blood pressure. Obesity. Obesity on its own has a number of
possible effects that could lead to hypertension. It may
blunt certain actions of insulin that open blood vessels,
and it may cause structural changes in the kidney and
abnormal handling of sodium. It is also associated with
alterations in the systems that regulate blood flow.

Obesity. About one-third of patients with
high blood pressure are overweight.
Even moderately obese adults have double the risk of
hypertension than people with normal weights. In fact, the
increase in blood pressure in aging Americans may be due
primarily to weight gain. (In other cultures old age does not
necessarily coincide with weight gain or high blood pressure.)
Children and adolescents who are obese are at greater risk for
high blood pressure when they reach adulthood.

Weight Loss
An estimated 97 million adults in the US are overweight or
obese. Weight gain seems to be a primary determinant in blood pressure
increase, and weight loss may be even more important than salt restriction
in controlling blood pressure. Losing weight, particularly in the
abdominal area, immediately reduces blood pressure and helps reduce heart
size. Weight loss, particularly accompanied by salt restriction, may allow
patients with mild hypertension, even older people, to safely reduce or go
off medications. The benefits of weight loss on blood pressure appear to
be durable.
Thinness.
Interestingly, thin people with hypertension are at higher risk for heart
attacks and stroke than obese people with high blood pressure. Experts
surmise that thin people with hypertension are likely to have conditions
such as an enlarged heart or stiff arteries that cause the high blood
pressure and also pose greater dangers to health.
Overweight People and salt.
Overweight individuals may absorb and retain sodium differently from
people with normal weights. In fact, one 1999 study reported that high
sodium intake was associated with an increased risk of heart disease and
all-cause mortality in overweight, but not in normal weight, people.
Unfortunately, because overweight people generally consume more calories,
they are also likely take in more sodium.
WHAT ARE THE SYMPTOMS OF HIGH BLOOD PRESSURE?
No Symptoms
Hypertension has aptly been called the "silent killer"
because it usually produces no symptoms. Untreated hypertension increases
slowly over the years. It is important, therefore, for anyone with risk
factors to have their blood pressure checked regularly and to make
appropriate lifestyle changes. Such recommendations are urged for
individuals who have overall high-normal blood pressure, mild or above
systolic with normal diastolic pressure, family histories of hypertension,
or who are overweight or over age 40.
