Blood Pressure
High Blood Pressure/Heart Disease
What are they?
Excess body weight keeps the heart from working properly. The result can be high
blood pressure (hypertension), which can cause strokes and heart and
kidney damage. Evidence shows that the age-related lifetime risk of hypertension
in men and women ages 45 to 54 will double as their average BMI increases from
25 to 35. While hypertension may occur regardless of someone’s age, gender,
or body mass, it tends to be more severe in the obese.
How are they affected by bariatric surgery?
Bariatric surgery reduces excess body weight over time, which takes away some
of the strain on the heart. Changes in diet and exercise after surgery can lead
to significant improvement of hypertension and othercardiovascular
problems. Studies have shown reductions in total cholesterol and LDL levels and
increased HDLlevels. Even a weight loss of 10 percent can lower blood pressure
significantly.
What success have patients found through bariatric surgery?
A recent meta-analysis showed hypertension was resolved or improved in 78.5 percent
of patients. A study of 500 patients showed 92 percent resolution of hypertension.

Bariatric Surgery Leads To Long-term Blood Pressure Changes In Extremely Obese PatientsScienceDaily (Mar. 21, 2006) — Severely obese patients may experience significant, long-term improvements in blood pressure as they lose substantial amounts of weight after gastric bypass surgery, thereby contributing to their overall health, according to a new University of Pittsburgh study, published in the March issue of the Archives of Surgery. Excess body weight is associated with a host of health complications including diabetes, certain cancers and joint stress, with nearly two-thirds of very obese patients suffering from high blood pressure — the primary risk factor for both stroke and heart disease.
Weight-loss surgery saves lives, studies find

Surgically induced weight loss produces as much as a 40% reduction
in deaths in the 10 years after the operation, two large studies
reported today.
Researchers already knew that bariatric surgery sharply reduced
diabetes, hypertension and high cholesterol, in addition to improving
appearance and quality of life. But the new studies, reported in the
New England Journal of Medicine, are the first to document a
long-suspected link between weight loss and survival.
