.Keep blood pressure at bay by maintaining a healthy weight
Italian researchers have found that as many as 50 percent of overweight men and women with high blood pressure may have hypertension as a result of being overweight, and not obese.
The researchers reported the study at the American Heart Associationâ€™s 61st Annual Fall Conference of the Council for High Blood Pressure Research. They found that about 50 per cent of overweight, hypertensive adults, between the age group of 29 and 65 years, achieved normal body weight and blood pressure after six months of treatment with a reduced-calorie diet.
â€œThis is important because it means that in these patients with elevated blood pressure who were overweight, the blood pressure was not a form of essential hypertension but was hypertension secondary to body weight,â€ Roberto Fogari, M.D., lead investigator of the study and professor of medicine at the University of Pavia, Italy, said.
â€œThese findings apply to western societies in general, but only to overweight patients, not to obese patients, with high blood pressure,â€ he added.
About one in three American adults have high blood pressure, which is defined as a systolic pressure of 140 mm Hg or higher or a diastolic pressure of 90 mm Hg or higher. High blood pressure increases the risk for heart disease and stroke.
The researchers therefore conducted a study in which they analysed 210 overweight men and women whose systolic blood pressure was more than 140 mmHg, but less than 159 mm Hg, and whose diastolic blood pressure was more than 90 mm Hg, but less than 99 mm Hg.
The study patients, who had never been treated for high blood pressure, were overweight with a body mass index (BMI) 25 to 29.9 kg/m2. An individualised reduced-calorie diet was designed for each patient and reflected their specific food preferences. â€œThe dietâ€™s main aim was to reduce calories to reduce the weight of each patient,â€ Fogari said.
About 50 per cent of the patients were also treated with a medication used with a low-calorie diet to help lose weight and maintain weight after losing pounds.
The medicine is in a class of drugs called lipase inhibitors. It works in the intestines, where it blocks some of the fat eaten from being absorbed and digested. This undigested fat is then removed in bowel movements. It is often used with a low-calorie diet to achieve weight loss and maintain weight after weight loss.
