[Dietetic-hygienic measures in the control of arterial hypertension in obese females].

Since the evidence to data suggest that some obese person respond well to non-pharmacological measures, the aim of this study was to examine the extent of body weight reduction necessary to reduce blood pressure to normal values. A group of 250 obese women with hypertension (blood pressure measurements over 160/95) and an overweight of at least 20 per cent excess of ideal weight was included in the study. The patients were advised to take well balanced low-calorie (about 1000 kcal/day) diet containing 66 g proteins, 140 g carbohydrates, 13 g fat and 0.5 g salt. They were advised to increase daily physical activities. Low-calorie diets were used to decrease body weight in groups of patients with changed of unchanged antihypertensive drug therapy, also. Decrease in body weight resulted in significant decrease in blood pressure; over two-thirds of complaint patients achieve normal blood pressure with a loss of only 5-10 per cent of their weight excess even if at this point they were still overweight. In the group receiving no drug therapy 78 per cent reached normal blood pressure, 76 per cent in the patients whose antihypertensive treatment had to be modified during the study and 63 per cent in the group receiving unchanged drug therapy. It was concluded that weight reduction program (diet and physical activity) can be a possible approach to treat hypertension without drugs and patients can attain normotension long before achieving the ideal weight.
