Can weight loss lower blood pressure

Losing weight can lower blood pressure, and controlling weight can help improve hypertension. When overweight or obese, an increase in adipose tissue in the body can lead to an increase in peripheral vascular resistance and an increase in cardiac load. After weight loss, peripheral vascular resistance decreases, cardiac output decreases, and blood pressure decreases accordingly. Clinical studies have found that for every 5 kilograms of weight loss, systolic blood pressure can decrease by 5-20 millimeters of mercury. Weight loss through reasonable diet and regular exercise can also improve insulin resistance and reduce sodium retention, which are beneficial to lowering blood pressure.

The weight loss rate should be controlled at 0.5-1 kilogram per week, as rapid weight loss may lead to electrolyte imbalance. For people with a body mass index exceeding 28, the effect of weight loss and blood pressure reduction is particularly significant. However, the effectiveness of weight loss alone in controlling blood pressure is limited, and a combination of medication and lifestyle interventions is still needed. Patients with moderate to severe hypertension cannot stop taking medication without authorization while losing weight, and must adjust their medication plan under the guidance of a doctor. Patients with hypertension should mainly adopt a low salt and low-fat diet for weight loss, with a daily salt intake not exceeding 5 grams. It is recommended to choose coarse grains such as oats and buckwheat that are rich in dietary fiber, and consume more fresh vegetables and fruits. Engage in moderate intensity aerobic exercise for at least 150 minutes per week, such as brisk walking, swimming, etc. During the weight loss process, regular monitoring of blood pressure is necessary. If discomfort symptoms such as dizziness occur, seek medical attention promptly.
