When weight decreases, blood pressure decreases with it. The blood pressure and weight of the human body, in general, are often proportional, so for patients with abnormal blood pressure or hypertension, it is recommended that they must pay attention to exercise to lose weight, especially if there are obese or overweight patients. For patients whose blood pressure is at borderline values, it is expected to return to normal blood pressure after a good weight loss. However, patients with high blood pressure on a regular basis cannot treat hypertension by weight loss alone, but also need to improve their blood pressure in combination with antihypertensive medications. This is because no matter what the cause of the elevated blood pressure, as long as the blood pressure is persistently elevated, it will cause damage to the heart, brain, kidneys and other organs. While taking antihypertensive drugs, combined with a low-salt, low-fat diet, smoking cessation, alcohol cessation and weight reduction, this multifaceted treatment can control blood pressure at a more desirable level in order to better reduce or avoid complications. Therefore, overweight or obese patients must pay attention to weight loss in order to better control blood pressure within the ideal range.
