Blood pressure often increases as weight increases. Being overweight also can cause disrupted breathing while you sleep (sleep apnea), which further raises your blood pressure. Weight loss is one of the most effective lifestyle changes for controlling blood pressure. Losing just 10 pounds (4.5 kilograms) can help reduce your blood pressure.
Besides shedding pounds, you generally should also keep an eye on your waistline. Carrying too much weight around your waist can put you at greater risk of high blood pressure.
These numbers vary among ethnic groups. Ask your doctor about a healthy waist measurement for you.
