Your doctor can prescribe a diet that's right for you. If you're given a diet, follow it closely, including any recommendations about reducing your consumption of alcohol. Alcoholic drinks are high in non-nutritious calories, so if you're trying to lose weight, avoid alcoholic beverages. Often when people lose weight, their blood pressure drops as well. If that's your situation, you will probably need to take medication.
Many medications are available to reduce high blood pressure.
Others relax constricted blood vessels. Others prevent blood vessels from constricting and narrowing. Because there is usually no cure for high blood pressure, treatment generally must be carried out for life. If treatment is stopped, the pressure may rise again. Generally, someone with high blood pressure will be on lifelong medication.
