How Blood Pressure can be treated?
High blood pressure requires treatment and supervision by a doctor.
In cases where blood pressure is only slightly above normal, treatment may not be indicated. The doctor may simply periodically check your blood pressure to insure that it doesn’t go any higher.He/she may suggest lifestyle changes such as a low fat, low salt change in diet, a weight-loss program, an exercise program, quitting smoking and learning stress-reduction and relaxation techniques.
The physician may also include lifestyle changes as part of your treatment regime. If treatment becomes necessary, your doctor may prescribe drug therapy. Most people who need a blood pressure control drug require lifelong treatment. Therefore, you should never stop taking your medication simply because your high blood pressure has been controlled; consult your doctor first. In those few cases where a specific cause of high blood pressure (kidney disease, tumor, etc.) can be found, it’s sometimes possible to cure high blood pressure, but in most cases high blood pressure must be controlled throughout one’s lifetime.
