I echo what others have said about diet, exercise etc. But some people (like me) cant control it with lifestyle changes no matter how good they are about it. Some people just need meds to control their BP.

In the large majority of situations, your family doctor can take care of your BP. AOPA has some good information on hypertension:

If it can be controlled with an acceptable med, it is a real easy process.
