You don't say how much above normal it was and for how long or give details about your current physical state, just in case I'd recommend a general health check-up. My guess is that as most of us you don't do those regularly.

Hypertension is most of the times but not always caused by your life style choices and can be fixed (not dealt with) improving weight, diet, fitness level (chronic stress and caffeine/smoking are a factor too).

For diet recommendations you could look into DASH[1] to get an idea of the direction you should take.

Anyway, this is a good time to start improving your life style as any[2].
