###Human: Should I consult a doctor for fluctuating blood pressures? ###Assistant: Hi. You need to test your blood pressure on a daily basis. The first thing in the morning and night time before you go to bed. You have to be resting for at least five minutes, and no food or drink for 30 minutes. Take the readings for one week. If it is, at the majority of times, above 140 then you need to consult a doctor. Otherwise, you need to have regular exercises, reduce salt, and caffeine.
