There are many ways to increase your blood pressure, like eating fast food, but in the same time you don t want kill yourself. Eating fast food will raise your blood pressure levels but it will raise your cholesterol levels, which can lead to heart attack, and makes you fat as a start. Salt is also not good so I would say you may drink come coffee to raise your blood pressure. Some coffee so not much, try to exercise (if you don t have heart issues or other health issues). If nothing has worked for you then might need a medication to put your blood pressure in normal ranges.
