Blood pressure can also drop after eating among older people. In those cases, medications are not the best approach, but replacement of lost fluid volume and patients are treated with IV fluids in a hospital setting.

I’m just giving two extreme examples here, one of a normal physiological state, and one of a severely life-threatening, pathophysiological state, both of which include low blood pressure as a “symptom” so you can see why “low” blood pressure is not sufficient for any determination of health or disease, and why you need to address this with a physician who knows the rest of your history and other findings of a physical exam to determine if there is any reason to be concerned by your blood pressure.

BP and Heart Diseases
Reducing your risk of heart disease could be as easy as changing up the type of carbs you eat from refined carbs to whole grains. In fact, according to recent studies, eating just one serving of whole grains can reduce your risk of high blood pressure by 4%.

However, under some circumstances administration by injection of a single or repeated dose of the antidepressant drug is desirable. This may be so if it is important to attain adequate blood level of the drugs rapidly, or if a patient is unable to take the drug orally.

Also try Beta Blockers
Also, Beta-blockers, which reduces heart rate and pumping of the heart, brings about low BP. Even over-the-counter medicines cannot be ruled out in the context of your having a low pressure. If someone is on high blood pressure medication or has heart problems, the blood pressure drop can be even more significant. Blood pressure refers to the pressure of the blood when it is pumped from the heart. There are two different types of blood pressure, the systolic and diastolic.
