Low blood pressure, otherwise known by the medical term hypotension, is a condition in which the blood pressure falls below the normal range. Blood pressure is determined by measuring the pressure of the blood within the arteries when the heart is actively beating and the rest period between beats. When your blood pressure dips below the normal range, it can cause a variety of health problems. Some people may not experience any symptoms, while others may feel lightheaded, dizzy, or experience a rapid heart rate. Many factors can cause hypotension. Here are 15 common causes.
Dehydration is a common problem that can cause low blood pressure. When the body doesn’t have enough water, blood volume decreases, which can lead to a drop in blood pressure. Dehydration can be caused by a variety of factors such as excessive sweating, vomiting or diarrhea, not drinking enough fluids, or taking diuretics. Some groups of people are at an increased risk for dehydration, including older adults, young children, and people with chronic illnesses. Symptoms of dehydration can include thirst, dry mouth, weakness, lightheadedness, and dizziness. If you think you might be dehydrated, drink plenty of fluids and see your doctor if the symptoms don’t improve.
