what cause your blood pressure to drop
Many things can cause your blood pressure to be too low, ranging from normal pregnancy-induced changes to dangerous underlying conditions, like heart problems or hormone disturbances. In some instances, what causes low blood pressure could be a simple case of dehydration brought on by vomiting, intense exercise, or the overuse of diuretics. Some studies have shown that a dehydration-induced weight loss of 1 percent is enough to trigger dizziness, confusion, or other symptoms of low blood pressure.
Other important causes of low blood pressure include: 1  Heart problems that cause low heart rate, diminished heart strength, or a decrease in the amount of blood supplied to the body. 2  Normal changes associated with the first and second trimesters of pregnancy.
