If the cause of low blood pressure is unclear and your doctor decides that raising your blood pressure should be your objective, then the following actions may help: * Adding more sodium to your diet * Wearing compression socks or stockings * Staying hydrated * Exercise (consult a medical professional about what type of physical activity can help lower blood pressure) **Low Diastolic Blood Pressure Complications** Low diastolic low blood pressure can lead to serious, sometimes life-threatening complications. * Falls: Those with low diastolic pressure can experience symptoms of fatigue or dizziness, which can lead to falls, especially dangerous for older people who may have brittle bones. * Heart problems: Low diastolic blood pressure can cause the heart to become stiff, increasing risk for diastolic heart failure. If the heart is stiff and doesn’t relax enough, it won’t be able to fill up with enough blood when it pumps.
