Low Diastolic Blood Pressure: Symptoms, Causes, and Treatments
If you have a low diastolic pressure, it means you have a low coronary artery pressure, and that means your heart is going to lack blood and oxygen. That is what we call ischemia, and that kind of chronic, low-level ischemia may weaken the heart over time and potentially lead to heart failure.
A 2016 study that lasted more than 3 decades and involved more than 11,000 people found that a diastolic blood pressure below 60 mm Hg is dangerous. People with this level are 50 percent more likely to have heart damage. This is compared with those who have a low diastolic pressure level between 80 and 89 mm Hg.
- Use more salt. Experts usually recommend limiting salt (sodium) because it can raise blood pressure, sometimes dramatically. ...
- Drink more water. Fluids increase blood volume and help prevent dehydration, both of which are important in treating hypotension.
- Wear compression stockings. ...
What is Low Diastolic Blood PressureBlood pressure is the force of blood pushing against the walls of your arteries. It’s measured with two numbers: systolic pressure and diastolic pressure.
- Systolic blood pressure: Systolic blood pressure measures pressure when your heart beats and pushes blood from the heart to the rest of the body.
- Diastolic blood pressure: Diastolic blood pressure measures pressure in blood vessels between heartbeats, when your heart relaxes and its chambers fill with blood.
Symptoms of Low Diastolic Blood PressureLow diastolic blood pressure may cause the following symptoms:
Symptoms of low diastolic blood pressure and low systolic blood pressureThe following are symptoms of low diastolic blood pressure and low systolic blood pressure (hypotension):
- Dizziness or lightheadedness
- Blurred or fading vision
Cause of Low Diastolic Blood PressurePregnancy and heart conditions, such as low heart rate, heart valve disorders, and heart failure, can lead to low diastolic blood pressure. Aging is another risk factor, as well. As you age, your vessels become stiff, which can prevent enough blood and oxygen from flowing back into the heart. Low diastolic blood pressure can also be caused by medications and lifestyle factors.
MedicationsMedications, especially ones that are prescribed for hypertension, are common causes of low diastolic blood pressure. Alpha blockers (central acting anti-hypertensive agents) can lower your diastolic blood pressure more than your systolic blood pressure. Other medications that can lead to low diastolic blood pressure include erectile dysfunction drugs, tricyclic antidepressants, Parkinson’s disease drugs, beta blockers, and diuretics.
LifestyleLow diastolic blood pressure can also be caused by diet, including not drinking enough water, which lowers the overall blood volume.
Cause of General Low Blood PressureWhile blood pressure may vary throughout the day, certain medications, medical conditions, and lifestyle factors can cause persistently low blood pressure.
MedicationsTaking the following medication can lead to low blood pressure:
- Alpha blockers
- Beta blockers
- Certain types of antidepressants
- Erectile dysfunction medication
- Parkinson’s disease medication
Medical conditionsThere are various medical conditions that can cause low pressure, including:
- Heart conditions, including low heart rate (bradycardia), heart attack, and heart failure
- Thyroid and adrenal issues
- Severe infections
- Severe allergic reactions
LifestyleLack of vitamin B12, iron, and folate in your diet can lead to low blood pressure, since these nutrients help your body produce enough red blood cells. Having an insufficient amount of red blood cells can lead to low blood pressure.
Treatment of Low Diastolic Blood PressureTreatment of low diastolic blood pressure depends on the primary cause of the hypotension. If you have low blood pressure, you should see a medical professional right away. They will perform an assessment, determine the cause of your low blood pressure, and recommend a treatment plan.
Treating isolated low diastolic blood pressureIf low diastolic blood pressure is caused by medication, your doctor may adjust your dosage or change your prescription. They will address any contributing lifestyle factors and also evaluate for serious underlying causes of your low blood pressure. Lifestyle changes can also help, including getting exercise, maintaining a healthy weight, and refraining from smoking.
Treating general low blood pressureLow blood pressure that is mild and doesn’t cause symptoms often doesn’t need treatment. But for those with symptoms, treatment will be based on the cause if it’s identifiable. If you’re taking medication that’s causing low blood pressure, you may have to change medication or adjust dosage based on what your doctor determines. 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: If you have persistently low blood pressure, then adding more salt to your diet may help. But it’s important to consult your doctor before increasing salt intake, since too much salt can cause serious medical issues, such as high blood pressure and heart failure.
- Wearing compression socks or stockings: This can help improve circulation by reducing the pooling of blood in your legs.
- Staying hydrated: Drinking enough water prevents dehydration, which reduces blood volume. Low blood volume leads to low blood pressure.
- Exercise: Consult a medical professional about what type of physical activity can help lower blood pressure.
