Low Diastolic BP: Causes, Symptoms, and Treatments
Low diastolic blood pressure occurs when the diastolic reading, which is the bottom number of a blood pressure reading, falls below 60 mm Hg. While many people focus on high blood pressure, low blood pressure can also be problematic and may cause symptoms such as dizziness, fainting, and fatigue. In this article, we will discuss the causes, symptoms, and treatments for low diastolic blood pressure.
Causes of Low Diastolic BP
Low diastolic blood pressure can be caused by a variety of factors, including:
- Dehydration: When your body loses too much fluid, it can cause a drop in blood pressure. This can happen if you don't drink enough water or if you sweat excessively.
- Medications: Some medications can cause low blood pressure as a side effect. These include drugs for high blood pressure, antidepressants, and diuretics.
- Heart problems: Certain heart conditions, such as heart failure or a heart attack, can cause low blood pressure.
- Hormonal imbalances: Disorders of the adrenal gland, such as Addison's disease, can cause low blood pressure.
- Infection: Severe infections such as sepsis can cause low blood pressure.
Symptoms of Low Diastolic BP
Low diastolic blood pressure can cause a variety of symptoms, including:
- Dizziness or lightheadedness: This is one of the most common symptoms of low blood pressure. You may feel like you're going to faint or lose your balance.
- Fainting: If your blood pressure drops too low, you may lose consciousness.
- Fatigue: Low blood pressure can cause you to feel tired and weak.
- Nausea: Some people with low blood pressure may experience nausea or vomiting.
- Blurred vision: Low blood pressure can cause vision problems such as blurred vision or tunnel vision.
Treatments for Low Diastolic BP
The treatment for low diastolic blood pressure depends on the underlying cause. Some possible treatments include:
- Increase fluid intake: If dehydration is causing your low blood pressure, drinking more fluids can help raise your blood pressure.
- Change medications: If a medication is causing your low blood pressure, your doctor may switch you to a different medication.
- Take salt: Adding more salt to your diet can help raise your blood pressure. However, if you have high blood pressure, this may not be a good option for you.
- Wear compression stockings: Compression stockings can help improve blood flow and raise your blood pressure.
- Treat underlying conditions: If an underlying medical condition is causing your low blood pressure, treating that condition can help raise your blood pressure.
Overall, low diastolic blood pressure can be a concern, especially if it causes symptoms. If you are experiencing symptoms of low blood pressure, it's important to talk to your doctor to determine the underlying cause and find an appropriate treatment.
