Why would your diastolic blood pressure be 47?

A diastolic blood pressure of 47 mm Hg is considered abnormally low and potentially dangerous. It can indicate a medical condition such as:

1. Sepsis: A life-threatening condition caused by an overwhelming immune response to an infection.

2. Hypothyroidism: An underactive thyroid gland, which slows down your metabolism and affects blood pressure.

3. Addison's disease: Insufficient production of hormones by the adrenal glands, which can cause low blood pressure and other symptoms.

4. Medications: Certain drugs, such as diuretics, alpha-blockers, and beta-blockers, can lower blood pressure as a side effect.

5. Severe dehydration: A significant loss of fluids can lead to reduced blood volume and lower blood pressure.

6. Severe bleeding: Excessive blood loss through injury, heavy menstrual bleeding, or other conditions can cause low blood pressure.

7. Heart conditions: Some heart problems, such as a heart attack, certain arrhythmias, or severe aortic stenosis, can impair the heart's ability to pump blood effectively, resulting in low blood pressure.

8. Vasovagal response: A severe form of vasovagal syncope (fainting) involving a dramatic drop in heart rate and blood pressure.

If you have a diastolic blood pressure of 47 mm Hg, seek immediate medical attention, especially if you experience symptoms such as dizziness, fainting, weakness, or shortness of breath. Your doctor will determine the cause of your low blood pressure and recommend appropriate treatment.
