Low diastolic blood pressure

Diastolic blood pressure is the pressure of the blood on the arterial walls when the heart ends the contraction and relaxes. Systolic blood pressure is measured when the heart contracts and pushes the blood into the arteries. For a healthy adult person normal blood pressure is 120/80mg Hg. 120 represents the systolic blood pressure and 80 is diastolic pressure.

Diastolic pressure is always lower number than systolic blood pressure. Certain medical conditions are characterized by low diastolic blood pressure, fewer than 60mg Hg, which is also called low blood pressure or hypotension. Hypotension can also be caused by low systolic blood pressure, when this value comes under 90mg Hg. Low diastolic blood pressure is the risk factor for the development of hardened arteries and cardiovascular diseases.

Symptoms

A patient experiencing low diastolic blood pressure is usually thirsty, his/her skin is cold and pale, he’s nauseous and breathe very shallow and fast. In most cases, these people feel dizziness, lightheadedness or fainting.

If the drop in diastolic pressure is small it might not cause any health problem, but if it become too low, it can affect the supply of nutrients and oxygen and removal of the waste from the cells. If the condition lasts for a long time the consequence might be cellular death.

What Causes Low Diastolic Blood Pressure

There are a few different reasons and conditions associated with low diastolic blood pressure. Doctors will tell you that elderly normally have lower diastolic pressure than middle aged or young people. Low diastolic blood pressure in older people might be caused by aging and stiffening of the aorta, but also by hypertension medications. Drugs these patients use to lower high systolic blood pressure affect the diastolic pressure as well.

Pregnant women could also experience this condition in the middle of their pregnancy, around 24th week. In most cases, this condition in transient and their blood pressure comes back to normal after the childbirth.

People that suffer from a nutritional deficiency, dehydration, serious infections and allergic reactions like anaphylaxis, can also experience low diastolic blood pressure. It has also been associated with people who lost plenty of blood, experience heart failure, slow heart rate or some other heart problems. Pulmonary embolism may also lead to low diastolic blood pressure.

How to Treat This Condition

When there are no symptoms of low diastolic blood pressure there is also no need for the treatment.

However, if your diastolic blood pressure is constantly low, you should consult your doctor. He/she will be able to properly assess the condition and diagnose, if there is any, medical problem.
