Low blood pressure and heart disease

Weakened heart muscle: There is a strong relationship between heart and blood pressure. If your heart is strong, there is almost no problem with your blood pressure. But if the heart muscle is weak, it will reduce the amount of blood it pumps. There are so many causes of weak heart muscles. Some of these include the death of a large portion of the heart’s muscle due to heart attack, medications that are toxic to the heart, infections of the muscle of the heart by viruses and the like.

Pericarditis: It is an inflammation of the pericardium. This is a condition in which, fluid starts accumulating within the pericardium and around the heart which finally disable the heart to pump blood and thus results the low blood pressure.

Pulmonary embolism: In this condition a blood clot in a vein breaks off in many diminutive parts and goes to the heart and finally reaches the lung. The small or large part of the blood clot can obstruct the flow of blood into the left ventricle from the lungs. It can also restrict the ability of the heart to pump blood leading to the development of the low blood pressure.

Low blood pressure due to low blood volume

Dehydration: Moderate to severe dehydration may lead to orthostatic hypotension. Dehydration is a condition which arises in a patient with diarrhea. In diarrhea, patient loses large amount of water. It can also occur because of the prolonged vomiting and nausea. There are also some other cause of the dehydration which include exercise, sweating, fever, and heat exhaustion.

Blood bleeding: Blood bleeding can also cause low blood pressure. Moderate or severe bleeding can in no time drain an individual’s body of blood, causing low blood pressure. Trauma, surgical complications, and from gastrointestinal abnormalities such as ulcers, tumors, are the main points of bleeding.

Medications and low blood pressure
Frequent medication can also cause low blood pressure. Medications such as calcium channel blockers, beta blockers, and digoxin can slow the rate at which the heart contracts and thus cause low blood pressure. Medications used to treat high blood pressure and depression can cause low blood pressure as well.

Apart from all these above mentioned causes of the low blood pressure, here are some of the other potential causes of low blood pressure found in many patients.

1) Intake of alcohol and narcotics.

3) Side effects of other prescription or over-the-counter medications
4) Pregnancy
5) Heat stroke or heat exhaustion
6) Various types of liver diseases
7) Crash diets
8) Anemia
9) Wide, dilated blood vessels
10) Weakened heart contraction
11) Obstructed blood flow due to defective heart valves or other reasons.

These are some of the basic causes of the low blood pressure. After identifying the cause of low blood pressure, you should immediately bring the desired lifestyle change in your living and meet doctor for further medical guidance.
