Causes Of Pulmonary Hypertension

Causes Of Pulmonary Hypertension           There are several causes of pulmonary hypertension and invariably more than one cause will be present. If you know the causes, then you can preventive measures from the very beginning, so that you do not get afflicted by this life-threatening condition. Some of the causes of pulmonary hypertension are discussed below.

 

Any disease that has an effect on the blood flowing out from the heart to the rest of the body can cause a backflow of the blood. This, in turn, could increase the pressure in pulmonary arteries resulting in pulmonary hypertension.

Another cause for pulmonary hypertension is constriction of blood vessels in the lungs. This constriction usually occurs when some part of the lungs is not functioning properly and the body tries to divert as much blood as possible from that area to proper functioning parts of the lungs, so that blood can be oxygenated. However, this causes the blood to contain low levels of oxygen. When oxygen levels in the blood are low, it causes the blood vessels to constrict, leading to a condition known as hypoxic pulmonary vasoconstriction. This, in turn, results in pulmonary hypertension.

At times, certain diseases can alter the pulmonary blood vessels, so that they become constricted. When this occurs, the blood has to force itself through the narrowed vessels resulting in pulmonary hypertension. The constriction of blood vessels can occur due to changes in the inner lining of the vessels, scarring or growth of tissue in the vessels.

A parasitic infection known as schistosomiasis is another reason for development of pulmonary hypertension. In this case, the parasite enters the blood vessels in the lungs causing an obstruction. The obstruction does not allow smooth flow of blood through blood vessels due to which blood pressure rises in the vessels. This parasitic infection is quite common in the Middle East.

Even certain medications can result in pulmonary hypertension. Medications to reduce weight can pressure to increase in pulmonary vessels. However, it is important to note that this rarely occurs, but the risk is always there. Hence, no medication to combat obesity should be taken without consulting a doctor first.

There are also unknown reasons for pulmonary hypertension. Here the doctors are unable to pinpoint the exact cause for the elevated pressure in the pulmonary blood vessels.

As you can see that there are several causes for pulmonary hypertension. If you think you may be suffering from this condition, it is best to consult a doctor immediately, as pulmonary hypertension is a life-threatening disease and the prognosis without treatment is not very good for patients.
