PPH-What is it?
Primary(unexplained) pulmonary hypertension
(abnormally high blood pressure) is an extremely rare
lung disorder. Pulmonary hypertension occurs when there
are changes in small blood vessels in the lungs resulting
in an increased resistance to move enough blood through the
lungs. The resistance places a strain on the right ventricle
which must work harder to pump enough blood. If untreated,or
if the conditions are generally bad enough,the right side of
the heart may fail resulting in death.

PPH-What are the causes?
There is no definite cause of PPH,but there are possibilities.
1.PPH may be the result of another infection such as heart
disease,lung disease,or HIV.
2.PPH may be genetic. A specific chromosome which runs in
families is linked to PPH although the type of defect is yet unknown.
3.Familial Inheritance
4.Diet Drugs-By far this is the most known cause.
Fen-Phen and Dexfenfluramine,2 diet drugs have been
studied and are linked to numbers of cases of pph.
These drugs can cause PPH in as little as 23 days
the risk increases with the amount of time it is used.
5.Serotonin-Although this is not proved,it is believed
that the above diet drugs increase the release of serotonin
which is often found in patients transplanted lungs with PPH.
It is very possible that this is a cause

What are the symptoms of PPH?
In the early stages of PPh there are no symptoms. Usually
a person will go to the doctor for another disease and will
find that it can't be cured. After numerous tests,PPH is found
to be the primary cause....
