Guest guest Posted January 13, 2008 Report Share Posted January 13, 2008 When I complained of shortness of breath, the doctor tested me for Hepatopulmonary syndrome. I tested positive, and the explanation given to us is as follows: Nitric oxide is what regulates the size of your blood vessels.If you are having a heart attack you get a nitro pill ,guess what it turns into in your body? Nitric oxide or NO. This is the exact effect that the drug viagra has on blood vessels. Viagra turns into NO, dialates the vessels. With HPS, the excess NO cant be cleared by the damaged liver, it builds up, and causes spleen enlargement, and also HPS. The capilarries in the base of the lungs becoms dialated. The blood flows too fast to get the oxygen attatched to it. Also the blood vessels are too large and the blood in the middle cant reach the oxygen anymore. http://www.ncbi.nlm.nih.gov/pubmed/16514571?dopt=Abstract http://www.cvphysiology.com/Blood%20Flow/BF011.htm ________________________________________________________________________________\ ____ Looking for last minute shopping deals?
