How Viagra can help
to improve your health
Already hailed as the magical cure for sexual dysfunction, it is now becoming increasingly clear that Viagra may have other health benefits.
Viagra is the brand name of the generic drug Sildenafil. Viagra was introduced ten years ago and is beneficial not only for erectile dysfunction but also for other reasons. Because congestive heart failure is one reason of erectile dysfunction, some patients would refuse to take their heart medicine. Viagra has solved that problem. It is safe for heart patients. Research shows that heart patients are more apt to take their heart medication along with taking Viagra. Research has also discovered that patients who take sildenafil exercise more. It has been shown to lower blood pressure and heart rate; therefore, there is an improvement in oxygen and carbon dioxide production. Viagra improves self-esteem, relieves stress, provides better sexual relationships and improves the circulatory system with lower blood pressure and heart rate. Viagra has helped over 25 million men.
The market for erectile dysfunction medication in 2006 was about $3 billion for the drugs Viagra online and Cialis. At one time health professionals and market analyst estimated that the market would eventually grow to about $5 billion yearly however this has failed to materialise. The figures were based on looking at all men who suffered from erectile dysfunction in any form and assuming that all men would want to use erectile dysfunction medication, however this has not proved to be necessarily true. Some men have simply learnt to live with erectile dysfunction as they may not be in a relationship and therefore have decided to live without sex. Other men are simply too embarrassed to come forward with their condition and therefore have mentally blocked out the fact that there are unable to get sufficient erections for sex.
The makers of Viagra online namely Pfizer and Eli Lilly however can hardly complain about the sales of their drugs which have been phenomenal since they were launched just over a decade ago. While they are sure that sales will continue to increase it does seem that the market is pretty saturated at present and that the individual companies will only boost their sales by stealing existing market share from rivals.
When Viagra online was launched Playboy Magazine predicted that it would begin a revolution that would change the world and this to a certain extent has been true. Time Magazine predicted that Viagra would change "sex as we know it" and for many older men this is largely true too.
Viagra could help to treat people with a potentially life-threatening heart and lung condition known as pulmonary arterial hypertension (PAH). Around 250,000 people in the UK suffer from PAH, which causes high blood pressure in the arteries of the lungs (see case study).
Scientists believe that Viagra encourages blood vessels in the lungs to relax, preventing the constriction that causes hypoxia and sometimes pulmonary hypertension.
The world's first major study of the drug as an aid to fertility showed that it dramatically increased the chances of pregnancy in a certain group of women. The research, carried out by the American Sher Institute for Reproductive Medicine in Nevada, suggests it does this by aiding blood flow to the uterus. Thousands of women - around one in 20 of those who seek treatment - cannot conceive because their uterine lining is too thin.
Often these women cannot be helped by IVF - which involves implanting an embryo into their uterus - because the lining of their womb is not thick enough to support a pregnancy.
Viagara helps dilate blood vessels and seems to promote growth of the lining of the uterus without side-effects.
Viagra is safe for men with congestive heart failure (CHF) and because it lowers their heart rate and blood pressure during exercise (including sexual activity), tests show that it could even improve their condition.
In the past many CHF patients and their wives were often afraid that sexual activity could aggravate symptoms or even be fatal.
Up to 70 per cent of CHF patients also suffer from erectile dysfunction and many stop taking their heart medication, thinking it is causing the problem, so Viagra could also encourage them to keep taking the tablets.
Researchers at Johns Hopkins University School of Medicine in Baltimore found that Viagra may benefit people with gastroparesis or delayed stomach emptying.
Gastroparesis, which impedes digestion and causes dehydration and loss of appetite, is a problem for 75 per cent of diabetics.
The researchers found that Viagra helped relax animals' stomach muscles and have been conducting trials on human diabetics. It could help keep insulin and blood sugar levels on an even keel, which is vitally important.
Viagra may protect mountaineers from developing lung problems associated with high altitude.
German researchers testing Viagra on 14 expert climbers found that they could better tolerate hypoxia - lack of oxygen - while scaling a Himalayan peak.
The study also discovered that the drug had a similar effect at sea level opening up its potential as a sports performance enhancer.
It is not known if Viagra could improve lung function in healthy athletes in normal conditions as blood and lung vessels are already dilated and dilate more with exercise.
However it could improve performance-in racehorses, which sometimes suffer lung bleeding and edema after racing.
