Doctors are still arguing about the causes that provoke the pulmonary hypertension. According to one version, this dangerous disease can be caused by oral contraceptives, on the other – even the wrong weight loss. Pulmonary hypertension can occur in people with heart disease, thyroid disorders and liver disease, as well as in those with HIV infection.
Pulmonary hypertension literally forces patients to leave: decreased physical endurance, shortness of breath, cough, fainting, swelling of the feet and etc. Eventually there comes a heart failure. Sildenafil is one of the few substances that helps to overcome the tough disease; the dosage is appointed by the treating doctor.
