pulmonary artery hypertension

Pulmonary artery hypertension (PAH) is a condition where the blood pressure in the arteries carrying blood from the heart to the lungs becomes abnormally high. This increased pressure forces the right side of the heart to work harder to pump blood through the lungs. Over time, this strain can cause the heart to weaken and lead to symptoms like shortness of breath, fatigue, dizziness, and swelling in the legs. PAH can develop from various causes, including underlying health issues, and requires medical management to control symptoms and improve quality of life.
