Pulmonary Arterial Hypertension (PAH)

Pulmonary arterial hypertension (PAH) is a condition where the blood vessels in the lungs become narrowed or blocked, making it harder for blood to flow through them. This causes increased pressure in the pulmonary arteries—the vessels that carry blood from the heart to the lungs. The heart then works harder to pump blood, which can weaken it over time. Symptoms often include shortness of breath, fatigue, and dizziness. PAH can be caused by various factors, including genetics or other health conditions, and it requires medical management to control symptoms and improve quality of life.
