Is shortness of breath during everyday activities a warning sign of pulmonary hypertension?

Pulmonary hypertension (PH), a serious lung and heart condition, elevates blood pressure in lung arteries, causing shortness of breath even during simple tasks. This strain can lead to right heart failure if left untreated. Symptoms include weakness, chest pain, dizziness, and swollen limbs. Early diagnosis is crucial, involving tests like echocardiograms and lung function tests.
