Pulmonary hypertension

Pulmonary hypertension is high blood pressure in the arteries of the lungs.

When you have this condition, your body gets less oxygen from your blood. This causes symptoms such as shortness of breath and feeling tired, faint, or dizzy. Over time, these symptoms may change or get worse if your heart gets weaker. You may get heart failure. Heart failure means your heart doesn't pump as much blood as your body needs.
