What are the stages of pulmonary hypertension?

There are 4 main stages of PH, which are based on the symptoms you have and how well you go about your normal life. They include:

• class 1 – when you don’t have any symptoms

• class 2 – when you don’t have symptoms at rest, but you feel discomfort during household chores and climbing the stairs

• class 3 – when you feel fine at rest, but it’s much harder to do normal tasks

• class 4 – when you have troubling symptoms, even at rest
