    How to diagnose Pulmonary Hypertension ?
    ### Response:
    Your doctor will diagnose pulmonary hypertension (PH) based on your medical and family histories, a physical exam, and the results from tests and procedures.
                
PH can develop slowly. In fact, you may have it for years and not know it. This is because the condition has no early signs or symptoms.
