How Is Secondary Hypertension Diagnosed?

After you’re diagnosed with high blood pressure, your doctor may do other tests such as blood and urine screening to make sure you don't have secondary hypertension.

Your doctor may also choose to treat you with blood pressure drugs in addition to addressing the underlying health issues.
