A blood pressure reading of 200/180 does not fall within the range for a normal blood pressure and is considered to be stage 2 hypertension, as stated by Mayo Clinic. Normal blood pressure readings are 120/80 or below for most individuals.
Readings over 120/80 but under 140/90 are indicative of prehypertension. Individuals with readings between 140/90 and 159/99 have stage 1 hypertension. Those with prehypertension and stage 1 and 2 hypertension are advised to make healthy lifestyle changes, while patients with stage 1 and 2 hypertension are advised to also consider blood pressure medications.
For adults 60 and older, normal readings can be up to 149/89, if they are otherwise healthy.
