New blood pressure guidelines are relaxing the limits for which adults would need to start treatment.
The guidelines suggest increasing the limit for which people over 60 would need medication for their high blood pressure, which is up from 140 over 90 to 150 over 90.
People under 60 would start drug therapy when their blood pressure levels reach 140 over 90, compared to 130 over 80 as suggested in past guidance.
There are exceptions based on race and whether patients have diabetes and kidney disease. The researchers say there weren't enough data to support making this recommendation a lower number.
Outside experts say increasing the limits might mean some people will experience the damaging effects that elevated blood pressure can have on the body.
