I'm 25 and a dr logged my blood press at 186/85. i had a coffee an hour before. would that impact my bp that drastically or should i be very concerned?

Should be concerned: Cofee can be attributed to systolic elevation around 10 only & so wake up & pay attention to lowering BP. Start with Lifestyle modification.If ,lose wt-daily 30 min walk,yoga,meditation. Low carbohydrate,high protein diet with of fresh veg & fruits & nuts. Incorporate grilled or baked fish & chicken. Keep daily record of your BP. If lifestyle modification does not lower BP,need to go on medication
