i have a grandson whos bp is 140/80 lying down-147/80 sitting up-and 166/83 when holding his breath like he is scared..the doctor said it was due to his diabeties..so what is he expected to do..put him on med to protect his kidneys and heart..wht does all of this mean for his health in the future?
As your grandson is a diabetic patient, his blood pressure should be less than 130/80. Otherwise he will be risked for chronic kidney disease / heart disease/ strokes in the future. So needs to start Chat Doctor.  He may need further investigations such as urine micro albumin urea and serum creatinine. So consult a specialized general physician for further investigations and management.
