Morning , took my son for a visit to clinic and for the first time he had his blood pressure taken . he is 13 and had Downs syndrome. The blood pressure reading was 111/87. I thought this was a little high and so did the lady we saw, she said i shouldnt be too worried and just to get get it re -read at the next routine doctors appointment. Has anyone been in this situation , should i get it checked now and what would cause high blood pressure in a child. He isnt over weight and gets regular exercise.
