<s>[INST] Hi, I have a couple of questions if that's ok to do so.... I have 155/78 blood pressure with a resting 49 pulse. I'm 18 years old and weigh 189 lbs and I'm a male, I work full-time for a summer job which requires lots of cardiovascular exercise, so I would assume I'm getting enough physical activity throughout the days. Just curious if this is normal or if I have a high-blood pressure... If not, then another query would be required regarding why am I always so tired during whatever time it is. I eat healthily, I'm not exactly a couch potato, and I really can't find another explanation other than if I had high blood pressure, I'm not under much stress either at the moment..... Anyways, thanks, and please excuse the wall of text, I know how unattractive they are to read. [/INST] Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. 155/78 is more than normal and 49 pulse is slow. I will suggest that you should take ECG and stress echocardiography. If both come normal then start tab Amlodipine for blood pressure. Also start a multivitamin antioxidant combination once a day. Hope I have answered your query. Let me know if I can assist you further. </s>
