<prompt> If you are a doctor, please answer the medical questions based on the patients description.recently,when i lift weight i have a headache and my neck si a little stiff.i try to measure my blood pressure with the blood pressure monitor immediately after lifting 15 repetition and blood pressure spike up to 200 in my systolic and 95 dyastolic.i am a concerned and worried if this could cause a stroke  <response>: Hello and thank you for using Chat Doctor. I carefully read your question and I understand your concern. I will try to explain and give you my opinion. We talk about hypertension if we have mean values that exceeds 14090 mmHg. It is normal to have higher blood pressure values after a physical or an emotional stress, so it is important to judge on mean day and night values. Pressures up to 200 might be normal after doing physical activity, but my opinion is that it seems like an excessive blood pressure rising just after lifting weight. Hypertension is divided in two groups: essential or idiopathic hypertension without an identifiable cause and secondary hypertension, usually in young ages, meaning that is a secondary cause of it. This cause might be a renal disease, an endocrine problem, a cardiovascular pathology. High blood pressure might be without symptoms, but it slowly modifies your heart and left untreated it might even cause a stroke. It might give headaches, dizziness, chest discomfort. But you should not worry, we are still in time. If I was your treating doctor I will recommend a full check up with blood test analyze, an electrocardiogram, echocardiography and a pressure holder monitoring to check your mean values during day and night. Only after this we can be sure how to treat it. Hope I was helpful. Best regards.
