Hello dear user! I have gone through your query and understood your concerns! Thank you for sharing them on healthcaremagic. First I would like to know some more information about your husband. How years old is he? What are the levels of blood pressure? At age over 50s people in general are affected by high blood pressure without any specific cause for that. It is called essential or idiopathic hypertension. You say in your query that your husband makes a healthy lifestyle, so we can ignore some of the factors that affect blood pressure. Related to your concerns I would say that, stroke is not the most common cause which leads to high blood pressure and it has a severe and bad clinic, but uncontrolled hypertension may lead to strokes. If the levels of hypertension remain high for some days, you may consider antihypertensive drugs to keep it undercontrol. Enalapril or valsartan is my favorite drug for this purpose of course taken by the pharmacist or doctor advise. Try to reduce salt in the diet. Meanwhile an analysis of sugar and lipids in blood must be done. If your husband has other complains or he have not any improvements after these measures, please feel free to write us again or talk with your family doctor at your healthcare center. I hope this answer was helpful to you! Please kindly rate it and write a short review about your experience with me! Thank you and best regards! DR ERIOL.
