Hi, Thanks for posting in HCM. I understand your concern. Experiencing weakness and low blood pressure is a known phenomenon following heat stroke, which occurs due to hypotension. However, this fall in blood pressure is temporary. The body tries to recover back to normal in a couple of days. All you need to do during this period is to replenish fluids as much as possible by consuming water and fruit juices along with oral rehydration solution (ORS). You need to continue to take blood pressure medications as prescribed once blood pressure restores back to normal. Kindly consult Physician in this regard in case you need to clarify anything. Hope the information provided would be helpful. All the best.
