Can MH symptoms be induced by stress, overheating or excessive exercise?
The symptoms of heat exertion and heat stroke are remarkably similar to MH. However, the vast majority of patients who suffer heat-related illness are not MH susceptible. In a few cases, MH susceptibility has been diagnosed by muscle biopsy in patients who have suffered from heat stroke (non-fatal), and some experts believe that heat stroke may occur more often in MH-susceptible individuals. This is an area of intense interest and investigation. The general advice for MH susceptibles is to be prudent in their exposure to excessive heat and exercise in hot environments. The same advice should be given to patients who are not MH susceptible.
