AI Article Synopsis

  • A young, fit man suffered from severe heat stroke after running a 10 km race, despite being in good physical shape.
  • He had undergone a surgical procedure called bilateral thoracic sympathectomy to reduce sweating, which left him with limited sweating in his upper body and limbs.
  • This case highlights the importance of understanding how reduced sweating and altered body responses can increase the risk of heat-related illnesses in individuals who have had this type of surgery.

Article Abstract

We report the case of a physically fit young man who presented with severe, life-threatening heat stroke after running a 10 km road race. He had previously received bilateral thoracic sympathectomy for axillary hyperhidrosis at another hospital, and was known to have upper body and limb anhidrosis. Thoracic sympathectomy can result in reduced sweating and disturbed peripheral vascular and heart rate responses. Patients should be warned that these mechanisms may play a role in the development of exertional heat stroke.
