Complications
By Mayo Clinic staffHeat-related illnesses are the most serious complications of anhidrosis. Children are especially vulnerable because their core temperature rises faster than an adult's does, and they dissipate heat less efficiently. All children should be monitored closely for overheating, but extra precautions should be taken when a child has anhidrosis.
Heat-related problems include:
- Heat cramps. These muscle spasms, which can tighten muscles in your legs, arms, abdomen and back, are generally more painful and prolonged than are typical nighttime leg cramps.
- Heat exhaustion. Symptoms such as weakness, nausea and a rapid heartbeat usually begin after strenuous exercise. Anyone with heat exhaustion should be monitored carefully because symptoms can quickly become worse.
- Heatstroke. This life-threatening condition occurs when your body temperature reaches 104 F (40 C) or higher. If not treated immediately, heatstroke can cause hallucinations, loss of consciousness, coma and even death.
