Complications
By Mayo Clinic staffHeat rash usually heals without problems, but complications sometimes occur, such as:
- Infection. Occasionally, heat rash becomes infected with bacteria, causing inflamed and itchy pustules. This can occur in children in diapers but shouldn't be confused with diaper rash, which results from irritation to tender skin, not from blocked pores.
- Heat exhaustion. In hot weather, people with miliaria profunda are at risk of heat exhaustion, because their sweat ducts are blocked. Heat exhaustion can cause low blood pressure, dizziness, nausea, headache and a rapid pulse. Untreated heat exhaustion can lead to heatstroke, a life-threatening condition.
