T67.5

Clinical Causes: Extended exposure to high temperatures and humidity Vigorous physical activity in hot weather Inadequate fluid intake leading to dehydration Failure to rest in cool environments during heat waves Certain medications that impair the body's ability to regulate temperature

Key Symptoms: Heavy sweating Weakness or fatigue Dizziness or lightheadedness Nausea or vomiting Headache Muscle cramps Paleness of the skin Elevated core body temperature (less than 104°F or 40°C)

Diagnosis Path: Diagnosis of heat exhaustion is primarily based on clinical evaluation, including assessing symptoms and medical history. Physical examination might reveal signs like sweating, dehydration, and low blood pressure. In some cases, doctors may perform blood tests to evaluate electrolyte levels or other laboratory tests to exclude other conditions. Monitoring vital signs and core temperature helps confirm the diagnosis. No specific tests are required for diagnosis, but they can aid in assessing the severity and guiding treatment.

Treatment Protocols: Treatment for heat exhaustion involves rapid cooling and rehydration. Key steps include: - Moving the affected individual to a cooler, shaded environment - Removing excess clothing - Giving cool water or electrolyte-containing drinks to rehydrate - Applying cool, damp cloths to the skin - Resting to allow the body to recover In some cases, intravenous fluids may be necessary for severe dehydration. It is crucial to monitor the individual's condition and seek emergency medical attention if symptoms worsen or if symptoms such as confusion, fainting, or vomiting persist. Prevention strategies include staying well-hydrated, avoiding strenuous activity during peak heat, wearing lightweight clothing, and taking regular breaks in shaded or air-conditioned environments.
