T67.3
Heat exhaustion, anhydrotic
Clinical Classification Guidelines
Inclusion Terms
- Heat prostration due to water depletion
Excludes Type 1
- heat exhaustion due to salt depletion (T67.4)
Medical Intelligence & Overview
Heat exhaustion, anhydrotic, also known as heat prostration due to water depletion, is a condition that occurs when the body becomes overheated and loses an excessive amount of water and electrolytes. This form of heat exhaustion is characterized by minimal or absent sweating, which distinguishes it from other types where sweating is a primary symptom. It typically affects individuals exposed to high temperatures and humidity, especially during intense physical activity or inadequate fluid intake. Recognizing the symptoms early can help prevent progression to more severe heat-related illnesses, such as heat stroke.
Causes & Symptoms
Clinical Causes: Prolonged exposure to high environmental temperatures Intense physical activity, especially in hot and humid conditions Inadequate fluid intake leading to water depletion Inability to cool the body effectively due to environmental factors or wearing heavy clothing Certain medications that impair sweating or body temperature regulation Underlying health conditions affecting hydration and temperature control
Key Symptoms: Weakness and fatigue Dizziness or lightheadedness Headache Nausea or vomiting Rapid heartbeat (tachycardia) Weak pulse Muscle cramps dry skin and dry mucous membranes due to lack of sweating Decreased urine output or dark-colored urine Confusion or altered mental state
Diagnostic & Treatment
Diagnosis Path: The diagnosis of anhydrotic heat exhaustion involves clinicians reviewing the patient’s medical history, recent activities, and environmental exposure. Physical examination will focus on signs of dehydration, skin state, and neurological status. Blood tests may be ordered to evaluate electrolyte balance, kidney function, and overall hydration status. Monitoring vital signs, especially body temperature, pulse, and blood pressure, is crucial. Since anhydrotic heat exhaustion involves absent or minimal sweating, the clinical presentation may differ from typical heat exhaustion, making diagnosis based on physical signs and history essential.
Treatment Protocols: Treatment aims to rapidly cool the individual and replace lost fluids and electrolytes. Immediate steps include:
