T67.2

Clinical Causes: Excessive sweating leading to loss of electrolytes such as sodium, potassium, and magnesium Dehydration Prolonged physical exertion in hot and humid conditions Inadequate acclimatization to hot environments Muscle fatigue from overuse or strain

Key Symptoms: Sudden, painful muscle contractions, often in the calves, thighs, or abdominal muscles Muscle soreness and tenderness Muscle twitching or hardening Weakness in the affected muscles Swelling or cramping that can last from seconds to minutes

Diagnosis Path: Diagnosis of heat cramps is primarily clinical, based on a patient’s history of exposure to hot conditions, recent physical activity, and characteristic symptoms. Physical examination may reveal tender, tightly contracted muscles. Healthcare providers may inquire about fluid intake and electrolyte balance but typically do not require laboratory tests for diagnosis. It is important to distinguish heat cramps from other heat-related illnesses such as heat exhaustion or heatstroke.

Treatment Protocols: Management of heat cramps focuses on relieving symptoms and preventing further dehydration or electrolyte imbalance. Common strategies include: - Resting in a cool, shaded place - Gently stretching and massaging the affected muscles - Replenishing lost fluids with water or electrolyte solutions - Consuming foods rich in electrolytes, such as bananas or sports drinks In severe cases, medical attention may be necessary to administer intravenous fluids or electrolytes. Individuals should avoid strenuous activity until fully recovered and should consider measures to prevent future episodes, including adequate hydration and gradual acclimatization to hot environments.
