Clinical Causes: Severe illness or infection that interferes with temperature regulation Prolonged exposure to water or moisture, such as in drowning or near-drowning incidents Metabolic or endocrine disorders like hypothyroidism or adrenal insufficiency Use of certain medications or drugs that impair thermoregulation or cause drowsiness Shock or trauma that affects blood circulation Mental health conditions affecting awareness or decision-making, leading to neglect of self-care Malnutrition or fasting, which can decrease body heat production Age-related factors, including in the elderly, where the body's response to temperature changes is diminished

Key Symptoms: Intense shivering or trembling Slurred speech and confusion Drowsiness or lethargy Weak pulse and slow heartbeat Difficulty maintaining coordination Redness or paleness of the skin Feeling cold despite warm surroundings In severe cases, unconsciousness or coma

Diagnosis Path: Diagnosing hypothermia not linked to environmental cold involves a combination of medical history assessment, physical examination, and laboratory tests. Healthcare providers will measure core body temperature, typically via rectal or esophageal readings, to determine if it’s below normal levels. Blood tests may be conducted to identify underlying causes such as infections, metabolic imbalances, or medication effects. Additional assessments include checking for signs of organ dysfunction or damage due to low body temperature.

Treatment Protocols: Managing this form of hypothermia involves stabilizing the patient and addressing the underlying causes. Treatment strategies may include: - Warming the body gradually using external methods like blankets, warm baths, or forced-air warming systems - Providing warm, humidified oxygen if respiratory issues are present - Administering intravenous fluids to maintain hydration and improve blood flow - Correcting metabolic or hormonal imbalances with appropriate medications - Monitoring vital signs closely to track recovery progress - Treating associated complications, such as infections or organ dysfunction In severe cases, hospitalization in an intensive care setting may be necessary to provide advanced support and prevent further deterioration.
