P80: Hypothermia of newborn

Hypothermia of newborn, also known as neonatal hypothermia, is a serious condition that occurs when a baby's body temperature drops below the normal range. This condition typically affects newborns within the first few days of life. It is mostly caused by exposure to cold environments, inadequate clothing, delayed drying and warming at birth, and premature birth. The primary symptom is a low body temperature, usually under 36.5 degrees Celsius (97.7 degrees Fahrenheit). Other signs can include cold skin, lethargy, weak suckling during feeding, and a weak or high-pitched cry. If untreated, hypothermia can lead to poor feeding, weight loss, slowed growth, and in severe cases, it can be life-threatening. This condition mainly affects the metabolic, immune, and nervous systems, potentially disrupting the normal functioning of these systems. Though it typically results from environments the newborn is exposed to, it can indirectly be passed on if the mother is in cold conditions.
