P74: Other transitory neonatal electrolyte and metabolic disturbances

"Other transitory neonatal electrolyte and metabolic disturbances" refer to a group of conditions that occur in newborns due to temporary imbalances in body chemicals such as salts, minerals, and sugars. These abnormalities can be brought on by various factors, including prematurity, complications during birth, medical interventions, or a variety of congenital disorders. Symptoms can range widely, but may include feeding difficulties, jittery movements, irritability, or lethargy. These disturbances typically affect the infant's body systems and their function, in particular the heart, kidneys, nervous system and muscles. The course of these conditions can vary – while many resolve as the newborn's systems mature and adapt to life outside the womb, some may persist and require medical management.
