P70-P74: Transitory endocrine and metabolic disorders specific to fetus and newborn

The group of conditions referred to as transitory endocrine and metabolic disorders specific to the fetus and newborn include a range of temporary hormonal and metabolic issues that can occur in newborns. These conditions result from disruptions in the fetus's endocrine system, the group of glands that produce hormones that control important functions within the body, or metabolic systems which are responsible for breaking down substances to create energy. Symptoms can vary depending on the specific disorder and may range from mild to severe. Some common signs include difficulty feeding, sleepiness, irritability, or jaundice. These disorders typically develop in the womb or shortly after birth, but the majority of them are transient, meaning they resolve on their own as the baby matures and develops. However, they may require close monitoring during the newborn period to ensure they don't progress into more serious complications.
