Neonatal edema

Edema is one of the common symptoms in the neonatal period. Its prominent manifestation is weight gain, which is caused by excessive accumulation of body fluids in the interstitial space, causing swelling of the whole body or local area. Those with edema and depression are called depression edema, and those with no depression are called non-depression edema. Fetal and newborn babies have physiological edema because they have more extracellular fluid than intracellular fluid. Systemic edema at birth is called fetal edema (hydrops fetalis), and often accompanied by serous fluid. This edema disappears on its own within a few days after birth. Edema caused by various causes after birth is called neonatal edema, which is more common in limbs, lower back, face and perineum.
