Sunken eyes in newborns

Sunken eyes in newborns: Sign of severe dehydration

Sunken, "sunken" eyes — this is one of the classic clinical signs of severe dehydration in newborns. This symptom indicates a moderate or even severe degree of dehydration and is a "red flag" that requires close attention and, in most cases, seeking medical care. Unlike dry mucous membranes, which appear at early stages, sunken eyes indicate a more serious fluid loss.

Why do the eyes "sink"?

The eyeball sits in the eye socket (orbit) and is surrounded by fatty tissue and other soft tissues that consist largely of water. They act as a kind of "cushion". When the body loses a significant amount of fluid, the volume of these tissues decreases. They essentially "deflate", causing the eyeball to appear deeper in the orbit. This effect is amplified by loss of skin elasticity around the eyes.

Sunken fontanelle — a concurrent dangerous symptom

Very often sunken eyes are accompanied by a sunken large fontanelle (soft spot on the infant's head). The mechanism is the same — a reduction in body fluid volume, including the volume of the brain and cerebrospinal fluid, leads to the fontanelle "caving in". This is also a sign of severe dehydration.

What does this mean for parents?

The appearance of sunken eyes indicates that the child's body has already lost about 5-10% of its fluid. This symptom is rarely isolated and is usually accompanied by other signs of moderate and severe dehydration, such as lethargy. If you notice sunken eyes in your child, this is a direct indication to seek medical attention immediately.
