What Causes Sunken Eyes? 12 Common Causes (You Should Know)

Dehydration

Dehydration is yet another common cause of sunken eyes, especially among children. Many things, including diarrhea, can cause it, along with overconsumption of coffee, soda, and prepackaged drinks with diuretic effects, peritonitis, inadequate fluid intake for extended periods, and increased urine production. 

It is often characterized by symptoms like excessive thirst, low urine output, and dry mouth. In severe cases of dehydration, lethargy and decreased responsiveness is also quite apparent. 

Dehydration affects the eyes. One doesn’t have to be severely dehydrated before it shows up as sunken eyes. However, according to experts, it is possible to tell the degree or severity of the dehydration by checking out how severe the eyeballs have receded into the eye socket. Among children, in particular, enophthalmos with diarrhea can be a symptom of some other serious underlying condition. 

To stay hydrated and keep your eyes from hollowing out, experts recommend maintaining euhydration, the optimal total body water content regulated by the brain, by drinking plenty of water and easing up on caffeine and alcohol. Taking electrolytes to replace extracellular deficits within 2 to 3 hours also works. Using skin products like moisturizers and beauty patches also draws moisture into the outer levels of the skin, allowing it to look plump and hydrated.
