Redness under the eyes is usually not food retention and may be caused by physiological factors or eye diseases.
Accumulation of food generally refers to indigestion, which may cause early satiety, fullness after meals, loss of appetite, burping, nausea, vomiting and other digestive symptoms.
Redness under the eyes can be caused by physiological factors, such as lack of sleep and overuse of the eyes, which can cause congestion of the conjunctiva and eventually lead to redness under the eyes.
In addition, redness under the eyes can also be caused by eye allergies and eye infections, in which eye allergies are accompanied by different degrees of itching, burning, redness and swelling of the throat, while eye infections can be characterized by localized redness, swelling, pain and other symptoms.
It is recommended to visit a hospital and ask the doctor to make a judgment if you have redness under the eyes.
