Sunken lower eye sockets can be caused by malnutrition, dehydration and orbital fracture. Physiologic factors usually do not require treatment and can be improved by enhancing nutrition and drinking more water, while orbital fracture patients can have surgery to improve their appearance. 1. Malnutrition and wasting: patients with malnutrition can have sunken eye sockets due to large loss of body fat and protein. Normally, patients should pay attention to strengthen nutrition, try not to lose weight excessively which leads to wasting, and also pay attention to strengthen physical exercise, which can make the sunken lower eye sockets full again. 2. Dehydration: Dehydration is commonly seen in hot summer weather, short-term water intake is insufficient and too much evaporation due to sweating and other reasons, which will lead to dehydration, orbital content volume contraction, so that the patient’s eyes appear below the skin depression. It is recommended that patients drink more water, regulate the diet, and replenish the body with water, which can make the sunken lower eye sockets return to fullness. 3. Orbital fracture: Patients with orbital fracture may have sunken eye sockets, which can be treated by surgery, such as orbital wall repair, to improve the patient’s appearance. It is recommended that patients with obvious sunken eye sockets should consult a doctor to evaluate their condition and follow the doctor’s instructions.
