Introduction
In general, sunken eyes may result from factors such as aging, excessive fatigue and eye strain, malnutrition, dehydration, or hyperthyroidism. It is recommended to seek prompt medical evaluation at a hospital to determine the underlying cause and receive targeted treatment. In daily life, maintain healthy habits—avoid spicy and irritating foods (e.g., Sichuan pepper, chili peppers, garlic) to support recovery.
Generally, sunken eyes may result from factors such as aging, excessive fatigue and eye strain, malnutrition, dehydration, or hyperthyroidism. It is recommended to seek prompt medical evaluation to identify the underlying cause and receive targeted treatment. A detailed analysis follows:
1. Aging
As individuals age, subcutaneous fat, the orbicularis oculi muscle, and orbital septum fascia around the eyes gradually atrophy and become lax, diminishing their supportive function for the eyeball. This leads to posterior displacement of the eyeball and progressive hollowing of the eye sockets—a normal part of the human aging process. Symptoms typically begin to become noticeable around age 35. Daily eye care—including use of eye creams containing collagen and hyaluronic acid—may help mitigate this effect.
2. Excessive Fatigue and Eye Strain
Chronic sleep deprivation (e.g., frequent late-night activity), insufficient rest, or prolonged use of electronic devices can cause sustained tension in the periorbital muscles, accelerating water loss and fat depletion in the surrounding tissues. Additionally, systemic fatigue impairs circulation, reducing blood supply to the eyes and contributing to sunken eye sockets. It is advisable to ensure adequate sleep—7–8 hours per day—and minimize prolonged visual tasks.
3. Malnutrition
Long-term restrictive dieting, selective eating habits, or gastrointestinal disorders may lead to deficiencies in essential nutrients such as protein and fat, depriving ocular tissues of necessary nourishment. This results in reduced periorbital fat volume and subsequent hollowing. Patients often present with generalized weight loss and pallor. Dietary modifications—emphasizing balanced nutrition and increased intake of high-quality protein and healthy fats—are recommended.
4. Dehydration
Severe diarrhea, vomiting, profuse sweating, or disease-related polyuria can cause significant loss of body water and electrolytes, resulting in dehydration. Dehydrated skin and tissues around the eyes lose elasticity, leading to sunken eye sockets. Prompt rehydration with oral rehydration salts is appropriate for mild cases; severe dehydration requires intravenous fluid replacement therapy.
5. Hyperthyroidism
In patients with hyperthyroidism, excessive thyroid hormone secretion accelerates metabolism and stimulates the sympathetic nervous system, inducing structural changes in periorbital muscles and adipose tissue. This may manifest as coexisting exophthalmos (protruding eyes) and sunken eye sockets. Additional symptoms include excessive sweating, palpitations, and unintentional weight loss. Under physician guidance, antithyroid medications such as methimazole tablets or propylthiouracil tablets may be prescribed.
Adopting healthy lifestyle habits is important in daily life. Avoid spicy and irritating foods—such as Sichuan pepper, chili peppers, and garlic—as they may hinder recovery.
