Dark spots around the patient’s eyes may be caused by pigment accumulation, endocrine disorders, light stimulation, hormone abnormality and so on. 1. Pigment accumulation: dark spots around the eyes may be related to one’s own physical condition and may be caused by pigment accumulation. 2. Endocrine disorders: patients with endocrine disorders may suffer from insomnia if their thyroid function is abnormal, which may lead to dark spots around the eyes. 3. Light stimulation: If the patient is exposed to sunlight and strong radiation light source for a long time, melanin synthesis will be accelerated, leading to the manifestation of dark spots around the eyes. 4. Hormonal abnormality: during pregnancy, due to the stimulation of progesterone, the secretion of luteinizing hormone in the body will increase, so pregnant women may have dark spots around the eyes. It is recommended that patients with dark spots around the eyes and other discomforts should consult the doctor in time to evaluate their conditions and follow the doctor’s instructions for treatment.
