Doctor's answer (1)
Dr. Wang Shuai
The main symptoms of vitamin A deficiency include the following:
1. Eye symptoms: Night blindness and dry eye are typical manifestations of vitamin A deficiency. Patients experience decreased vision in low-light environments, and severe cases may lead to blindness. In addition, symptoms such as conjunctival dryness and corneal softening may also occur.
2. Skin symptoms: Dry, scaly, and itchy skin may occur, along with epithelial keratinization, follicular papules, and other symptoms.
3. Growth and development impairment: Vitamin A plays an important role in the growth and development of the skeletal system. Deficiency may lead to growth retardation and short stature.
4. Decreased immune function: Vitamin A helps regulate immune function. Its deficiency may lead to reduced immune capacity, increasing the risk of infections such as respiratory and gastrointestinal tract infections.
