Introduction
Pale corners of the mouth may be caused by a deficiency in vitamin B2, as well as deficiencies in vitamin B5 or B12. In addition, pale mouth corners can also result from a lack of vitamin B6. It is recommended to seek timely medical examination at a hospital to determine the underlying cause and receive targeted treatment. In daily life, one should consume more fresh fruits and vegetables, and avoid spicy, irritating, greasy, and high-sugar foods.
White discoloration at the corners of the mouth may be due to vitamin B2 deficiency, and could also be related to deficiencies in vitamin B5 or vitamin B12. Specific analyses are as follows:
1. Vitamin B2 deficiency
Vitamin B2, also known as riboflavin, is a water-soluble vitamin that helps maintain the health of skin and hair follicles, and promotes cellular growth and metabolism. When the body lacks vitamin B2, it may lead to mouth sores and oral ulcers. Therefore, timely supplementation of vitamin B2 is necessary to maintain healthy skin and hair follicles. Treatment can include taking vitamin B2 tablets under medical supervision.
2. Vitamin B5 deficiency
Vitamin B5 is a substance involved in antibody production and plays an important role in maintaining the health of hair, skin, and blood. A deficiency in vitamin B5 may cause symptoms such as fatigue, headaches, nausea, and vomiting, which may subsequently lead to white discoloration at the corners of the mouth. Treatment may involve taking vitamin B5 supplements under a doctor's guidance.
3. Vitamin B12 deficiency
Vitamin B12 is the only vitamin in the human body that contains a metal element—specifically cobalt, also known as cyanocobalamin. A deficiency in vitamin B12 can result in iron-deficiency anemia, which may manifest as pale corners of the mouth. In such cases, vitamin B12 tablets can be taken under medical supervision.
In addition, white discoloration at the corners of the mouth may also result from vitamin B6 deficiency. It is recommended to seek timely medical evaluation to determine the underlying cause and receive appropriate treatment. In daily life, one should consume more fresh fruits and vegetables, and avoid spicy, irritating, greasy, and high-sugar foods.
