Reasons for peeling around fingernails

Fingernails play a very important role for us. Fingernails protect our fingers. Once our fingernails show abnormalities of one kind or another, we must pay attention to it. Sometimes we will have symptoms of peeling around the fingernails. We generally ignore such symptoms. In fact, this approach is wrong. Peeling around the fingernails is because our body lacks vitamin C.

Peeling around the fingernails is a sign of vitamin C deficiency. Vitamin C is a strong reducing agent that is reversibly oxidized and reduced in the body, thus playing a redox role in cells. It is involved in the metabolism of phenylalanine and tyrosine. As a reducing agent (along with oxygen, ferrous ions and 2-keto acids) vitamin C activates enzymes that hydroxylate procollagen proline and lysine to procollagen hydroxyproline and hydroxylysine. Animals with scurvy become increasingly deficient in the amino acid hydroxyproline in elastin. Vitamin C protects folate reductase, the enzyme that converts folic acid to folinic acid, and helps release free folate from folic acid complexes in food. Vitamin C promotes the absorption of iron. Severe deficiency can cause scurvy, an acute or chronic disease characterized by bleeding and abnormal osteoid and dentin formation. In the northern pastoral areas where there is a shortage of vegetables and fruits, or in cities and rural areas where bottle-fed infants neglect to provide complementary foods, especially in remote rural areas, children still become ill due to improper feeding.

Cause: Lack of vitamin C.

1. Insufficient intake. If the mother has adequate nutrition, the child will have appropriate vitamin C reserves at birth. The vitamin C content in umbilical cord blood plasma is 2 to 4 times higher than that in maternal plasma, so infants under 3 months old are less likely to develop the disease. However, if the pregnant mother's diet lacks vitamin C, the newborn may also suffer from scurvy. Normal human milk contains about 40-70 mg/L (4-7 mg/dl) of vitamin C, which can meet the needs of general infants.

2. The need to increase When the metabolic rate increases, the need for vitamin C increases. During active growth, the vitamin C content of body tissues drops sharply. Premature infants grow and develop faster, and their vitamin C requirements are relatively greater than normal infants, so they should be supplemented with more.

3. Other factors, such as long-term intake of large amounts of vitamin C, increase its catabolism and renal excretion, thereby reducing plasma vitamin C concentrations. If you suddenly stop taking large amounts of vitamin C, scurvy may occur. If large amounts of vitamin C are used for a long time during pregnancy, the newborn may still suffer from scurvy even if he or she consumes normal amounts of vitamin C every day after birth.

In the above article, we introduced the importance of fingernails. We must protect our fingernails in our daily lives. The above article analyzes in detail the reasons for peeling around the fingernails. I hope the information introduced above is useful to everyone.
