Vitamin A is responsible for the body’s health, and a large deficit can favor the appearance of diseases.
Among the most common signs of a lack of this vitamin are visual disturbances, chest infections, difficulty conceiving, dry or inflamed skin.
Foods contain two forms of vitamin A performed and provitamin. Preformed vitamin a, also called retinol, is found in meat, fish, eggs and dairy products. Provitamin A contains carotenoids, plant pigments that the body converts into vitamin A in the gut. The main provitamin A carotenoids are beta-carotene, alpha-carotene and beta-cryptoxanthin, potrivit National Institutes of Healthquoted from medicool.ro.
Especially pregnant women, nursing mothers, infants and children can be deficient in vitamin A. Also, cystic fibrosis and chronic diarrhea can increase the risk of developing a deficiency.
Here are the main signs of vitamin A deficiency:
Dry eyes
In severe cases, vitamin A deficiency can cause complete blindness or corneal death, both of which are characterized by Bitot spots. Dry eyes are one of the first signs of deficiency. Vitamin A supplementation may improve this condition.
Dry skin
Vitamin A has an important role for the formation and regeneration of skin cells. It helps fight inflammation caused by certain skin conditions. Alitretinoin, a prescription medicine, can be effective in treating eczema. Vitamin A deficiency can be among the main factors that can cause eczema.
Acne and rashes
Vitamin A can prevent and treat acne, in topical and oral form, conform Healthline. Creams containing vitamin A significantly reduce acne lesions. But they also have adverse effects.
Neck and chest infections
Frequent throat or chest infections can be a sign of vitamin A deficiency. Vitamin A supplements can help treat respiratory tract infections. But taking vitamin A supplements in excess increases the risk of contracting throat and chest infections.
Problems in wound healing
Wounds or surgeries that don’t heal well can be associated with low levels of vitamin A. This supports the creation of collagen. Both in oral and topical form it can strengthen the skin. It can also improve collagen production, and treating the skin with topical vitamin A can prevent diabetes-related wounds.
Night blindness
Severe vitamin A deficiency can cause night blindness. Getting vitamin A through diet and supplements can have beneficial effects on eye health.
Infertility
Vitamin A has a significant role in ensuring reproductive functions in both men and women. At the same time, it supports the development of babies. Infertile men may have a greater need for antioxidants due to increased levels of oxidative stress in the body. Vitamin A is one of the nutrients that act as an antioxidant. But it should be administered with caution by people who want to have children because there is a greater risk of passing on genetic deficiencies.
