The 8 Symptoms of Vitamin A Deficiency that everyone needs to know. In addition, Vitamin A is important for many bodily functions as it is a fat soluble vitamin important for having a proper vision, a strong immune system, reproduction and good health of the skin.
In addition, it is possible to find in foods two types of vitamin A: preformed vitamin A and provitamin A.
Also known as retinol, preformed vitamin A is commonly found in meat, fish, eggs and dairy products.
However, the body converts carotenoids into plant foods, such as red, green, yellow, and orange fruits and vegetables, in vitamin A.
Although deficiency is rare in developed countries, many people in developing countries do not receive vitamin A.
Those most at risk of disability are pregnant women, nursing mothers, infants and children. Conditions such as cystic fibrosis and chronic diarrhea may also increase the risk of disability. However, check out the following The 8 Symptoms of Vitamin A Deficiency:
1. Throat and Chest Infections:
One of the symptoms of Vitamin A deficiency can be frequent infections, especially in the throat or chest.
Vitamin A supplementation may help with respiratory tract infections, but the results of the research are mixed.
A study in children in Ecuador showed that underweight children who took 10,000 IU of vitamin A per week had fewer respiratory infections than those who received placebo.
However, a review of studies in children found that vitamin A supplements may increase the risk of developing throat and chest infections by 8%.
The authors suggested that supplements should only be given to those with real disabilities.
In addition, according to a study in the elderly, the high blood levels of carotenoid beta-carotene provitamin A may protect against respiratory infections.
2. Acne and Fungi:
Because vitamin A promotes skin development and fights inflammation, it can help prevent or treat acne . Several studies have associated low vitamin A levels with the presence of acne .
In a study of 200 adults, vitamin A levels in those with acne were more than 80 mcg lower than those without the condition.
Topical and oral vitamin A can treat acne . Research shows that creams containing vitamin A can reduce the number of acne lesions by 50%.
The best known form of oral vitamin A used to treat acne is isotretinoin, or Accutane. This medication can be very effective in treating acne , but it can have several side effects, including mood swings and birth defects.
3. Dry Skin:
As vitamin A is important for the creation and repair of skin cells. It also helps fight inflammation caused by skin problems.
Not receiving the proper amount of vitamin A can cause the development of eczema and other skin problems.
Eczema is a condition that causes dry skin, itching and inflammation. Several clinical studies have shown that alitretinoin, a prescription drug with vitamin A activity, is effective in treating eczema.
In a 12-week study, people with chronic eczema who took 10 to 40 mg of alitretinoin per day had a reduction of up to 53% in symptoms. Keep in mind that dry skin can have many causes, but chronic vitamin A deficiency may be the reason.
4. Healing of Poor Injuries:
Wounds that do not heal well after injury or surgery may be linked to low levels of vitamin A.
This is because vitamin A promotes the creation of collagen, an important component of healthy skin. Research suggests that both oral and topical vitamin A can strengthen the skin.
A study in rats found that oral vitamin A improved collagen production. The vitamin had this effect, although the rats were taking steroids, which may inhibit wound healing.
Additional research on mice found that treatment of skin with topical vitamin A seemed to prevent wounds associated with diabetes .
Research on humans shows similar results. Elderly men who treated wounds with topical vitamin A had a 50% reduction in the size of their wounds compared to those who did not use the cream.
5. Night Blindness:
Severe vitamin A deficiency can lead to night blindness . Several observational studies have reported a high prevalence of night blindness in developing nations.
Due to the extent of this problem, health professionals worked to improve vitamin A levels in people at risk of night blindness .
In one study, women with nocturnal blindness received vitamin A in the form of food or supplements. Both forms of vitamin A improved the condition. Women’s ability to adapt to darkness increased by more than 50% in six weeks of treatment.
6. Atrophic Growth:
Children who do not consume enough vitamin A may show stunted growth. This is because vitamin A is necessary for the proper development of the human body.
Several studies have shown that vitamin A supplements, alone or with other nutrients, can enhance growth. Most of these studies were performed in children from developing countries.
In fact, a study of more than 1,000 children in Indonesia found that those with Vitamin A deficiency who took high doses of supplements for four months grew 0.39 cm more than children taking placebo.
However, a review of studies found that supplementation with vitamin A in combination with other nutrients may have a greater impact on growth than vitamin A supplementation alone.
For example, atrophied growth children in South Africa who received multiple vitamins and minerals had a better age-length than those who received only vitamin A.
7. Infertility and Difficulty to Conceive:
Vitamin A is required for reproduction in both men and women, as well as proper development in babies.
If you are having trouble getting pregnant, undeniably this deficiency may be one of the reasons. A deficiency of Vitamin A can lead to infertility in men and women.
Studies show that rats with Vitamin A deficiency have difficulty becoming pregnant and may have embryos with congenital defects.
Other research suggests that infertile men may have a greater need for antioxidants because of higher levels of oxidative stress in their bodies. Vitamin A is one of the nutrients that acts as an antioxidant in the body.
Vitamin A deficiency is also related to miscarriages.
However, a study that looked at blood levels of different nutrients in women who had recurrent miscarriages found that they had low levels of vitamin A.
8. Dry Eyes:
Certain eye problems are some of the most known problems related to Vitamin A Deficiency .
In extreme cases, not getting sufficient vitamin A can lead to complete blindness or death of the corneas, which are characterized by marks called Bitot stains.
Dry eyes, or the inability to produce tears, are one of the first signs of Vitamin A Deficiency .
Young children in India, Africa and Southeast Asia who have diets without vitamin A are at greater risk of developing dry eyes. Supplementing with vitamin A may improve this condition.
One study found that high doses of vitamin A decreased the prevalence of dry eyes by 63% among infants and children who took supplements for 16 months.
Excess Vitamin A:
Vitamin A is valuable for overall health. However, much of this can be dangerous.
Hypervitaminosis A, or vitamin A toxicity, usually results from the use of high doses of supplements for long periods of time. People rarely take too much vitamin A from diet alone.
Excess vitamin A is stored in the liver and can lead to toxicity and troublesome symptoms such as changes in vision, bone swelling, dry and rough skin, mouth ulcers and confusion.
Pregnant women should be especially careful not to consume too much vitamin A to avoid possible birth defects.
First check with your doctor before starting vitamin A supplements.
People with certain health conditions may need a greater amount of vitamin A. However, most healthy adults need 700 to 900 mcg per day. Women who are breastfeeding need more, while children need less.
Vitamin A deficiency is prevalent in developing nations, but it is rare in America and other developed countries.
In addition, little vitamin A can cause skin inflammation, night blindness , infertility, growth retardation, and respiratory infections.
Therefore, people with sores and acne may have lower blood levels of vitamin A and benefit from treatment with higher doses of the vitamin.
Vitamin A is found in meat, dairy and eggs, as well as in red, orange, yellow, and green plant foods. To make sure you get enough vitamin A, eat a variety of these foods.
If you suspect you have a Vitamin A Deficiency , talk to your doctor or health care professional. Certainly by eating a variety of these foods and supplements, fixing a deficiency can be simple.
