Vitamin A is also involved in supporting other organs like the lungs, kidneys and even the function of the heart. Here are four signs and symptoms that often occur in the body of vitamin A.
1. Vision loss
Vitamin A is essential in the synthesis of a substance called Rhodopsin (pigment in the retina). Rhodopsin facilitates the natural adaptation of the eyes to dim light, and if deficient in vitamin A you will begin experiencing a hard look at night.
Vitamin A deficiency can lead to dry eyes, due to changes in the shape of the eye causing the cornea to dry, wrinkled. Dry eye also affects the secretion of the gut so the body can not moisturize the eyes, as well as remove bacteria or any foreign object in the eye. Dry eye can not be resolved in time, leading to blindness.
2. Skin problems
One of the most common signs of vitamin A deficiency is the change in skin texture. Vitamin A deficiency can lead to dry skin, dry skin and scaly skin.
Vitamin A deficiency can also cause phrynoderma, with acne manifestations in various areas of the body such as the arms, thighs, back, shoulders, abdomen and even the buttocks. Phrynoderma disease is caused by obstruction of the sweat gland.
3. Respiratory problems
Vitamin A deficiency is also closely related to respiratory problems. It makes the lining of the nose, throat, bronchi, and windpipe dry and rough, making the respiratory system more susceptible to infection.
4. The problem of reproductive system (female)
Vitamin A deficiency can also cause problems in female reproductive organs. The most common signs include vaginitis, keratoconus in the pelvis, fallopian tubes, bladder, uterus and other parts of the genital tract. Failure to address these problems quickly can lead to infertility.
