Vitamin A deficiency: Itchy skin could signal serious deficiency – may lead to blindness

Keratinisation – This is a process by which cells become filled with keratin protein, die, and form tough, resistant structures in the urinary, gastrointestinal and respiratory tracts.

Stunted growth – Not having enough vitamin A could delay growth or cause children to experience slow bone growth or stunted growth.

Fertility issues – A deficiency in vitamin A may cause challenges when trying to conceive a child, and in some cases, infertility.

People most at risk of a vitamin A deficiency are those with diseases of the gastrointestinal system that interfere with absorption of vitamin A, such as celiac disease, cirrhosis, pancreatic insufficiency and bile duct disorder.
