What Causes A Vitamin A Deficiency?

Liver Disorders

Liver disorders can also be a cause of a deficiency in vitamin A. The liver is a part of the digestive system that metabolizes micronutrients and macronutrients. When the liver doesn’t function properly, it makes it difficult for the body to absorb vitamin A. The liver uses vitamin A to help promote healthy cell function. When it doesn’t function well, the lack of vitamin A can change the way the liver functions, creating a cyclical issue. Vitamin A and iron deficiencies are some of the most common deficiencies around the world. The liver is the main site of vitamin A storage, and when it malfunctions, it can send too much vitamin A to other tissues. This can be a particular problem when the patient has consumed too much alcohol and has damaged their liver. However, too much vitamin A can be toxic to the organ, causing it to form scar tissue.
