Define the terms hypervitaminosis and avitaminosis.
Hypervitaminosis is a disorder in which a person's body has too much vitamin A and vitamin D. This can occur if a person consumes too many vitamins or utilizes certain acne treatments for an extended length of time. Vision difficulties, skin abnormalities, and bone discomfort are all symptoms of hypervitaminosis and can cause liver damage and put a strain on the brain in long-term instances. Avitaminosis is a set of illnesses caused by a deficiency in one or more vitamins. It can happen if you have persistent severe diarrhoea or heavy sweating, or if you have elevated vitamin requirements during periods of fast growth, such as during infancy or pregnancy.
