Diarrhea• In Indonesia, diarrhea remains a major cause of death in
infant and children.• In the GIT, VAD is both cause and consequence of
diarrheal disease.• In 20th century, vitamin A was commonly known as the
anti-infective vitamin, when its deficiency was shown to be associated with various infections. However, the mechanism by which vitamin A protects the body against infection is unclear.

• A deficiency adversely affects the epithelial lining, leading to decreased mucous secretion and weakened local barriers to infection. Vitamin A deficiency may also lead to goblet cell depletion, abnormal villous architecture and villous atrophy, as well as adversely affecting humoral and cellular Immune functions
• Studies conducted in many countries have shown a benefit of vitamin A in treating diarrhea
