If anorexia is not treated promptly, children can suffer from mild to severe malnutrition. Their resistance will also be reduced, leading to increased susceptibility to disease, slow weight gain, and even more anorexia.

Anorexia is one of the most common eating disorders, this condition is common in children aged 1-6. Anorexia means that children refuse to eat/eat little, children cry and find ways to disturb when they see food or often keep food in their mouth for a long time, some children with anorexia only breastfeed. "Why do children have anorexia?", "What to do when children with anorexia gain weight slowly?" are questions that many parents are concerned about today.
