Q: I am a mother of a 3-year-old boy who has been identified as ADHD child. He is undergoing treatment for that. He has a tendency of getting cold and fever often. He is 2 feet and 8 inches tall and weighs 12 kg. He is not able to eat due to his regular illness. He is not at all interested in taking any kind of food. Are there any medicines that can develop his immunity and improve his appetite?

A:There is no medicine, which can be prescribed to enhance the immunity and improve appetite without resulting in significant side effects. Perhaps the child is taking as much as is needed, and recurrent colds may be allergic in origin. Once the ADHD improves, the feeding may improve.
