###Human: Is pneumonia causing weight loss in my child? ###Assistant: Hi. The weight is quite less for an approximately 12 months old child. Please start the child on Multivitamins like Calcimax P 5 ml twice a day and syrup Visyneral Z 5 ml once a day each for three months. Also, start the child on complementary feeds if not yet started. Get the child physically evaluated and probably basic blood tests have to be done to find out if currently there is any infection because of which she is loosing weight.
