[|AI|]  Hi, Thanks for writing to Chat Doctor. Food pipe becoming narrow at the lower end may be due to any reason either inside, outside the wall of the food pipe or withing the wall of the food pipe. So It's important to find out where is the lesion, to form a management protocol for your child. I feel an imaging study like CT or MRI is imperative, Thanks. If you have any more queries I am happy to answer them. Else, please rate this answer and close the discussion
