Bitter truth
Today a 14 year old went to eat burger, drank yellow sauce by mistake instead of water and burnt his mouth. I examined him there was a chemical burn in his mouth and his soft palate was swollen. His endoscopy revealed gastric erosions. This child may develop gastric outlet block and may need surgery.
I am still stunned, our children are consuming such strong chemicals. 
Avoid junk food as much as you can !
