Vomiting

Hi my name is Jaymee 23 years old. My brother 26 years old have a serious problem about his stomach flu and vomiting problem. Usually everyday he eat bread for breakfast but after that he feel his stomach pain and vomit all the food that he had today. My brother have this diseases since 2 years old. We see doctor many times. But it still not ok. I think he don't have enough nutrition. When he see food he will feel wants to vomit and his face look pale. Can you help me doctor? Because of this problem he cannot go to work or cannot even sleep well.

thanks

Would you please state your brother's weight (in kg or lbs) and height so I can evaluate his nutritional status? Is your brother on medication for his issue?
Thank you.
