Hello, thanks for the query.
Coming to the direct point I would like to say that colonoscopy
will not yield any thing i. e your's intestines are normal bot small and large.
Endoscopy will not give any thing.
Still you have problem that difficult to tolerate the smell of food and meat.
In my opinion all these problems are psychogenic so please consult a psychiatrist
and he will solve your problem within a short period.
Good luck for speedy recovery. Dr. HET
