Hi.
Thanks for your query.
Noted the history of morning time not feeling good,
severe nausea and retching after passing bowel movement, feels better after lunch at 10:30 am, Doctor said to wait and see...
This is atypical presentation and can be due to
gastritis in the morning as there is increase in acid production causing nausea and retching and any other such related complains.
I would advise you the following in such a situation:
Get an upper GI Endoscopy.
Ultrasonography of the whole abdomen.
Get started on a PPI like
Omeprazole, antacid at every three hours,
Domperidone at 6 am.
See the results, if there is no response, consult a Specialist for a clinical evaluation, examination and further management,
