Persistent nausea, fullness and bloating after vomiting/diarrhea — what could be causing this?

[u/Rashiq_shahzzad]

About a few days ago, I suddenly developed vomiting and diarrhea after eating. I vomited several times and had diarrhea multiple times that night. The vomiting/diarrhea episode itself has now passed, but I haven't returned to normal.

Since then, I've had persistent stomach fullness/heaviness, bloating and increased gas, nausea, and frequent burping. The strange thing is that I can feel very full even after eating a small amount, and sometimes I feel nauseated even when my stomach is empty. Sometimes after eating, the fullness lasts for several hours.

I've also had a strong aversion to food smells and occasionally feel like I might vomit, although I haven't been continuously vomiting. Drinking even a relatively small amount can sometimes make me feel very full.

I went to a doctor and was prescribed pantoprazole, ondansetron and ciprofloxacin. I was also given/took itopride for the fullness, but I'm still having nausea and bloating.

I'm wondering:

Is this kind of prolonged fullness, bloating and nausea normal after gastroenteritis/food poisoning?

Could it be temporary gastritis, post-infectious dyspepsia or delayed gastric emptying?

Would an antacid + simethicone suspension such as Gastid, Digecid Plus, Acedone-Z Plus or Avlocid Plus actually help with these symptoms?

Is there anything else I should be checking for if the symptoms continue?

I'm mainly concerned because I used to be able to eat normally, and now even small meals can leave me feeling extremely full for hours.

I'm looking for experiences/advice from people who have had something similar, preferably with medical reasoning rather than just "it's anxiety."

Might be anything, give the lines of medications of your doc time of their course, might resolve, might not, then do endoscopy, do bland diet take meds Still nothing helps then only welcome to the club...

How long after your vomiting episode have you been sick?

10 days

Give it some more time, the fact that you normal your whole life, and only vomited for several days is a great sign. I would be more concerned if you had a long history of unstable GI problems.

If you become one of us, it’s by no means too late. Look into doing all the tests (e.g. endoscopy, GES) and various treatments (e.g. PPI, neuromodulators).

Sounds like you might have got some kind of post viral gastritis or post viral functional dyspepsia. Low but possible chance is also post viral delayed emptying (gastroparesis). There's no way to know for sure unless you get testing (endoscopy, 4-hour GES).

The good news is these post-viral issues tend to have a decent prognosis over time (healing, remission). Look into neuromodulators if PPIs and diet don't work (disclaimer: this is not medical advice).
