Hi.
Thanks for your query.
Noted the history of water
diarrhea since yesterday afternoon, feeling gassy, abdominal flipping, took 4 Imodium, stopped diarrhea but other symptoms remain so, green colored stool the now, passing of bright red blood, took pepto, took Gatorade, .
This is something severe and may not pass off.
Hence I would advise you the following:
Get a consultation of a Doctor for clinical evaluation, examination.
Tests of blood, stool and urine.
A course of an antibiotic,
metronidazole, probiotics.
Activated
charcoal tablets and multivitamins.
Injectable antibiotics if required.
Continue taking
soft diet, Gatorade.
