Hi,
Your history of feeling gassy, diarrhea and
indigestion is suggestive of an intestinal infection.
The dark urine can be due to
dehydration but redness can suggest of a possible of a stone in urinary tract or infection.
Hence I would advise you the following:
Consult your Doctor for clinical evaluation.
Tests of urine, stool and blood will help more.
A course of an antibiotic active against intestinal as well as
Urinary tract infection such as Ofloxacin and
metronidazole may solve your problem. These are prescription based medicines hence you need a valid prescription of a Doctor.
Take plenty of oral fluids.
Take a PPI like
Omeprazole.
Prebiotics and probiotics help to restore the intestinal bacterial normal flora.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. T Chandrakant,
General Surgeon
