Hello and Welcome to ‘Ask A Doctor’ service.
I have reviewed your query and here is my advice.
IBS is belly discomfort or pain and trouble with bowel habits:
diarrhea or
constipation or having a different kind of stool (thin, hard, or soft and liquid) or mix of above mentioned symptoms. Dietary changes are very important: Add fiber to your diet, say no to caffeine(coffee/soda), increase water intake, limit milk intake, eat small portions of the meal and carefully watch and make the lists of the food that may flare this condition so that a check is there for intake of these foods.
Medications may include: Bulking agents like
Psyllium, antibiotics like Rifaximin, for pain management, antispasmodics like Buspan, probiotics. If there is constipation, then
polyethylene glycol is a good option or Plecanatide. For diarrohea,
Loperamide can be taken. For pain relief, Buspan can be taken.
Please take care to consult the physician as the medications may vary, depending on your other health conditions.
Hope this helps. Wishing for your good health.
