If no other problem,you won't get IBS
I have gone through your query carefully and feel sorry for the situation you are in.
I suggest to:
- drink plenty of water
- take tasectan and probiotics to stop diarrhea
and improve intestinal function
- be careful with your diet, try to have light meals (yogurt, curd, soups)
Once the toxins will be eliminated from your body, the intestinal symptoms will be reversed. You won't get irritable bowel syndrome
for the rest of your life. Unless other problems with your GI tract will be diagnosed.
Hope it was of help!
