Thanks for writing your query.
After reading your post, I would like to advise that you should get your stool examined for any infection or worm infestation.
You can take a probiotic
once a day, as some antibiotics disturb the normal useful bacterial flora present in the intestines. These bacteria help in the process of digestion and absorption. A probiotic helps to restore the useful bacterial flora in the intestines.(It will be more helpful if you mention the names of the medicines you are taking).
You can do deworming by taking Albendazole
400 mg at night, if stool reports indicate worm infestation.
You should eat light meals prepared under hygienic conditions.
Also maintain your hydration.
I hope this is helpful to you.
