Thanks for writing your query.
After reading your post it seems that your symptoms can be due to antibiotic induced loose motion
Antibiotics usually disturb the normal bacterial flora present in small intestine
resulting in loose motion. These useful bacteria help in the process of digestion and absorption.
I would advise that you should take a probiotic
daily for relief from your symptoms.
if your symptoms persists, get yourself clinically examined and investigated by your doctor.
I hope this is helpful to you.
