If the bloating is due to antibiotics, it will settle down. If not, change your
OCP and see. If still you do not benefit, then other causes will need to be looked at.
Other than IBS or spastic colon you could be suffering from Celiac Disease/Ulcerative Colitis/ Crohn’s disease, H pylori infection, diabetes, food intolerance, malabsorption syndromes, constipation, gallbladder and liver problems, pancreatic dysfunction, or taking a diet rich in sulfites.
