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. Cancers of the gut and in female ovarian cancer and PCOD too could be a cause—not meant to scare you but if all other causes are ruled out, then this can be a possibility.
