7. Bloating
While bloating will often result from over-eating or as a result of a woman’s normal and expected monthly cycle, those causes should be relatively easy to separate from other instances where bloating is something that should be further investigated. Unexpected and persistent bloating can also result from irritable bowel syndrome (IBS) or gastroesophageal reflux disease (GERD) and less commonly, celiac disease or even ovarian cancer.
