Constipation is a very common medical problem, and serious constipation can definitely cause pelvic and abdominal pain
. It does this because the feces that are not passed begin to accumulate and to stretch out the large intestine, causing pain. So it is possible that the new onset of pain is just the effect of worsening constipation that needs to be more aggressively treated. Most cases of constipation cannot be managed just with fiber and often require other laxative or stimulant medications. It is also important to determine if the constipation is a new symptom. For example, if your wife was never constipated prior to this last year, then it is more likely that a hormone imbalance, like hypothyroidism, is causing the new symptoms and this is less likely if it is a life long complaint. Regardless, your wife should get a thorough medical examination by her primary care doctor
and likely some blood work to rule out other causes of constipation. In addition to hypothyroidism, long standing lactose intolerance can cause constipation. Also, celiac disease (an intolerance to the gluten protein in wheat and similar grains) can also cause constipation. Finally, irritable bowel syndrome, characterized by pain, cramping and either constipation or diarrhea
is often brought out in times of stress.
