What could be the cause of constipation and nausea?

Answer 1

These symptoms apply to a myriad of conditions, most mild, some critical. You'll have to decide when it's serious enough to call for medical help. That said, there are lots of non-critical conditions that can be treated or wioll resolve themselves without requiring a doctor. The first places I'd look for an answer are: * Medication. Are you taking pain meds, particularly opiates or opioids? These produce both of those symptoms. If so, talk to your doc about a mild laxative and perhaps an anti-emetic. * Diet. Have you changed your diet? Consider adding in fruits, and possibly an over-the-counter laxative in mild dosages. * Dehydration. Buy a sports drink (not the Energy! drinks -- the rehydrating ones) and see if this helps. If this persists for more than 2-3 days, or gets worse (e.g. progresses to vomiting for one), see a doc.
