Constipation Issues
How much exercise are you doing? My NUT told me that exercise and drinking the water helps keep things "moving". I have noticed this true because when having gall bladder attacks I hurt to much to exercise and became constipated asa soon as gall stone gone and started exercising again things got better. You may also try taking some Fiber and see if that helps.
Angie, To answer your question...from my experience and talking to others constipation is a very common issue with wls. I'm just under 5 weeks out and my BM's have gotten better but all the protein you will be eating causes most of the issues. Getting enough water and exercising will help but it's not unusual to go a few days without a BM even then that's when you pull out the Benefiber, eat some oatmeal or something else with fiber or whatever works for you. The olive oil tip sounds promising. Although it's not my favorite thing to experience it really has been, at least for me, a minor complicaton.
