I'm not sure how to go about finding out info on how to relieve constipation. My husband is one yr. out and still uses PEG (6 bottles of BOOST PLUS daily) while eating by mouth once a day (less than 1/2 c. of food) and finds constipation is a big problem. He is taking Benefiber twice a day but still has the problem. May be due to the Dilaudid he takes for chronic pain in jaw (exposed jawbone since extraction of teeth and radiation/lack of healing)./And a second problem--pain due to exposed jawbone. Site where teeth were extracted hasn't healed after 2 surgeries and hyperbaric treatments. Help with either of these problems is welcome!
