You can up your asacol to 12 pills a day. That will probably help if he is already seeing progress with the 6 pills a day. Also, rectal meds!! Again, I am sure you are both being really careful as to what he eats, and I am sure in his mind he is a little worried about
everything he puts in his mouth. The weight will come back, be patient. I tend to drink a lot of calories, juices I can handle and sparkling water, and ginger ale. But mostly fruit juices....all natural. Sometimes the carbonation in the ginger ale really kills me. Good luck and happy eating.
