Are you getting enough calories? If your digestive tract is functioning better, you should be gaining weight. My son was eating very much after he started his Remicade and put on much needed weight. Once he was at a good weight, his eating slowed down and he is eating normally and maintaining his optimum weight as he is absorbing the nutrients properly. Are you hungry? Do you have a good appetite and how are you eating? Have you had any blood tests to see if everything checks out? You might need an adjustment to your dosage.
