So happy to know that they are finally finding something out to help your hubby...that is half the battle, as you already know. The weight gain is a wonderful thing. Funny how just a few pounds can help to set the mind at ease, since it is such a good sign.
Harry, my DH, is now being treated for Gastro Parisis and seems to be responding well to treatment. He too has gained 4 lbs!! If he continues to respond well to treatment I believe the next step is to get him off the medication and have a pacemaker inserted into his stomach to keep things moving, since the meds can do irreversible damage neurologically.
I will continue to pray for you and your husband. I know the struggles one can face with issues with the colon. I have Ulcerative Colitis and my DH's sister has Crohn's Disease, so totally understand how it can effect many aspects of health and lifestyle. Sounds like they are on the right road to getting him fixed up....God is good!!
Take care of each other and thanks for the update. Keep us posted!!
