Weight gain with chronic pancreatitis

I have been diagnosed with chronic pancreatitis. In the summer of 2023 I went through MRIs, CT scans and biopsies and this is my final diagnosis. I have calcifications in the pancreas head. I currently take.CREON with meals and I’m on a pain management regime and I’m doing well. Prior to my diagnosis I had lost a significant amount of weight. A year later with my treatments I find that I am gaining weight even though I eat extremely healthy two salads a day, low-fat dressing Dinner is usually grilled chicken breast with veggies, a turkey burger, or a pork chop with veggies. I limit all of my fats, have a high fiber diet and eat no red meat.I get close to 10,000 steps per day. Is it common to gain weight with this? Is it harder to lose weight? My annual bloodwork and physical is coming in January and I will certainly talk to my doctor about this. I would really like to keep my weight stable. I also might add that I am 54 and menopausal.
