For many of us, when we’re initially diagnosed with IBD or when we flare, we experience weight fluctuations. The number on the scale may plummet during times when eating anything hurts or seems to make symptoms worse. The number on the scale may skyrocket when we’re on prednisone and not only retaining fluid, but also wanting to eat everything in sight.
Andrew Jagim, PhD, CSCS*D, CISSN was diagnosed with ulcerative colitis in 2014 after being infected with an intestinal parasite (Giardia). He managed to remain in remission for a few years until things went downhill quickly at the end of 2016. He dropped 50 pounds over the course of 3-4 months, was going to the bathroom 15-plus times a day, was running constant fevers, severely fatigued, anemic, and had little appetite. In the spring of 2017, after two weeks on TPN and several days in the hospital, he decided that a sub-total colectomy was his best option at the time. Since then, Andrew’s battle has been a rollercoaster of ups and downs, resulting in 12 colorectal surgeries.

Sports and fitness have always been a huge part of Andrew’s life—so much so, that he made a career out of it. He has a doctorate in exercise physiology, is a certified strength & conditioning specialist and a certified sports nutritionist, so he has an extensive background when it comes to understanding the important roles of exercise and nutrition for health and performance.
“Throughout my life, a large part of my identity has always been tied to my physical appearance. I’ve always been known as someone who is athletic, big, and strong with a high state of fitness. I struggled immensely during my flares and surgery recoveries when I couldn’t work out, when I looked sick or couldn’t stop losing weight. It was like I was losing a sense of who I was and who I identified with. When I looked it the mirror, it pained me to see my hard-earned muscle just “falling off” when I was too sick or weak to workout. However, I have always been determined to rebuild my body and regain what I lost.”
This week on Lights, Camera, Crohn’s—a look at the impact disease flares and surgeries can have on body composition, and how you can try and counteract the changes through diet and exercise.
A cornerstone of the disease itself is a high state of inflammation – most of which is centralized to the gut; however, this can also have systemic effects thereby resulting in widespread joint pain, fatigue and even a state of anabolic resistance within muscle tissue. Essentially, this makes it challenging to maintain or increase muscle mass during a period of high disease activity. This can be coupled with a reduction in appetite which can exacerbate body weight loss and muscle loss.

Surgeries can range from minimally invasive procedures to treat a fistula to much larger and complex operations such as removal of sections of the bowel and placement of a stoma for an ostomy. Depending on the magnitude of the surgery, patients often must modify diet and physical activity based on the recommendations of the surgeon.
These modifications will likely lead to decrements in body weight, muscle, strength, and endurance in the short-term; especially individuals who may have been highly active prior to the surgery. However, in patients who may be extremely ill at the time of surgery, the procedure may help them regain lost weight and strength as their body may finally be able to heal and recover from the inflammatory cascade brought on by IBD.
The Case Study Andrew Conducted
A year and a half after Andrew’s colectomy, he decided to schedule the second step for the J-pouch procedure. However, prior to, he decided to take advantage of this unique opportunity and conduct a case study on himself to document the changes in body composition and performance throughout the recovery process. He was curious how a surgery like that would impact someone with his fitness state as most of the literature focused on smaller or more sedentary individuals. Leading up to surgery, he had been able to resume his regular fitness routine and got his weight close to where it had been for most of his adult life.
“As seen in the figure below from my published case study, there were significant declines in body weight (-10.5%), lean body mass (-9.9%) and endurance (-40.3%) 4-weeks post-surgery. At 16 weeks postoperatively, most parameters were near their baseline levels (within 1–7%), with the exception of my peak endurance, which was still 20.4% below baseline. Thankfully, I was able to leverage my educational background and expertise in exercise physiology and nutrition to use targeted exercise and nutritional strategies to retrain my body and build my physique back up,” explained Andrew.

The balancing act of trial and error
As many IBD patients know, there are a lot of nuances, misconceptions, and unknowns regarding how diet impacts disease. For Andrew, it has been a lot trial and error to find foods that worked for him and helped him achieve his goals.
“Early in the recovery stage, just getting my appetite back and trying to eat more while not interfering with any post-operative dietary recommendations was always my goal. For me, this meant trying to eat about 2,500 – 2,750 calories and 150-170 grams of protein per day. In my opinion, these are the two most important dietary goals when it comes to regaining any weight (especially muscle mass) following surgery or during a flare. It will also help support the tissue and incision recovery following surgery”
Regarding exercise, strength training, is the most effective form of exercise to regain lean body mass following surgery. However, most colorectal surgeons (for good reasons) impose a lifting restriction of no more than ~10-15 lbs. for about 6 weeks following surgery to allow the incisions to heal and avoid the risk of hernia.
“For my larger surgeries, this was easy to abide by as I was in so much pain and was so fatigued that it was a struggle to just get dressed and ready for the day, so there was no temptation to get back in the weight room any time soon. But for the smaller surgeries, as I got closer to the 6-week mark, I was anxious to get back to my old routine. I took a very conservative approach and used a lot of alternative training techniques (i.e. blood flow restriction training, isometrics, resistance bands, etc.) to elicit an adequate training stimulus while not having to lift heavy weights and to avoid injury,” said Andrew.

Andrew’s main piece of advice about life with IBD? “Be prepared for a rollercoaster of changes to both your body composition and physical abilities throughout battles with IBD – especially during a flare or following surgery. Unfortunately this also will likely take a toll on your mental health as well, or at least it certainly did for me. However, just know that you can always get it back in time and more often than not, come back even stronger. Be patient and give your body rest when needed but otherwise keep grinding.”
Everyone has their own battles they are fighting
“I think my experience with IBD has taught me that everyone has their own battles they are fighting – even if they don’t show it. Additionally, it is also a reminder that not all disabilities are visible as a lot of people are probably unaware that I live with a permanent ostomy. I have chosen to keep a lot of my health struggles private and I think a lot of people will be surprised when they hear what I’ve endured over the past five years as I have still managed to have a successful career and not miss much work – despite all the surgeries and time spent feeling very ill.”
Andrew’s IBD journey also shifted his research focus a bit and challenged him to apply my knowledge of how to increase performance, strength and muscle mass in athletes towards a more clinical application.
“A lot of the strategies that work well with athletes can be modified and used in clinical settings as several of the benefits (i.e. increased muscle, strength, endurance, energy, etc.) may also help improve quality of life in patients will a chronic illness, those who are critically ill, or those recovering from surgery. It’s just a matter of making the appropriate modifications and fitting them to the current need,” said Andrew.
