The Joys of Runner's Colitis

Last month I wrote an article titled, “When You Know Better But Still Do It Anyway.” 

Since that time, I have been to the GI doctor and started implementing some of the guidelines he gave me to follow. I also would like to share some of the great advice and insight he gave that he shared with me on the gut-brain connection and gut microbiome.  

Let me start by saying the irony was thick as this GI doctor was one of my top referring doctors when I did outpatient nutrition education and counseling.  To become one of his patients was a full-circle kind of situation. I explained my situation, symptoms, and various activities I participate in. What I was expecting was for him to make me start an elimination diet, but instead he listened to me and told me not to do anything yet. 

Because I am a runner and currently training for a marathon, as well as all the symptoms I was describing, he came at me with the diagnosis of Runner's Colitis. 

Also known as Ischemic Colitis, this presents as an inflammation in the large intestine due to a lack of blood flow to the area, which is typically due to a lack of oxygen to the area either through blocked or narrowed arteries. Although more common in people over the age of 60, this can also occur not only in long distance runners, but it is also increased in individuals who take certain medications such as estrogen, pseudoephedrine (a decongestant), and certain heart and migraine medications.

I, of course, had to investigate this on my own to understand exactly what this diagnosis was. Throughout my running endeavors I have experienced one, if not all the symptoms at some point, multiple times. Symptoms include nausea (check), diarrhea (unfortunately, yes), a feeling of urgency to “move your bowels” (I like to just say poop), bright red or maroon blood in your stool (this has brought on feelings of terror and concern). Lastly, the pain, cramping, and tenderness in the abdomen that slowly occurs or sometimes happens suddenly without warning (OUCH, and it is pretty terrible). 

The Doctor and I had a great conversation about what I should be doing at this point. I told him I already know my trigger foods and they ironically are all low FODMAP, so following that diet would be pointless for me. (Please note I am a huge fan of this diet for those that can really benefit from it, I have seen it work miracles for people.) He did not want me to eliminate gluten at this point either, but it is not off the table. He really wants me to wait until after my marathon before I make any big changes. 

I found this interesting. He explained that often we have a lot more anxiety tied up in our GI tract than I realized. 

Did you know there are more serotonin receptors in our GI tracts than there are in the brain? 95% of the serotonin produced in your body comes from the gut. Targeting these receptors can help with treating IBS, and other GI disorders (Clin. Chim. Acta., 2009). Because of this, the pressure of performing well throughout my training and especially at my race, can have a direct impact on how my gut responds to the heavy exercise I am doing. 

Another big thing I was told to focus on is hydration. It is very hot and humid where I live, and many of my training runs are out in the elements (temps higher than 85 degrees, with humidity being above 90%). I have been mindful of drinking more water throughout the day (dehydration is thought to play a role in ischemic colitis for runners), 120-160 ounces, as well as staging isotonic hydration (Body Armor, Gatorade, etc) throughout the course of my longer runs. I stay away from foods that I know are triggers, I will be abstaining from alcohol until after my race, and I bought the best device ever, a squatty potty. 

Once I have completed my marathon and have recovered, I have another follow-up appointment with my doctor. This will be the point where we determine if it’s worth cutting gluten for a couple weeks or if I need to get a colonoscopy. Either way I’ll probably tell you all about my experience, so stay tuned!
