Beware: This Type Of Workout Could Be Making You Constipated

When searching for the cause of your digestive issues, your exercise routine may not be the first place you look. We typically see exercise as something that can only help us—unless, of course, it’s done improperly or way too often—but in reality, certain kinds of exercise can shock the body and its internal processes, which can lead to some serious blockage.

Now, everyone’s gut is different, but as someone who has struggled with her stomach, my guess is that you’re open to anything that will get you closer to an answer (especially an expert opinion). So take your sneakers off and stay awhile—this news may or may not unsettle you.

The debate surrounding exercise and constipation.

Depending on who you speak to, you may hear different answers about whether or not working out can make you constipated. I’ve always landed somewhere in the middle—believing that if a workout was super sweaty, it could dehydrate me (causing constipation), or it would get the contents of my stomach moving, which would help digestion.

The jury is (somewhat) out—mainly because there are so many types of exercise and levels of intensity that there's no way to say that all exercise will or won't cause constipation. It also depends on the person. But most experts agree that consistently doing this one type of workout can cause tummy troubles. That workout, my friends, is our beloved HIIT.

Why HIIT can cause constipation.

HIIT, or high intensity interval training, has a lot going for it. It requires very little space (meaning you can do it at home) and not too much time (meaning you can squeeze it in whenever). Beyond that, HIIT touts a number of health benefits: It can stoke your metabolism, help you lose weight, and take your fitness to the next level.

But as you know if you’ve ever done a HIIT workout, it can be very, very intense. And if you do something so intense for so long (and so often), it's not surprising that there’s a catch. Robin Berzin, M.D., an mbg Collective member and Functional Nutrition Program instructor, has seen many patients who consistently do HIIT workouts suffer from digestive troubles. How we move, she says, is important (and often overlooked).

“One patient of mine was doing high-intensity interval training almost every day, and it was actually overly stressing her body,” Berzin says. “What we know is that for the gut to move, it has to relax. And when you’re in a state of stress all day, and then you do high-intensity interval training over and over again, sometimes it never gives the gut that time to relax, digest, and move.”

In other words, HIIT is tough on the body, which can be great for strength and performance, but not so ideal for digestion. If you’re doing HIIT now and experience no symptoms, that’s awesome and you should keep doing what works. But if you’re a HIIT lover struggling with constipation, it may be time to make some changes.

Here's what you can do.

Since very intense, short bursts of exercise could be what’s causing your issue, it makes sense that the remedy lies in doing the opposite. As Berzin says, our digestive tract needs time to move and relax, which means lower impact and lower intensity workouts are the way to go—specifically restorative workouts.

“Incorporate more restorative exercise, more pilates, more yoga, and more walking,” Berzin suggests. “We also advised her to stop doing HIIT workouts so close to when she was eating—this would give her digestive system a chance to do its job well.”

Now to be clear: We’re not advising that you stop doing HIIT altogether, forever and ever. After all, HIIT has numerous benefits, and we’re not one to tell you to ditch your workout or sacrifice stress relief.

What we are saying is that constipation is a real condition with unpleasant, often painful, side effects—so why not throw a few yoga classes or weekend walks into your mix and see how you feel? At the very least, you’ll be less stressed, which, when it comes to digestion, can actually only help.
