Gastrointestinal disturbances associated with the consumption of sugar alcohols with special consideration of xylitol: scientific review and instructions for dentists and other health-care professionals. Is fructose malabsorption a cause of irritable bowel syndrome? Med Hypotheses. Your primary care provider can help to screen for more serious medical issues and should be informed of your exercise routine as well.Dinicolantonio JJ, Lucan SC. Exercise physiologists or certified personal trainers can provide exercise programming of appropriate intensity, and registered dietitian nutritionists can discuss individual nutritional needs and strategies. If you’re looking to start an exercise regimen or up the intensity of your current workouts, seeking the advice of trained professionals who can tailor a plan to your needs is often a smart approach. If you unfortunately do throw up, you’ll likely feel better but will also need to rehydrate and replenish the nutrition you lost. Sometimes the GI distress during or after exercise can actually lead to vomiting. If problems persist either for long periods after exercise or each time you work out, it’s worth having a conversation with your doctor. Most symptoms should resolve within an hour of finishing exercise. While exercise-induced nausea is unpleasant to deal with, in general it isn’t a major health concern.

It may take some experimentation with different foods and the timing of ingestion to figure out what works best for you and your training goals. Aim for about half a liter per hour of fluids, including some low-carbohydrate and low-sodium sports drinks for high-intensity exercise. Stay hydrated! You’ve probably heard it before, but drinking enough is one of the best ways to prevent GI issues during and after exercise, particularly in hot or humid environments. Be sure to properly warm up and cool down to prevent rapid changes in your body’s metabolism. Try different forms of exercise, or combinations of different modes to meet your fitness goals while minimizing discomfort. Some evidence suggests that certain exercises, like cycling, can put the body in a position that’s more likely to cause gut problems.

Especially if you’re newer to working out, gradually increasing exercise intensity should help to minimize the likelihood of GI distress. Nausea is more common with high-intensity exercise, where the competing demands for blood flow are highest.

So what can you do to limit symptoms or get rid of them when they crop up? It’s no fun to exercise if you’re doubled over with stomach cramps or running for the bathroom. The lack of blood flow is particularly challenging if the digestive system is actively trying to break down and absorb food, a main reason exercise-induced nausea can be worse right after you’ve eaten, especially if the pre-workout meal had a lot of fat or concentrated carbohydrates. Taken together, the changes result in an unpleasant feeling you may know all too well. It can change how cells are able to absorb what has been digested and how broken-down food moves through the gut. The relative ischemia, or lack of blood flow, can have different effects. So why does limiting blood flow to the gut cause distress? This resistance to the effect of the sympathetic nervous system is called “ functional sympatholysis.” Physiologists like me continue to work to understand the specific mechanisms by which this can occur. They’re able to resist the call for vasoconstriction that helps divert blood away from inactive areas. You don’t have conscious control over this process, known as vasoconstriction.īut your contracting skeletal muscles have a special power to preserve blood flow. Known as the sympathetic nervous system, it causes some blood vessels to narrow, limiting blood flow. This diversion is overseen by the “fight or flight” branch of your nervous system. To maximize the amount of blood being delivered to the active muscles, your body diverts blood away from inactive areas – such as your gut.
