But the year old IT supervisor from California also discovered another welcome, unexpected benefit from her new way of eating: it almost completely eliminated her long-standing irritable bowel syndrome IBS. Within a month of starting keto, her gut was remarkably calm, quiet, and cooperative for the first time in decades. Changing to a low-carb, high-fat diet completely resolved her constipation and reduced her formerly frequent attacks of diarrhea to less than once a month. In the past, I would have been in the bathroom within an hour. Most of us are ecstatic to broadcast our keto successes with weight loss or reversing type 2 diabetes. Talking frankly and honestly about gastrointestinal issues is squeamish stuff, the last taboo. For many, relief from IBS comes as a welcome surprise. Improvements in symptoms are commonly reported in emails to Diet Doctor. Many keto-themed blogs discuss the phenomenon, as do Reddit discussion threads.
To determine whether a low FODMAP diet—one that limits fermentable oligo-, di-, mono-saccharides and polyols that are not absorbed well in the small intestine—is less effective in individuals with IBS who carry the hypomorphic sucrase-isomaltase variant, the researchers re-evaluated results from a previous study. For the new study, the researchers stratified for the genotype. In all, 46 participants with the hypomorphic sucrase-isomaltase gene variant were identified for the new analysis. Overall,
A 4-week study in 13 people with diarrhea-predominant IBS found that the keto diet helped reduce pain and improve the frequency and consistency of stools While some of these claims may have merit, the diet is certainly not appropriate for everyone. All 13 participants who completed the 6-week study reported adequate relief of their IBS-D symptoms for at least two of the four weeks. Individuals with a history of inflammatory bowel disease, any gastrointestinal surgery, diabetes or other serious medical conditions, previous use of a VLCD, or use of narcotics or weight loss medications were ineligible. This distribution is consistent with those used in previous studies evaluating very low-carbohydrate diets. And all without a single medication. Proper stress management is recommended to help better manage IBS symptoms.
If you have irritable bowel syndrome IBS, you are willing to try anything in order to get in control of your symptoms. You are no stranger to dietary changes and have likely done your fair share of internet research while on the quest for answers. The keto diet is very low in carbohydrates, very high in fat, and moderate in protein. While some of these claims may have merit, the diet is certainly not appropriate for everyone. In fact, it may actually trigger your IBS symptoms! That being said, changes in the types and amount of fiber you eat can influence your IBS symptoms. Research suggests that a specific type of fiber called soluble fiber may help improve IBS symptoms. Soluble fiber is found in many high-carbohydrate foods such as beans, oats, carrots, and sweet potatoes. While there are some keto-friendly sources like avocados and flax seeds, it can be challenging to get enough soluble fiber from low-carb sources alone.
