Fructose Malabsorption

Posted by CL @lelia, Dec 5, 2018

I'd like to start a discussion on fructose malabsorption, how to control it, what to eat and not eat, etc. . Is anybody interested?

Interested in more discussions like this? Go to the Digestive Health Support Group.

I was hoping there was a medication specifically for fructose malabsorption but that doesn't seem to be the case.
Any diet suggestions?

Hello.
The malabsorption may be related to IBS or irritable bowel syndrome. I do not absorb fructose either, but that goes along with my IBS. I was diagnosed with IBS many years ago and told that a low FODMAP diet would help. After looking into this more thoroughly I purchased a book by Patsy Catsos and it was extremely helpful. Along with the dietary changes I also take digestive enzymes. This combination has done wonders for me. Hope you get some relief.

Thank you for your response. Could you share the names of the digestive enzymes you take?

From a recent article in "Today's Dietician, a publication specifically for people working in the field comes this extract:
"FODMAPs are a class of carbohydrates that are poorly absorbed in the small intestine and highly fermentable in the large intestine. There are five categories of FODMAPs: lactose, fructose, fructans, galacto-oligosaccharides (GOS), and polyols.24 ...

Xylose isomerase, fructan hydrolase, and inulinase, which are used in industrial syrup production, also may have applications for symptom management in IBS.25,26 A , double-blinded, placebo-controlled study found that supplementation with 43 mg of xylose isomerase significantly reduced breath hydrogen excretion, abdominal pain, and nausea when administered with 25 g of fructose in individuals with fructose malabsorption, which was diagnosed based on breath testing. There was no significant impact on bloating.25 While this study included only individuals with positive fructose breath tests, research suggests that patients with IBS respond positively to a low-fructose diet independent of fructose breath test results.27 Xylose isomerase, therefore, may have applications for aiding fructose breakdown in a broader population of patients with IBS, though more research is needed to explore its potential benefits in IBS patients."

Perhaps you can take article about enzymes - specifically Xylose isomerase, to you provider, and see if it is a possibility for you - it will probably depend on your symptoms and the severity.

I am very sensitive to FODMAPs and much more. For carb issues, like fructose, I take Intoleran's Fructase enzyme supplement (I actually take all of their supps, I am so sensitive).

I not only have malabsorption to fructose, but tomatoes, onion, garlic, and gluten. It’s a struggle to find things to eat. It seems like I’m eating the same things just to be safe. IBS caused by nerve damage to celiac plexus nerves caused by Mesenteric Artery Ligament Syndrome.

That sure sounds like a FODMAP issue to me. Just eat what works for you. That is what I do and I tell friends and family "I can only eat 15 things." Try the Monash University FODMAP app. It is a godsend that researches food on its FODMAP level. Very worth it.

I empathize with you. I get very sick and bloated these days from anything ending in "ol." Stupidly, just yesterday, I ate an avocado not realizing that the sugars it releases are erythritol. If I didn't know better, I woukd have thought my symptoms were worthy of the E.R!!
