I have been in denial about the possibility of me having Fructose Malabsorption for far to long now. I know i have something wrong with my digestion and i know i have mild acne but i have never been able to work out what is causing either and whether there is a connection at all between the two. After years of messing around with one hting and another, taking god knows what vitamins and supplements, without really putting too much effort in, i am now going to focus on the possibility i may have some kind of Fructose Malabsorption.
What has led me to make this connection
I have always had mild digestion problems. I have never really worked out for sure what causes them.
Sometimes when i eat fruti with other foods i get bloating/gas and pain/cramps.
Tomato based dishes such as pasta and sardines on toast.
Onion bhajis are probably the worst culprit.
I thought it might be gluten, tried not eating it for a few weeks = no noticable change.
Thought it might be dairy, tried not eating it for a few weeks = no noticable change.
Because of tomatoes i thought it might be histamines, tried not eating it for a few weeks = not much change.
Now the worst one. I read about fructose and fruit causing problems and even though i thought it was a load of BS i entertained the idea and tried not eating for a few weeks. Now i do think i noticed some improvement but because i was probaly against the idea from the start i just dismissed any results i saw.
After years of half hearted "research" and "experimentation" the only possible explanation for my problems i can find, that could possibly explain my symptoms and maybe a connection between them is Fructose malabsorption.
Fructose Malabsorption is a digestive disorder in which absorption of fructose is impaired by deficient fructose carriers in the small intestine's enterocytes. This results in an increased concentration of fructose in the entire intestine.
Fructose is absorbed in the small intestine without help of digestive enzymes. Even in healthy persons, however, only about 25-50g of fructose per sitting can be properly absorbed. Persons with fructose malabsorption may absorb less than 25g per sitting (NB: Amount is arbitrarily determined according to investigation of fructose absorption in many individuals). In the large intestine, fructose that hasn't been adequately absorbed osmotically reduces the absorption of water and is metabolized by normal colonic bacteria to short chain fatty acids and the gases hydrogen, carbon dioxide and methane. This abnormal increase in hydrogen is detectable with the hydrogen breath test.
The physiological consequences of fructose malabsorption include increasing osmotic load, providing substrate for rapid bacterial fermentation, changing gastrointestinal motility, promoting mucosal biofilm and altering the profile of bacteria. These effects are additive with other short-chain poorly absorbed carbohydrates such as sorbitol. The clinical significance of these events depends upon the response of the bowel to such changes; they have a higher chance of inducing symptoms in people with functional gut disorders than asymptomatic subjects. Some effects of fructose malabsorption are decreased tryptophan, folic acid and zinc in the blood.
Restricting dietary intake of free fructose and/or fructans may provide symptom relief in a high proportion of patients with functional gut disorders, but quality evidence may be lacking.
- I have always had a gut feeling that my internal bacteria were some how playing a role in my acne but i was never sure what.
- Bloating (from fermentation in the small and large intestine)
- Diarrhea and/or constipation
- Stomach pain (as a result of muscle spasms, the intensity of which can vary from mild and chronic to acute but erratic)
- Vomiting (if great quantities are consumed)
- Early signs of mental depression
Obviously as there is a diagnosic test it would make sense for me to get this done first, but because of one thing and another this isn't an option and i will just be adjusting my diet first to see what happens.
