Fructose
malabsorption can be diagnosed using a hydrogen breath test, which recognizes
unabsorbed fructose. The foods we eat are made up of many components, including
sugars. Fructose is a sugar found naturally in many foods, including honey,
wheat, fruits and vegetables. Fructose is present in a single sugar form and
also as a chain of fructose sugar units (fructans). Normally, fructose is
absorbed in the small bowel. In fructose malabsorption, the normal absorption
of fructose is impaired.

In my experience, dietary avoidance (FODMAP diet) is not a long-term solution in managing Fructose intolerance. As a Naturopath, I work differently compared to dieticians. I investigate the cause of fructose intolerance through functional clinical testing. The urinary indican test is one of the tests that I use to determine the amount of bad bacteria in your digestive system. By combining this with a thorough 90 min clinical case taking - it narrows down the root problem of your health issue.
Most causes of fructose intolerance can be pin pointed to SIBO (small intestinal bacteria overgrowth). A relatively new term for most, symptoms of SIBO include bloating, gas, constipation / diarrhoea, abdominal pain, belching & flatulence, nausea, reflux and fatty stools. Other signs include: worsening of symptoms when on prebiotics, xylitol or sugar alcohols.
3 tips:
1) Short term management: Get familiar with FODMAP foods and only avoid when necessary. Keep a food diary to document the foods that affect you.
2) Once SIBO is suspected, your Naturopath will put you on a herbal anti microbial treatment.
3) Healing the gut wall: Through gut healing nutrients such as glutamine, zinc and vitamin A. This reduces inflammation and prevents the gut from getting aggravated from certain foods.
3) Support the digestive system: The digestive system requires support through herbal tinctures or digestive enzymes to help facilitate its function.
