Fructose malabsorption and sorbitol intolerance

Your doctor assesses symptoms and whether tests are useful. With known or suspected hereditary fructose intolerance, do not try foods at home: specialist care and prescribed exclusions take priority. This support concerns digestive malabsorption.

The amount of fructose at one time and its excess relative to glucose often affect tolerance. We adjust portions and spread fruit intake rather than removing all fruit. Adding sugar is not a treatment strategy.

Sorbitol may worsen symptoms, particularly alongside fructose. Juice, dried fruit, honey, syrups and sugar-free products containing polyols are reviewed in the amounts actually consumed. Labels help understanding rather than creating a blacklist.

A short food and symptom diary helps test one change at a time. After targeted reduction, reintroductions identify tolerated amounts. The goal is variety and adequate fibre, not a lifelong sugar-free diet.

Symptoms after particular fruit do not mean everything must go: amount and context matter.

• Juice, several close portions or sorbitol chewing gum create a different load from one whole fruit alone.
• "Sugar-free" products deserve attention too, as some contain polyols.
• A brief record notes the food, amount and context rather than permanently banning one fruit.
• Persistent or new symptoms need medical assessment, especially with weight loss, blood in stools or night waking.
• A single uncomfortable meal does not define your long-term tolerance.

Absorption of fructose and sorbitol varies, which explains symptoms without an allergic reaction.

• Fructose absorption varies with the dose and meal composition.
• Sorbitol, a polyol, may also be incompletely absorbed.
• Unabsorbed amounts draw water and ferment in the colon, causing symptoms without allergy.
• This common malabsorption differs from hereditary fructose intolerance, a rare disease needing specialist follow-up.
• If suspected, no home trials: medical specialists set the dietary instructions.

For ordinary malabsorption, Gabriela adjusts portions and preparations while preserving variety.

• Gabriela helps adjust a portion, space out servings or choose another preparation.
• Drinks and sweets are reviewed too, so fruit is not blamed alone.
• Trials change one variable at a time, returning to tolerated foods.
• Assessing other FODMAPs stays supervised and temporary, never a strict lifelong diet.
• The goal preserves fibre, energy and enjoyment, with solutions fitting your family meals.

Labels can help identify sorbitol in sweets, chewing gum and other packaged foods. Review the amount usually eaten, because a small serving and several servings together may have different effects. Do not assume that every product marketed as healthy will be comfortable for your digestion.
