Fructose Intolerance

Fructose intolerance, also known as fructose malabsorption, is a digestive disorder where the small intestine cannot properly absorb fructose, a sugar found in fruits, some vegetables, and honey. This condition can lead to gastrointestinal symptoms such as bloating, diarrhea, and abdominal pain after consuming foods high in fructose. If you suspect you have fructose intolerance, contact Digestive System Healthcare to consult with our specialists and get a proper diagnosis and management plan.

What are the causes of fructose intolerance?

Fructose intolerance occurs due to the body’s inability to absorb fructose efficiently in the small intestine. This can be caused by:

Enzyme deficiency:
- Insufficient levels of the enzyme needed to break down fructose
Intestinal health:
- Damage or inflammation in the intestines affecting nutrient absorption
Genetics:
- Hereditary fructose intolerance, a rare genetic disorder where the liver lacks the enzyme needed to metabolize fructose

What are the symptoms of fructose intolerance?

Common symptoms of fructose intolerance include:

Abdominal pain and cramping
Bloating and gas
Diarrhea
Nausea
Symptoms usually appear shortly after consuming fructose-containing foods and can vary in severity.

Are there ways to manage fructose intolerance?

Managing fructose intolerance primarily involves dietary changes to reduce or eliminate fructose from your diet. Some strategies include:

Avoiding high-fructose foods:
- Limit or avoid fruits such as apples, pears, and mangoes
- Avoid sweeteners like high-fructose corn syrup and honey
Choosing low-fructose alternatives:
- Opt for fruits like berries, citrus fruits, and bananas in moderation
- Use glucose or dextrose-based sweeteners instead of fructose-based ones
Reading food labels:
- Check ingredient lists for hidden sources of fructose
Working with a dietitian:
- A registered dietitian can help create a balanced diet plan that meets your nutritional needs while avoiding high-fructose foods

When should you seek medical help for fructose intolerance?

It’s important to consult a healthcare provider if you experience:

Persistent gastrointestinal symptoms after consuming fructose-containing foods
Unexplained weight loss
Signs of malnutrition or nutrient deficiencies
Severe or worsening symptoms
