Other disorders of intestinal carbohydrate absorption

Intestinal carbohydrate absorption disorders are a group of conditions that affect the ability of the small intestine to absorb carbohydrates, such as sugars and starches. These disorders can lead to a variety of symptoms, including diarrhea, bloating, and abdominal pain. While some of these conditions are well-known, such as lactose intolerance and celiac disease, there are other disorders of intestinal carbohydrate absorption that are less commonly discussed.

1. Sucrase-isomaltase deficiency: This condition is caused by a genetic mutation that affects the production of enzymes needed to break down sucrose and maltose. Symptoms of sucrase-isomaltase deficiency can include diarrhea, bloating, and abdominal pain after consuming foods that contain these sugars, such as candy, soft drinks, and baked goods.
2. Fructose malabsorption: Fructose is a type of sugar found in many fruits, vegetables, and sweeteners. In people with fructose malabsorption, the small intestine is unable to absorb fructose properly, leading to symptoms such as bloating, gas, and diarrhea. Foods that are high in fructose, such as apples, pears, and honey, may need to be avoided or limited in individuals with this condition.
3. Galactosemia: This is a rare genetic disorder that affects the ability to metabolize galactose, a sugar found in milk and dairy products. Infants with galactosemia can develop serious health problems if they consume milk or milk-based formula. Symptoms of galactosemia can include vomiting, diarrhea, and failure to thrive.

Other disorders of intestinal carbohydrate absorption include trehalose intolerance, glucose-galactose malabsorption, and congenital sucrase-isomaltase deficiency. These conditions are all relatively rare, but can cause significant discomfort and digestive problems for those affected.

If you experience symptoms such as bloating, gas, or diarrhea after consuming certain foods, it may be worth speaking with a healthcare provider to determine if you have a disorder of intestinal carbohydrate absorption. While treatment options vary depending on the specific condition, avoiding foods that trigger symptoms and taking enzyme supplements may be helpful in managing these disorders.
