Other disorders of intestinal carbohydrate absorption

Intestinal carbohydrate absorption is a complex process that involves several enzymes and transporters. Disorders that affect this process can lead to a range of symptoms, including diarrhea, bloating, and abdominal pain.

While most people are familiar with lactose intolerance, there are other disorders of intestinal carbohydrate absorption that are less well-known. In this article, we will discuss some of these disorders and their symptoms.

1. Sucrase-isomaltase deficiency: This disorder is characterized by a deficiency in the enzymes sucrase and isomaltase, which are needed to break down sucrose and starch. Symptoms of sucrase-isomaltase deficiency include diarrhea, abdominal pain, and bloating. This disorder is typically diagnosed in infancy or early childhood, and treatment involves a low-sugar, high-protein diet.
2. Fructose malabsorption: Fructose is a simple sugar found in many fruits and vegetables. In people with fructose malabsorption, the small intestine is unable to absorb fructose properly, leading to symptoms such as bloating, abdominal pain, and diarrhea. Treatment involves avoiding foods that are high in fructose.
3. Glucose-galactose malabsorption: This disorder is caused by a deficiency in the transporter proteins that are needed to absorb glucose and galactose. Symptoms include diarrhea, dehydration, and failure to thrive. Treatment involves avoiding foods that are high in glucose and galactose.
4. Disaccharidase deficiency: Disaccharidases are enzymes that are needed to break down certain types of carbohydrates. Deficiencies in these enzymes can lead to a range of symptoms, including diarrhea, abdominal pain, and bloating. Treatment involves avoiding foods that are high in the specific disaccharide that is not being absorbed properly.
5. Celiac disease: Celiac disease is an autoimmune disorder that affects the small intestine. People with celiac disease are unable to tolerate gluten, a protein found in wheat, barley, and rye. Symptoms of celiac disease include diarrhea, bloating, and weight loss. Treatment involves following a gluten-free diet.

If you are experiencing symptoms such as diarrhea, bloating, or abdominal pain, it is important to speak with your healthcare provider. They can help determine the underlying cause of your symptoms and develop an appropriate treatment plan.

By understanding these lesser-known disorders of intestinal carbohydrate absorption, you can be better equipped to identify and manage your symptoms.
