ICD-10: E74.3

ICD-10 code E74.3 refers to "Other disorders of intestinal carbohydrate absorption," which encompasses a range of conditions that affect the body's ability to absorb carbohydrates from the gastrointestinal tract. Understanding this code involves exploring its clinical description, associated conditions, and implications for diagnosis and treatment.

Clinical Description

Definition

E74.3 is classified under the broader category of E74, which pertains to disorders of carbohydrate metabolism. Specifically, E74.3 addresses conditions that lead to malabsorption of carbohydrates, resulting in various gastrointestinal symptoms and nutritional deficiencies. These disorders can arise from genetic factors, infections, or other underlying health issues that impair the intestinal lining's ability to absorb carbohydrates effectively[1][2].

Symptoms

Patients with disorders classified under E74.3 may experience a variety of symptoms, including:
- Diarrhea: Frequent, watery stools due to unabsorbed carbohydrates in the intestines.
- Abdominal pain and bloating: Resulting from fermentation of undigested carbohydrates by intestinal bacteria.
- Flatulence: Increased gas production due to carbohydrate malabsorption.
- Nutritional deficiencies: Long-term malabsorption can lead to deficiencies in essential nutrients, impacting overall health and growth, particularly in children[3][4].

Associated Conditions

Congenital Sucrase-Isomaltase Deficiency

One of the notable conditions under E74.3 is congenital sucrase-isomaltase deficiency, a genetic disorder where the body lacks the enzyme necessary to break down sucrose and isomaltose. This leads to significant carbohydrate malabsorption, particularly from foods containing these sugars. Symptoms typically manifest in infancy and can include severe diarrhea and failure to thrive if not managed appropriately[5][6].

Other Disorders

Other disorders that may fall under this classification include:
- Lactose intolerance: While primarily classified separately, severe cases can lead to significant carbohydrate malabsorption.
- Intestinal infections: Certain infections can damage the intestinal lining, leading to temporary malabsorption issues.
- Celiac disease: Although primarily an autoimmune disorder, it can also result in carbohydrate malabsorption due to damage to the intestinal villi[7][8].

Diagnosis and Treatment

Diagnosis

Diagnosis of disorders under E74.3 typically involves:
- Clinical evaluation: Assessment of symptoms and medical history.
- Laboratory tests: Stool tests to check for unabsorbed carbohydrates, blood tests to assess nutritional deficiencies, and possibly genetic testing for congenital conditions.
- Endoscopy: In some cases, a biopsy may be performed to evaluate the intestinal lining for damage or abnormalities[9][10].

Treatment

Management strategies for E74.3 disorders focus on:
- Dietary modifications: Avoiding specific carbohydrates that exacerbate symptoms, such as sucrose in cases of sucrase-isomaltase deficiency.
- Nutritional support: Ensuring adequate intake of essential nutrients, possibly through supplements.
- Enzyme replacement therapy: In certain cases, enzyme supplements may be prescribed to aid in carbohydrate digestion[11][12].
