E73.8
Other lactose intolerance
Clinical Classification Guidelines
Medical Intelligence & Overview
Other lactose intolerance, classified under ICD-10 code E73.8, refers to a condition where individuals experience difficulty digesting lactose—the sugar found in milk and dairy products—due to specific deficiencies or conditions that do not fit into the more common types of lactose intolerance. Unlike primary lactose intolerance, which develops gradually over time, this form may result from other health issues affecting the digestive system's ability to process lactose. Recognizing and understanding this condition helps in managing symptoms and improving quality of life.
Causes & Symptoms
Clinical Causes: Damage to the small intestine lining caused by infections or diseases such as celiac disease or Crohn's disease Surgical removal of parts of the small intestine that produce lactase Congenital lactase deficiency, a rare genetic disorder where the body produces little to no lactase from birth Secondary lactose intolerance due to injuries or conditions affecting the intestinal mucosa Certain medications that impair lactase production temporarily or permanently
Key Symptoms: Bloating and abdominal distension after consuming dairy products Diarrhea or loose stools following dairy intake Stomach cramps or pain in the lower abdomen Nausea and sometimes vomiting Gas and increased flatulence
Diagnostic & Treatment
Diagnosis Path: Diagnosing other lactose intolerance typically involves reviewing medical history and dietary habits, followed by specific tests such as: - **Lactose Tolerance Test**: Measures blood glucose levels after consuming a lactose-rich beverage. - **Hydrogen Breath Test**: Detects increased hydrogen in the breath after lactose ingestion, indicating improper digestion. - **Stool Acidity Test**: Mainly used in children, assessing acidity in stool samples. - **Intestinal Biopsy**: Occasionally performed to evaluate mucosal health in uncertain cases. These diagnostic procedures help determine the body's ability to digest lactose and identify potential underlying conditions.
Treatment Protocols: Management strategies focus on reducing symptoms and maintaining nutritional balance, including: - **Dietary Adjustments**: Limiting or avoiding dairy products containing lactose. - **Lactase Supplements**: Taking over-the-counter lactase enzyme pills to aid digestion. - **Alternative Calcium Sources**: Incorporating non-dairy foods rich in calcium such as leafy greens, fortified plant-based drinks, and nuts. - **Monitoring and Education**: Understanding labels and ingredients to prevent accidental dairy intake, and working with dietitians to ensure nutritional needs are met. - **Treating Underlying Causes**: Addressing any underlying intestinal conditions that contribute to secondary lactose intolerance.
