K90.8
Other intestinal malabsorption
Clinical Classification Guidelines
Medical Intelligence & Overview
Other intestinal malabsorption (ICD-10 code K90.8) refers to conditions where the small intestine fails to absorb nutrients properly, but the specific cause doesn't fall under more common categories like celiac disease or lactose intolerance. This condition can lead to nutrient deficiencies, weight loss, and various other health issues if left untreated. It is considered a diagnosis of exclusion, meaning it is identified after ruling out other specific causes of malabsorption.
Causes & Symptoms
Clinical Causes: Viral infections affecting the intestine Chronic inflammatory conditions Surgical removal of parts of the intestine Certain medications that impair absorption Rare genetic disorders impacting digestion Radiation therapy to abdominal area Diseases causing structural changes in the small intestine
Key Symptoms: Frequent diarrhea and loose stools Unintentional weight loss Nutritional deficiencies (e.g., iron, calcium, vitamins) Bloating and abdominal discomfort Steatorrhea (fatty, foul-smelling stools) Fatigue and weakness Signs of specific nutrient deficiencies, like anemia or bone pain
Diagnostic & Treatment
Diagnosis Path: Blood tests to identify deficiencies in vitamins and minerals Stool tests to detect fat content and parasites Breath tests to evaluate carbohydrate absorption Intestinal biopsy during endoscopy to observe tissue changes Imaging scans such as X-rays or MRI to assess structural anomalies
Treatment Protocols: Dietary modifications, such as low-fat diets or specialized nutritional plans Supplementation of deficient nutrients (vitamins, minerals, enzymes) Medication to control symptoms or underlying infections Management of complications like dehydration or anemia In some cases, surgical intervention may be necessary to remove damaged sections of the intestine Monitoring and ongoing nutritional assessment to prevent deficiencies
