K90-K93: Other diseases of the digestive system

The category titled "Other Diseases of the Digestive System" encompasses a range of conditions, primarily related to intestinal malabsorption and certain disorders of the gallbladder and biliary tract. Intestinal malabsorption is characterized by the impaired absorption of nutrients, fats, carbohydrates, proteins, vitamins, or minerals from the diet, leading to deficiencies. Causes can include diseases like Celiac or Crohn's disease, or damage to the small intestine. On the other hand, disorders of the gallbladder and biliary tract typically involve inflammations, obstructions, or gallstones, causing symptoms like abdominal pain, jaundice, and nausea. Disease progression varies widely according to the severity and specific nature of each condition. Overall, these conditions all lead to disruption of normal digestive processes, affecting individuals' nutritional status and overall health condition.
