Cholelithiasis, or gallstones, is one of the most common and costly of all the gastrointestinal diseases. The incidence of gallstones increases with age. At-risk populations include persons with diabetes mellitus, persons who are obese, women, rapid weight cyclers, and patients on hormone therapy or taking oral contraceptives. ⋯ Oral dissolution therapy is usually minimally successful and used only if the patient cannot undergo surgery. Laparoscopic cholecystectomy remains the surgical choice for symptomatic and complicated gallstones, with a shorter hospital stay and shorter convalescence period than open cholecystectomy. Percutaneous cholecystostomy is an alternative for patients who are critically ill with gallbladder empyema and sepsis.

Unintentional weight loss in persons older than 65 years is associated with increased morbidity and mortality. The most common etiologies are malignancy, nonmalignant gastrointestinal disease, and psychiatric conditions. Overall, nonmalignant diseases are more common causes of unintentional weight loss in this population than malignancy. ⋯ Treatment focuses on the underlying cause. Nutritional supplements and flavor enhancers, and dietary modification that takes into account patient preferences and chewing or swallowing disabilities may be considered. Appetite stimulants may increase weight but have serious adverse effects and no evidence of decreased mortality.
