Steatorrhea-like stools are generally lighter in color, larger in volume, frothy or greasy, and often float on the water surface when flushed, like a layer of oil slick, and smells bad, so it is easy to identify why steatorrhea-like stools occur, mainly because the absorption and digestive function of the small intestine is reduced, resulting in the intake of nutrients that are not fully absorbed, and thus intermingled in the stool. Therefore, people with steatorrhea-like stools are prone to a series of clinical syndromes called dyspepsia syndrome due to inadequate nutrient absorption, and need to be actively treated with replacement therapy and etiological treatment, such as intravenous high nutrition therapy, intravenous albumin therapy if hypoproteinemia occurs, and pancreatic enzyme tablets if pancreatic insufficiency is the cause. Most of the patients can be relieved of steatorrhea after eliminating the cause of the disease.
