The most common cause of oily stools is indigestion, which can also be caused by chronic gastroenteritis and gastric ulcers. It is best to check the stools carefully to see if they are dark red in color, as bleeding in the digestive tract may also cause the stools to be dark red and oily. Normal stools are golden yellow in color and are not particularly oily. If the color of the stool is abnormal, it is recommended to have it checked in time. If it is gastroenteritis, gastric ulcer caused by shiny stools, you can take oral rabeprazole, morpholine and other drugs for treatment. If it is caused by indigestion, it is recommended to take oral gastrointestinal tablets, lactobacillus tablets and other drugs to promote digestion and enhance intestinal peristalsis. If the test result is gastrointestinal bleeding, you must be admitted to the hospital.
