It is possible to drink milk for bile duct obstruction, but you must be careful to drink it in moderation. Bile duct obstruction is usually bile duct stones. Bile duct stones are caused by abnormal ratio of bile acid phospholipid concentration, bile sludge, bile duct infection, etc., which leads to bile duct obstruction, resulting in yellowing of the skin, yellowing of the sclera, and itching of the skin. Milk contains protein, calcium and other substances that do not lead to the occurrence of bile duct stones. Drinking more milk can promote nutrition in the body, but drinking more milk can cause constriction of the bile ducts, which can cause pain. People with bile duct stones that cause obstruction of the bile ducts can drink yogurt, rice porridge, etc., but they should not eat greasy, spicy, or irritating foods. If the patient has an adverse reaction after drinking milk, early standardized treatment is recommended to reduce the adverse effects of the disease.
