The white color of stool after using Ma Ying Long Hemorrhoidal Ointment may be caused by the drug itself, or it may be caused by diseases of the liver and gallbladder system. 1. Drug reasons: Ma Yinglong hemorrhoid cream color has light gray-yellow or pink, but in the decomposition of the drug can form a white substance, defecation, the first discharged feces surface can be white. 2. Liver and gallbladder diseases: when there is jaundice, gallstones, pancreatic head cancer and other diseases, it will cause bile excretion obstacles, no bile in the feces will cause white stools. It is necessary to improve the relevant examination and timely treatment.
