Lumpy stools at the anus may be caused by a poor diet in recent times. For example, eating too much chili, pepper, alcohol, tobacco, coffee, or hard foods recently can make the stool dry and hard, making it difficult to pass. If the bowel movement is hard, the skin of the anus may be torn, which means that anal fissures may occur. It may also be due to secondary constipation and insufficient gastrointestinal motility, causing the stool to remain in the anal canal for too long, evaporating the water in the stool and making the stool too dry, requiring softening with a corking gel and regulation with eating intestinal probiotics. It may also be caused by the weakness of the anal sphincter due to the patient being bedridden for a long time. Considering that the cause is complex, it is recommended that patients go to the hospital for further examination and then targeted treatment.
