Patients with rectal prolapse may experience a narrowing of their stool, which is primarily due to the relaxation of the rectal mucosa associated with rectal prolapse. The relaxed mucosa accumulates at the anus, blocking the passage of feces and thus altering the shape of the stool as it is expelled, generally resulting in thinner or flattened stools. Therefore, if it is definitively diagnosed that the change in stool shape is due to rectal prolapse, surgical treatment is recommended. The surgery involves excising or suturing the excessively relaxed rectal mucosa to allow for a smoother passage of stool and to prevent alterations in stool shape. Additionally, it is important for patients to maintain good lifestyle and bowel habits post-surgery, spend minimal time defecating, and avoid prolonged squatting or straining actions.
