Not being able to hold the stool may be a precursor of anal disease and neurological disease. 1. Anal Disease: Usually the anus controls bowel movements through the anal sphincter, and if there is a problem with the anal sphincter, the patient will not be able to hold their bowel movements. Common anal sphincter problems include senile anal sphincter relaxation, hemorrhoids, and anal fistula, which may lead to anal incontinence. 2. Neurological disorders: These include spinal cord lesions and anal neuropathy, which usually result in the inability of the nerves to innervate the muscles, which may lead to obstruction of anal contraction, resulting in the patient’s inability to hold in his or her bowels. There may be other reasons for not being able to hold their bowels, so it is recommended that patients actively seek medical attention to clarify the cause of the disease and then carry out standardized treatment.
