Normal defecation requires proper anorectal sensation. Pelvic floor receptors are considered important in detecting the presence of feces in the rectum. Patients with fecal impaction and overflow incontinence have reduced rectal sensation, and patients with traumatic and idiopathic fecal incontinence (idiopathic fecal incontinence) may have abnormal anal canal sensation. Idiopathic fecal incontinence, or neurogenic fecal incontinence, is due to progressive damage to the nerves controlling the transverse muscles of the pelvic floor and the external anal sphincter, as well as reduced internal sphincter function. How to improve the diet if incontinence is caused by loss of anal canal reflex? 1. Consume enough water: Drink 6-8 glasses of water (about 2 liters) or other beverages every day and maintain a certain amount of urination to strengthen the natural defense function of the urinary tract, which can help prevent urinary tract infection. In addition, reducing alcohol, coffee, strong tea and sodas and other diuretic beverages will also help improve urinary incontinence. 2. Prevent constipation: Eat more fruits, vegetables and high-fiber foods, and drink the right amount of water every day, along with moderate exercise, can relieve constipation and improve incontinence caused by constipation.
