Diabetes mellitus results in neuropathy of both somatic and visceral nerves. In diabetic patients with faecal incontinence, impaired rectal sensory function, manifested by a decreased sensitivity to balloon distention is common. This may contribute to unawareness of rectal filling and incontinence. There has been little study to date of visceral mechanosensation in experimental diabetes however. We hypothesized that experimental diabetes would impair mechanosensitivity in rectal afferent nerves. Diabetes was induced in rats by i.p. injection of streptozotocin. Controls were injected with citrate. In vitro recordings were performed from rectal afferent nerves innervating isolated segments of rectum. In control animals, three …
