Fecal incontinence
FI is a sign or a symptom, not a diagnosis, and represents an extensive list of causes. Usually, it is the result of a complex interplay of several coexisting factors, many of which may be simple to correct. Up to 80% of people may have more than one abnormality that is contributing. Deficits of individual functional components of the continence mechanism can be partially compensated for a certain period of time, until the compensating components themselves fail. For example, obstetric injury may precede onset by decades, but postmenopausal changes in the tissue strength reduce in turn the competence of the compensatory mechanisms. The most common factors in the development are thought to be obstetric injury and after effects of anorectal surgery, especially those involving the anal sphincters and hemorrhoidal vascular cushions. The majority of incontinent persons over the age of 18 fall into one of several groups: those with structural anorectal abnormalities (sphincter trauma, sphincter degeneration, perianal fistula, rectal prolapse), neurological disorders (multiple sclerosis, spinal cord injury, spina bifida, stroke, etc.), constipation/fecal loading (presence of a large amount of feces in the rectum with stool of any consistency), cognitive and/or behavioral dysfunction (dementia, learning disabilities), diarrhea, inflammatory bowel diseases (e.g. ulcerative colitis, Crohn's disease), irritable bowel syndrome, disability related (people who are frail, acutely unwell, or have chronic/acute disabilities), and those cases which are idiopathic (of unknown cause). Diabetes mellitus is also known to be a cause, but the mechanism of this relationship is not well understood.
Mental disorders diagnosed in childhood
As part of the treatment, family members and friends are advised not to call attention to the tics when the child is performing them. If they do, the child may develop more tics more frequently. Behavioral therapy and medication are often the choices of treatment for tic disorders in children.Encopresis: The most common cause of encopresis is constipation. When a child becomes constipated, feces build up in and stretch the rectum. This stretching causes the nerve endings to become dull. The child may not feel when they need to eliminate the feces or if the waste is coming out. Inside the rectum, the feces could become too large or solid to eliminate without feeling pain. While the mass of feces is stuck in the child's rectum, liquid feces could leak from around the mass and out of the child's body. The main causes of constipation are diet, lack of sufficient amounts of water, stress, not enough exercise, and inconsistent bathroom routines.
