Anasismus is a medical term used to describe a condition characterized by the inability to properly control or coordinate the muscles involved in defecation. It is a type of functional anorectal disorder, also known as paradoxical puborectalis contraction (PPC). This condition primarily affects the muscles of the pelvic floor and can lead to difficulties in passing stool effectively.
When an individual experiences anasismus, they may have an involuntary contraction or tightening of the external anal sphincter muscle and the puborectalis muscle, which surrounds the rectum and supports continence. This contraction can create an obstruction or resistance to the normal passage of stool, resulting in symptoms such as incomplete bowel movements, straining, constipation, and a feeling of rectal fullness.
The exact cause of anasismus is not fully understood, but it is believed to be multifactorial, involving both physical and psychological factors. It can be associated with conditions like pelvic floor dysfunction, irritable bowel syndrome (IBS), anxiety, or psychological stress.
Treatment for anasismus usually involves a multidisciplinary approach, combining behavioral modifications, physical therapy, and sometimes medication. Techniques like biofeedback, which helps patients become aware of and gain control over their pelvic muscles, can be effective in improving the coordination and relaxation of the muscles involved in defecation.
Overall, anasismus is a condition that disrupts the normal functioning of the pelvic floor muscles, leading to difficulties in defecation. Seeking medical attention can help address its underlying causes and alleviate associated symptoms.
