In cases of resistant anismus (inability of the anal sphincter muscles to relax), medications and dietary changes often remain insufficient. One of the most effective modern treatment methods developed to overcome this mechanical obstacle in the muscles is Pelvic Botox (Botulinum Toxin) injection. Within the scope of pelvic floor health, this practical method with a high success rate is successfully performed in specialized clinics.
How Does Botox Work in Anismus?
Botox temporarily weakens the neural stimulation of the injected puborectalis muscle for 4 to 6 months. In this way:
- Paradoxical excessive contraction of the puborectalis muscle during defecation is prevented.
- The anal canal relaxes, the rectal angle aligns, and stool glides down easily without encountering any obstacles.
- The patient can defecate without the need to strain.
Reprogramming Muscle Memory
The primary goal of Botox application is to provide the patient with a "strain-free, painless, and comfortable defecation" experience for 4-6 months. Patients supported by pelvic floor physiotherapy during this period learn to relax their muscles correctly even after the effect of Botox wears off. Thus, the constipation problem is permanently resolved.
