Your treatment options

Treatment is matched to how severe your condition is and how it affects your daily life. Compare the approaches below.

  • Stool softeners and a high-fibre diet

  • Warm sitz baths

Surgical treatment

If a fissure does not heal after 6 to 8 weeks of treatment, a minor procedure called lateral internal sphincterotomy may be recommended. It relaxes the muscle to let the tear heal.

Ask if this suits you

Laser and minimally invasive treatment

Laser-assisted treatment may be offered for chronic fissures and can reduce post-operative pain for some patients.
