Prescription medications

According to the National Institutes of Health (NIH), medications that may help chronic idiopathic constipation include:

The medications increase the frequency of bowel movements and help the colon move stool.

Some options may be available over the counter. Always talk with a doctor or pharmacist before trying new medications or remedies, even if they are available without a prescription.

Pelvic floor rehabilitation

Pelvic floor rehabilitation involves specific exercises to improve control of the bowel and bladder muscles.

Clinicians may also include biofeedback during rehabilitation. Biofeedback involves placing a small device in the rectum before doing pelvic floor exercises. The device is linked to a monitor that provides feedback to help you learn how and when to strengthen and relax your muscles.

Nerve stimulation

If other therapies do not treat your constipation, doctors may consider sacral nerve stimulation.

With sacral nerve stimulation, clinicians use gentle electrical pulses to stimulate the pelvic nerves to improve bowel function. To do this, a surgeon places a small electrode under the skin in the lower back. Afterward, you will use a handheld device to control the electrical pulses.

However, one 2017 study Trusted Source PubMed Central Highly respected database from the National Institutes of Health Go to source reported that only a small number of people experienced long-term benefits from sacral nerve modulation for chronic constipation. Also, surgery may not be suitable for everyone.
