One treatment we consider for our patients is a stimulation known as interferential current. The use of electrical stimulation for reducing pain and muscle strengthening is well known. But this special current can help your GI tract move a little faster. For our patients, it's 2 electrodes on your abdomen and 2 placed on your back. It feels like a tingling sensation.
Studies on interferential current for slow transit show it increases colonic activity. Beyond that, there are some theories on the mechanism of action. A few of these theories include: it affects the pacemaker cells of the GI tract, stimulates the enteric nervous system to the GI tract, or it stimulates the cells that are responsible for peristalsis.
What we do know is that it is non-invasive, cost-effective, and can be done at home. Many patients that we talk to are on an endless search for supplements. Slow transit constipation typically does not respond to laxatives and fiber. Therefore, this may be a good option to reduce over the counter supplements and improve your transit time.
Our pelvic therapists would be happy to discuss this type of stimulation with you and determine if this should be a part of your treatment.
