Constipation / Anorectal Physiology Testing

Anorectal physiology tests are safe, low risk procedures and are unlikely to cause any pain. Please inform the doctor if you experience any discomfort or pain or wish to pause for a while during the tests. If you are allergic to latex, you should inform the doctor before the test so that a latex free balloon can be used.
