To diagnose your problem, your doctor will ask about your health history and will do a physical exam. The doctor will also ask about your symptoms.
When you describe your symptoms, include:
- Any food or physical activity that seems to cause your problem.
- How severe the leaking stool is.
- Related problems such as pain, constipation, or illness.
- When the leaking occurs.
You may need imaging tests, such as:
- Anal manometry. Your doctor uses a thin, flexible tube to check how well the muscles and nerves around your anus and rectum are working.
- MRI. MRI imaging may help find problems with the structure of your anus and rectum.
- Anorectal ultrasound. Sound waves make images of the structures in your anus and rectum.
- Proctography or defecography. This is an X-ray that helps your doctor find out how much stool you can store in your rectum and how your body handles stool.
- Proctosigmoidoscopy. Your doctor will use a flexible tube to look inside your rectum and lower intestine. They will look for scars, inflammation, or other conditions. In certain cases, you may need a colonoscopy. This test looks at the entire colon.
- Anal electromyography. This test looks for signs of nerve damage in the pelvic floor and rectum.
Your doctor may also ask about your emotional health and quality of life. This is done to find out how the condition is affecting you. Fecal incontinence can lower self-confidence. And you may worry about everything from odors to your appearance.
