An abnormal opening between the rectum and vagina that may cause leakage of stool or gas.
The evidence that matters most is a clear record of how often vaginal fecal leakage occurs and whether you must wear a pad because of it. Medical records from a gastroenterologist, colorectal surgeon, or gynecologist that document the frequency of leakage are directly relevant. Notes from primary care visits, specialist evaluations, or a VA Compensation and Pension exam that state how many times per week or day leakage occurs will help establish which rating level applies.
Your own written statement, or a statement from someone who lives with you, describing the day-to-day reality of leakage frequency and pad use can also support the medical record. Prescription or purchase records for pads or absorbent products may help confirm that wearing a pad is required. If symptoms have changed over time, records showing that pattern are useful because the frequency of leakage is what separates each rating level from the next.
Conditions that are often caused or made worse by this one. If you have any of these, they may be claimable as secondary service connection.
