Bill: This is not necessarily an auto-immune disease. It can be attributed to it BUT it also can happen from abdominal trauma, peritonitis, sepsis, etc., multiple abdominal surgeries, etc. There are different stages with it. We have a great group with ages ranging from 17 months old to 70 years old and approx 85 in our group – with many being in their 20-40’s. My daughter was 14. Have they done a biopsy yet? Diagnosed with scans? CT? Biopsy? please feel free to PM me.
