Grace Moseley Life & Health Journey Summary
In Loving Memory of Grace Moseley (Michigan)
-------------------------------------------------------------------------
Date of Passing : Friday, June 19, 2026
Medical Condition : Superior Mesenteric Artery Syndrome (SMAS)
Clinical Status : Chronic Intestinal Failure / Severe Malnourishment
Primary Care Supporter: Mary Moseley (Mother)

-------------------------------------------------------------------------
Understanding Her Battle with SMAS
Superior Mesenteric Artery Syndrome (SMAS) is an incredibly rare, debilitating gastrointestinal condition characterized by the compression of the third portion of the duodenum by the abdominal aorta and the overlying superior mesenteric artery. For Grace, this structural blockage led to complete chronic intestinal failure.
-
The Nutritional Crisis: Prior to her passing, Grace’s condition became severely critical, dropping her body weight to 83 lbs.
-
The TPN Complications: Because her digestive system could no longer process food, her sole form of survival was Total Parenteral Nutrition (TPN)—intravenous nutrition delivered directly through her veins.
-
A Heroic Endurance: For 18 grueling months, TPN made Grace incredibly sick as her body struggled to tolerate it. Despite consulting with leading medical specialists across the United States, no clinical intervention could ease her daily, severe physical pain.
