This patient most likely has Diabetes and is currently in a hyperosmolar hyperglycemic state, where he experiences dehydration and increased serum osmolality due to increased levels of glucose in the body.
Note: insulin levels are usually normal to high, thus why there is no ketone production and no acidosis.
Chron's causes transmural inflammation that can potentially cause perforation (peritonitis and sepsis bc of spilled abdo contents). That would also explain the adhesions as a result of the damage. Additionally the damage occurred in the SI where only Chron's can cause damage in contrast to UC. Finally, the granuloma in the picture is hallmark of the "Chronulomas" of Chrons; UC causes crypt abscesses.
