Sad news from the Welsh village I spent my summers at as a child came in a few weeks back. My dad’s mate’s son passed away unexpectedly at 35. No cause of death was initially revealed until the coroner confirmed “diabetic ketoacidosis” (I’ve typed that from memory.) I did Google it to try and find out more but it didn’t make any sense to me. Can anyone explain what it is and what may have happened to claim him? We’d played as kids and it’d settle my mind to know a bit more. Thanks.
