Probably an 'impossible to say' question...

As the title says I'm not sure if my question can really be answered but I just thought I'd ask for my own mind if nothing else.
When I was first diagnosed 3 years I was the only one in my family (that we knew of) to have UC, that was until 2 years later when incredibly my 21 year old nephew was also diagnosed with the same condition. Truth be told, even though I would never wish this disease on anyone, it was nice to have someone to talk to about things as only those with the condition can really understand.
Anyway, my nephew sadly passed away suddenly at home 2 weeks ago. He was greatly overweight and had issues with over/secret eating stemming from some childhood traumas so we thought it was his heart that had given out however when the autopsy was done there was no obvious problems with his heart and no obvious reason for his death.
As his only other issue was the UC I was wondering if this could have contributed to his death. He did say he had his condition under control but he was also so secretive that it could be quite likely it wasn't and he just wasn't saying. As he was dying he complained of not being about to breath (COVID negative) and his stomach hurting.
The only medication he was on was Pentasa granules and suppositories.
I don't really know what I'm expecting from this post, I guess we are all just looking for some answers really, if there are any to be had.

very sorry for your loss - what a sad thing for all involved -

imo, it's a possibility that UC could have contributed but its seems unlikely it would have been the sole cause -

TT

Very sorry to read that your family suffered this tragedy. It could be that your nephew had a sudden severe asthma attack. That happened to a colleague of mine at age 38, who was otherwise healthy. He was walking on a beach with his wife (an RN!) when it struck him fatally within minutes. At work we were all terribly shocked to hear about that because he had a friendly, jovial personality, and was the kind of guy who did not "sweat the small stuff". Obesity might have complicated your nephew's resistance to some environmental irritant, bringing on his breathing struggle. Did he have any known allergies? / Old Hat (40 yrs with left-sided UC; presently in remission taking brandname Colazal)

Thank you for the replies and condolences.
Whatever resulted in his death definitely wasn't helped by his weight, his mother had asthma when she was younger but he never suffered with it himself.
I have my doubts that his UC was under control because we as a family were always trying to get him to address his weight issues, if he were to admit his UC wasn't under control he knew we would bring up his eating. I am lucky in that food doesn't affect my UC in either a positive or negative manner even when flaring so maybe he was the same but I can't imagine drinking litres of Coke or tubs of Pringles and fatty take outs daily would do anyone's colon any good.
I just don't know if UC would kill so quickly, I always assumed that dying from UC would be rare and generally speaking would happen over a long period of time where a person's body would gradually weaken.
I hope we do end up getting some answers, the not knowing is almost as hard as losing him.

Sometimes there are no clear answers as to why someone passes away. Your young nephew had many issues working against his potential for a long life. May he rest in peace.

Thank you for the replies. I agree UC is unlikely to be what killed him and maybe we will never really know.
Obesity is a horrible condition, where I live if you are an anorexic girl there are loads of services to help but if you are an over eating male there is nothing.
Anyways thanks again for the replies.
