Name changed as this is sensitive.
Two obese members of my family died prematurely, I'm not an expert but I believe their weight was the ultimate cause and that it was years, decades in fact, in the making.
Both had a similar story which started with falling and crushing their own hip, then needing to use a walking stick for years & years, only walking short distances to/from the car and as they got into their late 60s, became unable to fit into a driver's seat & only moving within their homes, putting on more weight & needing to order special shoes and clothes that fit comfortably.
Then came the issues that come from not moving & being overweight like swelling, sores, bad circulation, infection, joint issues, dizziness etc and it just escalated until they were in hospital unable to fight anything off and the doctors could do nothing to help them.
In hospital one of my relatives was too embarrassed to ask to go to the loo as she felt like a burden needing several members of staff and a winch to lift her each time. At their funerals both coffins had to be rolled in on wheels as they were too heavy for a group of men to carry.
I now fully expect this to happen to a third member of my family who is getting old and has been obese my whole life. I'm dreading seeing him with a walking stick but I know nothing I do or say will make any difference so I say nothing.
Sorry if people don't like to hear the reality but your health affects the people who love you - whether they express it or not - and I guess can't help but feel some sense of ownership or wanting to do something to help out of fear for the future.
I urge anyone worried about their weight to seek help - find out what is the root cause and tackle that. Nothing serious will happen overnight or even in the next 10 years but I've seen how it creeps up.
