People go for the 'biggies' when it comes to obesity - stroke, heart attack, diabetes. The picture is much more complex than that.
My DM died in March last year at 71. At 25st, she was 'fit and fat' - she didn't have diabetes, she had low cholesterol, she had low blood pressure. She spent her whole life telling me that her size was unimportant since all her health 'numbers' were OK.
She did, however, have a benign mystery mass over her left kidney which bled every now and again, causing her chronic anaemia.
No surgeon would touch her to remove it, however, because she was too fat for a GA.
This resulted in her having bags and bags of blood transfusions and iron infusions over years, gradually chipping away at her immune system.
She developed a strange abscess under her skin. This could easily have been evacuated, but again, no surgeon would touch her because she was too fat, and it was treated with masses of antibiotics and a colostomy bag to catch the endless exudate once it burst. That was horrible.
With repeated hospital admissions, her mobility, already awful because of the huge weight going into through her knees, became even worse, and I had the horror of looking for a residential home for her. I had 15 refusals, because of her size - she was too much of a risk to staff to evacuate in an emergency situation. I never told her any of this.
Two weeks after we finally got her placed, the (entirely fixable, but for her size) mass in her abdomen haemorrhaged and the (entirely fixable, but for her size) abscess under her skin went septic, and she was dead within 24 hours of admission to hospital, from the residential home she hated, and was mentally far too young for.
Please don't assume a life of indulgence means you'll go out in a quick and painless blaze of happy, over-indulged glory. And please, please consider the impact of your lifestyle choices on your loved ones, particularly those you may become dependent on. Being bitter towards my much-loved mother about her shitty decisions and self-delusions isn't much fun.
