Absolutely. What I'm saying is that I hope her doctor is making her aware that her weight could be creating the issues she's reporting, and at the very least, encouraging her to consider the possibility that her weight could be contributing to, if not outright creating, her health concerns.
Many times folks will dismiss their doctor's advice as "being mean" or unhelpful when it comes to suggesting a change in lifestyle when it's the first suggestion. They will suggest the patient to take control of their weight and see if the complaint or illness resolves, but it's not the answer everyone wants to hear.
Anecdotal, but many of the people I either know or interact with who complain of chronic illnesses and piss and moan on social media about their multiple health problems are usually obese. They will also complain their doctor "isn't listening" or that they're being discriminated against because the medical professional's go-to solution or answer to their troubles is usually "lose weight".
I got blocked by a relative (30-something year old woman who gained 150 in four years) on Facebook, because she complained that she needed to lose weight before she could be considered for a knee replacement surgery and decided that the doctor was overstepping, discriminating and brushing her off. I explained that you need to firstly be under a certain weight limit to qualify for certain surgeries, but was met with a flurry of excuses and was called ableist, etc.
Body positivity has turned people into victims and they'd rather suffer than find a solution. I hope Kat is not one of these people.
