I know it's hard to be on a diet, but if they don't want they shouldn't expect medical care/help. The main problem is if it comes to her, she isn't well-educated but says that everything that runs into the family. As long as people use these excuses, nothing will change. Next to that, the present attitude of WOKE that being fat HUGE or BIG is great is wrong. It's not if you have more and more health issues. She has, so she should slim down instead of taking more and more and higher doses of medication, which all have side effects, causing the same problems as the reason she started using them.
She's clearly not afraid; enough otherwise, she would have acted.
It is really worrying that they do not realize the danger of this thing. Although a person who is suffering from a disease should be very careful about his health, those who consider obesity to be healthy never pay attention to losing weight. I can only pray for your friend that Allah gives her health.
