But obviously you're very concerned about her health.
When I've been in similar situations, I called EMS. I had to be firm and advise that I couldn't take take of someone if he wouldn't cooperate and get help when needed.
Thinking over your mother's drastic weight loss, that might be the route to take. I suspect when they check vitals they'll find something out of range and that may justify their taking her to the ER, which may be the only way you'll get her to go.
I think though that she's not able to care for herself properly, and to me that would equate to the fact that she's a danger to herself, although I also suspect she's in denial and doesn't understand she's flirting with danger.
Has your mother executed a Living Will or what's often called a medical power of attorney, and if so, are you named as having the authority to make decisions on her welfare? If so, read it well and confirm that you have the authority, then call EMS.
Your mother may get mad at you and make a scene when the paramedics come, as I get the impression she's an independent person even if she needs help.
Good luck; I know this must weigh heavily on your mind.
Wish I had some better suggestions.
Does she get Meals on Wheels (even though meat is provided) or prepare her own meals?
Your profile states that you're caring for her. I assume you don't live with her? It doesn't sound as if she should be alone. Have you given any thought to an alternate possibility, such as assisted living (if she's up to it)?
Take her to a doctor ASAP, as FF suggested, her primary doctor or an internist. Actually, I might even take her to the ER; that level of weight is dangerous.
I don't know who told you there's nothing that can be done if she's not a danger to herself or others. That's nonsense; losing that much weight IS a danger.
