Hello
@NB24. So sorry you have this concern for your mother’s wellbeing.
Care for relatives when they no longer have capacity to care for themselves can get very complicated. Less so if they have Registered Power of Attorney in place for health and financial decisions. I hope your mother has this, but if not as a next of kin / relative, you have right to access care on her behalf.
In a similar situation, I would contact your mother’s Local Council, Adult Services and ask for a Needs Assessment. From what you have told us, it seems she is in urgent need of care, more than has already been offered. If she lacks capacity, and is on her own, she would not be able to seek assistance for hypos, and could become very ill, very quickly. It can be difficult to get the right care in one’s own home, and perhaps her doctor could support you in finding the help from the Local Authority that is mandatory in circumstances like this. I would be very assertive in dealings with the Local Authority and Health Services to ensure her needs are met.
