Should i be worried wid the blood report

My mother has schizophrenia from the past 4 to 5 years and the psychiatrist asked for blood report.The blood report is attached.The doctor said it is a serious condition and you should see a diabetologist as soon as possible it is threatening as she can go into a coma.He has given metformin 500 mg for the time being. She is feeling nauseous after taking those pills and hence refusing to take them.She doesnt want to visit a diabetologist as she feels she doesnt need it. she has schzophrenia and she feels she has no blood in her body and will not let us take blood for further tests. She thinks we are giving her wrong medicines. Maybe she will give up taking this medicine metformin too. Currently for her schizophrenia she has been given spenzo 40 mg injection and tablets rpdone plus 3 mg. For her diabetes we are concerned.Is it possible that different pills or injection once a month can be given alongwith the spenzo injection? or avoiding sugar taking ayurvedic juice will help?
