Severely uncontrolled Type 2 Diabetes (H

I am seeking a safe treatment plan for my mother (67 years old, female). She is highly frail and severely underweight, weighing between 30 to 40 kg. Our primary goal is to lower her blood sugar safely while avoiding any gastrointestinal side effects (like loose motions, stomach upset, or loss of appetite) and helping her achieve healthy weight gain.Her recent lab reports reveal:Fasting Blood Sugar: 278 mg/dLPost-Prandial (PP) Blood Sugar: 342 mg/dL (Urine Sugar: +++)HbA1c: 10.23% (Mean Blood Glucose: 246.90 mg/dL)Kidney (Creatinine 0.7), Liver, and Thyroid (TSH 1.28) functions are completely normal.CBC: Total WBC count is slightly low at 3,500 cumm.Vitamins: Borderline Vitamin B12 (178.9 pg/mL) and insufficient Vitamin D (26.7 ng/mL).Given her severe hyperglycemia, she needs an immediate medication adjustment. However, due to her low body mass, we want to completely avoid drugs that cause weight loss or digestive distress (like Metformin or SGLT2 inhibitors).Could you please advise if
