Yes, a blood sugar level dropping to 54 mg/dL yesterday and then shooting up to 433 mg/dL today is a serious concern — especially in an elderly person who is immobile, catheterized, and likely dealing with other health conditions. What You Should Do Immediately 1. Consult your doctor urgently or go to a hospital if the symptoms worsen (confusion, drowsiness, dehydration, abdominal pain). 2. Repeat blood sugar levels regularly (every 4–6 hours). 3. Check for signs of infection: fever, burning urination, increased catheter output, or foul smell. 4. Request urgent blood tests: • CBC • Urine routine/microscopy • HbA1c • Kidney function • CRP (if infection is suspected) ⸻ ✅ Immediate Management Tips • Ensure consistent nutrition — avoid long gaps in meals. • Keep glucose powder/juice handy in case of low sugar again. • If insulin is withheld, it must be under strict medical advice. In some cases, short-acting insulin may still be needed to bring 433 down safely. • Ensure hydration is maintained unless contraindicated (heart/kidney issues). ⸻ ⚠️ Important: Fluctuating sugar levels in elderly patients can be life-threatening. If your father is not under close observation (hospital or home care), and the sugar is at 433 mg/dL, he needs to be seen by a physician immediately.

Do consult doctor for physical examination once and have a follow up.
