Your
sugar levels are significantly elevated — fasting 264 mg/dL and post-meal 374 mg/dL are well above the diabetic range. Please don't panic, but this needs medical evaluation promptly rather than waiting or trying home remedies.
You should get an
HbA1c and repeat laboratory glucose test to assess how long your sugars have been elevated and to confirm the diagnosis if required.
Since your levels are quite high, a doctor should also assess your
kidney function,
electrolytes, urine, blood pressure and other
diabetes-related risk factors and decide whether you need tablets, insulin, or another treatment based on your clinical condition.
If you have excessive thirst/urination, vomiting, abdominal pain, marked weakness, drowsiness/confusion, rapid/deep breathing or dehydration, please go to an emergency department immediately, as very high glucose can occasionally be associated with serious metabolic complications.
Next Steps
See a physician/diabetologist within 24–48 hours. Get:
HbA1c, fasting/venous plasma glucose, CBC, RFT/eGFR,
electrolytes, urine routine, urine ketones (especially if symptomatic),
lipid profile and
liver function tests. Further testing can be decided after examination.
Health Tips
Until reviewed, avoid sugary drinks, sweets and large amounts of refined carbohydrates. Stay adequately hydrated unless you have been advised to restrict fluids. Do not start insulin or
diabetes tablets on your own, because the appropriate treatment depends on your symptoms,
HbA1c, renal function and whether there is evidence of ketosis.
