Immediate Management: Treat Hypoglycemia NOW

You must treat this hypoglycemia immediately with 15-20 grams of fast-acting carbohydrate, recheck glucose in 15 minutes, and repeat treatment if still low 1, 2, 3, 1. With a glucose of 42 mg/dL at 1300, this is clinically significant hypoglycemia requiring urgent intervention.

Acute Treatment Steps

Give 15-20 grams of glucose (glucose tablets preferred, or any carbohydrate containing glucose like juice, regular soda, or candy) 1, 2, 1
Recheck blood glucose in 15 minutes - if still <70 mg/dL, repeat the 15-20 gram dose 2, 3
Once glucose normalizes, consume a meal or substantial snack with protein and carbohydrate to prevent recurrence 1, 2
Have glucagon readily available for future episodes where oral intake isn't feasible 2, 3, 4

The glucose level of 42 mg/dL is well below the treatment threshold of 50-70 mg/dL and requires prompt action 1.

Critical Issue: STOP Jardiance Immediately

Discontinue Jardiance (empagliflozin) 25 mg immediately 5. This medication is creating multiple serious problems:

Why Jardiance Must Be Stopped

Not FDA-approved for type 1 diabetes - the drug label explicitly states "JARDIANCE is not for people with type 1 diabetes. It may increase their risk of diabetic ketoacidosis" 5
Severe renal impairment - with eGFR 33 mL/min/1.73 m², you are approaching the contraindication threshold. Jardiance is "not recommended for use to improve glycemic control in adults with type 2 diabetes mellitus with an eGFR less than 30 mL/min/1.73 m²" 5
Increased DKA risk in type 1 diabetes - research shows DKA rates of 3.3-4.3% with empagliflozin 10-25 mg doses in type 1 diabetes, though lower (0.8%) with 2.5 mg 6. The FDA issued specific warnings about euglycemic DKA with SGLT2 inhibitors in type 1 diabetes 3
Contributing to hypoglycemia - SGLT2 inhibitors cause glucose loss independent of insulin, which combined with your low appetite is driving these dangerous lows

Pump Settings Require Immediate Adjustment

Your Medtronic 780G settings need urgent modification to prevent recurrent hypoglycemia:

Specific Setting Changes Needed

Basal rate (currently 0.5 U/hr):

Reduce by 20-30% immediately to approximately 0.35-0.4 U/hr
With low appetite and reduced food intake, your basal insulin needs are lower 1, 7

Insulin-to-carbohydrate ratio (currently 5.5):

Increase to 6.5-7.0 (meaning less insulin per carb gram)
This is too aggressive given your recurrent hypoglycemia

Insulin sensitivity factor (currently 25):

Increase to 30-35 (meaning less correction insulin per mg/dL above target)
Current setting is causing over-correction

Active insulin time (currently 2 hours):

Consider increasing to 3 hours to reduce insulin stacking 7, 8
The 780G typically uses 2-8 hours; longer duration reduces aggressive corrections

Target glucose:

Temporarily raise from default to 120 mg/dL to create a safety buffer 3
After 2-3 weeks of hypoglycemia avoidance, can reassess lowering target

Address the Low Appetite and Renal Function

Your low appetite with advanced CKD (Stage 3B, eGFR 33) requires immediate attention:

Assess for uremia - with creatinine 2.35 (baseline 1.7), worsening renal function may be causing anorexia
Check for volume depletion - Jardiance causes volume contraction, which is particularly dangerous with CKD 8, 5
Evaluate for intercurrent illness - infection, gastroparesis, or other acute issues may be reducing intake 1
Consider nutritional support - small, frequent meals with consistent carbohydrate timing 1, 9

The combination of reduced food intake and unchanged insulin dosing is a classic setup for severe hypoglycemia 1, 10.

Hypoglycemia Unawareness Protocol

Given these severe lows (42 mg/dL), you may be developing hypoglycemia unawareness:

Strictly avoid ALL hypoglycemia for 2-3 weeks - this can partially restore awareness 2, 3
Raise glycemic targets temporarily - accept higher glucose readings (140-180 mg/dL) during this period 3
Increase CGM monitoring - the 780G's Guardian sensor should alert before severe lows
Set low glucose suspend threshold higher - use the pump's predictive low glucose suspend feature 11

Research shows that 2-3 weeks of scrupulous hypoglycemia avoidance can restore awareness in many patients 2.

Monitoring and Follow-up

Within 24-48 hours:

Verify pump setting changes are preventing lows
Confirm Jardiance discontinuation
Check for DKA risk (given recent SGLT2i use) - measure ketones if any symptoms 8, 5

Within 1 week:

Recheck renal function (creatinine, eGFR) off Jardiance
Assess volume status and blood pressure
Review CGM data for time in range and hypoglycemia patterns

Within 2-4 weeks:

Reassess glycemic targets once hypoglycemia risk is controlled
Consider gradual optimization of pump settings if glucose running high
Evaluate need for nephrology referral given declining renal function

Common Pitfalls to Avoid

Do not continue Jardiance "because it was helping glucose" - the risks far outweigh benefits in type 1 diabetes with your renal function 5
Do not make only small adjustments to pump settings - with glucose of 42 mg/dL, you need substantial reductions (20-30%) in insulin delivery 7, 10
Do not ignore the low appetite - this is a critical piece driving hypoglycemia and may signal worsening uremia or other serious issues 1
Do not resume aggressive glucose targets immediately - allow 2-3 weeks of higher targets to restore hypoglycemia awareness 2, 3
Do not assume the 780G algorithm will prevent all lows - while advanced hybrid closed-loop systems like the 780G significantly reduce hypoglycemia 12, 13, 14, they still require appropriate baseline settings and user input, especially with changing clinical circumstances like reduced food intake
