What Insulin Resistance Actually Means
Insulin resistance means that your cells (muscle, fat, and liver) don’t respond efficiently to insulin’s signal.
Normally, insulin acts like a key that opens the cell so glucose can move from the bloodstream into the cell to be used for energy.
With insulin resistance, the lock is rusty — insulin is present, but the signal doesn’t work well.
As a result:
-Glucose stays in the bloodstream longer
-More insulin is required to get the same glucose-lowering effect
Insulin Resistance vs. Type 1 Diabetes (Important Distinction)
Type 1 Diabetes
-The pancreas produces little to no insulin
-Insulin must be supplied externally (pump or injections)
-Primary issue = insulin deficiency
Insulin Resistance
-Insulin is present (endogenous or injected)
-Cells don’t respond properly
Primary issue = poor cellular response
👉 A Type 1 diabetic can absolutely have insulin resistance.
This is often called “double diabetes.”
What Insulin Resistance Looks Like in Type 1 Diabetes
For someone with Type 1, insulin resistance often shows up as:
-Needing higher insulin doses than expected
-Blood sugars that stay high despite insulin
-Delayed glucose lowering after boluses
-Higher basal needs without obvious dietary changes
-Increased post-meal spikes
-Difficulty bringing glucose down during illness, stress, or inflammation
-This is not a failure — it’s a physiological response.
Why Insulin Resistance Happens in Type 1 Diabetics
Common contributors include:
-🔥 Inflammation
-Chronic inflammation interferes with insulin signaling
-Genes like IL6 can amplify this effect
🧬 Genetics
-Variants affecting glucose transport, mitochondrial function, or methylation (like MTHFR) can reduce insulin sensitivity
🦠 Infection or Illness
-Flu, sinus infections, or chronic pathogens raise cortisol and cytokines
😰 Stress & Cortisol
-Stress hormones directly block insulin’s action
🧪 Oxidative Stress
-Mitochondrial inefficiency (ex: SOD2) reduces glucose uptake efficiency
🧈 Lipotoxicity
-High circulating fats + insulin resistance = poor glucose disposal
-Why This Matters (Especially for You)
For Type 1 diabetics, insulin resistance means:
-More insulin ≠ better control
The goal becomes improving cellular responsiveness, not just increasing insulin
This is why approaches that support:
-Inflammation balance
-Mitochondrial health
-Mineral status
-Timing of meals & insulin
-Nervous system regulation
can dramatically improve control without chasing numbers.
Key Takeaway (Simple + Honest)
-Insulin resistance is not about insulin availability — it’s about whether your cells are listening.
And for Type 1 diabetics, supporting cellular health is just as important as managing insulin delivery.
It really sucks being a type 1 diabetic. It really means training your mind and body to eat in a new way and changing your lifestyle.
