Can type 2 diabetes actually be reversed?
For many people, yes — type 2 diabetes can be put into remission. That’s the part conventional care often doesn’t emphasize. Standard treatment tends to manage type 2 diabetes: track the numbers, add medication as it worsens, and accept a slow progression.
Functional medicine takes a different starting point. Type 2 diabetes is fundamentally a problem of insulin resistance — your cells stop responding properly to insulin, so blood sugar climbs. Insulin resistance is largely driven by diet, lifestyle, inflammation, and metabolic dysfunction, which means it can be reversed when you address those drivers directly.
At the Center of Functional Medicine in Westminster, CO, Dr. Glenn Harrison focuses on reversing the underlying metabolic dysfunction rather than simply medicating the symptom.
What’s the difference between managing and reversing diabetes?
Managing diabetes means controlling blood sugar with medication while the underlying insulin resistance stays in place — and often gets worse over time.
Reversing diabetes means restoring your body’s insulin sensitivity so blood sugar normalizes on its own, reducing or eliminating the need for medication. Reversal addresses the cause; management addresses the symptom.
Functional medicine aims for reversal whenever it’s achievable — always working in conjunction with your prescribing physician, who manages any medication changes.
What causes insulin resistance?
Type 2 diabetes doesn’t appear overnight. It builds for years through:
- Chronically elevated blood sugar and insulin from a diet high in refined carbs and sugar
- Excess visceral fat, which is metabolically active and inflammatory
- Chronic inflammation, which interferes with insulin signaling
- Poor sleep and chronic stress, which raise blood sugar via cortisol
- Gut dysfunction, which influences metabolism and inflammation
- Sedentary lifestyle, which reduces the muscle’s ability to use glucose
- Nutrient deficiencies involved in blood sugar regulation
A reversal protocol has to address these — not just push insulin harder.
What does a functional medicine diabetes reversal protocol look like?
A root-cause protocol is individualized, but it generally works across several pillars at once:
- Targeted nutrition. A blood-sugar-stabilizing way of eating — lower in refined carbs and sugar, rich in protein, healthy fats, and fiber — to reduce the insulin load and let the body heal.
- Restore insulin sensitivity. Strategically rebuilding the cells’ ability to respond to insulin through diet, movement, and metabolic support.
- Reduce inflammation. Identifying and removing the inflammatory triggers — including hidden gut issues and food sensitivities — that block insulin signaling.
- Improve sleep and stress. Because both directly raise blood sugar, fixing them is non-negotiable for reversal.
- Movement that builds metabolic health. Activity that helps muscles soak up glucose and improves insulin sensitivity.
- Targeted nutritional support. Replenishing the specific nutrients your body needs for healthy blood sugar regulation.
- Monitor and adjust. Tracking A1C, fasting glucose, and insulin over time, and coordinating medication reductions with your prescribing provider as your numbers improve.
What results can you expect?
When the root drivers are addressed, many people see meaningful drops in A1C and fasting glucose, reduced medication needs, weight loss, more stable energy, and fewer blood-sugar crashes. The timeline depends on how long diabetes has been present and how consistently the protocol is followed — but progress often shows up within the first few months.
This reflects the experience patients describe with Dr. Harrison: an approach that’s thorough, root-cause focused, and that gives them not just relief but the tools to maintain results long-term.
Frequently asked questions
Is reversing type 2 diabetes permanent?
It can be lasting — as long as the lifestyle and dietary changes that produced the reversal are maintained. Reversal puts the disease into remission; sustaining it requires sustaining the new habits.
Can I stop my diabetes medication?
Possibly, as your numbers improve — but never on your own. Functional medicine works alongside your prescribing physician, who manages all medication adjustments safely as your blood sugar normalizes.
How is this different from just “eat better and exercise”?
A functional medicine protocol is personalized to your root causes — your specific drivers of inflammation, your gut health, your stress and sleep patterns, your nutrient status — not generic advice. That precision is what makes reversal achievable.
What about pre-diabetes?
Pre-diabetes is the ideal time to intervene. Catching insulin resistance early makes reversal far easier and can stop the progression to full type 2 diabetes entirely.
Does functional medicine work for type 1 diabetes?
Type 1 diabetes is autoimmune and requires insulin, so it can’t be reversed the same way. However, functional medicine can support overall metabolic health and blood sugar stability alongside standard care.
