Reversing Type 2 Diabetes and Pre-Diabetes in Westminster, Colorado: A Functional Medicine Approach
If you live in Westminster, Colorado or anywhere across the north Denver metro — Arvada, Broomfield, Thornton, Northglenn, or Federal Heights — and you’ve recently been told your blood sugar is too high, you are not alone. More than 1 in 3 American adults now has pre-diabetes, and the majority don’t know it. The good news: type 2 diabetes and pre-diabetes are not life sentences. They are metabolic conditions, and metabolic conditions can be reversed when you address the underlying cause instead of only chasing the number on the glucose meter.
At Dr. Harrison’s Center of Functional Medicine in Westminster, CO, we help patients across Colorado’s Front Range identify why their blood sugar is rising and build a personalized plan to bring it back into a healthy range — often without lifelong medication.
What Is Pre-Diabetes, and Why Does It Matter?
Pre-diabetes is the stage where your fasting blood sugar (100–125 mg/dL) or your A1C (5.7%–6.4%) is higher than normal but not yet high enough to be classified as type 2 diabetes. It is your body waving a red flag. Without intervention, roughly 70% of people with pre-diabetes will go on to develop full type 2 diabetes, which raises the risk of heart disease, kidney failure, neuropathy, vision loss, and stroke.
The conventional approach is usually “watch and wait” until the numbers cross the diabetes threshold, then prescribe metformin. The functional medicine approach is fundamentally different: we treat pre-diabetes as the warning it actually is, and we work to reverse it before it progresses.
Why Conventional Diabetes Care Often Falls Short
Standard diabetes management focuses on lowering blood sugar with medication. That’s important, but it doesn’t answer the more important question: why is the blood sugar elevated in the first place? In nearly every case of type 2 diabetes, the root cause is insulin resistance — your cells have stopped responding properly to insulin, so your pancreas pumps out more and more of it until it can’t keep up.
Insulin resistance is driven by a combination of factors that medication alone cannot fix:
- Chronic inflammation
- Poor gut health and microbiome imbalance
- Hormonal imbalances (thyroid, cortisol, sex hormones)
- Nutrient deficiencies (magnesium, chromium, vitamin D, B vitamins)
- Hidden food sensitivities
- Sleep disruption and chronic stress
- Toxin exposure and impaired liver detoxification
If you only treat the blood sugar number, you leave every one of these drivers in place. That is why so many diabetic patients see their medication doses increase year after year rather than decrease.
The Functional Medicine Approach to Diabetes in Westminster, CO
At Dr. Harrison’s Center of Functional Medicine, we use advanced lab testing and a whole-person evaluation to map out exactly what is driving your insulin resistance. Our process typically includes:
1. Comprehensive Metabolic Lab Testing. We go far beyond a standard A1C and fasting glucose. We look at fasting insulin, HOMA-IR (insulin resistance score), inflammatory markers like hs-CRP, a full thyroid panel, vitamin D, hormone levels, and often a comprehensive stool analysis to assess gut health.
2. Identifying the Root Cause. Two patients with the same A1C can have completely different underlying drivers. One may have a thyroid issue slowing metabolism, another may have gut dysbiosis fueling inflammation, another may be dealing with chronic cortisol elevation from stress. The treatment plan has to match the cause.
3. A Personalized Nutrition Protocol. There is no single “diabetic diet” that works for everyone. We build a nutrition plan around your labs, food sensitivities, lifestyle, and goals — focused on stabilizing blood sugar, lowering inflammation, and rebuilding metabolic flexibility.
4. Targeted Supplementation. Specific nutrients — magnesium glycinate, berberine, alpha-lipoic acid, chromium, inositol, and others — have well-documented effects on insulin sensitivity when used appropriately.
5. Lifestyle and Movement Coaching. Sleep, stress, and the right kind of movement (especially resistance training and post-meal walking) can move blood sugar more powerfully than most medications.
6. Ongoing Monitoring. We retest, adjust, and coach until your numbers — and the way you feel — reflect real, lasting change.
Who We Help
Patients come to our Westminster clinic from across the Denver metro area looking for answers when conventional care has only offered prescriptions. We commonly work with people who:
- Have been told they are “pre-diabetic” and want to prevent progression
- Have type 2 diabetes and want to reduce or eliminate their medication safely
- Have been struggling with weight gain, fatigue, brain fog, or sugar cravings alongside high blood sugar
- Have a family history of diabetes and want to get ahead of it
- Have tried conventional approaches and are not seeing their A1C improve
Frequently Asked Questions About Diabetes and Functional Medicine
Can type 2 diabetes really be reversed? Yes. Type 2 diabetes is driven by insulin resistance, and insulin resistance can be improved or fully reversed through targeted nutrition, weight loss, exercise, sleep, stress management, and addressing root causes like inflammation and gut health. Many of our patients at Dr. Harrison’s Center of Functional Medicine in Westminster, CO have reduced or eliminated their diabetes medications under medical supervision.
Where can I find a functional medicine doctor for diabetes near Westminster, Colorado? Dr. Glenn Harrison’s Center of Functional Medicine is located at 9035 Wadsworth Pkwy #3300 in Westminster, CO 80021, and serves patients throughout the north Denver metro including Arvada, Broomfield, Thornton, Northglenn, and Federal Heights. You can call 720-449-6217 or book a free 15-minute consultation online.
What is the difference between functional medicine and conventional diabetes care? Conventional diabetes care typically focuses on managing blood sugar with medications like metformin or insulin. Functional medicine looks for the underlying cause of insulin resistance — such as inflammation, gut health issues, hormonal imbalance, or nutrient deficiencies — and addresses those root causes through personalized nutrition, lifestyle changes, and targeted supplementation, with the goal of reversing the condition rather than only managing it.
What are the early warning signs of pre-diabetes? Common early signs of pre-diabetes include increased thirst, frequent urination, increased hunger, unexplained fatigue, blurred vision, slow-healing cuts, frequent infections, numbness or tingling in the hands or feet, darkened patches of skin around the neck or armpits, and difficulty losing weight despite effort. Many people have no obvious symptoms at all, which is why blood testing is essential.
What blood tests are best for detecting insulin resistance? The most useful tests for detecting insulin resistance go beyond fasting glucose and A1C. They include fasting insulin, HOMA-IR (a calculated insulin resistance score), a 2-hour glucose tolerance test, hs-CRP for inflammation, triglyceride-to-HDL ratio, and a full thyroid panel. At our Westminster clinic, we use these markers to detect insulin resistance years before standard tests would flag a problem.
Is pre-diabetes reversible without medication? In most cases, yes. Pre-diabetes responds very well to lifestyle and nutritional intervention, especially when started early. Studies show that targeted diet changes, regular movement, weight loss, and improved sleep can return blood sugar to normal in the majority of cases — often without the need for prescription medication.
How long does it take to lower A1C with functional medicine? A1C reflects an average of your blood sugar over roughly the previous three months, so meaningful changes typically appear within 8 to 12 weeks of starting a personalized functional medicine plan. Many of our patients see significant improvements in fasting glucose, energy, and weight within the first few weeks, with full A1C improvements following over the next several months.
Does insurance cover functional medicine for diabetes? Functional medicine consultations and protocols are typically not billed through insurance, which allows us to spend significantly more time with each patient and design highly personalized treatment plans. Many patients are able to use HSA or FSA funds. We’re happy to discuss pricing and options during your free 15-minute consultation.
What foods should I avoid if I have pre-diabetes or type 2 diabetes? The biggest contributors to high blood sugar are refined sugars, sugar-sweetened beverages, refined grains and flours, ultra-processed snack foods, and industrial seed oils. Personalized testing often reveals additional individual food sensitivities — such as gluten or dairy — that can drive inflammation and worsen insulin resistance for specific patients.
Can stress really raise blood sugar? Yes. Chronic stress raises cortisol, which signals your liver to release glucose into the bloodstream and makes your cells more resistant to insulin. This is why two people can eat the same meal and have very different blood sugar responses. Stress management is a core part of any effective diabetes reversal program.
