I want to tell you about a patient I see all the time in my practice.
She wakes up at 6 a.m., reaches for her glucose meter before she’s even had a sip of water, and checks her blood sugar. The reading comes back at 128 mg/dL.
Immediately, she feels discouraged.
The night before, she had a healthy dinner. She skipped dessert. She didn’t snack before bed. In fact, she hasn’t eaten in over 11 hours. Yet somehow her blood sugar is still elevated.
Her first thought is, “What did I do wrong?”
And my answer is often the same:
You may not be doing anything wrong at all.
In many cases, the reason your fasting blood sugar stays high has very little to do with what you ate the night before. The real culprit may be an organ that’s been working all night long while you were asleep: your liver.
One of the biggest misconceptions I encounter is the belief that blood sugar only comes from food. While food certainly plays a major role, your body is actually capable of making and releasing glucose on its own. Your liver stores glucose and releases it when your body thinks it needs energy. This is a normal survival mechanism that has kept humans alive for thousands of years.
The problem occurs when that system becomes dysregulated.
If you have insulin resistance, prediabetes, type 2 diabetes, excess abdominal weight, fatty liver disease, or certain hormonal imbalances, your liver may release more glucose than your body actually needs. As a result, you can wake up with elevated blood sugar even though you haven’t eaten for hours.
In this video, I’ll explain exactly why this happens.
We’ll talk about the fascinating relationship between your liver, insulin, and hormones such as cortisol, growth hormone, and glucagon. I’ll show you how these hormones naturally rise in the early morning hours and can trigger your liver to release glucose into your bloodstream.
We’ll also discuss a phenomenon known as the Dawn Phenomenon, one of the most common reasons people experience high fasting blood sugar. If you’ve ever wondered why your glucose is higher at 6 a.m. than it was at bedtime, this explanation may finally help everything make sense.
You’ll learn:
✅ Why fasting blood sugar can remain elevated despite long periods without food ✅ How your liver produces and releases glucose overnight ✅ What insulin resistance does to this process ✅ The role of cortisol, growth hormone, and glucagon in morning blood sugar spikes ✅ How the Dawn Phenomenon affects people with prediabetes and diabetes ✅ Why a high fasting glucose doesn’t always mean you failed the day before ✅ Practical strategies that may help improve fasting blood sugar levels ✅ When it’s time to discuss persistent high morning glucose with your healthcare provider
Most importantly, I want you to understand that your fasting blood sugar is not simply a reflection of willpower. It is the result of a complex interaction between your liver, your hormones, your insulin sensitivity, your sleep, your stress levels, and your overall metabolic health.
Once you understand what’s happening behind the scenes, you can stop guessing and start addressing the real causes.
If you’ve been frustrated by stubbornly high fasting blood sugar despite eating well, exercising, and following your treatment plan, this video is for you.
I’d love to hear from you in the comments: What is your fasting blood sugar when you first wake up? Have you noticed it staying high despite fasting overnight?

I want to tell you about a patient that I see almost every single week. She wakes up at 6 a.m.,
right, checks her blood sugar before she's even had a sip of water and it's 128 milligrams per
deciliter. She hasn't eaten since like seven o'clock the night before. 11 hours of fasting
and her blood sugars are still high and it keeps going up if she doesn't do anything about it in
So she looks at that number and she feels defeated, right? She thinks she's failing.
She thinks something is permanently broken inside her body. But here's what I tell her
and here's what I want to tell you today. Nothing is broken. Your body is actually
doing exactly what it has been trained to do. The problem is it's been trained the wrong way
and today we are going to change that. I'm Dr. Ahmet Ergin from SugarMD as you know from
sugarmds.com and I operate as a physician at Diabetes Thyroid and Hormone Center of the
Treasure Coast and I'm going to walk you through exactly why your fasting sugar is not coming down
and what is actually happening inside your body while you sleep. Let's start with the root of
almost everything, right? Insulin resistance. Imagine your cells have a front door. Insulin
is the key to that door. Every time you eat, especially carbohydrates, your pancreas sends
out insulin keys to unlock your cells and let glucose in for energy. Simple system,
beautiful, really nice. But here's what happens after years of high carb diet,
processed foods, excess sugar, which some people call it American diet, your cells get so bombarded
with insulin keys day after day, meal after meal, that they start to ignore the knocking,
they stop responding, they become rusty and the door won't open. So your pancreas basically panics,
it makes more keys, more insulin, right? Or louder knocking, more insulin, whatever it takes
until eventually the whole system starts breaking apart. And your liver, you know, this is where
the critical part is actually, your liver is supposed to release a small, small controlled
amount of glucose overnight to keep your brain alive while you sleep, that's it. But when your
liver becomes insulin resistant, it doesn't get the signal to slow down. It just keeps pouring
glucose into your bloodstream all night long, full speed. That's why you wake up at 128 even after
fasting for 11 hours. It is not what you ate, sometimes it is, but it may not be, but it is
what your liver is actually doing while you're sleeping. Layer on top of that, let's talk about
visceral fat. This is not the fat you can see or pinch. This is the fat wrapped around your organs.
You can be skinny and you can still be fat inside. We call them skinny fats actually.
Now your liver, your pancreas, deep inside your abdomen. And this fat is not passive,
it is very aggressive. It is actively releasing inflammatory chemicals into your bloodstream,
chemicals that go straight to your liver and muscle cells and block insulin from working for you.
And here's what makes it a vicious cycle as well. The high glucose, high blood sugar,
causes more fat storage. More visceral fat causes more insulin resistance. More insulin resistance
causes higher blood sugar. Round and round it goes and your fasting numbers just keep sitting there,
stubborn, unmoved. So what breaks the cycle? Dropping insulin levels low enough
and long enough for your body to start burning that fat. That means cutting that refined
carbohydrates, not just reducing them, but totally eliminating them. It also means intermittent
fasting. It means giving your body the metabolic breathing room it desperately needs. Here's the
third piece of the puzzle. And honestly, most people never connect this dot. You're not moving
enough. I'm sorry. Inside your cells, there are these incredible little glucose transporters
called GLUT4. And here's the remarkable thing about them. When your muscles contract,
when you walk, when you squat, when you lift something heavy, those transporters activate
and pull glucose directly out of your bloodstream without needing insulin at all. No insulin is
needed. Your muscles are the single greatest glucose disposal system your body has,
and it does not need insulin. Most people are leaving that system completely at idle,
or they take a 10-minute walk and call it a day. But even a 20-minute walk after dinner
can drop your blood sugar by 30 to 50 points. Well, that's not a small thing. That is more than
some medications do. And when you exercise consistently, increase the intensity,
especially resistance training combined with cardio, you deplete your muscle glycogen stores,
and your muscles stay hungry for glucose throughout the night and into that morning.
So the exercise you do this morning can affect your blood sugar the following morning,
right? That is what's going to change your fasting. The patients I see with the highest,
most stubborn fasting blood sugars are almost always sedentary. Sometimes they won't accept
that, but their significant other will come and they'll just break the news.
Well, that's not a coincidence. And then there's the one that surprises everyone, right?
And most people don't even know that they are doing this one, right? They think everything
is fine with their sleep, but it's not. Sleep, right? So picture this. It is 3 a.m.,
you're tossing and turning. Maybe your partner is snoring. Maybe you are staring at the ceiling
with a wasting mind. Meanwhile, inside your body, your cortisol is spiking. Now, your cortisol is
your stress hormone, remember? And one of its primary jobs is to raise the blood sugar. It
tells your liver to dump glucose because biologically, stress means dandruff. Dandruff
means you need energy. You need energy is glucose. Give them glucose, right?
Just one single night of poor sleep, four to five hours, most people sleep like that,
reduces your insulin sensitivity by up to 25%, just one night. Imagine what months and years
of poor sleep is doing to your fasting numbers every single morning. And if you snore heavily,
if you wake up exhausted, if you get up multiple times to use the bathroom at night,
please, please get tested for sleep apnea. Every time you stop breathing,
your cortisol surges. That can happen sometimes over a hundred times in a person's body.
It is one of the most underdiagnosed drivers of insulin resistance I see in my clinic.
People resist to get this test done, but once they're done, they love it. They feel so much
better. Seven to nine hours of quality sleep is not a luxury for a doctor. It is your medicine.
Now, like I said, lifestyle is the foundation, but I need to be clear about that. Always,
you cannot supplement your weight out of a broken lifestyle. Yes, a lot of you are
taking sugar MD-Gluxion, sugar MD-Berberine. Your numbers are getting better, but that doesn't mean
that you need to ignore the lifestyle factors we are discussing in every video.
Now, sometimes the body needs additional support, right? It does. Sometimes you need medication,
sometimes you need supplements, but I'm going to tell you something new though. I know a lot of
you are on Gluxion, but what we did is we went back to the formulation and we sourced it from
a top-notch facility, strengthened it, tested it, and it works a lot more, a lot more potent
and more precisely targeted at the exact mechanisms we just talked about.
It works on liver glucose output, cellular signaling, insulin signaling,
the inflammatory pathways that drive the insulin resistance. Obviously, I have had patients stuck
at a fasting blood sugar of 134 months doing everything right, and then sometimes they're
like, you know what, let's try the Gluxion and see what the numbers do, and finally it starts moving.
Sometimes you need that push. Sometimes you need that powerful one. So,
please visit SugarMDs.com to check your options, and if you're on diabetes medication, definitely
work with your doctor because, you know, if you're on insulin, etc., you add these powerful supplements
like SugarMD Gluxion, you may need to adjust your insulin down a little bit. Now, that is a good
problem, right? Now, so, to the patient waking up at 128 every morning feeling defeated, and to you
watching this right now, I'll tell you this. Nothing is permanently broken. Your liver is
overreleasing glucose because it is insulin resistant. Your visceral fat is feeding the
inflammation. Your muscles aren't being used to their potential, and your sleep may be silently
sabotaging everything else you're doing. So, please fix those four things, and your fasting blood sugar
should follow. I'm Dr. Ergin, your Sugar MD. I will see you in the next video.
