Is hypoglycemia a prediabetes warning?

A prediabetes warning can be characterized by low blood sugar symptoms like fatigue, weakness, tiredness, and more. This phenomenon, despite how common it is, is not normal, nor is it healthy. It’s the classic sign of what is known as reactive hypoglycemia and an early symptom of the prediabetes-related condition known as insulin resistance.

Refined Carbs Can Cause Wild Mood Swings

If you eat a meal loaded with sugar and refined carbs, you will experience wild swings in blood sugar that make you feel tired, anxious, irritable, and hungry for more quickly absorbed sugars. When you repeat this process day in and day out, eating a diet full of empty calories, refined carbohydrates (bread, pasta, rice, potatoes), sugars, and sweetened beverages (sodas, juices, sports drinks), your cells start to become resistant or numb to insulin. You end up needing more and more insulin to keep your blood sugars down. This is insulin resistance, a pre-diabetic condition that has become an epidemic.

What is Reactive Hypoglycemia and is it a Prediabetes Warning?

What is the first sign of hypoglycemia? Reactive hypoglycemia is characterized by low blood sugar symptoms like fatigue, weakness, tiredness, dizziness, sweating, shakiness, palpitations, anxiety, nausea, a sensation of hunger, and difficulty with concentration which occur after eating an abundance of sugar or refined carbs. These reactive hypoglycemia symptoms occur in the early stages of insulin resistance.

Take a typical breakfast these days: swigging a large sweetened coffee drink and grabbing something from the Starbucks pastry case will give you a big energy surge as your sugar and insulin levels spike. What follows, however, are inevitable sugar crash symptoms as your blood sugar plummets.  With this comes the low blood sugar fatigue.

Insulin Levels May Be the First Sign That Something is Wrong

While reactive hypoglycemia is typically the first symptom, the first sign your doctor could see, if he or she checked, would be high insulin levels. High insulin causes your body to create more belly fat, more inflammation, and more oxidative stress while you lose muscle. The downstream effects of this, besides an expanding waistline and fatigue, are scary. High insulin levels and insulin resistance are linked to high blood pressure, high cholesterol, high triglycerides, low HDL, low sex drive, infertility, depression, heart disease, stroke, dementia, cancer—all the common diseases of aging.

Hypoglycemia vs Diabetes

Does hypoglycemia lead to diabetes? You cross the line to diabetes when your cells eventually become so resistant to insulin that it can’t do its job. This causes your blood sugar to stay up and your pancreas to go into overdrive trying to produce enough insulin to fight against your high blood sugar and resistant cells. But given that insulin resistance itself is linked to all the above-mentioned problems, it’s foolish to wait until you receive a diagnosis of diabetes to start breaking the cycle.

How to Stop the Cycle

You can start today. You don’t need a pill to help stop symptoms of reactive hypoglycemia, lower your insulin, and reverse insulin resistance and prediabetes. Cut the white flour, sugar, and corn syrup out of your diet. Replace these empty calories with nutrient-packed whole grains, lean proteins, beans, nuts, fruits, veggies, and healthy fats, and see what a difference this makes in terms of your energy levels and your low blood sugar symptoms.

  • Every time someone mentions fatigue it’s always some life threaten disease. Not like it used to be anemia, or not enough rest. I hope our nation can get back on track without all this negative imputes on various issues. We as American citizens is so tired of always getting bad information from our so-called health experts. Some have reason to believe these experts are contributors to the bad health results which indicate why the negative output is expressed. Most citizens know where most health diseases are originated, from medicines. Many prescribed medications induce the diseases doctors are treating. Which is sad so many is dying daily from diabetes, cancer and other medicine induced related diseases, shame on our health care system. Another sad thing, you think the American people don’t know this, they do.

  • This article is not crap. I am experiencing this myself after years of a high carb diet with no exercise. You start to get light-headed / giddy and extremely sleeply after a meal that is high in sugar/carbs, especially refined ones, and previous you don’t get this at all. I have already reduce my carb intake but still continue even after eating wholegrains. Going to start exercising high intensity asap.

  • To RJ
    If you were not experiencing fatigue after eating a meal High in refined sugar and simple carbs that’s when your body wasn’t working correctly.

  • Hello
    I have been diabetic for some time and I followed a wide variety of treatments, I have even combined with different medicinal plants without clear results. My health was deteriorating more and more. But thanks to a method that I found on the internet to achieve the results i wanted,i knew from the beginning that this could help me, and I began to follow the method from Dr Alhaji Shanu and the results were wonderful: I recommend you to get in contact with him via
    Whatsapp or call: +2348158856436.

  • Cut Out Flour and sugar and products made from flour and sugar. Drs and Govt causing bad health with bad nutritional information. High fat is good. Nuts good butter good full fat milk good eggs good. Low fat is rubbish as is sugar and flour.

  • To: dvanilla you are ignorant your comment is based on assumptions not fact, most diseases are not caused by medications diseases are caused by enviroments, bacteria, and in most cases all the processed foods and chemical ladened products we use today. If we as people went back to natural remedies and eating healthier and exercises more we as a society wouldn’t be where we are today. Instead of opening your mouth to something you know nothing about do your research first.

  • Tnx for all inf. I’m suffering from hypoglycemia, what’s best for pre intense (CrossFit) workout, or run, early morning when I don’t have much time for a meal. And is energy gels for running bad?
    I’m struggling with blurriness post run and headache.


  • Runner….eat a few nuts, which requires no work before a run, some electrolyte water before and after an intense run? Headache after running could be dehydration?
