Hypoglycemia Symptoms

One of the classic signs of Adrenal Fatigue are hypoglycemia symptoms. Traditionally hypoglycemia is a medical term for a state produced by a lower than normal level of blood sugar.

Unfortunately, no single glucose value alone satisfactorily gauges all people because many variables are involved. While there are no disagreements as to the normal range of blood sugar (90-110 mg/dl), debate continues as to what degree of hypoglycemia warrants medical evaluation and treatment, or can cause harm.

Throughout the 24-hour cycle of a day, blood plasma glucose levels of healthy people are generally maintained between 72 and 144 mg/dL (4-8 mmol/L) while 60 or 70 mg/dL (3.3 or 3.9 mmol/L) is commonly cited as the lower limit of normal glucose.

Many healthy people can occasionally have glucose levels in the hypoglycemic range without hypoglycemia symptoms of disease. This makes hypoglycemia a difficult clinical state to establish in the first place. The problem is further compounded in those with Adrenal Fatigue.

In adrenal fatigue, the hypoglycemia experience is more often than not sub-clinical. This means that the person has clinical hypoglycemia symptoms even though the blood plasma level is invariably above 60-70 mg/dl. Their fasting serum blood sugar and glucose tolerance tests are usually normal. Conventional doctors not aware of the adrenal influence will miss this.

The diagram below shows how Adrenal Fatigue contributes to hypoglycemia symptoms. Compared to a normal person or even one with compromised insulin control, those with Adrenal Fatigue tend to have hypoglycemia symptoms even though the serum blood sugar may be within the normal range. This is clinically evident. After a meal, those with advanced Adrenal Fatigue tend to have a faster dip in serum blood sugar below the Hypoglycemic Symptoms Threshold (HSL) level compared to normal. This triggers symptoms of hypoglycemia such as irritability and fatigue. The more advanced the Adrenal Fatigue, the more the blood sugar curve is shifted towards the left. As a result, the time between completion of a meal to the onset of hypoglycemia symptoms is shortened.

Sugar and Adrenal Fatigue

For this reason, it is common for those with Stage 3 and beyond Adrenal Fatigue to require sugar replenishment every 2-3 hours. A small snack usually suffices. In fact, as Adrenal Fatigue recovers, this period lengthens. Those with Stage 2 Adrenal Fatigue can go 4-6 hours without food and not have hypoglycemia symptoms and hunger.  Many in Stage 1 can skip a meal and have no symptoms at all.

Our body needs a continuous supply of energy to maintain homeostasis throughout the day. Cellular energy demand is met by intake of food, which is then converted into sugar. When this demand is not being met, as in Adrenal Fatigue, the body will turn to existing protein and fat as resources of energy. This pathway is not as efficient but, nevertheless is put on overdrive in order to provide the energy required. Without adequate cortisol levels to elevate blood sugar levels by facilitating the conversion of glycogen, fats, and proteins to new glucose supplies, this increased demand is difficult or impossible to meet. Irregular blood sugar patterns with hypoglycemia are common as the body tries to kick start the process whenever it detects a low blood sugar level. This leads to a variety of symptoms.

Hypoglycemia symptoms include hunger, nausea, headache, rage, lethargy, daydreams, confusion, amnesia, dizziness, fatigue, irritability, anxiety, jittery feelings, adrenaline rush, elevated heart rate, memory loss, and in severe cases, fainting, coma, and seizures.

Key hormones regulating blood sugar in the body include insulin, cortisol, and growth hormone. Conditions associated with Adrenal Fatigue that might also play a part in sugar regulation include PCOS, metabolic syndrome, drug effects, adrenal insufficiency, and diabetes. In the absence of other medical reasons, one must consider Adrenal Fatigue as a cause.

Acute hypoglycemia can easily be temporarily reversed by taking 10-20 grams of carbohydrate (3-4 ounces of orange, apple or grape juice). While this can be overcome with a sugar fix consisting of an instant load of sugary drink or food such as coffee or soda, this is a quick solution emergency remedy only. Usually symptoms go away immediately, but return after 1-2 hours. Reactivation and restoration of normal cell function require extra amounts of energy beyond what is normally required for maintenance of normal energy burn. With each hypoglycemic episode, more cells are damaged. Thus, the body reaches a new low with each insult of hypoglycemia. If this happens at the same time as demand for glucose increases, the stage becomes set for an adrenal crisis. With each plunge, the Adrenal Fatigue increases and hypoglycemia worsens. By the end of the day, the person may feel nearly exhausted without having done anything. Low blood sugar times are most likely to occur at around 10:00 a.m., 2:00 p.m., and from 3-4:00 p.m.

    How do meal replacements fair when dealing with hypoglycemia ? Some times using them is just easier then cooking.

  • Christine says:

    My son is 5 yrs old and has recently had a blood test to test for diabetes but his level came back as normal at 4.5 mmol/L. When my son gets hungry he either says he is tired and lyes on the floor or his bed doing nothing (he doesnt actually fall asleep just kind of goes into his own world) or becomes very irritable, crying and throwing a huge tantrum often over something very minor. Once we manage to get some food into him he is like a different kid – well he becomes his normal self again. It is a marked difference to us. Sometimes he says he cant eat even though I know he is hungry as he says his tummy hurts. On these occassions I give him a tiny bit of juice and then I offer him the same food as before and he will have no problem eating it. Hypoglycemia runs in my family but it seems he does not have that as his blood test said he was normal. So the Drs are saying it is behavioural. Do you have any ideas? My gut is that it is not behavioural that there is something going on, but the medical stuff says otherwise.

    Is hypoglycemia reversible?

    • Dr.Lam says:

      In the setting of AFS, yes in most cases if properly addressed. It can also get worse if not approached properly.

  • Phil says:

    I believe i do have an acute form of hypoglycemia from reading your article. I will try the carbohydrates with juice for a quick fix, but how can i decrease any hypoglycemic episodes?

    • Dorine Lam RDN says:

      In order for you hypoglycemia to improve, you need to look at the underlying issue, what is causing the hypoglycemia. If the underlying issue is Adrenal Fatigue Syndrome, then you need to improve your adrenal glands first.

  • Colleen says:

    I’ve heard nuts are helpful snacks for those suffering from hypoglycemia. Unfortunately, I am allergic to nuts. Are there alternative snacks that you recommend?

    • Dorine Lam RDN says:

      You need some sort of protein and fats in your snack. You can even use the food you have from your previous meals. Eggs and cheese, meat are good alternative.

    My 20 year oldaughter almost always feels hungry after she eats. She eats a lot of simple carbs so I think she isn’t balancing her meals. She was still concerned so she saw her doctor today. They checked her blood pressure while laying down, sitting and standing and they were all about the same. So she had blood drawn to check glucose, anemia and thyroid and they were all normal. She is going to focus on diet changes, if that doesn’t seem to help any other suggestions? Thank you.

    • Dr.Lam says:

      Loa blood pressure can be a sign of adrenal fatigue. But we dont want to jump to conclusion until everything else has been ruled out.

      • Karla says:

        Her BP was 102/60. Do you consider that low?

        • Karla says:

          Also all blood work came back within normal limits. She was advised to stay hydrated. No further work up. I failed to mention when she gets hungry after just eating she get tired and nauseous like she is about to faint. If she eats then she feels better.

        • Dr.Lam says:

          There is really no formal definition of low blood pressure. Most conventional docs would want you to be able to stand up and not feeling dizzy, and have no problem with urination. ( remember that the blood pressure needs to be at a certain level for uring stream to form). Generally speaking 102/60 alone is not considered low unless there are other symptoms.

  • Daniel says:

    I’m always hungry. If I don’t eat every 2 hours I get dizzy, nausea, heart palpitations and just feel like crap all around. Now I know why… Now time help my body instead of hurting it by ignoring it’s signals. Thank you Dr. Lam.

    • Dr.Lam says:

      Reactive hypoglycemia can be a problem and symptoms are similar to what you mentioned. The key is to understand that the body’s underlying metabolism is not well. So you need to focus on that. Click NeuroEndoMetabolic Symptoms of Stress for more information.

        Thank you so much for this wonderful comprehensive article. Iv been searching for this qnswer for months. I was literaaly killing myself with stress over the past three years and started hving these hypoglycaemia episodes. I stopped the bus in January and thought everything would get better but i hv crazy episodes of hypoglycaemia and was terrified it was a sign of diabetes. Iv asked many natural practitioners but not one has adequately been able to explain my symptoms…they mention adrenal fatigue but dont actually give this explanation. I now know that Im on the right path and fully understand mow. Thank you so much.

  • Becky says:

    I feel as though my blood sugar drops even right after I eat sometimes, and my vision blurs badly. This hasn’t shown up on tests as hypoglycemia or diabetes. I’m pretty sure it is adrenal fatigue. I’m quite ill but tests are “normal”. I had to have an oopherectomy at a young age and now am 60. Of course i had to be on estrogen. Can estrogen replacement cause hypoglycemia ? Or worsen my adrenal fatigue? I have cut the dose a good bit. I seem to be more and more sensitive to estrogen yet when I try to stop totally it is very dangerous with blood pressure spikes.

    • Dr.Lam says:

      If you have reactive hypoglycemia, your blood sugar would be normal while you are symptomatic. Estrogen is usually not related to this type of hypoglycemia, but AFS is. The complexity arises when AFS is associated with estrogen dominance, and that in turn can cause metabolic imbalances. Something is not right. I dont have enough details to have a handle on what is going on based on your description.

    I quit using tobacco and two weeks after I crashed and have still not recovered. Constant thyroid symptoms and severe anxiety and panic attacks and my body has reverted to basic form. MY stomach does not digest food almost at all. Need your help

  • Emily says:

    Are there any supps that I can take to prevent my blood sugar from dropping? I feel like my sugar tends to drop in my sleep and wakes me in the middle of the night.

    • Dr. Lam says:

      Chromium is a supplement that have sugar balancing properties. Eating some snack before bedtime is also a good strategy.
