Does anyone have, or know much about, exercise-induced hypoglycemia? I've been researching it because I believe I have this, and am looking for anyone else that struggles with it. All my labs came back perfect from my doctor. Here's what's happening, in a nutshell:
A few times, during walking for about 20 minutes, I have gotten very fatigued all of a sudden, vision is blurry, hands and legs start shaking a bit, slight headache only in front of my head, and I'm all of a sudden hungry. I eat, or have something sweet, like a lollipop today that I thankfully had in my purse, and I start to feel better. I come home and eat and feel even better. Then I get extremely tired and have to take a nap. Wake up an hour or so later... I'm fine and feel like I can go run a marathon. (but afraid to... lol).
Has this happened to you or anyone else you know? Or has anyone heard of this happening? I've read about and it's something that can and does happen, due to sugar crashes during exercise in some people. And, no, I'm not diabetic, and have no medical issues whatsoever. All my labs came back absolutely perfect, including EKG.

Have you asked your DR about this?
That who you need to talk to

I'm quite familiar with hypoglycemia as it was an important part of pilot training in the Air Force. It frequently results in fatal crashes. The classic case is a "fighter pilot's breakfast" of a Coke and a candy bar. A glass of juice and an energy bar can have the same effect. So can any type of smoothie. The sugar lasts just long enough to get through the preflight briefing, pre-flight and into a critical phase of flight. Going unconscious can be instantaneous and without warning. I had it happen to a student one time, and it looked like he had an epileptic fit.
My first suggestion is if you feel dizzy sit or preferably lay down right away so you don't injure yourself in the fall. If it's hypoglycemia, a handful of raisins and peanuts should give almost instantaneous recovery for long enough to quickly get to a real meal heavy on carbs.
The concern is the dizziness may have a different cause.
A series of blood tests may help discover the cause. The first thing to rule out is a heart attack. A high level of troponin will test for this without exception. It's a protein that's released during heart attacks. Another thing to check for is any sort of infection. This will be indicated by a high white blood cell count. There are other tests to check for specific types of white blood cells that indicate where the infection is.
You could be having a Transient Ischemic Attack (TIA), which is a mini-stroke. You can test for this by closing your eyes after the dizzy spell passes and touching your nose and ears with your eyes closed. Squeeze your opposite wrists with your hands and see if one hand is weak. While laying down, press the top of your opposite foot with the opposite foot. Look for weakness or numbness. This will pass generally pass quickly. Most people have them starting at about age 50. It can be earlier. They lead to cognitive disorders later in life. If you think you are having a stroke, it's time to call an ambulance. Minutes are critical.
Your symptoms are a bit more indicative of hypoxia than hypoglycemia. The difference is the headache. A blood test showing the red blood cell count will test for anemia. This may simply be a poor diet, or it could be a sign of minor internal bleeding. At your age, a uterine cyst is a possible cause.
You may simply be constipated. About 95% of Americans are. If you are on a high fat, low-carb diet, you are almost certainly constipated. You may have simply been having trouble moving fecal matter through your large intestine. Pressing gently on the large intestine starting on the right side below the ribs and moving to the left can help this. So can laying on your left side. The reason this can cause dizziness is the colon demands more blood, and it will take it away from other areas of the body. It's similar to standing up too quickly for some people.
It's time for that free complete annual physical most insurance plans offer. They will likely find something the doctor will want to treat with drugs. These only mask symptoms and don't take away the cause. The cause is a dysfunctional diet. If you are interested, I can go into a little more depth on diet.

I did have a doctor's appointment on Thursday. That's how I know my bloodwork labs were all fine and my EKG was fine, as well, as I put in my post. She has no explanation, because I'm a totally healthy person as far as she can see. The only thing she told me to do was to stay away from concentrated sweets and stay out of the heat while walking or exercising. (which I don't do anyway)

Yep, did this.

As I mentioned in my original post, I already had a series of blood tests and an EKG. The appointment with my doctor showed nothing this past week.

Nope. Totally healthy heart. normal EKG.

Actually, headache IS an indicator of low blood sugar. And again, my blood test for this was normal. No uterine cysts.

No constipation. I eat plenty of fibrous foods.

I only take Zoloft for depression and anxiety. And Advil for pain or fever. I'm not a fan of meds the way it is. LOL

Thanks for responding. Keep in mind the process of discovering the cause is something like a Sherlock Holmes novel. I'll certainly make incorrect assumptions. Our goal is to narrow it down. I'm trying to stick to exactly what you said.
I don't eat this type of breakfast. I usually eat something high in protein and simple carbs about an hour or so prior to walking or exercising. I know what hypoglycemia can do, and what it is, but I'm asking about EXERCISE-INDUCED hypoglycemia.
This is a two-part answer. Simple carbs are digested quickly. They can give a quick burst of energy, but they give nothing for the long term. Protein doesn't give energy except in specific situations for a person completely new to exercise.
You may notice your heart rate climbs sometime during the first 20 minutes of walking and then declines. This is likely an indication you are burning mostly carbs. When you run out, you can get dizzy spells.
As I mentioned in my original post, I already had a series of blood tests and an EKG. The appointment with my doctor showed nothing this past week.
Your doctor likely did an A1C blood test which shows the average glucose in your blood over about three months. They might have done a non-fasting glucose test. Usually, these are supposed to be fasting, but it it's low enough without fasting, it's going to be low enough with fasting. I don't think either one would detect hypoglycemia unless done at the time it occurred.
A side note on EKG's. They can detect the presence of certain problems, but they cannot detect the absence of problems. I don't think you are having symptoms of a heart problem from your description and based on what your doctor said.
This is where I'd focus.
I only take Zoloft for depression and anxiety. And Advil for pain or fever. I'm not a fan of meds the way it is. LOL
Two of the side effects of Advil (Ibuprofen) and Zoloft are dizziness and hypoglycemia. The same for Zoloft. You probably think the doctor should know all the side-effects, but that's not the case. That's the pharmacist's job. The pharmacist just gives that sheet of paper with tiny print nobody can read. They all say the incidence is small, but keep in mind, side effect percentages are additive. You WILL get side effects from virtually every drug you take. You may not notice most of them. Even if you mention them to the doctor, they won't make the connection.
Zoloft increases serotonin levels through some magic mechanisms I don't understand. Anytime a person artificially changes a hormone level, there are unintended consequences. My information comes from The Pleasure Trap. Ignore the end of the book that mentions fasting. That's for people almost dead who have certain conditions.
To get to the point, you can manage your pituitary gland's release of serotonin through natural means.
Seratonin is released when we experience happiness as defined by making progress towards a long-term goal. You mentioned in another topic you have five people in the house. Of course, a source of anxiety is the impossibility of getting things done. I have a list of things to be done in the house, and I cycle through that list. Some things are every day. Others are longer term. It's physically impossible to do everything. At the beginning of each day, I decide on those items that I'll do each day. Each time you complete an item, you should get a little serotonin. When you complete all of them, you may get a bit of dopamine. It's more likely you will get a shot of dopamine when something really special happens.
For more information, I suggest reading the book. Doug Lisle likes to tell long stories so the reader remembers the information. Get to the point people won't like this.
Hope this helps or stimulates another idea that does help.

@CRISSY92 Most if not all of your symptoms can be related to Post Exercise Hypotension or PEH. PEH has been documented after exercises such as running, walking, cycling, and swimming. The longer and more intense exercise produces a longer duration of PEH. After I have exercised for 45 minutes on my elliptical or rower which is intense my Blood Pressure drops to 95/50, but I have never experienced any of your symptoms. You may want to invest in a device that you wear on your wrist that measures Blood pressure and take your BP when you experience these symptoms, just to ease your mind.

@GershonSurge Didn't mean to put simple carbs in there. I think I was having a bit of brain fog at the time I was typing. LOL. I'm also not taking Advil on a daily basis (hardly ever) and I've been on Zoloft for a couple years and Paxil prior to that for about 10 years. I'm confident it's not my meds, as I've been doing this same EXACT type of exercise since March of this year, which is like 5 months, and this JUST started occurring a couple weeks ago.
I really don't think it's my heart, either. I'm thinking of investing in a blood glucose meter to monitor my sugar pre-, during, and post-workout just to see what my numbers are. Might be very useful to me AND my doctor, since she has no other logical explanation. I do agree with your statement about the glucose test. Unless it's tested at the time of my symptoms, it's not going to show anything.

@Corney I watch my heart rate on my Fitbit, though, and my heart rate gradually comes down to a normal resting rate for me. If my BP were to drop quickly like that, I would think my heart rate would plummet, as well, right? Also, it's not actually AFTER working out, it's kind of towards the end, and I usually stay within the 30-45 min range for all exercises. I'm not sure that's what it is, either. But that's good advice!
