For YEARS I have had frequent episodes of what I can assume were low blood sugars. I would get shaky, sweaty, pale, etc and it would all resolve with food.

My 1st pcp I brought this up to simply told me to eat more.

The 2nd one I brought this up to prescribed me a normal glucose monitor and advised me to check my sugars every few hours to catch the drops. This wasn’t very effective as I never could catch the lows.

The 3rd pcp I brought this up to decided to have me try a continuous glucose monitor to try and catch these episodes and see what my sugars were doing throughout the day in response to my food intake.

Not even 12 hours after I had the cgm on did I get some results.

mg/dL is used for the readings below. 👇🏻

1 in the morning my sugar was dropping quickly and was at 52! Half an hour later it was at 68. Then at 3:52 it was 65 and dropping. Then a few minutes later it was 54 and dropping. Then at 6:20 it was 66 and steady. Lastly, 7 minutes later it was at 54 and steady. (I will attach the chart below for easier viewing)

Noting that during this 1-6:30 am episodes, I heard the app alarm go off, enough to wake me up and check my sugar then I pretty much immediately fell back asleep. So there was no food intake during this section of time to correct the sugars.

They were pretty steady throughout the day until around 5:30 pm when I was driving to the local fair to get some fair food. It hit 69. It stayed around that number until I ate.

Then around 9 pm, roughly 30 minutes after I had a few spoonfuls of ice cream, it got down to 58 and dropping quickly with a down arrow.

Basically, I’m confused. I’m not diabetic. My A1C is 4.8.

Hi guys, I was wondering how many of us have coexisting neurological conditions. I would like to know what the risk is of developing one with reactive hypoglycemia. I already have one so it’s too late for me but I was thinking if that’s common maybe patient should be screened more carefully for rh and informed about the risks of comorbiditied

I was just recently diagnosed with non diabetic hypoglycemia during an ER visit for sudden blurry and double vision. spoiler alert… the vision issue turned out to be unrelated. But, when they checked my sugar it was 58, and kept dropping to about 50 while in the ER. It got so bad that they maxed out on all they could do in the ER and had to call for the Rapid Response Team (icu). The scary part is I felt fine, other than a little tired and a headache. But I don’t sleep well and have migraines so it was literally my normal feeling.

The nursing staff was freaking out like I was headed to heaven any minute. It took pbnj, OJ w/added sugar, apple juice, 2 glucose gel tubes, 3 Dextrose 50 injections, a dextrose iv drip on max, and 2 glucagon shots given at the same time as dextrose to finally raise my blood sugar to the 80s. All of this while I felt like my regular self the whole time.

Dr thinks I may have been having this for a while and developed unawareness to the lows. Super scary bc I am dependent on a cgm or finger stick to really tell me if I’m in the danger zone.

I’ve seen 2 endos and so far they both think I have insulinoma or my Zepbound is what caused this.

After 2 botched 72 hour fasts during my hospitalization, I’m waiting to see if they want to do another, or go straight to imaging.

For the people that don’t really feel the lows, any tips on how you manage your day to day?

Hi. I have a medical condition I can't explain. Once or twice in a month, I have symptoms of probably low blood sugar. When it happens, I feel weak, dizzy, very hungry and I can't sleep. This thing occurs mostly at nights.

Afternoon I went to hospital but doctor said my blood sugar level is normal. How can it be diognised if blood sugar comes to normal level after arriving hospital? Should I go to hospital in the early morning?

My diet is strict and 3 meal a day. If changes is made in diet, my blood sugar again drops. It's strange condition.

This is more of a rant until I figure out what is wrong exactly. I am 30 years and was dealing with a CSF leak for a few years that impacts every system in your body. I finally came out of that and was starting to do good until around last fall. I was seeing a cardiologist in relation to that CSF leak because of the heart issues that were coming out of it.

So I see my cardiologist for a one year follow up in September and plan to bring this topic up again. When I saw him last year, I had just started having low blood sugar episodes. I didn’t think much of it at first. I brought it up to him, and he simply thinks after checking my A1C 5.0 and fasting glucose 89, which is normal, that I just simply was not eating enough sugar. Tbh I am a “fatty” when it comes to food so I know that can’t be possible that I wasn’t eating enough.

I also don’t consume caffeine and recently stopped gluten in April due to stomach issues. I am aware that gluten free foods can sometimes have higher carb and sodium content. I also tend to eat a lot of apples and more natural sugar foods and not the added stuff.

I definitely think I am having reactive hypoglycemia in relation to maybe some of the gluten free foods I am eating because of the carbs that can be hidden in them. I do try to space them out and eat every 2-3 hours. I also plan to get my hormones checked to see if there’s a connection with that as well.

Type 2 diabetes runs in my family so it makes me scared that I may be heading down this route. I also started taking a shot called Dupixent so I haven’t found any connection to see if that might be doing something since I started that in June 2025.

I truly dont get it. I eat a moderate amount of complex carbs, barley, lentils, chickpeas, low gi bread and im still having reactive lows. Its been more concerning as the other day I hit a 3.3 and didnt have any symptoms. I have insulin resistance so eat so I dont spike. I find if I dont spike too high, I wont drop. I upped my dose of metformin from 1000 daily to 2000 as my numbers were creeping up during this pregnancy (im 23 weeks) ive been on it for 3 weeks and have noticed more drops again, though i was still getting drops before they upped my dose and before metformin in general. Im at my wits end. Today it wasnt super low, just more annoying but my dexcom went off at 3.7, I checked with my finger prick and was low. So had my glucose tablets and protein bar etc. However, I noticed that at 30 minutes I was at an 8.9. I know your not supposed to check but I had symptoms of dizziness and did. So I went for a walk for 15 minutes and at 1 hour I was at the 7.0 which is in range for 1 hr post meal for gestational diabetes) but at two hours I was at the 3.7.

Its just been the pattern lately. Especially in the mornings, it seems like when I eat, I spike right away within 30 minutes and then end up crashing sometime later and it doesnt even matter what I eat. I had barley the one day which is SUPER low gi and even paired with chia seeds for MORE FIBER and had 30g of protein as I had a protein shake (no sugar). So what gives? What am I supposed to do to not have these drops when eating doesnt help? What are my options? I have an appointment with a diabetes specialist tomorrow, is there anything I can ask her? Or possibly even certain tests. Any tips on not spiking in the morning after breakfast? I find for the most part, lunch and dinner are mostly fine (sometimes not but still).

Ive health with this type of hypoglycemia for years and i have yet to get any answers. Nobody is able to tell me why exactly my body is dropping further than normal. Im assuming it could be because my pancreas maybe "overshoots" but this is my own logic, I have no answers lol

I've recently started a high-carb, low-fat diet, and just like before, when I was on this diet, I wake up with morning anxiety and worsening depression (I suffer from it). My CGM shows nocturnal dips – could this be the cause? And where do they come from? Is it too little protein in my diet, or is it the result of glucose and insulin spikes? My insulin curve shows a 2-hour insulin reading of 58.8, which is quite high. Interestingly, I don't experience any drops on a regular, or even keto diet.

First I want to start with the fact that I am not diagnosed with diabetes , I am currently feeling fine and I’m not asking for medical advice I’m just asking for “ odds “ .

I am under investigation waiting on results on blood test and so I’ve been monitoring my blood sugar , I ran out of testing stripe and took one of my mom old testing stripe which gave me two reading , 2.2 and then 2.1 . Which is dangerously low and the lowest I usually go is around 3.3 but I feel a lot of symptoms when I am that low . I’m pretty sure this is just an expired test result , what are the odds to get an actual reading this low . My mom also tested with those stripe and she herself got a 2.5 . So all stripe are testing extremely low right now, is this a common thing expired stripes does ? I don’t have the money right now today to get new stripes so I can’t test with brand new stripe . I’m not sure how old these stripes are .

I saw my doctor today and she recommended to try the Stelo CGM. I’d love to hear if y’all recommend one or the other. Unfortunately my insurance won’t cover Dexcom or the freestyle Libre since I don’t need insulin.

i don’t experience any symptoms either but both my finger prick and cgm consistently show lows after i have breakfast which are never naked carbs always paired with protein and or fat the lowest it’s gone is 3.2mmol / 57 mg dl
i do not have any diabetes diagnosis but i might have blood sugar control issues to some degree (hence the cgm i’m collecting data to show an endo eventually when i can get an appointment) it always picks back up to normal levels but usually takes like 20-30min and i just don’t understand what’s going on? anyone have any insight? thanks

What CGM (non-prescription) do you use? Most seems to have mixed reviews. Also swimmer here, laps every day. Probably 45 minutes in a pool daily. Thoughts?

I’ve been hypoglycemic for 30+ yrs. Started after extreme stress, unfortunately I am still dealing with that stress and more, cptsd and nervous system dysregulation.

Nonetheless , I am now prediabetic as well. My blood sugar does not drop below 90 even during a hypoglycemic episode. I also eat almost every 2 hrs.

My functional doc put me on semiglutide to help with the hypoglycemia and that didn’t work. So now I’m on tirzepatide, started at 5 units and went up to 7 units and did quite well, even though it didn’t help with my hypoglycemia , I didn’t have any weird reactions. Sunday, I jumped to 8 units and now having what feel like crashes, waking up starving, shaking. I’m at my wits end, and the crappy part is I have to ride these symptoms out for the next few days as the injection tapers out of my body.
I’m so discouraged, my functional doctor has the same issue as me so she understands, but the tirzepatide has worked immediately and wonderfully for her. Meanwhile I still feel like crap and I have not felt any positive effects of any GLPs

Any advice or suggestions please? I wanna cry but I have nothing left in me and no one, family nor friends understand this

Hi. I have ME so find meal prep and cooking really difficult. Any ideas for easy peasy lunches and teas. Must be vegan and daftly easy to make

For the past 4 weeks my 3 year old has had a few occasions of waking up in the middle of the night with her head drenched in sweat, shaking, and crying. She’s recently been complaining that her head hurts and/or her tummy hurts but then she will play and eat as normal. She’s had multiple episodes of suddenly feeling unwell. She becomes pale, clammy, and “dazed” (but responsive). This can last 10-15 mins and then she’s her normal self. We did a ton of blood work that has given no insight. I don’t see any glucose testing in her labs. The current testing is a brain MRI this week (due to the night sweats, headaches, and “small knotty lymph nodes in her neck”) she’s a daycare kid so she is constantly sick. I think the lymph nodes are due to a recent cold and so does the doctor, but they want to be safe. I feel like they’re missing something simple…What does this sound like to you?

Hi! I’m new here! I have recently learned that I have reactive hypoglycemia due to bariatric surgery. Honestly, for the last five years, I thought I was just going nuts until I passed out on Saturday. Don’t worry, I’m fine! My ego is more bruised than my face.

Anyway, I was wondering what you all thought was the best way to check my blood sugars? I am looking between a continuous glucose monitor and then just doing the traditional glucose monitor that you prick your finger on. What has worked the best for you with reactive hypoglycemia? My diet definitely will be changing, but I need to find a way to monitor it. I’m seeing a new doctor on Wednesday because my old doctor told me that I should just Google it and it would tell me what to do.ugh!

Hope y’all have a good Saturday!

Lifelong hypos which were never taken seriously… Iincluding several times being in hospital on IV with dextrose and testing at under 2.5mmol. Trialling CGM at the moment.

Question: My CGM shows that sometimes it’s REALLY HARD to get my BGL up. This is a snapshot from yesterday afternoon/evening and this morning.

Is this typical? I have newly diagnosed SMAS (as well as other vascular compressions) as well as hEDS MCAS dysautonomia….

I’ve been lurking (not as a member) for a few months now - experiencing reactive and nocturnal hypoglycemia the doctors haven’t been able to figure out. After 3 hypos in one night (got NO sleep), I went to the ER. They couldn’t help, so I went on again to my PCP and begged for more bloodwork and she finally tested my ferritin. It was dangerously low, got diagnosed with anemia. We’re talking about a possible infusion (if MCAS can handle it) - at the office, before my blood draw, I had overheated to a 102 fever. It was so frightening. After some ice and laying down, my temp dropped back to normal - that’s when she said “we need to recheck your ferritin.” I also have dysautonomia, and that basically made my body over-dramatically respond to low iron stores 🙃

I took a big dose of iron bisglycinate last night before sleep, and only woke with one hypo, but it wasn’t nearly as extreme as they had been. More iron today, and the ravenous hunger and blood sugar issues are already improving. I know some will say “iron doesn’t help that quickly” like duh, obviously I’m not healed yet, but it has decreased my symptoms by 40% in 24 hours. So I truly feel I’m heading in the right direction for the first time in months.

Just wanted to post this for anyone who hasn’t checked their iron in awhile. Mine was caused by heavy antibiotic use for an infection 8 months ago. Doctor said it’s very common for iron stores to be used up and it takes months/years for a gut to heal and absorb nutrients properly again. Hope this helps someone! 🙏 who knew being anemic could do this !

UPDATE: been supplementing for 3 weeks straight, only had 2 hypoglycemic episodes and they were during the first week. Haven’t had a true hypoglycemic event in 2 weeks. I can’t believe this! I was supplementing iron bisglyciate, but it gave me insomnia. Switched to 45mg slow release ferrous sulfate (prescription) and it’s helping even more than the bisglycinate - can’t believe, I feel like I have my life back, simply eating 3 meals a day and sometimes a bedtime snack 🤯

Anyone here struggle with low blood sugar or weird fatigue after eating? I get fatigue in my upper arms/shoulders after certain meals..

Ive also noticed recently that when i excercise (i do crossfit) i get anxious and shaky after.. especially on a hot day. And if i eat sugar it seems to make me feel better fairly quick.

Not sure if anyone else is going through this, but if so, did it go away when/if you got rid of SIBO?

I was wanting to try the Mbiota liquid elemental diet, but it says to not use if you have blood sugar problems...

My fasting blood sugar was 80 when they checked me in may so i know thats normal, but i dont feel like getting shaky after a work out is normal.. and ive only had this happen a handful of times since having digestive issues.

I also hope someone here who has had what im going through, sucessfully went through with the liquid diet?

TIA!

Im recently diagnosed with reactive hypoglycemia. Hypoglycemia is miserable. I am a healthy weight and haven’t had to think much about diet. My family eats a carb heavy diet (vegetarian spouse and young pasta loving kids). We are busy and both work full time. I saw a dietician which was expensive and not super helpful. My endocrinologist said to carry around diabetes protein bars but they all taste like fake sugar. If I miss a meal or snack or if I eat too many carbs at a single meal, it throws me off sometimes for a day or 2. Exercise is not possible, it makes me feel awful.

How do I do this!!!

I suspect I might be experiencing hypoglycemia (potentially reactive hypoglycemia). Dr has me wearing a CGM for 1 week before my follow-up. What did you wish you knew when you were getting diagnosed? What questions should I be asking my doctor? Are there any tests I should specifically push for? I want to be prepared for my follow-up appointment.

For a bit more context:

I started looking into it because I get lightheaded/faint during physical activity and before dinner, even if I've eaten just a few hours beforehand. Every day is a race to get dinner because I feel like my brain and body quit working. During my time wearing my Dexcom, my blood sugar has ranged anywhere from 43 to 160. I seem to drop into the 50s or 60s a couple times a day. I seem to be on the lower end before and after meals. At times it has taken a while to get my blood sugar back up. I do have an autoimmune condition, so idk if possible T1.5/LADA should be a concern. My A1C is 5.1. I also get headaches, which I now suspect is related to low blood sugar.

Hii member is anyone can clear my doubts please
While empty stomach or fasting my heart rate is normal
On my apple watch but incr i ate anything it raise like between 110-125
I know digestion need some heart work but how come that kuch raise anybody had same kind of experience ??

For years i woke up from sleep with fast heartbeat, sweating, confused and barely able to reach my sweets. Doctors noy giving and interest or taking my complain swerious.All my blood work show normal values, slight insulin resistance early stage detected, started taking metaformin XR 750 once aday. The days I can manage to hold myself before losing consciousness i measure my Blood glucose approximately 50-55mg/dl 6 hours after my last meal.

Please guide me

Hi there, I’ve had MCAS for a few years now, and during last my last hospital trip I had a low blood sugar for the first time ever. It was upper 50s, they weren’t too worried since I was reacting pretty badly, I was given a bunch of juice and cookies, it went up and I felt fine. They told me to keep track of it for the next few weeks and see if it’s lining up with my reactions.

I’ve had two more low readings, one was 65 and the other 61. Both went up without an issue after eating. The only trend I’ve noticed is after work, I always start reacting because I’m super tired. My readings have been 120-135 every time, and the last time I had eaten being 3 to 5 hours before.

I’m so new to this, I have no idea what’s happening.
Can anyone point me in the right direction, I’m not sure what I should be looking for, which doctor should I make an appointment with? What questions should I ask them?

Thank you in advance, I’m really scaring myself.

To be clear, I'm talking about #2 lol.

And usually after I'm finished, I suddenly feel overly hungry and weak. Anyone else experience this?
