Low Blood sugar and extreme Fatigue?

So, this morning I had 2 hypoglycemic readings (I'm pretty sure the cause was from me starting a new slightly more intense exercise routine yesterday). I was exhausted during and after both of them, so much so I just went back to sleep.

Caffeinated drinks don't seem to help boost my energy after correcting a low, and I was wondering if you guys had any tips on how to return to normalcy quickly! School is starting again next week so can't really just go back to sleep all the time :)

If it helps - I'm currently using the omnipod insulin pump and also have hypothyroidism.


For me it could be several hours, sometimes a day or so. It depends on how low and if I overcompensated and went high or not.

Have you considered adjusting your basal rate prior (up to 2 hours) to your exercise? How about a snack before and/or during?

It might take a few days to get a handle on the routine change. I know it does for me.

I suffer from AIH, Amiodarone-Induced Hypothyroidism (currently in the monitoring stage, without treatment), so I'm easily (continually) fatigued. Plus I'm on a handful of other medications so much of the time I'm trying to decipher which condition/side-effect is responsible for the varying symptoms.

And to think my wife was concerned how I would occupy my time (and my brain) when the grand kids started school this year. :-)

I'm a 'stay at home' grandfather to a 3, 4 and 5 year old - talk about exhausting!

Lows, highs, and especially rapidly changing blood glucose levels can really tire one out. How low were your readings this morning?

Whenever I make changes, like adopting a new exercise program, I like to watch my blood sugar readings more closely. I use a CGM and test frequently already, so what I do is to upload my devices and look at various reports to try and untangle things.

I see in your profile that you use a pump, diet and exercise to control your blood sugar levels. I would recommend that you start to keep a journal for a short period, maybe a week. You can then learn some things that will help you to adjust insulin, exercise, and food to prevent large and frequent blood sugar swings.

I'm retired now but during my work life I remember taking sick days to allow me to recover from low blood sugar events that rebound to multi-hour high levels. It is tiring.

If it were me, I would track basal rates, boluses, your food descriptions including serving size, exercise intensity and duration, and anything else that you feel impacts your blood sugar levels. I know this is a lot of work but you will learn some valuable lessons.

Have you read any blood sugar management books like Think Like a Pancreas by Scheiener or Pumping Insulin by Walsh? They provide a good deal of tactics to help straighten out the situation you are in. Invest in your knowledge about diabetes. It's one of the best things you can do for yourself long-term.

I don't know much about the thyroid but I also have hypothyroidism. I don't think it has affected my blood sugar situation that much but I'm aware of others here that struggle with getting their thyroid under control.

Good luck to you!

A string of hypos is particularly tiring even if they aren't super-hypos. It also messes up my hypo sensitivity for detecting future ones!

Right now I'm suffering from fall allergies, and for me some of the allergy symptoms (particularly "confused" and "impatient") happen to coincide with hypo symptoms. So I go around testing my bg all the time because the hypo warning dog in my head is barking all the time but usually my bg is OK.

If you are hypothyroid are you being treated? Do you regularly monitor your levels to make sure you are stable?
