Sharp drop in blood sugar

I used to workout quite a lot. 60 minutes on AMT tread climber. Weight lifting 45 minutes 3 times a week. Developed bad case pneumonia and really knocked me on my butt. That was couple years ago. I'm back on my AMT at 20 minutes with 15 minutes of weight lifting.
All of that to ask if anyone has noticed a large drop in blood sugar post exercise. I have noticed a 65 to 100 point drop I BG levels at 15 to 30 minutes after I'm finished. Has anyone else noticed exercise does that for them?
I really appreciate your responses. I'm trying to understand this condition and how it effects me. This is life or death for me. I will win because I hate to lose. Lol.

Exercise is a magical thing in that it is the only thing that our body does where glucose doesn't need insulin to get into the cells where it belongs. That is why you can drop after exercising. That is why it is encouraged so much because it helps your body so much. Now if you exercise a lot and don't have enough glucose to go around, that is when you drop too low. So you may want to check before you start.

If you are near 100 before exercise you should consider eating something that will give you a slow release of sugar. If you are above 300, the opposite happens for some reason and you should not exercise, but get your numbers lower before exercising.

I am on the CGM have had it since October, and I gotta say I love it! Like everything else it's not always accurate especially if you're rising or dropping too quickly, but when you are on track it is almost always right on! When I exercise I make sure I am over 120 BG before I start and if it's hiking I will carry a juice to sip because I drop too quick. The CGM alerts me when I drop below 60 and when I am over 140. I am a control freak so these are the numbers I've set it on! THe CGM was prescribed because of my continuous lows, and it has to be approved by your insurance. If you're experiencing a lot of lows you may want to talk to your Dr. About the CGM. The downfalls of it are that it has to be within 20 feet of you at all times, you insert a new sensor once a week, and although it is waterproof sometimes it will lose it's readings after a shower, so I cover mine up with a waterproof bandage. Hope some of this helps!

I have been researching CGM. It seems they are more interested in trends, or at least according to NIH. That seems contradictory to its' name. Is it for monitoring BG? Does it replace finger sticks?

From the NIH site I posted to answer Snuggles:

"Continuous glucose monitoring (CGM) systems use a tiny sensor inserted under the skin to check glucose levels in tissue fluid. The sensor stays in place for several days to a week and then must be replaced. A transmitter sends information about glucose levels via radio waves from the sensor to a pagerlike wireless monitor. The user must check blood samples with a glucose meter to program the devices. Because currently approved CGM devices are not as accurate and reliable as standard blood glucose meters, users should confirm glucose levels with a meter before making a change in treatment."

I have seen people who have CGMs who reported that they test (by finger sticks) their BG 5-8 times a day, but if memory serves they were in calibration mode for the CGM.

Note that it monitors glucose in the "tissue fluid" (lymphatic system?) and not blood. and since it is on 24/7 it is continuous. It can alert the wearer if they are going into a hypo or if they are going high.

I myself have no hands on experience with them but only am saying what I have read.

Yes, I use to to Turbo Fire and Les Mills workout, until I got sick. When I exercise that extreme I have a tremendous drop too within 15 minutes into my workout. My doctor suggested me to take my pump off and get my blood sugar elevated. My nutritionist even suggested to drink regular Gatorade, also suggested the protein/carb.

Howdy "95n"

Yes excercise does lower one's BG. In fact it is a great way to lower one's BG levels without medication. Physiologically exercise removes or reduces insulin resitance temporarily so the glucose ia able to get in and feed the muscles. Different people have different reactions as to how much 30 min (for example) exercise will lower their BG levels but unless the exercise causes stress, it works for most people

Praying for your improving health

Thank you. That's consistent with what I noticed. Does the carb/protein help with the drop 3-6 hours later? Seems like a long time for an effect. Forgive my questions. Lol. I'm a student by nature and probably 'why' is one of favorite questions. Thank you again.

I'm mainly a runner now. Usually if I run more that 4 miles I can have a large drop from 130 to 58 about 3 to 6 hours later. So I try to have some carb / protein after. And that helps. Otherwise I have to make sure and keep an eye out.

I do wear a CGM now. And this helps to warm me on a large drop.
