I know that with our condition exercising has been known to cause a drop in blood sugar. If I work hard around the house and do not eat enough carbs, my blood sugar will drop really low. This just shows that your body is still out of whack. How many carbs did you consume that caused your blood sugar to go up to 181? I would just continue to keep a close eye on your blood sugar, and if you are still having issues, please contact your Doctor. This disease is very finicky at times. I hope you are feeling better today.

it is hard, but do let the doctor know about this, how many carbs are you eating per meal? regular crackers can raise the numbers along with the peanut butter, so do call the doctor, have them refer you to a dietician regarding how to handle

as Jeremy said, this disease can be fickle and can progress

Yes, i have had such experiences when i exercise and then feel so weak as if i am going to pass out.
To overcome that i test my sugar before i go for walk. It helps me better control. Also i have been told that i worry too much about fainting and that is also called fear of hypoglycemia. It happens when we have an episode.

But the key is to keep going, you cannot really faint unless your sugar falls below 50.

Consult your doctor or dietician and dont give up exercise. Keep it up. You are not alone. :)

Carry a light snack or glucose tab with you at all times. I know it's hard but you need only a little bit crackers and peanut butter probably you over did it trying to rush the sugar back up. That made it go high and that kept you feeling terrible. Describe what your "terrible" feels like. You need only 15 grams of carbs to raise your blood sugar, but you need to give it at least 15 minutes after your last bite to see the raise in blood sugar. If it's still too low then have 15 grams more. I know it's hard because when I've had lows it really sucks feeling like you're going to pass out, but you really need to just have some water, flavored water or tea when you're waiting it out.

Hope that helps a little and if you're having lows talk to your doctor. If you're on metformin again you may need to try a lower dose or be off it completely if you're back to eating good and exercising.

Been a Type 2 diabetic for 2 years now. Personally speaking, I've been through my ups and downs. Most of the time, my blood sugar readings are about normal or toward the high side. However, after exercise I've dropped down to 63. The point is if you're gonna exercise, try to do it when you're above 100.

I've had some really bad experiences before I was diagnosed and went through some of my worst feelings ever at that time. If you haven't already done it, go get an A1c done.

Whenever you get low, like what some people here are suggesting is to keep some candy or glucose tablets with you at ALL times. Just as a preventive measure against fainting, try to be on a lookout for these drops in levels.

I'm hoping the best for you and encourage you to drop by often.
