Hi everyone, I am new here and glad to find this community.

I am newly diagnosed as Type 2, not on any medication yet. I want to try to control blood glucose level via diet and exercise first.

A very strange thing happened last night. My BG level was
100 @6:20pm right before dinner
Then took a walk for 1 hour
105 @8:30pm two hours after dinner
175 @midnight

I only drank water after dinner. It really puzzles me. Just wondering if similar events happened to some of you guys.

Thanks for sharing in advance.

The sauces in Chinese food are often very high in carb and raise my blood sugar a lot. You may be able to control it without meds, but you would have to follow a very low carb diet. Make sure you are seeing a good endocrinologist who can advise you. Keeping your A1c below 7 is very important…a blood glucose range between 80 and 180 should accomplish that…(that's what I do, anyway for the last 50 years). Good luck.

Hey Bryan,

I don't know why that happens but I have a cousin that's also diabetic. With her exercise sometimes spikes her blood sugar. I had the same problem at first but I've had it for nine years now and now it goes the other way. Before I was diagnosed I was a runner and a biker and didn't eat more than once a day if even that. After I was diagnosed I remained doing the same thing and my blood sugars were always high after exercise. I think what helped me the most was to eat a little snack before exercise. Not a sugary snack but veggies and a little protein. Eventually it just sorta leveled out. It takes some work but don't worry things will get better. I wish I still ate like that but old habits die hard. Luckily my blood sugars don't spike just because of exercise anymore. I will do a little research to see if I can help you a little more with solving the problem and get back to you. Stay strong. Things will work out.

Thank all for your comments and suggestions. I am still trying to figure out how to count carbs since our home cooking are Chinese food.i try to eat less starchy food, lean meat,etc. I'll do more tests and report back.

Trying to type on an iPhone, but it won't let me go back to make corrections. I'll follow up later from a computer.

What did you eat for dinner and what were you doing prior to midnight. That is if you want to t ell us. The reason I ask is if you were doing something that caused an adrenalin release. That could do it. I got in the habit of pumping too much adrenalin. My A 1c went from 7.5 to 8. I didn't change my diet. I learned to stop the adrenalin rush and my blood sugar went back to 7.5 which is good for me. Grandma Rose

if you do not need to be on medication, then that should not happen, if you ate low carb. it depends on what you ate. that is strange to me.

You don't indicate what or how many carbs you ate which is an important piece of information. Some carbs digest more slowly than others ( and may take longer to show up in your BG. Your walk/exercise may be why your BG did not significantly rise in the 2 hours after dinner. Some anaerobic exercising (weight training) and competitive activity can actually cause a rise in BG due to the adrenalin that is released. Another cause could be that after your walk, your BG actually continued to drop and your liver dumped glucagon into your system to get it back to more normal levels.

I'm not up on the exercise/BG information, but that would have been my guess also the liver dumping glucagon to level things off.
