Hi again,

Bananas are relatively high in carbohydrates, as are any type of breads.

calculate carbs, not sugar. if you know how much each carb raises your blood sugar, such as 1 carb generates a 3 point rise in glucose, ands you ate 25 grams of carbs, that would elevate ones glucose by 75 pts over the next 2 hours. this does not factor in any bolus insulin you may have taken or your activity level at the time or during next 2 hours.
If I translate your 5.8, 8.4 and 9.7 values from mmol/L to mg/dl , I see a blood sugar when you awoke of 104, then in 2 hours it was 175

Yes .... thats the right numbers..... what confuses me is that i am supposed to spike at 1 hour? ..... and the 2 hour reading should be lower?..... or did i get that wrong? ...... i am not on insulin just metformin 500mg x 2 daily

this may differ from one person to another but the spike can have a duration of 2 or even 3 hours. There are many signaling processes(moving parts) going on between your hormones, pancreas, brain and liver that make for a network of conversations & conversions.

Unfortunately there isn't really a set time to "spike" after a meal. Your blood sugar rises as you digest food, so how quickly that happens really depends on the content of the meal, your personal digestion, etc. For example, a meal of mostly carbohydrates will digest, and cause a spike sooner than a meal that is mostly protein and fat.

A lot of the diabetes guides assume that you are eating a mostly carbohydrate meal, and so they talk about spiking at 1 hour and leveling out at 2 hours. If you are eating low-carb though, most of your meal is protein and fat, and you may see a gradual longer rise 3-5 hours after the meal because the fat increases digestion time. Some foods like pizza and pasta seem like they would spike sooner, but often end up spiking much later and longer than you expected.

There are other things that can impact when you see spikes, such as gastoparesis (delayed gastric emptying), medications, bacterial infections of the gut, etc.

What this means for you, is that you may want to change when you test your blood glucose after meals, depending on what you ate. The numbers you saw, where it was even higher at 2 hours than 1 hour, isn't uncommon, and when that happens just keep testing each hour until you see it level out.

Then you can use that information to understand how various meals affect your blood sugar and make changes accordingly. Don't beat yourself up about it, just use it as more information to figure out how to manage your blood sugar.

Another factor, especially in the morning, would be your liver's contribution. It could be that your liver dumped some glucose after you woke up and before you ate and your BG was higher than you thought before you even ate that rather high carb breakfast.

I found early on that my BG spiked closer to 2 hours than one. And I do have a mild case of gastroparesis (slow stomach emptying), plus I eat very high fat which contributes to a slower digestion. However, since I reduced carbs even more, and especially at breakfast (close to zero carbs), my BG has leveled out and doesn't spike much at all.

As Daytona said, it's very much an individual thing.
