Worried about my blood glucose level

Is Metformin your only diabetes medicine? If it is then you must understand that it does not have a big impact in lowering your blood glucose. I would put your high bg response down to experience and refrain from having that meal again (or at least refrain until or if your response to carbs improves).
Your bg should continue to fall over the next few hours. All this is dependant on whether, like I said, Metformin is your only drug for Diabetes.

A day or so after I was diagnosed with type 2 I had a bowl of what I thought of as healthy cereal Special K. Result BG 17.9 and it stayed above 10 for hours and hours. I freaked out, talk about panic. Ah the early joys of testing and pre low carb days.

If it continues to be high, am I type1? I m trying to understand diabetes, but the more I dig , the more I get worried.

Stress less, you're not Type 1 and it was the food you consumed

No! 10 + might be high for you and is higher than you'd want it to be but if you were type I I suggest that 30 + is possible.

If you should be taking Metformin then take it, it's not something you can take just when your BG might be a bit high, it doesn't work like that. You've answered your own question really, carbs in meal, no metformin, no exercise. Three things and therefore not really a surprise when your BG is higher than you want.

Hello @biren1973 - Type 1 is generally diagnosed after a period of suffering ketoacidosis and with bg levels in excess of 28mmol/l - from a type 1 perspective your levels aren’t that high so no need to worry about being type 1.

As others have said you have answered your own question in regards to what you ate and the effect of this on your bg levels.

No. High blood sugar in a type 2 diabetic is just that: high blood sugar in a type 2 diabetic. Diabetes of any type can cause high blood sugar.

High blood sugar doesn't make you type 1, it makes you poorly controlled type 2. The blood sugar levels you have mentioned aren't in actual fact that high, for a random blood sugar to be diagnostic of diabetes it would have to be over 11.1. Certainly diagnosis of type 1 usually takes place when blood sugar levels ar over 20 or 30.

The difference between type 1 and type 2 isn't how high the blood sugar level is. The difference is the cause of the diabetes. Type 1 diabetes is an autoimmune disorder. Type 2 diabetes is caused by well everything else like lifestyle (stress, shift work, diet & exercise), hormones (PCOS), other medication (long term steroids for asthma etc). If your diagnosed type 2 you remain type 2 no matter how high your blood sugar goes or how you are treated. Unless this was a misdiagnosis and antibody testing shows you have always had autoimmune type 1.

Metformin is a cumulative drug. It works by the build up of the drug in your system. Missing one day might not make any difference to blood sugars that day. The difference might come in the next 4-5 days as it drains out of your system.

Hi

I usually have 6 or 7 , 2 hours after my dinner. But tonight I went to a restaurant with my family and couldn't control myself and as a result, I had an South Indian dosa (made of rice and semolina) . I checked on the net before eating which says 17g per one dosa.

But to my surprise when I checked 2 hours after food, it came out 9.6. Then thought it might have dropped down to normal level 3hours after food, but to my surprise I tested three times and each time it came different.
1st time: 10.6
2nd time:11.2
3rd time: 10.2

It's very high for me for type2, never gone up to that level.

My medicine metaformin is also finished and I m not taking as need prescription to get from pharmacy. Also I usually walk 4 to 5 kms, but today I didn't walk much.

I will check tomorrow morning to see if it is high or not.

I m worried and wondering if the food contributed much than exercise. I m not counting medicine as yesterday I didn't have medicine but bg was 6.2.

If it continues to be high, am I type1? I m trying to understand diabetes, but the more I dig , the more I get worried.

Regards

Yes your food caused these high bgs. For sure.
What most of us type 2s who post here we try and avoid such carby foods but as a one off it seems to come part and parcel of type 2 diabetes.
You will have experienced this before but was nieve to it as you didn't test.
Keep those one offs for special occasions? Many eat such meals weekly or a few times a week which can contribute to type 2 diabetes.
You will have your eyes opened but your rationale will put you in a good management place. Test test test to see.

Like others have explained a type 2 cannot turn into a type 1 but type 1s can also develop type 2 ontop of type 1.
Have a look at the low carb programme on this forum. It's very good.

I did a big mistake by eating that, I m repenting why I did this foolishness.

So do you mean rice takes more time and as a result the bg goes up. So does it mean if I measure 5 hours after food it could even go more than 10?

Yes carbs can give delayed bgs, especially when those carbs are mixed with high levels of fat. Fat slows down your digestion.
Fatty protein before bed digests slowly and can reduce fbgs in some diabetics. Counteracting a liver dump or technical term called a dawn phenomenon.

Ya true. But yesterday I didn't take medicine, but my BG was 6 after food. So I ruled out medicine. But what surprises me is my 3hrs after food bg level is even higher than my 2 hours after food level, don't understand why? Any idea?

What was inside the dosa? potato?

biren1973 said:

No potatoes. Only plain dosa, but very big in size.

OK can't have been that then..

You may get a delayed high fbg tomorrow where your liver dumps all that extra glucose made from the carbs. Or you may be lucky and your body may have processed it fully by now.
Let's see.
A fatty protein before bed can act as a liver block to higher fbgs.
Really the best defense is avoiding those nuisance carbs instead.

I checked this morning and it was 5.8. Do you mean I may get high bg again today at some point because of yesterday's food?

At anytime your body thinks your fasting. Most commonly through the night. Its called a liver dump.
Everybody's processing time varies so you may have done this already yesterday when ate less to compensate for big meal or it waits til your low on food being processed now.

It becomes a vicious circle if a none sufficient insulin taking diabetic constantly eats a high carb diet.
With you being a none insulin taking diabetic its advised to keep those high carb meals as a very rare occasion, if at all.

Please check in and let me know if you experience a higher fasting bg in the morning. Please.
