Hi, as mentioned in my initial post I was diagnosed type 2 a little over a month ago. We found this out when I went for my annual blood work (fasting) as required by our insurance company. When I went to the Dr. I was completely exhausted, it was getting to the point that I was falling asleep any time I sat down for even a minute. The Dr. was going to run a thyroid test as well.

Much to my surprise when I got a call back 2 days later, I was asked to come in again in two weeks for more blood work because my sugar was higher than the Dr would like. It was 125. So when I went back again, it was 124. The Dr put me on 500mg Metformin twice daily, and told me to check my sugar levels 1-2 times per day. That was pretty much it..oh and come back in a couple of months for him to check my sugar again.

I have been trying to do some research and am not sure if I am understanding correctly. There is so much different information out there on the internet. Am I to understand that at fasting 124-125 is not that horrible?

Either which way, I am having a problem keeping my levels controled, or so I think. I am going by this information (which is what I found in the packet with my One Touch Meter the levels I am going by are as follows:

Bef Breakfast (fasting) - 70-105
Bef Lunch or Dinner - 70-110
1 hr after meals - Less than 160
2 hrs after meals - Less than 120
Betw 2-4 AM - Greater than 70

Well for starters I never take it between 2-4 am…second of all, I cannot see where only 1-2 times a day of testing is an effective way for me to try and control my I was doing it 3 times a day, but I think from now on, I am going to do it before and after each meal..

*should I also be doing in the morning and before bed??**

I am usually the highest in the morning (after fasting) the highest being 143 and the lowest being 103…The average is about 120-122. My highest before dinner has been 128 and my lowest has been 109…with my average being about 128-120ish…Then 2 hours after dinner my highest two have been 182 and 204, but the 182 was after a Burger King binge and the 204 was after a binge of 2 alcoholic beverages…I have been as low as 92 1 hr after meals…

I know a lot of it needs to be controlled with my diet…which I am changing. I have downloaded a lot of low carb recipes, and have been eating more fruits and veggies than I ever had. Also more chicken than any other kind of meat.

Now finally…after my loonnnggg explaination my questions at this time would be

1. Are the levels that I am comparing to pretty accurate?

2. Is it better to test 1 or 2 hrs after meals?

3. What should my levels be at bedtime?

Any other suggestions would be so greatly appreciated…

i don't know what your target range is but its important to also know this., you are spose to wait 2 hours after eating or drinking any thing to check your sugar after your fasting before breakfast be cause you will not get an accurate reading,. my doctor has us checking 1 time a day do to insurance but our target is 80 to 150 is OK he don't want ours to go above 150 or below 80 a normal range is 80 to 110 on fasting before breakfast , is pretty normal i hope this helps you may also want to try keep a food diary l of what you eat and of what foods you notice make your sugar go up .

If I could, I would send you $1000 in cash each week for morning readings of 125 or less! I think that the target is generally around 100 because if it is at 125 when you start, then you do not have much wiggle room. If you don't mind "over testing" yourself for a week, I think you and your doctor will see a pattern and see what, if any, changes need to be made. Try this testing schedule: am fasting, 2 hours later, before lunch, 2 hours later, before dinner, 2 hours later, before bed. This will be 7 test per day. Now, I use the area below my elbow and never use my fingers. Do this for a week and you will have a good idea where you are.
You will find that almost all fast food will send your sugars up fast and hold them high. For me, corn, peas, carrots, and potatoes all put it up high fast, as do fruit juices. It has gotten to the point where if high fructose corn syrup is the first or second ingredient, my wife won't buy it. Even in "whole grain" bread. gotta read the labels and limit your carb servings to about 3 per meal (1 carb serving equals 15 grams of carbs) .
Alcohol itself will cause your BS to drop and it can drop fast. It is the mixing of it with soda, juices etc. that cause it to go up. Example, 1/4 cup of plain vodka has caused my BS to drop over 100 points in an hour!
Overall, your #'s are not bad, but it is in your best interest to eliminate those high fast food numbers as the high numbers is what causes the damage to your eyes, feet and other body parts. Wish you the best in all your numbers! Jim

This is so thorough and very good information for you to start with. The best thing is to work out what works for you with your doctor. But I have to admit, the more you test the more you can learn about what your body does with food, exercise, stress and so much more.

My doctor tells me to test twice a day. Fasting in the morning and before I go to bed. To me, that is not enough and testing before and after meals can give you a lot of information to help you with planning your day out. Keep a log book and write down what you are eating and what your levels do. This is how I found out I cannot eat anything with corn in it, but I can eat vanilla ice cream with nuts. Go figure! LOL

The way to find out about testing after a meal is to test every 30 minutes for a few meals and see when you peak. Generally, people peak about 2 hours after a meal, but that can depend on what you eat as well. What you want to do is find when you are usually the highest to see what is going on. Everyone is different and finding that place takes some practice.

If your levels can be below 140 and above 100 before bed you are in a good place. The reason you may want to test around 3:00 AM is because that is when people tend to drop low. You want to know what your body does while you sleep so you can prepare it with a snack to raise your levels through the night if you tend to drop. I tend to rise during the night, so sometimes a snack at night helps my body realize it doesn't need to give me any extra.

You have some great questions and you are taking charge and that is great! Keep that up and you will be teaching us all kinds of things.

I read your questions and all of the answers. Thank you for clearing up many of my thoughts as a new type 2 also. Great responses. Thanks again.

Yes, 125 is NOT really terrible. I don't become concerned until above 130.

You ask about when you should test. It is generally considered that you should test a MINIMUM of 3 times per day to get the best idea of what's happening with your body: #1, after you awake (fasting BG), and then #2, test 2 hrs ("postprandial") after a meal of your choosing (you can test one day after breakfast, another after lunch and another after dinner/supper) and then just before bedtime. The last one you do so you can know if you have enough "fuel" (glucose) to make it through the night without going low and causing your liver to dump glucose stores into your bloodstream usually making your fasting BGs high in the morning when you wake up.

Not sure I understand your question numbered 1. If I understand your questioning if the meter itself is accurate, it is understood that the FDA standard for glucometer accuracy is they deem acceptable a meter which reads 20% either way of dead on accurate. So if you had 2 meters and you took the same blood and tested at the same time you could potentially have a 40% variation between those meters and the FDA would say they both are acceptable (as I understand it).

The way I look at it, my meter may not be 100% dead on accurate, but what it does is it gives me a trend of what my Blood glucose readings are doing over time. That's why I like to use the same meter all the time, and won't jump from one meter to another unless I must for some reason. I get the idea that my readings are tending higher or are are staying normal, and then I can adjust my eating plan and/or medication regimen accordingly.

Your question number 2, I believe I already answered above. It is better to test 2 hrs I believe. There may be others with different opinions, but that is usually the standard that MDs use.

Regarding question 3, that is a matter of opinion as to what your BG number should be at bedtime. I think it should be somewhere between 130 and 140. One of my PCP docs told me years ago it should be in the neighborhood of 150. You should get your Dr's opinion on it too. You can also keep track of your bedtime BGs and compare them with your fasting BGs and if you have a high fasting (due to liver dump at night) perhaps you ought to bump up your bedtime BG by eating a long digesting carb, together with a protein to keep your BG from going low overnight. Some have suggested a sheet of graham crackers and 2 teaspoons of peanut butter does the trick for them.

As far as what you're eating, chicken is very good, so is fish. I eat a lot of hard boiled eggs, but that's not for everyone, due to cholesterol concerns. And by all means fill up on veggies, except for potatoes, peas and corn. But you might have to rethink the fruit consumption. Generally you will need to let your meter tell you which fruits are friendly to YOUR body and which spikes you big time. We all are different in our reactions to various inputs to our body, so it is best to let our meters tell us which are friendly and which are not.

I pray this all made sense to you. Blessings to you and yours!

James, I wanted to make sure that the BG levels that I listed above as in what is considered "normal range" accurate

Thank you James and everyone else for the wealth of information…I am going to read, read read and try to make sense of all of this. I am sure I will have a ton more questions…

If you check your blood surgar several times a day, you will need to keep a log before the numbers mean anything to your doctor. For example, note the amount of time since your last meal and whether you had been exercising before taking your blood sugar. My doctor told me to check mine only before breakfast and before dinner. Usually the people taking the blood sugar in the middle of the night are people taking insulin or have a history of wide fluctuations in their blood sugar. In terms of whether your numbers are good, I've seen different articles that fasting blood sugar should be between 70-100. Other articles I've seen indicate fasting blood sugar should be no higher than 125. Follow what your doctor says. Your blood sugar will not be affected by a meal an hour after eating. 2 hours after eating, your blood sugar will be affected. Hope this helps.
