Testing Blood Glucose?

For the sake of curiosity, I want to start testing my blood glucose. A few questions, if y'all are willing to put up with my ignorance. Feel free to just link me somewhere.

1. Is there actually a great deal of difference between glucometers? (if so, any recommendations?)
2. Are there other supplies I may need as well?
3. What's considered "normal"? What's considered out of range?
4. When do you actually test?
5. Is glycemic index generally the only thing that affects blood sugar?
6. Anything else I should know?

Thanks!

    Some monitors can test blood glucose and ketones. Ketone test strips are MUCH more expensive so look into that before you commit if you end up deciding you want to test both.

    If you are just interested in blood sugar, I'd recommend the Relion brand that's sold at Wal Mart. The meters themselves are all pretty affordable, but the test strips vary wildly in cost. The Wal Mart Relion brand test strips are cheap and more than accurate enough for me. In fact I believe its just a well known brand (precision?) re-branded.

    2. You need a meter, test strips, and lancets (to prick your finger). I hate doing this, in a big way. Personally, I use this multi-clix thing:

    http://www.amazon.com/Roche-Diagnostics-075537661529-Accu-Chek-Multiclix/dp/B003UC8SE0/ref=sr_1_2?ie=UTF8&qid=1429724668&sr=8-2&keywords=accucheck+multiclix

    with these lancets:

    http://www.amazon.com/Accu-Chek-Multiclix-Lancets-Count/dp/B00CJURYXU/ref=sr_1_1?ie=UTF8&qid=1429724668&sr=8-1&keywords=accucheck+multiclix

    I am quite sure this is not the cheapest option, so I would not necessarily recommend these. But the idea of just taking a lancet and stabbing myself with it still freaks me out after 5 years, so I want *something* like this to do it more automatically.

    3. There are two measurements, if you're in the US, the measurement is mg/dL. A normal fasting blood sugar would be 60-100. The other measurement you can take is 1-2 hours after a meal. As a diabetic I believe the ideal goal is to see this number not go above 140. As a keto dietier, in reality, I expect this number for me to never go above 115. If youre not in the US the measurement system is a bit different and yoiu're talking about numbers in the 4.0-7.0 range using a different scale. I only know that scale as it relates to the A1C I get at my doctors office every 3-6 months. Many doctors seem to say below 6.5 for a diabetic is ok, but I believe the standard should be much lower than that even for a diabetic.


    4. If you're looking to learn as much as posible and collect data, then take your blood sugar when you first wake up (fasting, before any food/coffee/whatever). Also take it 1-2 hours after each meal. If you eat 3 meals a day that could mean testing 4 times a day and you're gonna get tired of sticking your fingers and test strips, even the cheaper ones, can start to add up in cost. So maybe do that at first to learn how your body normally acts, and then adjust once you figure out what you want to do.

    5. TONS of things affect blood sugar, its unbelievable and as a diabetic its incredibly disheartening at times to realize how hard it can be to manage blood sugar. Its the reason I'm on keto. Without keto its just too damn hard. The biggest things though, are sleep, activity, and stress. Lack of sleep can cause your blood sugar to go up. Activity can cause a sharp rise in blood sugar (followed by a bit of a crash... well, probably not on low carb, but this was a constant issue for me pre-keto). Stress causes all kinds of things to happen with hormones, and one of the big ones can be blood sugar increases.

    6. Nothing else i can think of!

    I use this link to help me with what is "normal." http://www.phlaunt.com/diabetes/14045524.php This gives an excellent way to lower blood sugar as well as find out what triggers spikes. Its different for everyone. I use One Touch Ultra mini, I think. I would like to try something different but my insurance covers this brand only. It works but I'm starting to think it gives me a higher reading than what I get at the doctor's office. I generally only test in the am before eating but I keep my meter in my purse in case I feel off throughout the day and need to test. I also occasionally test 1-2 hours after eating something to test the effects.

    I too use the relion brand from walmart, i used one for years when I had a cat that was diabetic and it was always really easy to use and affordable, always check the cost of strips before you buy a meter, some can be a lot more than others.

    I think I'm going to run by Walgreens and get theirs (the TrueResult: http://www.walgreens.com/store/c/walgreens-trueresult-blood-glucose-monitoring-system/ID=prod6098626-product) after work. I would do the Walmart one, but they just shut down one of the Walmarts here & the other one is a ZOO, especially near the pharmacy. This one comes with the lancing device, lancets, & control solution. If it's the same one that comes with the TrueResult meter on Amazon, people like that lancing device.

    No doctor's recommendation for this, so no insurance paying for it (probably wouldn't cover it on ours anyways, at least not until we hit the deductible!). The strips from Walgreens are about the same price as the ones from Walmart.

    It's going to basically be a way for me to prove to myself that what I eat does affect me whether I want to think it does or not.

    1 more question: they say store at room temp. Anybody ever have one fail because it can't take 110 degree heat outside, or is it just the standard electronics warning?

    Off the hip, I would guess it is the strip that needs the more moderate temperature...because those things are chemically set up to give accurate results...

    Playing with it, reading is 77mg/dl. I figure I'll try 1 and 2 hours after dinner, especially since it will be heavy on carbs tonight.

    77 is damn good! I wish I had a reading as low as that!

    This thread helped me out quickly. I took my glucose and ketones in a fasted state this evening and they were 73mg/dl for the glusoce and 2.1mmol/L for the ketones. Then after I ate I checked my glucose and it was 97mg/dl 1 hour later and 84mg/dl 2 hours later. All those numbers look good to you guys who have experience with the blood testing?

    Be sure to clean the sot you're going to prick. I did it once forgetting that I'd recently put hand lotion on. It read 142. Washed my hands and it read 106. Evidently my hand lotion has sugar in it????? The meter is really handy to see if a certain food spikes your blood sugar. I take a reading before I eat whatever it is, then an hour later to see how I'm handling it.

    Those are awesome numbers! :)

    @Twibbly One other thing to keep in mind is the dawn phenomenon. Everyone gets it, but metabolically sound people won't see great differences in blood glucose. However, if you have metabolic issues, this can increase your morning fasting number, especially if you test early in the morning.

    There is also the somogyi effect. Dawn phenomenon is a normal waking response (via hormone production - getting ready for the day, so you get up), generally dealt with by the body producing more insulin to combat the glucose increase. Some of us don't do that well enough, as Dragon pointed out and we end up with higher morning numbers. Mine vary quite a bit. Its frustrating.

    Somogyi effect is basically when you drop too low (kind of a hypoglycemic state), and your body will again squeeze out those hormones to combat the low glucose, and this can result in morning highs also.

    Different issues, same ultimate result. If you have higher morning glucose, in order to determine which issue you actually have, you have to test before bed, around 3am, and again at waking time. Dawn Phenomenon you can't do much about...Somogyi is oft helped by small protein/fat snack before bed to tide you over.

    Agree with radiii...so much effects glucose levels. sleep, stress, emotions, food, activity, lack of activity, alcohol consumption...on and on. Last night I ended with a reading in the 70's postprandial. Today, I cannot get below 112. I ate virtually the same food and did the same amount and type of exercise. It irritates the hell out of me, to be honest. High glucose and high ketones are generally mutually exclusive for me also. Yesterday I was reading ketones over 2.0 all day long...2.9 in the morning (when they are generally lowest). today, I peaked at 1.6 10 minutes ago. go figure.

    Some of my best morning readings have been on saturday and sunday mornings....because I'm home on the weekend, and will have a couple of vodka/seltzers in the evenings. I figure my liver is too busy metabolizing the liquor to bother squeezing out glucose in the middle of the night...at least thats what I tell myself...lol :tongue:

    So, I should have listened about the Walmart meter because I can't get cheap strips for the Walgreens meter except online. So, I got the Walmart one as well.

    Is it normal for 2 different meters to be 30 points off from each other? Same finger poke and everything.

    Oh, for those who are interested:
    3hr before/after food: 79
    1hr after food: 130
    2hr after food: 108

    Those numbers are from the Walgreens meter. The last number, from the Walmart meter, was 136!

    Everything everybody said is good. I can only add that if you pick the same area on the fleshy side of the last joint of the same finger, eventually it won't hurt as much as it deadens the area from all the punctures. I hate pricking my finger much worse than the insulin injections. BTW, they say to swab your finger with an alcohol wipe, ~ I have never done that in the 13+ years I have been a diabetic. I do wash my hands and rinse and dry very well though. The meter reads a particular electrical resistance, so if you have any foreign liquid, dirt it will affect the reading.

    If you want to check if your liver is dumping sugar at night into your blood stream, (very common among diabetics), eat at 6:00 pm and don't eat or snack until the morning. Check your BG right before you go to sleep, then as soon as you wake up. It may go up (mine would go up 10 - 30 points pre-keto).

    I so agree with @Radiii, that Keto has made life so much better, insulin and diabetic meds are a horrible way to control blood sugars.

    Here are what my sugar levels were pre-keto...taken from a program I used with my meter. The highs were about 460, the lows were about 30. The green area is normal BG levels. Unfortunantely, I don't have any "after" graphs because I gave my meter to a friend. When my BG levels got below 150, I was so happy, I quit checking. :)

    This morning, pre-coffee: 110 on the one, 136 on the other. I think I'm just going to use the Walmart one and assume it's 30 points over due to the fact that I can get the strips for cheap locally.

    Dan, thanks for the tip about using the same part of the same finger. I was figuring it should be spread out so they all hurt evenly. :wink:

    I'll try the measuring at night and then in the morning at some point.

    Woohoo, coffee with butter does not make it change at all. I know it theoretically shouldn't...but that doesn't mean I'm not curious!

    OK, my metric geeks. How do you track your BS and what affected it? I plan to track the Ketonix readings as well, once I get back to behaving.
