Just another point, the A1c can also be affected by medical conditions that affect the lifespan of your red blood cells such as some types of anemia. Be sure to check with your docs, I may be unreliable to follow an A1c in your case. There are other tests that may help as well as your blood sugar log/average. Good luck!
I have been wearing a pump for 7 months now and the control it gives me is far superior to the lantus and humolog injections I was using. There have been no dramatic highs and not a single low. For me, the pump is the best choice I ever made. However, diabetes is a very person specific disease and you have to find what works for you.
I manage to keep my A1c's around 5, but that doesn't mean I don't have occasional highs and lows (up to 400, and down in the 30s). However, when my doctor switched me over to Humalog and Lantus, I was suddenly all over the place, very high to very low ... After switching back to my usual Humulin R and Humulin N, I was able to get those peaks and valleys under control. I believe it has to do with the VERY fast-acting nature of the analog insulins like Humalog. They hit you almost immediately, for all they're worth, and have a much shorter, less drawn out duration than Humulin, which is a DNA derived insulin, very closely mimicking the insulin your body would be producing naturally, if it could.
That said, you just have to check your blood sugar frequently (I check 7 to 10 times a day--when I get up in the morning, before meals, a couple of hours after meals, before bed, and anytime I think I might be too high or too low), and be willing to take very small adjustment injections throughout the day. (I take anywhere from 5 to 8 insulin injections every day.)
So, if injections are difficult for you to administer, or if you avoid taking injections because you just don't like them, a pump MIGHT be a good idea, but, at least for me, I'm able to keep much tighter control by frequently checking blood glucose, and administering injections as needed.
I've been a type 1 for over 25 years and have managed to stay in the low 6's on the ac1 tests. I use lantus, humalog, apidra, which is fast acting and brings high glucose numbers down faster then humalog and symlin, another injectible that surprisingly most diabetics don't know about. It replaces another product that the pancreas no longer produces and has been essential for me in keeping control and weight down. I do hit highs and lows regularly. A 450 does occur, as does 30's. Testing alot and using the right doseage and injectible allows me to maintain good numbers, regardless of the swings. I don't understand why all type 1's are not on symlin and aware of the benefits of taking apidra from time to time. Pumps never provide the range of control that multiple injections and testing can provide, nor do they allow for all the right injectibles to be used, if used exclusivley.
A few things. First, an A1C is not actually an average of blood sugar. It is the amount of sugar sticking to cells which are placed every 10-12 weeks ish. Then the lab correlates that to an average. Just a correlation, not a magic average.
Second, if you are taking two Lantus shots and one large shot per meal as most people are taught, I'm not at all surprised you're all over the place. That's not the way a non-diabetic body works.
Third, you can regulate blood sugar better without a pump and its costs and risks. It's smaller shots, more testing, small adjustments, retest and NOT eating a high carb diet as recommended by 99% of the diabetes know it alls. I oversimplified but the point is it can be done.
The solution is not the tool, it's the method. Yes, I have one. No, I don't like it. It's nothing but a convenience for other people so they don't have to see syringes so often. My A1C is in the 5.0 ballpark without swings to 600 every day and without constant lows. Doesn't matter what I'm using to infuse insulin.
I became type 1 suddenly at the age of 63. I've been on a pump for over two years now. It definitely helps.
As for your fluctuating BG readings. Are you watching the glycemic index of what you eat? I simply can't get away with high glycemic foods. No more breakfast cereals-even the healthy ones. As long as I stick to mid to low clycemic foods and make sure I wait the full 15 mins after insulin before eating, I stay pretty level. High glycemic food make me soar into the too hight levels and then the insulin hits and I crash.
Your A1C is not always the best marker for your controll, it is an average of your glucose levels over a 90 period. I would guess based on your info that you are having a lot of lows, which is giving you that A1C #. I have been on a pump for about 4 years now and I would never go back to my old injection routine. The pump is the best tool I have everr used to control my diabetes.
