My A1c History

A1c testing was not available until 1976. My doctor started A1c's with his patients in 1980. I was diagnosed in 1945 when I was 6, and I must have had very high blood sugar until about 1988. That is when my A1c's began improving. Now I am alive after 71 years of type 1, and I have no complications except for some mild nerve damage. As part of my preparation for my taking part in the Joslin Medalist Study I was supposed to have a listing of all my A1c's. My doctor was very cooperative, but there are several gaps in the list.The years 1990-1994 were not available. Below are the A1c's that my doc was able to retrieve from his files. I have updated for 2013-2016.
1980...10.6, 9.6, 9.0
1981...11.8
1983...9.2
1984...9.2, 9.7, 8.9
1986...11.1
1987...8.0, 9.8, 10.3
1988...10.5, 7.7, 7.7
1989...7.3
1995...6.8
1997...6.0, 5.4
1998...6.5
1999...6.8, 6.7, 6.5
2000...6.3, 6.1, 5.5
2001...5.8, 6.0, 5.6, 6.0
2002...6.0, 6.4, 6.2, 6.0
2003...5.6, 5.4, 5.9
2004...5.9, 5.7, 5.8, 5.6
2005...5.6, 5.8
2006...5.6, 5.7
2007...5.5, 5.6, 5.7, 6.1
2008...5.7, 5.9, 5.7, 5.6
2009...5.6, 5.8, 5.8
2010...5.7, 5.6, 5.6, 5.4
2011...5.6, 5.7, 5.8, 5.6
2012...6.1, 6.1, 6.0
2013...5.8, 6.1
2014...5.7, 5.6, 5.8
2015...5.8
2016...5.9, 6.0, 6.1
Notice the drop from the 10's to the 7's in early 1988. That is when I
read an article in a magazine that said diabetics should follow a low
carb diet. My doctors never told me that. Then in the late 1990s I was permitted to use basal/bolus control. In 2007 I started pumping. My A1c's have been very good during the new century because I finally knew what to do to get good control. I was very successful for several years before pumping too, but using an insulin pump has made good control so much easier.
I took only one injection of beef/pork insulin per day during my first
35+ years. Can you imagine what my A1c's would have been during those years? Those were the years before my doctor started having my A1c's done.
I feel so lucky to be alive and healthy, without serious complications. Is it good genes? The Joslin Study of long term type 1's in the Us has reported that many of the participants are still producing some insulin. Those individuals are insulin dependant, but any amount of insulin produced in our bodies is very beneficial in helping to prevent complications. My C-peptide is less than 0.1, so I am producing almost zero insulin. There has to be some other explanation for so many of us living so many years with type 1, and not having any serious complications.
