I have been searching to see if it is possible to influence the hba1c test. I am due an op for bariatric surgery in nov/dec and have recently found out that if my test is above 67, my op will have to be postponed until I get my average result down. I might add that my hba1c was at 54 until the doc meddled with my meds.
When my daily bg went through the roof he apologised saying he didn't know how I would react to the change in meds?!
I'll explain... I was taking 2000mg sr metformin per day, leaving me controlled at 54. He decided to half my dose and give me 5mg of forxiga. All that did was send my bloods through the roof, into their 20s and give me thrush for 3 months. And a hba1c of 63!
Anyway background over!... Lol. To try to influence my hba1c for my test that is due he has put my metformin back to 2000mg and taken away forxiga and also introduced 40mg of gliclazide - my daily bloods have reduced, going from 16/17/18mmol/L down to 6/7/8mmol/L in a week!
I have my test in 10 days so based on this info I am hoping my results are good x [SMILING FACE WITH OPEN MOUTH AND SMILING EYES] .........

Many studies have shown that HbA1c is an index of average glucose (AG) over the preceding weeks-to-months. Erythrocyte (red blood cell) life-span averages about 120 days. The level of HbA1c at any point in time is contributed to by all circulating erythrocytes, from the oldest (120 days old) to the youngest. However, HbA1c is a "weighted" average of blood glucose levels during the preceding 120 days, meaning that glucose levels in the preceding 30 days contribute substantially more to the level of HbA1c than do glucose levels 90-120 days earlier. This explains why the level of HbA1c can increase or decrease relatively quickly with large changes in glucose; it does not take 120 days to detect a clinically meaningful change in HbA1c following a clinically significant change in AG.
