Type 2 Biphasic curve

[AuditKitty]

HI, Can I start out by saying a big thank you to everyone on here. Although I don't post I do log on frequently to learn from you wonderful people and get inspiration to keep going (or get back on the horse after falling off which I did last year after my brother died). I really don't know where I would be without this forum as I was just burying my head in the sand until I found it, so a very heartfelt thankyou to you all.

After going back up to 74, I brought my a1c down to 68 within a month and 3 months later it was down to 49. I am hoping for even better when I go back for my check up in the new year.

I started wearing a cgm again a couple of months ago to see if there were any issues I needed to iron out before my next check up to help me try and at least get into prediabetic range. However, i have noticed since my blood sugars have started to come down that I am getting a double spike after eating - goes up as expected, starts dropping within the hour then starts climbing again, but will return to acceptable levels within 2 hours of eating. I have tried looking this up on the net and apparently it is called a Biphasic Curve, but I can't find any articles about it that explains it in plain english

Does anyone else experience this or could someone explain why this is happening (in simple terms) and is it a good thing or a bad thing?

Hi @AuditKitty
First of all I would like to congratulate you for regaining the motivation and managing to gain better HbA1c levels following a period of personal stress after bereavement.

I don’t tolerate a CGM, so can’t offer any insight from personal experience. The Biphasic curve is a concept I had not heard of before, and it seems the study of this has been facilitated by data from CGM users. From what I have read, ( I confess I have just had a quick scan of available info) it appears that there is no definite conclusion as to the cause, and whether or not it is beneficial. Possibly due to the variables of the participants in the studies? For example, age, diets, atype of diabetes, whether or not obese. It looks as though more research is required? Something to look out for.

In the meantime, in your situation, I would concentrate on doing whatever it is that has brought your BGlevels down , rely on the HbA1c and day to day info from the CGM to be aware of anything that raises your levels more than is acceptable to you, and celebrate your success, so far. Also be optimistic that you appear to be on the right track. Well done for your achievement, and for raising the subject, here, of the biphasic curve.

I will certainly spend some more time exploring the concept. It is very interesting.
