Hi fellow diabetic and GD moms,

I've had gestational diabetes through two pregancies and just had to be put on insulin for the second in spite of the fact that blood sugar levels are mostly within range and the baby's size appears to be normal. I wanted to share my story to alert fellow moms to a concern about managing your ketone levels. As most of you probably know already, your body spills ketones when it does not get enough carbs, or if your body is not producing enough insulin to help your body process the carbs correctly and carry them to the baby. Most doctors (even mine - and I go to a maternal endocrinology branch that specializes in pregnancy-related diabetes research) will only tell you to check ketones first thing in the morning. Because of the overnight fast, that is supposed to be the time when you are most likely to spill ketones. Otherwise, they tend to assume everything is okay.

In my case, even though I did not spill ketones in the mornings, I started testing a bit more frequently and found that I was regularly spilling ketones (sometimes trace or small, sometimes moderate or large) every afternoon - a time when I wasn't alerted to the need to test. Apparently my body wasn't producing enough insulin during a normal day's activities to process my lunch carbs correctly. I never would have known the baby was getting ketones every day (sometimes at pretty high levels) if I had not started testing more frequently than recommended. While the research available on the impact of spilling ketones is still limited and the recommendations about ketone testing vary, my hospital participated in a long-term study of children who were born to diabetic moms that found a correlation between moms who regularly spilled ketones and lowered IQs of 10-15 points. Even if the jury is still out on best practices to manage ketones, I feel reassured by being proactive and taking precautions just in case. Testing for ketones is simple and relatively low cost. Adding in an occasional afternoon or evening test just to see if you have any similar issues (even if your doctor doesn't tell you to do it) may alert you to potential problems that you should discuss with your physician, as it did me.

Chicago GD mom,

Great post! I think it is really good to think out of the box like this, and test to know what is going on in our bodies. As proactive patients we can sometimes discover patterns that our doctors may not know about yet.

About three years ago, I was reading more details about MODY3 and lowered renal threshold. I had been having a lot of Traditional Chinese Medicine symptoms of low "kidney system" energy - in fact my period was sometimes 70 days apart. I decided to start checking my urine readings throughout the day. I mean who checks urine glucose any more, right? I discovered that with my doctors recommendation of 180mg/dl post meal readings - I was spilling sugars in my urine almost all day. I figured out my renal threshold was about 150-160mg/dl - so I set my own post meal goal to be 150mg/dl. It made a significant difference in my health after a few weeks.

Then last year after reading Jenny Rulh's book, I lowered my post meal goals again to be below 140mg/dl in accordance with the ACE guidelines!
