Abnormal OGTT Results - The many causes

direct image link

As often happens, when looking for something a bit more specific, I came across this image at right, which led me to this webpage:  Laboratory Testing for Diabetes Mellitus.

Curve 1 is a normal OGTT, Curve 6 is a diabetic.  The other causes are listed:

Pathologic conditions causing impaired, or diabetic, glucose tolerance results:

• Hypercorticism - curve 5.
• Acromegaly - between curves 4 and 5
• Hyperthyroidism - curve 4.
• Pheochromacytoma (or "emotional hyperglycemia") - between curves 4 and 5

Puzzle Pieces ... Low Carb & Thyroid

So ... it' been a while, almost a human gestation period, since I reported my miraculous selenium insomnia cure.  In a nutshell, I started taking Se to see if it might help and within days I was sleeping like a baby through the night.  Although I found adding starches in somewhat difficult at first, I've also recently made clear that I'm eating a good 100g/day most days now ... at least that would be the average ... for starch.  I still eat a lot of veggies that I don't bother counting the carbs in and fruit several times a week, so probably getting about 150g perhaps up to 200 total grams of carbs these days.

Cysts and Hypothyroid ~ Any Info?

Hi all.  I'm hitting a brick wall trying to find any info on this and am wondering if anyone with hypothyroid has ever heard of this and/or might steer me in the right direction.  Searching on cysts and hypothyroid I keep getting info on cysts on the thyroid which is not my concern.

My mom injured her knee several months ago, and initial x-rays & MRI revealed, amongst torn this or that, a Bakers' cyst.  A few weeks ago she slipped and jammed her wrist breaking her fall.  No break, thankfully, but her doctor asked her if she had any thyroid issues that she was aware of.  I asked him why he would ask and he said it was because she had several small cysts in her wrist.  Apparently (ortho surgeon) he said this is common in people with hypothyroid.  

Is it?  Anyone know why?  Thanks in advance!

Low Carb & Hypothyroid ~ Healthy?

It is very difficult to find peer review studies on thyroid function and the effects of a low carbohydrate diet.  I've found a few short term studies, but nothing long term.  It would be nice to have longer term studies on VLC, but there's just not a lot of people going to be willing to follow such a diet for a matter of years in a study.  So if anyone is aware of any studies that might be relevant, please do provide links in comments.  What I'm particularly interested in is the second half of the first year - e.g. months 7-12 - and beyond.  Because anecdotally, this is the time frame when hypothyroids seem to react rather poorly to a VLC diet.  Far more material is available on health and nutrition related sites.  While I prefer not to rely on such sources, I think the information available from reasonably reliable sources demonstrate that carbohydrate restriction reduces T3, reduces T4-to-T3 conversion and increases reverse T3 (rT3).  The latter happens with all diets but the T4-to-T3 conversion differences I've seen reported are reductions in the 25-35% range with VLC diets.
