I have been prescribed glyconet500SR on present reading of 150/216 FSB/PPBS. Diognosed with glucose intolerance in 2006.Was controlling sugar levels by diet .During these 6 years periodic check ups sugar levels sometimes showed beyond the normal range. Recent upsurge may be because of liberty with diet. Whether the drug is to be taken before or after food. And can the drug be withdrawn after normalcy ?
Hello, Mr Mehta.

With this sugar reading one is called to have overt diabetes. You were having glucose intolerance till now but now you have type 2 diabetes for sure.

My daughter is 16. She has been diagnosed with hypothyroidism, sinus tachachardia, chronic costas chondritis, glucose intolerance, and low vitamin D. She takes levothryoxine, sulindac and metformin daily. She has struggled with chest pain for 4 years. She has seen cardiologists and general physicians. Is a rheumatologist the next step? She needs to get off these drugs and be able to be a normal teen that is not in pain all the time. Have you ever heard of a kid with this costas chondritis that cannot be cured?

I recently had a glucose intolerance test at my neurologist , who claims to know little about hyopkelemic perodic paralysis . After the 3 hour test, I went into a full episode of paralysis lasting 5 hours in his office. I did have a low potassium level the last time they cheched my blood (4), although he says it is not low enought to diagnose me. I am now 53, and have with years of frustration thinking I was not able to walk because I had fibromyalgia for 25 year. My family can trace back episode from when I was a young child. My brother has symptoms and also my son. I simple do not know where to look for help in the Memphis, TN area. I have been working to find answers for 4 years as I get shuffled around so that the Drs may make their 20 patient a day goal. I have had some results with a caring ENT that will not perform sinus surgery on me until I am under a Dr s care. He said surgery for me could be life threading at this point. Any guidance in the mid south or mid west for an appropriate Dr would be appreciated

Based on details you have hypokalemic periodic paralysis with positive family history .This indicates primary hypokalemic periodic paralysis ( gene defect for channels located at skeltal muscle) rather than secondary causes .

Still you need detail evaluation like calcium, magnesium levels in...

My friend had PCOS a long time ago, and SLIGHTLY high blood sugar... after testing, the doctor said, 'we can knock out both with metformin, and she went on it in '06). PCOS disappeared and little changed medically... and then she became pregnant very soon after that. With that pregnancy she was diagnosed with gestational diabetes and went on insulin. After that(Mid '07) she went back to metformin... in late 2009, she was still on metformin but doing great. She went off metformin in (Sept. '09) and her blood sugars were great... never over 115, usually 100 or lower, which she had previously been told she could never do again because 'once you have glucose intolerance your always diabetic'. ( I should clarify this by stating she has NEVER been diagnosed type 2, she was found to have impaired glucose tolerance)
Well everything was peachy until this august, early September... after a year of good health her blood sugar started rising... avg of like 140 to 150 and she was getting lethargic, so she had to go to the clinic...(no insurance) Once she revealed she had been on metformin(a year ago) the doctor prescribed her more and said he was sure it was just early diabetes... then gave an A1C on which she got 5.7... She has NEVER had an A1C over 7... either way the doctor didn’t care to figure more out... well now we're in the spot where she feels awful and her blood sugar is even HIGHER after taking metformin for a few months again. (160 to 190) So this leads me to ponder a few things...

1. If she is diabetic, how was she super healthy for a year, scored an A1C of 5.7 and didn’t even feel to sick, mainly just lethargic when her blood sugar began to rise..?
2. If she isn’tt diabetic, is taking the medicine causing unnecessary problems like that lactic acidosis (lf I'm not mistaken, metformin is known to cause).
3. Is there a chance its thyroid related?.
4. What vitamins do you recommend for this sort of issue?

Food intake: Shes make a lot of our own food, some even from what we got out of our garden.
Water intake: She doesn’t usually drink as much as she should, she says she just never feels thirsty, and hasn't since child hood. Although she is working on drinking anyways...
Exercise: She is not overly active, but not a total bum.. so moderatish( we have 3 kids to take care of)
Oddities: as I stated, Sarah has never really felt thirsty, also strangely, on metformin she is now craving MORE food, especially sweets, even though metformin is used as an appetite suppressant... this side effect was not present when she was on metformin in the past.

Any advice on this issue would be much appreciated.

Thank you very much.
