Impaired Glucose Fasting

About a year and a half a  year ago, I was diagnosed with impaired glucose fasting, fasting glucose level was 119.  At that time I was complaining of constant thirst, frequent urination, and sometimes night sweats, and slow healing.  6 month follow-up (one year ago) the fasting glucose level was 113.  A1C was 6.0
I have been modifiying diet, exercising frequently and have lost approx 10-12 lbs.   (Most of this in the last 3 to 4 months)  Follow up testing yesterday showed fasting glucose and 2 hour glucose at 93 and A1C level at 5.9.  I don't have insulin values for you but if needed, could get them.
My question or concern is this.  I still have the thirst issue, as well as frequent urination problems (although not daily), and sometimes night sweat issues.  Although I have managed to get glucose numbers down to normal ranges through diet and exercise, is it normal to continue to have the other symptoms?
Will that dissipate with continued management of glucose levels?

I commend you for your diligent efforts with controlling and lowering your glucose back to normal levels. That's a big attaboy! I'm not certain how to answer your latest and ongoing concerns directly. Perhaps you could answer all of my questions first to give me a general direction to point you towards.
1. If you pull back your bed covers, do you see body hair on your sheets?
2. What color is your urine?
     * Clear like water or more towards a coca cola darkness.
3. When you sweat at night, is it light or more towards heavy sheet soaking bouts?
4. Are currently taking any medication? Supplements?
5. Explain "frequent urination problems"?
    * How often during the day? Night?
    * How long after drinking liquids do you have to go?
    * Does this happen after bedtime?
I look forward to hearing from you.

In response to your questions-
1.  No hair loss
2.  Generally dark in color, but not cola colored,
3.  light, enought to dampen a t-shirt, but not soak it, and no sheet soakings.
4. No meds or supplements.
5.  As often as 6-8 times a day or more, Generally always in the day-time.  Often with minutes of starting to eat, especially at breakfast time and sometimes lunch, Almost never happens after dinner.  Sometimes wake up about twice during the night about 12-2 and then again around 5.  After going around 5, usually have to go again around 6 or 6:30, with no liquid intake.

I'm no doctor but if I were in your shoes I would ask your doctor for the following labs:
1. ALP (alkaline phosphatase) check for liver problems and bone issues, like tumors.
2. ALT (SGPT) and AST (SGOT) check for liver problems
3. Creatinine, serum checks for kidney issues
4. Hepatitis A, B & C
5. CBC complete blood check

As part of the most recent blood labs, CBC and kidney checks were done, nothing noted.
I've also been vaccinated for Hep A & B.
Thanks for the suggestions and for taking the time to look at my question.
