Hello, my doctor found that I have "impaired glucose tolerance". My glucose numbers in tests where above >140 after two hours. He prescribed metformin 500mg (which I have been taking for a year). This week my sugar has been around 72 two hours after eating. And I haven´t felt well. The weird thing is that my glucose numbers are very low, and I still urinate very frequently...why is this????
Why are my glucose numbers so low after eating?. I thought it could be that the dosage of my medicine was too high, so I tried going one day reducing the dosage, but the urination got worse.
I feel that if I take the medication, it lowers my sugar levels too much, and if I take a lower dosage, it is not enough.
How exactly does metformin work?

Super_sally888, concerning your question about my sugar levels before I eat. Here are my numbers. Before dinner my glucose was 83. After dinner (1 hour later) my glucose was 128.
I have noticed that below 80´s I feel bad. I have to eat a lot to feel well. Today I ate a plate of rice, melon, peach and turkey, now that my glucose levels are at 128 I feel well.

Hi,

before eating a normal blood sugar will be 70 - 90.

A blood sugar in the 70s may feel low to you at the moment as you are accustomed to having higher levels before the metformin.  However, while at the lower end of normal is not a bad number.  Your body should adjust in a few days.

meanwhile eat small snacks between meals (healthy ones) and your blood sugar should stay pretty stable.

Hope this helps.

When you say that metformin works by increasing sensitivity to insulin, and it doesn´t affect the amount of insulin your body releases, does that mean that my body could be producing high amounts of insulin, which now can be used due to metformin, and therefore my glucose levels decrease too much?

My fasting numbers  are around 92.

I haven´t really measured my numbers before I eat, I will do that. Within what range should my glucose levels be before I eat?

I am eating protein and fat every meal and complex carbs.

What worries me is that I do not feel well when my glucose levels are around 70´s. That is my concern.

Metformin works by increasing your body's sensitivity to insulin, however it doesn't directly affect the amount of insulin your body releases.

A level of 2 hours after eating is not necessarily a concern.  It is normal range.

What I would like to know is what your fasting numbers are.  

Also what are your numbers just before your eat.  This can tell us more.

Try to make sure you eat fat and protein at every meal and not too much carbs this should give you a more steady blood sugar level.
