Yesterday my endo decided to increase my dose from 500 mg to 2000mg. He told me to increase it by 500 mg a week until I hit 2000mg provided I'm having no GI symptoms.
So, yesterday I went ahead and increased my dose to 1000mg right after my appointment. Nothing happened.
Then at dinner I went ahead and took another 500mg, bringing my daily total to 1500mg.
This morning I went ahead and took 1000mg right away.
...still nothing. Not only am I not cramping, having gas, or having diarrhea....I haven't even had a BM in two days!!!!
So, is constipation a possible metformin side effect, or do I just have a steel GI tract?
