I am new to this forum so I thank any of you who take time to read and answer, or comment on my concern. I have had extreme weight gain aprox. 40 lbs over the last 8 months or less. My diet has not changed, and I have even increased my exercise to try to stop the gain. I have never had a weight problem before, even weight gained during any of my four pregnancies, I was able to loose without doing any more then returning to my active busy routine. My doctor has suggested age, hormones, and diabetes testing. I had a thyroidectomy over 5 years ago and take a supplement for that, closely monitered by my endocrinologist. Are there any suggestions of a possible cause, or testing the may give or rule out a cause for this. Thanks again topsy-turvy.
