I was diagnosed with low iron and since taking iron supplements under the care of a physician I have lost my appetite and lost 25 pounds. Is there any connection?

There are possible connections. You did not say if you were overweight to begin with, or what your activity level is habitually. You may be feeling better because of your iron supplements, be able to exercise more, and feel like doing more instead of just eating and sitting around.

However, the Appestat (the combinations of functions that control appetite) can be inhibited by diets with too little zinc. That can diminish the senses of both smell and taste and therefore undermine the appetite. Zinc absorption may be inhibited by eating a lot of bran, taking iron supplements or by drinking too much alcohol.

Any sudden loss of appetite that does not go away in a few days should be discussed with your physician, even if the effects (such as weight loss) seem beneficial. Clearly, if you have lost 25 lbs., this has existed for longer than a few days. Call and make an appointment.
