I have been constipated on a consistent basis since the onset of winter weather. Also lost 2 lbs without dieting but I also am on a thyroid medication. Could there be a link between these issues?

Thryoid&constipation. Hypothyroidisnm per se can cause constiaption. If you are newly diagnosed, then maybe u need fine tuning of the medication dosing. Speak to your docotr about the cosntipation.
Possibly. This is one of those problems where a visit to your doctor is necessary to figure out what's going on. Only after a thorough evaluation, including examination and possibly labs and other tests, can your doctor correctly diagnose you and treat you effectively.
