the corners of my mouth are cracked and dark on the sides of the mouth. Around lips are dry. I have a treated thyroid (hypo - medication taken is Levothyroxine 125mcg). In researching, I believe it to be Cheilitis. I also believe that the cause could be B2 and Iron deficiency. I have been plagued by constipation, my eating habits are not good ( i eat way too many carbs and processes snacks). My T2s & T4s are good however, my doctor said I am boarder-line diabetic. What would you recommend/prescribe that I do to about the symptoms of the cracked mouth corners, the scaling around the area where a goatee would grow?
