What can I do about the extra weight gain only in my face and chin?

If your height/weight ratios are normal, what you are describing is not normal, particularly the fluctuation."Stress" and "water retention" are such common "reasons" or excuses, I would consider a more thorough evaluation by a concerned physician. Facial or submental liposuction do not cure abnormal physiology, and do not eliminate stress or fluid retention, nor will any operation change your normal cyclic hormonal changes, which can play a role here also.I suggest an endocrinologist. See if your family physician or Gyn can refer you to a good one. Best wishes! Dr. Tholen

Hi, It is possible this is accumulated fatty tissue, but I can't really say without an exam.  This is a common site for our bodies to store fat.  You would want to see a PS for a consult.  See the web reference below explaining this.  All the best,Dr. Joe

Without pictures, it's hard to tell what's going on. It's possible for weight gain to manifest under the chin. You might be a good candidate for submental liposuction to improve your jowls and neckline. Find an experienced plastic surgeon, preferably one who specializes in facial surgery, and get a consultation. I wish you the best.
