A fairly common side effect of noticeable weight loss is flabby or "sagging" skin. In fact, more than 70% of people who have worked on significant weight loss have this problem. Although this is quite normal, it creates a lot of inconvenience.

Flabby skin can be painful because it can pull or irritate your skin by rubbing. Excess skin can even interfere with exercise and any physical activity. So while weight management encourages people to exercise, flabby skin is not entirely desirable.
