skin contains elastic fibers that allow it to stretch during weight gain or recoil or shrink during weight loss. so someone who gains a large amount of weight does not grow new skin. their skin stretches to accommodate the accumulation of fat tissue.
during weight gain does a persons skin streach or does it grow to accomodate the extra fat? . i am curious to know if a persons weight gain causes the skin to grow or to stretch. i am already aware that rapid weight gain can cause the skin the tear leaving stretch marks. i am asking more in regards to morbidly obese people that weigh around 400-700 pounds. i am curious to know if the skin actually can stretch that much or if the adult body is forced to grow the skin as it stretches.
