„Bingo wings” is a colloquial term used to describe the loose, flabby skin and excess fat that
may appear on the underside of the upper arms.

As we age, our skin gradually loses elasticity due to a decrease in collagen and elastin
production. This can result in sagging or drooping skin, including the upper arms. Some
individuals may be genetically predisposed to having loose skin or a tendency to store fat in
the upper arm area, making them more prone to developing bingo wings. Hormonal
imbalances, such as those experienced during menopause, can affect the skin’s elasticity.
Significant weight loss followed by weight gain or fluctuations can lead to its development.
