It’s no secret weight gain and overeating is an issue during the holiday season. Studies show many people start to gain weight in October, and the trend continues into January. Most individuals gain an average of 1.5 pounds during the holiday season. But it’s not just the weight gain that causes issues. Overeating affects the body in a variety of ways. It makes the digestive system work harder and can also lead to organ issues, as well. If overeating becomes a pattern, there are long-term consequences.

1. The Stomach Expands

A normal, adult stomach holds about two cups of food. The stomach is about the size of a fist when empty. When an individual eats too much, the stomach stretches beyond its normal size to allow room for the additional food, similar to the way a balloon expands if overfilled. The stomach presses against other organs, leading to discomfort and a feeling of fullness. The muscles in the stomach work harder to keep the food in place for the digestive process. However, after several months of overeating, the stomach muscles become accustomed to the stretching required and it takes more food to achieve a feeling of fullness.
