Stomach Upset-Overeating

The human stomach holds approximately one liter of food. If you over eat, which most
people do, your stomach can expand to hold up to four liters of food. When the stomach
expands to accommodate this additional volume of food/drink you feel bloated and may
experience stomach upset.
When the stomach expands it pushes up against your diaphragm causing shortness of breath
or labored breathing.
Pain in the upper or lower abdomen, nausea, belching, “gas” pains, and feeling bloated
are all symptoms that can occur as a result of overeating.
Since the volume of food/drink you have in your stomach is too much to handle, your
stomach begins to produce more acid to help digest the food. This extra acid production
may weaken or relax the (lower esophageal sphincter [LES]) which is a tight band of
muscles at the lower end of the stomach that prevents food from travelling back up the
stomach and toward the throat. If the LES starts to not work properly stomach acid
begins to travel through the esophagus(the tube that connects your mouth to the
stomach).
