Why is it harder to breathe after a big meal?

After a big meal, the stomach expands to accommodate the food, which can push against the diaphragm, the muscle that helps with breathing. This pressure can restrict lung capacity and make it feel harder to take deep breaths. Additionally, digestion requires increased blood flow to the stomach, which can divert blood from other areas, including the muscles involved in respiration. As a result, some people may experience a sensation of breathlessness or discomfort after eating a large meal.
