32 y/o male, when your consuming foods and the food enters your stomach, why would one feel bad abnormal contractions through out your lower g.i. tract right after consuming food not in stomach but lower g.i. tract with non stop gas/air all day .?

When food is eaten and goes to the stomach, it then moves out of the stomach. When it moves out, it triggers the food and feces further along the GI tract to move as well. The amount of gas and air is typically relative to a combination of how long the contents have been in your body - the longer is more gas and how much carbohydrates were in the food you ate - the more carbohydrates the more gas.

There is a reflex called the gastrocolic reflex, in which the act of eating triggers contractions in the colon to help empty the colon. This is entirely normal, and it is the body’s way of emptying the bowels appropriately for more food to be taken in. Good luck.
