During digestion, blood flow is redirected from other parts of the body to the digestive organs to allow food to be broken down and absorbed.
After a meal, our parasympathetic nervous system also turns on, aimed at relaxation and promoting the redistribution of blood to the organs of the gastrointestinal tract.
Accordingly, flowing to the gastrointestinal tract, it moves away from the brain.
In addition, with it, oxygen leaves. Hence the desire to sleep.
Simple carbohydrates, such as those found in refined sugar, candy and carbonated drinks, are quickly broken down by the body and cause a spike in blood sugar.
This can lead to a subsequent drop in sugar levels, leaving us feeling tired, sluggish and irritable.
Heaviness in the stomach is an unpleasant sensation that occurs both due to poor nutrition and due to diseases of the gastrointestinal tract.
Quite often, the main cause of heaviness in the stomach after eating is the ingestion of a large amount of food, which is difficult for the stomach to “cope” with.
