What changes in the processes of digestion in the small intestine does alcohol cause?

1. Alcohol causes a very strong decrease in the motor activity of the digestive tract, and especially the small intestine. Accordingly, this leads to a deterioration in the absorption of proteins, vitamins and carbohydrates.
2. Under the influence of alcohol, the walls of the small intestine change their structure at the cellular level. As a result, the absorption of nutrients in the small intestine stops, which leads to depletion of the body.
3. There is an increase in the permeability of the intestinal walls, through which toxic substances and undigested protein compounds enter the blood. Some of them are classic allergens, which is why many people develop allergic reactions like hives when drinking alcohol.
