How The Digestive System Works, How Food Is Digested?

The digestive system is a collection of the organs that work together to digest the food and drink which you take. The process of digestion starts from the mouth, where food is broken down into small pieces so that it can easily be swallowed. This semi-solid food travels down towards the stomach and intestines via peristaltic contraction in the esophagus ( a food pipe).

Any type of food (carbohydrates, proteins, or lipids) which you are taking, are digested and turning the nutrients into energy (in form of glucose or ATP) that the body can store for future or use for body functioning.

Gastrin and secretin Hormones are produced along with acid production in the stomach to digest the food. This digested acidic food now moves toward the intestine where bile juice and other digestive juices further break down the food for the final absorption and extraction of essential nutrients. The food which left undigested or needs to be passed out is called waste products. This waste food passes into the large intestine for excretion through the anus.

This whole process of digestion takes place in all human beings and all the organs work in a sequence. Any problems during this digestive process can cause nausea after eating.
Therefore, the timing of nausea after eating is very important to find out the underlying pathology. During any problem in the digestive system, the body reacts by forcibly emptying the stomach through vomiting. If nausea is associated with the vomiting then the color of vomiting helps a lot in finding the problem.
