    What is gastroparesis?

    Gastroparesis is a condition in which the stomach empties its content much later than is normal. The food, as we swallow, moves to our stomach. Once it reaches the stomach, the stomach contracts to gradually move the food into the small intestine where it is absorbed. This movement of the food from stomach to small intestine is controlled by the vagus nerve. When the vagus nerve becomes damaged, the muscles of the stomach and the small intestine stop working normally. The result is that food is pushed very slowly out of the stomach or may even stop within the digestive tract. This condition is known as gastroparesis, or delayed gastric emptying.

    Digestion

    The stomach is comprised of three parts. The upper portion of stomach is called the pylorus and fundus. In this portion, the swallowed food and liquid accumulate. The lower portion is called the antrum and in this portion, the food is grinded into small pieces and then passed on to duodenum, which is the starting part of small intestine.

    Another important feature of the stomach is the ‘pacemaker.’ This pacemaker creates electrical waves which sweep across the stomach. As a result of each wave, the lower portion of the stomach contracts, grinds the food and then pushes small amounts of the ground food into the small intestine. Normally, this happens three times in a single minute.

    When a person is suffering from gastroparesis, the pacemaker in the upper portion of the stomach starts to malfunction. As a result, the rate of the electrical waves generated by the pacemaker slows down and the stomach contracts less often than normal. This results in a slower movement of food from the stomach to the small intestine. The food simply lies in the stomach, digested by stomach juices and slowly pulled into the intestine under the force of gravity.

    The pacemaker usually starts malfunctioning when the vagus nerve, the nerve that controls the stomach contractions, is damaged. There are a number of reasons why the vagus nerve is damaged and starts to malfunction. These are detailed in the next chapter.

    Sometimes, gastroparesis may occur even when the pacemaker is working perfectly. This happens when
