One of the most common causes of nausea long after the last meal is that the stomach produces hydrochloric acid as part of a long process to break down food and uses its best for energy and materials, according to a new study by the Gastroenterologist at the Cleveland Clinic in Ohio. And get rid of the rest, and therefore a person who does not eat for a long time to accumulate this acid in the stomach, causing nausea instead of feeling hungry.

Prolonged abstinence makes food less attractive, even if the person needs it. When acid spreads in the esophagus, it can cause acid reflux, heartburn and nausea.

Another possible group of nausea, when it comes to hunger with the body's signaling network, is to know when to eat.

These signals are regulated by the endocrine system, the glands system (including the pituitary, thyroid and pancreas), which uses the bloodstream for chemical communication.

Hormones from the endocrine system give the body the information it needs to keep its chemical levels balanced. But this balance can be disturbed if a person ignores signs of hunger or not eating regularly.

The study said that two key factors, ghrelin and leptin, play a key role in these disorders, as ghrelin is supposed to cause hunger (an important peptide for many key processes in the body, including intestinal motility, gastric acid secretion and taste and glucose metabolism). Leptin has the opposite effect, controlling ghrelin by reducing appetite.

When the body is in a normal state, these hormones are automatically regulated. '' During eating, the body releases leptin, which indicates that a person is satisfied and does not need to go hungry for a while, and when the body needs food, the ghrelin produces what makes a person hungry. However, when ignoring the signs of hunger and not eating regularly, the chemical balance between ghrelin and leptin is disturbed, so the body will produce more ghrelin to convince the person to eat, and when the level of this hormone increases, the appetite is supposed to increase, in most people, but some Who have higher sensitivity to pyramid levels Intention, the variation in hormone and other factors lead to the injury of some mild nausea when they are hungry too.
