Nausea and Vomiting
Nausea and vomiting are signs of an underlying disorder and are attributed to an infection that is not unique. [5] Nausea is a sense you can feel when the stomach needs to empty itself, while vomiting (emesis) or throwing up is the act of forcible emptying of the stomach. The word “dry heaves” refers to a vomiting episode where there is no food in the stomach and only small quantities of clear body fluids are vomited.
Vomiting is a violent act in which, in a synchronized manner, the liver, esophagus, stomach, and small intestine violently expel the contents of the stomach (and often the small intestine).
In the case of pylori gastritis, vomiting may be frequent (and sometimes in the form of acid reflux to cause heartburn). Vomiting often contains blood and can be unbearably painful.
