Oksendamisega

Oksendamisega, more commonly known as vomiting or emesis, is the forceful expulsion of stomach contents through the mouth. This physiological reflex is typically triggered by the brain's vomiting center, which can be stimulated by various factors. These include irritants within the stomach, such as toxins or spoiled food, as well as signals from other parts of the body, such as motion sickness or severe pain. The process involves a coordinated effort of several muscle groups, including the diaphragm and abdominal muscles, to increase intra-abdominal pressure, which then pushes the stomach contents upward through the esophagus and out of the body.

Nausea, a feeling of unease and the urge to vomit, often precedes the act of vomiting. While vomiting can be an unpleasant experience, it serves as a protective mechanism to rid the body of potentially harmful substances. However, repeated or severe vomiting can lead to complications such as dehydration, electrolyte imbalances, and aspiration, where stomach contents enter the lungs. Medical attention is often sought for persistent vomiting, especially if accompanied by other concerning symptoms like fever, severe abdominal pain, or blood in the vomit. Treatment focuses on addressing the underlying cause and managing symptoms like dehydration through fluid replacement.
