Vomiting is eviscerate activity through the mouth caused by the action of the motor digestive tract. May facilitate the ability to throw up the poison from the stomach spending. Causes of vomiting can be due :
1). Infectious disease or inflammation in the digestive tract or in the center
balance.
2). Diseases such as metabolic disorders
disorders of carbohydrate metabolism (galactosemia, etc.), disorders
metabolism of amino acids / organic acids (such as urea cycle disorders and
phenylketonuria).
3). Disturbances in the nervous system (neurologic) may be due
interference with the structure (eg hydrocephalus), the presence of infection (meningitis and encephalitis), or because of toxicity (eg, nerve poisoning by asiodosis and other metabolic byproduct), as well as.
4). Physiological conditions such as those occurred in
children who are seeking attention from the surrounding environment with
throat with a finger probe.
Acute gastroenteritis disease
is a cause of vomiting is most common in children. In this condition, vomiting usually occurs together with diarrhea and abdominal pain. Generally caused by viruses and pathogenic bacteria. The main viral causes
vomiting is rotavirus, while bacterial pathogens include Salmonella, Shigella,
Campylobacter and Escherichia coli.
Vomiting occurred after the stimulus given to the central vomiting (vomiting
center, VC) or at the trigger zone kemoreceptor (chemoreceptor trigger zone, CTZ) located in the central nervous system (Central nervous system). Vomiting coordination centers can be activated by a variety of ways.
Vomiting occurred
due to physiological stress, takes place because of the signal transmitted through the outer layer of the brain and limbic systems to the vomiting center (VC). Puke associated with the movement occurs when the VC is stimulated through the system muscle arrangement (vestibular or vestibulocerebellar system) from the labyrinth
ear contained in the interior.
Chemical signals from the flow of blood and cerebrospinal fluid (neural network brain to the tail bone) were detected by CTZ.
Nerve endings and nerves inside the digestive tract is the trigger vomiting in case of digestive tract irritation, bloating and delayed gastric emptying process. When the vomiting center (VC) stimulated, the motor of the Cascade will react to cause vomiting.
Contraction
Non peristaltic increase in the small intestine, gallbladder contraction and
some contents from the duodenum into the hull. This condition is followed by a slowdown peristaltic movement that would encourage the entry of the contents of the small intestine and secretion pancreas into the stomach and suppressing the activity of the stomach. Meanwhile, the respiratory muscles would contract against a closed glottis, resulting in enlargement of the throat.
At the time of abdominal muscles (Abdominal) contract, the stomach contents would be pushed into the esophagus. Relaxation of the abdominal muscles allows contents of the stomach into the esophagus re-entry.
Cycles of rapid vomiting up all stomach contents entering into the esophagus removed all.
On the condition of vomiting was also an increase in saliva production,
increased respiration rate and heart rate and pupil dilation
eye.
In the case of food poisoning by S. aureus, vomiting occurs swallowing caused by staphylococcal enterotoxin formed by these bacteria. That staphylococcal ingested, it will bind to the major antigen histocompatability complex (MHC), which stimulates T cells to release cytokines. These cytokines will further neuroreseptor stimulate existing in the digestive tract and stimulation will be forwarded to the central nervous system, triggering the vomiting center (VC) and cause vomiting.
