What Is Vomiting

Vomiting is forcing the contents of the stomach up throughout the mouth. To remove the non-toxic or harmless substance from the body after ingestion is called emesis.

Vomiting is a violent act in which the empty stomach has to overcome the pressure that in place to keep solid food and secretion within the stomach.

The empty stomach almost reflexes itself inside out –forcing into the lower portion of the esophagus during emesis episodes.

Vomiting is a cause is food poisoning and gastritis head injury, brain cancer. Nausea and vomiting is the discomfort felt before emesis but not all worsen nausea results in emesis.

Vomiting Accomplished By

 Emesis is accomplished by a fierce, downward contraction of the diaphragm muscles.

At the same time, the abdomen muscles tighten against a relaxed stomach with an open gastro-esophageal sphincter.

The content of the stomach is propelled up and out.

Vomiting Reflex

As a part of the body reflex person may produce excessive saliva just before the emesis.

It is a complex, coordinated reflex orchestrated by the emesis center of the brain. that response to brain signals coming from;-

  • The mouth, stomach, and intestine.
  • The bloodstream, which may contain medicine or infections.
  • The balancing system in the ear (morning sickness).
  • The brain itself, including unsettling sights, smells or thought.

Definition Of What Is Vomiting

Nausea and the desire to do nothing Sometimes, the symptoms are referred to as sick. Food pipes (the esophagus) are forced to carry poop and vomit into the mouth.

Types of Vomiting 

Depending on the causes of the vomiting, there can be different types. The different types of emetics are seen in the nature of the ejected material i.e. vomitus.

The simple kind of emesis is that which occurs when a person overeats.

Vomitus contains a fragment of undigested food , bland foods that is expelled out of the digestive tract due to the overloading in the stomach and upset stomach.

Such as vomit is not harmful. In fact, it is beneficial because it frees up the overstuffed alimentary tract.

In people with the chronic problem as gastritis, gastric ulcer, esophageal or gastrovaricos and digestive tract hemorrhage the person may vomiting blood.

Such as condition is known as hematemesis. It is a dangerous condition and required medical treatment.

Few times they contain browny particles that look like a coffee bean. Actually, it’s a semi-solid particle of blood that is oxidized of iron. which has already oxidized.

That is called coffee grounds vomiting, which is a symptom of several airborne infectious diseases.

Causes Of What Is Vomiting 

Commonly emesis reflex trigger by brain signals, and this signal can be generated by smell, taste, various types of illness, and emotions like severe pain, motions, injury, fear, food irritation, infection, dizziness and etc. Specifically these

  • Eating disorder (anorexia and bulimia )
  • Certain viruses.
  • Food poisoning and food allergies.
  • Infection, viruses.
  • Motion sickness.
  • Vertigo ( the sensation that the room is spinning around ).
  • Head injuries.
  • Severe include Headache.
  • Migraine headaches.
  • Brain tumor.
  • Brain infection (meningitis ).
  • Morning sickness during pregnancy.
  • Chemotherapy in cancer patients.

Pathophysiology Of Vomiting

Vomiting is so many sources of having to vomit center:

  1. The chemoreceptor trigger is the base of the fourth ventricle has numerous dopamine D2 receptors,serotonin5-HT receptors, opioid receptors, acetylcholine receptors, and receptors for substance p.stimulation of the different receptor are involved in the different pathway leading to emesis, in the final common pathway substance appears involved.
  2. The vestibular system, which sends information to the brain via control nerve-VIII (Vestibulocochlear nerve), plays a major role in motion sickness and is rich in muscarinic receptor and histamine H1 receptors.
  3. The cranial nerve X(vagus nerve) is activated when the pharynx is irritated, leading to a gag reflex.
  4. The vagal and enteric nervous system inputs transmit information regarding the state of the gastrointestinal system irritation of the GI mucosa by chemotherapy, radiation, distention, or acute infections gastroenteritis activates the 5HT receptors of these inputs.
  5. The CNS mediates vomiting that arises from psychiatric digestive disorders and stress from higher brain centers.

The vomiting act encompasses three types of output initiated by the chemoreceptors trigger zone, motor parasympathetic nervous system, and sympathetic nervous system  the are follows

  • Increased salivation to protect tooth enamel from stomach acids .exessive emesis leads to dental erosions .this is part of PNS.
  • The body takes a deep breath to avoid aspirating vomit.
  • Retroperistalsis starts from the middle of the small intestine and sweeps up digestive tract contents into the stomach, through the relaxed pyloric sphincter.
  • Intracranial pressure lower (by inspiration against a closed glottis) coupled with an increase in abdominal pressure as the abdominal muscles contract, propels stomach contents into the esophagus as the lower esophageal sphincter relaxes.
  • The stomach itself does not contract in the process of vomiting except for at the angular notch nor is there any retroperistalsis in the esophagus.
  • It is ordinarily preceded by retching
  • Emesis also initiates an SNS response causing both sweating and increase heart rate.
  • The neurotransmitter that regular vomiting are poorly understood but inhibitors of dopamine, histamine,e, and serotonin are all used to suppress Emesis, suggesting that these play a role in the initiation or maintenance of a vomiting cycle. vasopressin and neurokinin may also participate.

Symptoms Of What Is Vomiting

  2. Involuntary expulsion of food from the mouth and nose.

The second stage is called dry heaves or reaching. There is a follow nausea and vomiting. Without any expulsion of gastric content can occurs without any vomiting but usually generating the negative pressure that leads to emesis.


The final stage is vomiting occurs when the gastric and often small intestine content is propelled up to and out of the mouth. It results from a highly coordinated serious event that could be described as the following series of steps;-

A deep breath is taken the glottis is closed and the larynx is raised to open the upper esophageal sphincter.

Also, the soft palate is elevated to close off the posterior nares. The diaphragm is contracted downward and opening of the gastric cardiac.
