On a bright Sunday morning, I and my wife got ready to go to the market. We wanted to buy some vegetables and fruits for us. But when getting ready, we found our son, Jacob vomiting in his room. He is only thirteen, and we couldn’t imagine a reason for this. So me and Catherine, my wife decided to take him to the hospital. Luckily, the doctor who checked my son was a friend of mine. He told us that there is nothing to be scared after making sure that Jacob has taken some

Dr Hayden, my friend, explained to me everything about, why do humans puke and the mechanism of vomiting as well as the treatments which must be given to each patient depending on the cause of vomiting.

I felt it very interesting and important to learn more about vomiting and I decided to google and find more information about puking on the internet. I think that sharing it with you would be important for you.

As Hayden explained, vomiting could be defined as a forceful ejection of gastric via the mouth. Vomiting usually associates with nausea, salivation and indigestion. If you didn’t know what nausea is, it is a feeling of vomiting that may or may not proceed to vomit.

vomiting may occur due to many reasons. I have listed them below for you.

1.Due to motion sickness.

(travel sickness)

2.Due to pregnancy.



5.Food intolerance.

6.Viral and Bacterial infections.

Motion sickness

If you have gone on a long trip, you might have experienced this at least once in your life. This is very commonly seen and seen very often among children. Motion sickness actually occurs as a reason for repeating motion of a vehicle or anything like that, which disturbs the inner ear of the body.

Due to pregnancy

This occurs because of progesterone, a hormone that helps pregnancy, in the first trimester. 80 to 85 per cent of pregnant women experience nausea during pregnancy and 60 to 70 per cent of them vomit. This is not commonly seen but could be severe.

Due to alcoholism

Consuming alcohol often and heavily is not at all a good habit. Consuming an excessive amount of Alcohol causes malnourishment as the alcoholics don’t eat regularly. However, alcoholism is also a reason for vomiting.

Psychogenic vomiting

Psychogenic vomiting is insidious as there is no obvious physical reason that causes vomiting. This condition is not common and may occur due to mental problems such as upset or very emotional feelings. However, treating patients who experience psychogenic vomiting is harder as it cant be cured by treating an interior organ or an internal function of the body.

Food intolerance

Vomiting that is caused by food intolerance is most commonly seen among children. When your immune system over-reacts with a substance or substance, it is mistakenly identified as a danger and triggers a safety response.

Due to viral and bacterial infections

This condition is also named as Bacterial gastroenteritis and it occurs when bacteria causes an infection in your gut. It causes inflammation in your intestines and stomach. This is why a person experiences vomiting due to bacterial infections. Nausea, abdominal cramps as well as diarrhoea. Hayden further explained to me the mechanism of vomiting.

Mechanism of vomiting

Vomiting is also called Emesis and throwing up. So it is an involuntary forceful explosion of the contents of someone’s stomach. There is a vomiting centre in our brain, which is located in an area named Medulla Oblongata.

So the vomiting centre contains a specific type of receptors known as muscarinic receptors. When those receptors are stimulated, it triggers the vomiting reflex.

There is another receptor located very close to the vomiting centre in our brain. This is called the chemoreceptor trigger zone or in short, we call the CTZ zone. So just like its name the chemoreceptor trigger zone is getting triggered by chemicals. It has two major receptors as Dopamine 2 receptors and 5 HT receptors.

When the chemoreceptor trigger zone is stimulated, it stimulates the muscarinic receptors o the vomiting centre. When the muscarine receptors of the vomiting centre are stimulated that causes vomiting reflex.

The mechanism of vomiting looked very confusing and complicated to me when dr Hayden explained it to me first. However, it didn’t look complicated when I googled the duty of the brain in vomiting. So Dr, Hayden prescribed some medicine for my son Jacob and he recovered in a few hours.

Another important area is diarrhoea and vomiting. New parents are very much considered about the treatments they should give their babies if they puke or has diarrhoea. Below information is very important for all new parents as well as for babies.
