Basic Information

Today I will be informing you guys about the digestive system and its disorders. So, the digestive system is made up of the following:

  • Oral Cavity
  • Pharynx
  • Esophagus
  • Stomach
  • Small Intestine
  • Large Intestine
  • Rectum
  • Anus
  • Salivary Glands
  • Liver
  • Pancreas
  • Gallbladder

Some digestive diseases and conditions are acute, lasting only a short time, while others are chronic, or long-lasting. Our digestive system is very important to our body. Our health and wellness is dependant on this very system as much as it is on the others. If you are to get a digestive disorder it puts your health at stake as one big part of your body is not correctly functioning and has a problem of any sort. Which is preventing it from performing its primary function.

Most Common Disorders

Stomach Ulcers

  • A stomach ulcer is when there is a break in the tissue lining of the stomach.
  • The Helicobacter pylori bacterium is known to be responsible for stomach ulcers. It causes loss of the mucous layer in our stomach. Which makes it easier for stomach acids to damage the stomach walls and our stomach muscles, like the rugae.
  • The most common symptoms are weight loss, nausea, burning sensation in the stomach and heartburn.
  • To treat stomach ulcers, patients are often prescribed antibiotics or antacids.


  • The appendix is a small, finger-shaped pouch that hangs from your colon on the lower right side of your abdomen. Appendicitis is the inflammation of that very small, finger-shaped pouch.
  • Bacteria usually invade the wall of the appendix, causing it to get infected. Which in bad cases can sometimes lead to a ruptured appendix or a pocket of pus forming in the abdomen.
  • The most common symptoms include sharp pains in the lower right abdomen, pain that worsens when sudden movements are made, nausea and loss of appetite.
  • The only treatment for this disorder is an appendectomy, which is the removal of the appendix.


  • Cirrhosis is the chronic inflammation and scarring of the liver caused by excessive alcohol intake, viruses, and genetic disorders.
  • The most common symptoms include weakness, loss of appetite, easy bruising, yellowing of the skin, itching, and fatigue.
  • The treatments for the disorder are taking steroids, having a liver transplant or a change in diet.


Diarrhea is the virus/bacterial infection when the colon fails to absorb all the water. This results in watery stool and dehydration due to the lack of water not being absorbed</li><li>The treatment is simply just to drink as many fluids as possible and eat nutritious food.

Gastroesophageal Reflux Disease (GERD)

  • Gastroesophageal reflux is the return of the stomach's acid coming back up into the esophagus. Stomach acids return into esophagus through the cardiac sphincter.
  • Gastroesophageal reflux often occurs when the lower esophageal sphincter (LES) is weak or is relaxed improperly, allowing the stomach's contents to rise into the esophagus.
  • The severity of the acid depends on what type and how much of fluid returns up from the stomach.
  • The only symptoms that occur, is a burning sensation in the esophagus and damage of the esophageal lining.
  • The treatment for this disorder is either surgery to strengthen the cardiac sphincter or antacids to neutralize the hydrochloric acid.

In the Real World

Alright, so as you all know a few months ago I believe we had an E Coli outbreak in our very own romaine lettuce. Global News Canada had released an article in which they explained more on the topic and how to recognize the symptoms.

For any of you that may not know, E Coli is a bacterium that infects and invades your intestines, which are part of out digestive system. It is associated with food poisoning, but you can also get pneumonia and urinary tract infections from different types of the bacteria.

Symptoms of E. coli infection include nausea, vomiting, headache, fever, severe stomach cramps and watery or bloody stool.

Most people will recover in a few days, but some may develop life-threatening illnesses that can cause death.

So according to this article, only a few people were affected and have gotten better. Furthermore, an article published just recently claims that the lettuce is now E Coli free and ready to eat. But we still must be cautious as bacteria is not also fully gone.


In brief, the digestive system is a very sensitive and important system of our body. So, we must do all that we can to protect it, so it performs its primary functions for our bodies. Therefore, stay healthy and avoid getting such problems.
