Diseases of the digestive system: What are they and how can they be prevented?

Stomach pain and gastric reflux are just a couple of the most common issues that can arise when the digestive system isn’t working properly. As a result, digestive system diseases can come in a variety of shapes and sizes, with a variety of symptoms. Most gastrointestinal diseases can be avoided if are detected early enough.


Digestive diseases are among the most common health problems worldwide, but especially in the United States. Many digestive system problems can be avoided, so it’s important to know which ones are the most common, why they occur, and how to deal with them.

According to a report, digestive pathology has increased in recent years as a result of the modern lifestyle, which is manifested in the diet by an increase in the consumption of highly processed foods, saturated fats, concentrated sugars with rapid absorption, and salt.


Digestive pathology encompasses all gastrointestinal, liver, and pancreatic diseases as a result of disorders of the digestive tract or appendages. Constipation or irritable bowel syndrome, for example, are pathologies that, while not considered serious or life-threatening, can significantly reduce one’s quality of life, as can serious pathologies such as colorectal cancer.

The digestive tract (oral cavity, esophagus, stomach, small intestine, large intestine, rectum, and anus) and appendix organs are the basic components of the digestive apparatus (salivary glands, liver, gallbladder, and pancreas). All of this works together to transport and process food so that the body can get the nutrients it needs.


Among the most common digestive symptoms are:

Nausea and/or vomiting


Abdominal discomfort

Commonly diagnosed digestive pathologies include:


Gastroesophageal reflux disease (GERD) (which is a type of gastroesophageal reflux)


The most common digestive system problems are usually easy to control or treat with a few lifestyle changes and, in some cases, medication. In other cases, gastrointestinal problems can be a sign of a more serious underlying medical condition.


What causes nausea or vomiting?

The feeling of nausea that the vast majority of people experience at some point, for various reasons, is referred to as the uncontrollable urge to evacuate the contents of the stomach. This symptom is frequently followed by vomiting. Vomiting is caused by a strong stomach contraction that pushes the contents of the stomach into the esophagus and then into the oral cavity.


The causes of nausea and vomiting range from physiological causes such as pregnancy to less serious causes (gastritis of various causes) to serious causes such as endocrinological disorders, neurological diseases, and even cancers or chemotherapy.

Indigestion, food poisoning, viral infections, chronic digestive disorders, irritable bowel syndrome, Crohn’s disease, bulimia and anorexia, intestinal obstruction, cholecystitis, Rotavirus infection, gastroesophageal reflux syndrome, hepatitis, gastroduodenal ulcer, pancreatitis, pancreatic cancer, liver cancer, administration of certain drugs, and so on are all examples of situations in which we may experience nausea with or without vomiting.

When nausea or vomiting is not caused by a medical condition, hydration is recommended half an hour after the last episode of vomiting. Moderate amounts of water or sweetened tea are recommended, and if the body tolerates them, they should be gradually increased.


If you notice signs of dehydration (thirst, dry mouth, decreased urine output, feeling weak and tired), headache, confusion, constant abdominal pain, bloating, or other symptoms, you should see a doctor. Antiemetics are commonly used to help people who are experiencing nausea.


The only way to prevent nausea and vomiting episodes is to avoid situations that are known to cause these symptoms: avoiding food excesses, avoiding excessive alcohol, being aware of situations where there is a pathology such as eating disorders (anorexia, bulimia), and keeping known endocrinological pathologies under control.


Diseases of the gastrointestinal tract. Constipation and Causes

Constipation is defined as the presence of fewer than three stools in a week, each of which has a hard consistency and must be eliminated with effort or pain (the definition is constantly being adjusted; it can fit into the term constipation practically any change in the stool from individual to individual when the stool is rarer or harder to evacuate as before).

Bloating in the abdomen may occur as a result of the treatment. Constipation usually occurs when we don’t eat enough fiber, don’t drink enough water, or when our routine is disrupted by events such as travel, lack of physical activity, or the use of certain medications.


How to deal with it:

In the case of prolonged constipation, the doctor may prescribe laxatives, which can often be obtained without a prescription. Laxatives differ in terms of how they work:

Volume laxatives absorb water and swell, stimulating secondary intestine motility and making it easier to evacuate (for example, lactulose)… Castor oil, for example, is a type of laxative that softens and lubricates the stool.

Laxatives are strong stimulants that speed up the process and irritate the intestine, which is why they should not be used for long periods of time.



Constipation can be avoided by drinking plenty of water, exercising regularly, and eating at least 20 grams of fiber each day.


Because we are often tempted to choose a laxative solely based on TV commercials or the advice of those around us, something that can only be helpful in the short term or lead to “addiction” to a certain laxative, the doctor is best advised to give advice on the most appropriate laxative.



Diarrhea is defined as three or more loose stools per day, sometimes with cramps, or simply a higher number of stools than usual. Diarrhea can be caused by a variety of factors, including infection with bacteria or viruses spread through contaminated food. Consumption of dairy products, especially in the case of lactose intolerance, as well as caffeine and artificial sweeteners, could be another factor.

Frequent stools can be caused by certain medications, such as antibiotics, and digestive disorders, such as irritable bowel syndrome.


Our method of nutrition has a direct impact on our health, physical well-being, and mental equilibrium. As a result, the digestive system’s role is far more important and complex. The gradual elimination of food debris is essential for health, and a healthy digestive system ensures the proper functioning of the entire organism.

The digestive system’s job is to help the body digest the food it eats, and bacteria in the intestines, known as intestinal or microbial flora, aid digestion. Food is broken down into nutrients that the body uses for energy, growth, and cell repair. Constipation, diarrhea, vomiting, bloating, and other symptoms are all symptoms of an imbalance in the proper functioning of this system.


Tips for dealing with and preventing certain digestive issues include:

Adopt a fiber-rich diet.

Foods with a high fat content, as well as foods with a low fat content, should be avoided.

Probiotics and prebiotics should be consumed.

Maintain a consistent meal schedule and drink plenty of water.
