The best way to treat intestinal infection

Intestinal infection is one of the most common diseases of the gastrointestinal tract that causes the body to malfunction. In this article, Dr. Salam will acquaint you with the reasons and methods of treating intestinal infections.

A virus, bacterium or parasite enters the intestines and causes an infection. Intestinal infections are contagious. Fortunately, most intestinal infections go away on their own because they have no symptoms, but sometimes cause lethargy and weakness. These symptoms often occur when parasites, bacteria and viruses enter the gut. In fact, there are many different types of bacterial infections, and the symptoms of each of these infections are different, but fortunately, some measures can be taken to prevent intestinal infections.

Types of intestinal infections:

Small bowel infection

Infection in the small intestine is caused by microorganisms (bacteria, viruses, etc.) and manifests itself in the form of watery and bulky diarrhea. These types of infections do not need to be treated with antibiotics and heal on their own. In an infection of the small intestine, a large amount of body water is lost and must be replaced immediately. For this reason, a person should drink plenty of fluids after each bowel movement and use ORS solution with it.

Colon infection

High fever and diarrhea are not the most important signs of a colon infection, but it is possible that the diarrhea is bloody. Antibiotics are required to treat colon infections, and the patient’s stool must be tested to kill the germs with antibiotics. In this type of infection, unlike small bowel infection, not much water is lost.

What are the symptoms of intestinal infection?

In this disease, dehydration should be taken seriously. The most important symptoms of this disease are the following:

– nausea
Heartburn and pain in the body
– Fever
– Headache
– Vomit
Frequent diarrhea
Occasionally see blood or mucus in the stool

As mentioned, dehydration is so important in this disease that it can lead to death even in the elderly, so if you have an intestinal infection and severe diarrhea and vomiting, be sure to pay attention to the following symptoms that indicate dehydration in the body. :

– Thirst and dry mouth
– Headache, dizziness, especially after standing and in severe cases, weakness and impatience
– Urine opacity and if the lost water is not compensated, no urine or its amount is reduced
– nausea
– Muscle cramps and decreased energy
– In more severe cases of dehydration, facial fatigue and sunken eyes, rapid heartbeat, confusion are also observed.

In children, these symptoms should be checked by the parents as soon as the diarrhea starts, and if the child is younger, the dryness of the baby’s diaper should be noted and the physician should be informed immediately and they should refrain from taking the drug on their own.

What causes an intestinal infection?

Intestinal infections include infections of the large intestine and small intestine that originate from viral and bacterial infections.

Bacterial infection:

Campylobacter, Salmonella and Escherichia coli are common bacteria that cause intestinal infections. These bacteria enter the body through the consumption of contaminated food.

Viral infection

Consumption of contaminated water or food can cause viral infections of the intestines or gastrointestinal tract, and contact with infected people can spread the virus. Campylobacter, Salmonella and Escherichia coli are common bacteria that cause intestinal infections. Eating contaminated food causes these bacteria to enter the body.

Parasitic infection

Parasitic infection is caused by worms invading the body and multiplying. In fact, tapeworms and tapeworms cause intestinal parasitic infections.

Drinking unhealthy drinking water
Lack of proper hygiene

These conditions can also cause the spread of microbial agents that cause intestinal infections in the body. Lack of proper hand washing after going to the bathroom is one of the main reasons for contact with pathogens.


Intestinal infection can start as a result of pathogens entering the body and damaging the tissues of the gastrointestinal tract. In this way, the gastrointestinal tract may become inflamed or ulcerated, and this condition is accompanied by the appearance of new signs and symptoms of damage to the body.


Norovirus is the most common cause of diarrhea and vomiting in adults, and because it is most common during the winter, it is sometimes referred to as the “winter vomiting germ.” However, intestinal infections can occur at any time of the year.

Uncooked and raw food

Do not cook food at the right temperature or long enough

Improper food storage

Do not store food at the right temperature and warm environment

Food history of the past

Improper food consumption

Consumption of foods containing Campylobacter, Salmonella and Escherichia coli; Foods such as raw or undercooked meat, unpasteurized milk.

Are there any complications from having an intestinal infection?

People with autoimmune diseases, such as infants and the elderly, are more prone to intestinal bacterial infections. Chronic and acute infections can cause the following problems:

  • Meningitis
  • Malnutrition
  • Irritable Bowel Syndrome

How is an intestinal infection diagnosed?

Due to the protection of the immune system from the body, the patient is often unaware of the presence of bacterial infection in his intestines. Sometimes the symptoms are mild but go away within a few hours or days. But if the symptoms last longer than three days, you should see a doctor.

In these cases, the doctor can prescribe medication based on the symptoms that the patient describes. He also prescribes tests for her if needed. If your doctor suspects a specific infection, he or she can prevent further consequences by getting enough information.

How to treat an intestinal infection :

Having an intestinal infection can be very painful and upsetting for a person. Therefore, in this section, various methods for treating this problem and speeding up its recovery process have been examined.

A: Self-medication to improve intestinal infection

Drinking plenty of fluids is essential to prevent dehydration, so the patient should drink water in small, large sips. Juices and soups also prevent dehydration in adults due to diarrhea and vomiting.

If the patient is in a situation where he or she is more at risk for dehydration, such as being older or suffering from another serious illness, it is recommended that in addition to drinking plenty of fluids, oral reabsorption solutions be used.

Good hygiene: When you have an intestinal infection, you need to take good care of your condition so that the infection does not spread from your body to other people. For this purpose, the hands need to be washed regularly, especially before eating and after going to the bathroom. Also, all food must be carefully washed and thoroughly cooked before consumption.

Diet modification: As the body struggles to recover from the infection, it is important to reduce the level of pressure on the gastrointestinal tract as much as possible. For this purpose, patients are advised to use a fluid-based diet to ensure that their body water level is maintained and that the necessary electrolytes are provided to maintain organ coordination.

B: Medication to treat gastric infection

Antidiarrheal drugs: Antidiarrheal drugs are sometimes used to reduce diarrhea. Loperamide is an antidiarrheal drug commonly used to treat gastrointestinal infections. This drug slows the movement of substances in the intestine and also increases the absorption of water from the gastrointestinal tract.

Antiemetic: Antiemetic drugs, such as metoclopramide, are sometimes helpful in preventing or reducing vomiting. Metoclopramide, in the form of tablets or ampoules, relaxes the muscles used during vomiting and in the meantime accelerates the absorption of fluids and nutrients by the gastrointestinal tract.

Can an intestinal infection be prevented?

Preventing intestinal infections is not easy because germs and bacteria are present in the air, water, on the floor and on the walls. But the best way to prevent this type of infection is to follow good hygiene.

For this purpose, avoid drinking contaminated water, eating fruits, unwashed vegetables and do not use unpasteurized milk. Wash your hands thoroughly, wash surfaces that come in contact with raw foods, cook thoroughly, and limit the use of antibiotics. Also wash your hands before and after cooking. Wash your hands immediately after returning home.
