What is a Bacterial Infection in the Stomach?

Understanding the Culprits

When we talk about bacterial infections in the stomach, we’re usually referring to an invasion of unwanted bacteria into your gastrointestinal tract. These microorganisms, when they misbehave, can disrupt the harmony of your stomach’s ecosystem.

Helicobacter Pylori: The Usual Suspect

One of the most notorious culprits behind stomach infections is Helicobacter pylori. These spiral-shaped bacteria can penetrate the stomach’s protective lining and wreak havoc, leading to conditions like gastritis and peptic ulcers.

Common symptoms of Bacterial stomach Infections

Bacterial stomach infections can cause a range of symptoms, and these symptoms may vary depending on the specific type of bacteria involved.

Abdominal Pain:

This is a hallmark symptom. Bacterial infections can lead to crampy, sharp, or dull abdominal pain. The severity and location of the pain may vary.


Watery or loose stools are a common symptom of bacterial stomach infections. The stool may be bloody in some cases, depending on the bacteria responsible.

Nausea and Vomiting:

Many people with bacterial stomach infections experience nausea and may vomit as a result.


A fever is a common response to infection. It can be a low-grade fever or a higher fever depending on the severity of the infection.


Diarrhea and vomiting can lead to dehydration. Signs of dehydration include dry mouth, decreased urination, and increased thirst.

Bloating and Gas:

Some infections can cause excessive gas and bloating.

Weight Loss:

If the infection is prolonged or severe, it can lead to weight loss.

Blood in Stool:

In some cases, bacterial infections can lead to bloody stools, a condition known as dysentery. This is more common with certain bacteria like Shigella.

What causes a bacterial infection in your stomach?

Bacterial infections in the stomach are typically caused by the ingestion of harmful bacteria. These bacteria can enter the digestive system through contaminated food, water, or contact with infected individuals. Common causes of bacterial stomach infections include:

Contaminated Food and Water

Consuming food or water that has been contaminated with pathogenic bacteria is one of the primary causes. Bacteria like Salmonella, E. coli, and Campylobacter can be present in undercooked or improperly handled food, especially meat, poultry, eggs, and unpasteurized dairy products.

Poor Food Handling Practices:

Improper food handling, such as not washing hands, cutting boards, or utensils, can lead to the transfer of harmful bacteria to the food you eat. Cross-contamination is a common source of infection.

Consumption of Raw or Undercooked Seafood:

Raw or undercooked seafood, like oysters, can harbor Vibrio and other bacteria that can cause stomach infections.

Close Contact with Infected Individuals:

Some bacterial stomach infections, like those caused by Helicobacter pylori (H. pylori), can be transmitted through close contact with infected individuals, often within families.

Types of bacteria associated with Stomach infections include:

There are various types of bacteria that can potentially infect the stomach, causing gastrointestinal issues. Some of the common types of bacteria associated with stomach infections include:

Clostridium difficile (C. difficile):

C. difficile is a bacterium that can cause colitis, which is inflammation of the colon. This infection is often associated with the use of antibiotics, as they disrupt the balance of bacteria in the intestines.


Vibrio bacteria, such as Vibrio cholerae and Vibrio parahaemolyticus, are associated with infections caused by consuming raw or undercooked seafood, particularly shellfish.


Shigella bacteria can lead to a condition known as shigellosis, which causes diarrhea, fever, and abdominal cramps. It is highly contagious and typically transmitted through person-to-person contact.


Yersinia enterocolitica and Yersinia pseudotuberculosis are bacteria that can cause yersiniosis, leading to symptoms like diarrhea, abdominal pain, and fever. These bacteria are often found in contaminated food and water.


Diagnosing a bacterial stomach infection typically involves a combination of medical history, physical examination, and laboratory tests. Here are the steps involved in diagnosing such an infection:

Medical History:

Your healthcare provider will begin by asking you about your symptoms, their onset, and their severity. Be prepared to provide details about your recent travel, dietary habits, and any possible exposure to contaminated food, water, or infect individuals. This information helps narrow down potential causes.

Physical Examination:

The doctor may perform a physical examination to assess your overall health and look for signs of dehydration or abdominal tenderness, which are common in bacterial stomach infections.

Stool Sample:

A common diagnostic test for bacterial stomach infections involves providing a stool sample. This sample can be analyze in a laboratory to identify the presence of pathogenic bacteria or their toxins. This test is especially important when diarrhea is a prominent symptom.

Blood Tests:

Blood tests may be order to check for signs of infection and inflammation. Elevate white blood cell counts and specific markers in the blood can be indicative of a bacterial infection.


In some cases, an endoscopy may be perform. This involves inserting a thin, flexible tube with a camera (endoscope) into your stomach and upper small intestine to visually inspect the lining and collect tissue samples for analysis. This is commonly used in cases where Helicobacter pylori (H. pylori) infection or peptic ulcers are suspect.


In rare cases, imaging studies such as X-rays, CT scans, or ultrasound may be use to look for signs of complications or structural abnormalities in the digestive tract.

Common Bacterial infections that can affect the stomach:

Helicobacter pylori (H. pylori) Infection:

This is one of the most common bacterial infections of the stomach. H. pylori is a bacterium that can cause gastritis (inflammation of the stomach lining) and peptic ulcers. It is usually treat with a combination of antibiotics and acid-suppressing medications.

Salmonella Infection:

Salmonella is a type of bacteria that can cause food poisoning. Ingesting contaminated food or water can lead to symptoms such as diarrhea, abdominal cramps, fever, and vomiting.

Campylobacter Infection:

Campylobacter is another type of bacteria that can cause gastroenteritis, leading to symptoms like diarrhea, abdominal pain, and fever.

Clostridium difficile (C. difficile) Infection:

C. difficile is a bacterium that can cause colitis, an inflammation of the colon. This infection is often associated with the use of antibiotics. Symptoms include diarrhea, fever, and abdominal pain.

E. coli Infection:

Certain strains of E. coli can lead to gastroenteritis. Symptoms may include diarrhea, abdominal cramps, and vomiting. In severe cases, it can cause hemolytic uremic syndrome (HUS), a potentially life-threatening condition.

How to Treat

The treatment for a stomach bacterial infection typically involves the use of antibiotics to target and eliminate the harmful bacteria responsible for the infection. However, the specific treatment may vary depending on the type of bacteria causing the infection, its severity, and individual factors. Here is a general outline of the treatment process:

Identification of the Bacteria:

The first step is to identify the specific bacterium responsible for the infection through diagnostic tests, such as stool samples or endoscopy.

Complete the Course:

It’s essential to take the prescribed antibiotics exactly as instruct by your healthcare provider, even if your symptoms improve before the course is complete. This helps ensure that all the bacteria are eradicated, reducing the risk of recurrence and antibiotic resistance.

Supportive Care

In addition to antibiotics, supportive care is often necessary to manage symptoms and promote recovery. This may include over-the-counter medications to relieve abdominal pain or nausea and maintaining proper hydration. In cases of severe dehydration, intravenous (IV) fluids may be administer.

Diet Modification

Your healthcare provider may recommend dietary modifications to ease your symptoms. This can include a bland diet, avoiding spicy or greasy foods, and consuming clear fluids to stay hydrated.
