Gastritis Symptoms

Gastritis, or inflammation of the stomach lining, can cause a variety of symptoms. The severity and specific symptoms may vary depending on the underlying cause, the extent of inflammation, and individual factors. Here are some common symptoms associated with gastritis.

Abdominal pain or discomfort

This is one of the most common symptoms of gastritis. The pain may be dull, burning, or gnawing in nature. It is typically located in the upper abdomen and may worsen after eating or when the stomach is empty.

Nausea and vomiting

Gastritis can trigger feelings of nausea, which may sometimes lead to vomiting. Vomiting may provide temporary relief, but it does not resolve the underlying inflammation.

Indigestion and bloating

Gastritis can cause indigestion, characterized by a feeling of fullness or discomfort in the upper abdomen after eating. It may also contribute to bloating and excessive gas.

Loss of appetite

Many individuals with gastritis experience a decreased appetite or a feeling of early fullness during meals. This can result in unintended weight loss.

Heartburn and acid reflux

Gastritis can lead to increased acid production in the stomach, which can result in symptoms such as heartburn, a burning sensation in the chest or throat, and regurgitation of stomach acid.

Dark stools

Gastritis can cause bleeding in the stomach, which may result in the passage of black, tarry stools (melena) or blood in the vomit (hematemesis). However, not all cases of gastritis involve bleeding.


Chronic gastritis and its associated symptoms can contribute to feelings of fatigue and low energy levels.

It’s important to note that these symptoms can vary among individuals, and some individuals may experience mild symptoms or be asymptomatic. Additionally, symptoms may come and go or vary in intensity depending on factors such as diet, stress, and the underlying cause of gastritis.

If you are experiencing persistent or bothersome symptoms, it’s advisable to seek medical evaluation from a healthcare professional. They can provide an accurate diagnosis, determine the underlying cause of your gastritis, and recommend appropriate treatment options to alleviate your symptoms and promote healing.

What are the Diagnostic tests for Gastritis

To diagnose gastritis and determine its underlying cause, healthcare professionals may use various diagnostic tests. These tests can help evaluate the condition of the stomach lining, identify any infections, or detect other contributing factors. Here are some common diagnostic tests for gastritis:

Upper endoscopy (esophagogastroduodenoscopy, or EGD)

This is a procedure in which a flexible tube with a camera on the end (endoscope) is inserted through the mouth and into the esophagus, stomach, and duodenum. It allows the healthcare professional to directly visualize the lining of the stomach and obtain biopsies (small tissue samples) for further examination.


During an upper endoscopy, small tissue samples (biopsies) may be taken from the stomach lining. These samples are then sent to a laboratory for analysis to determine the presence of H. pylori infection, assess for signs of inflammation, or rule out other conditions.

Blood tests

Blood tests can help evaluate the presence of H. pylori antibodies, which can indicate an ongoing or past H. pylori infection. Blood tests can also measure certain markers of inflammation or identify specific antibodies associated with autoimmune gastritis.

Stool tests

Stool samples may be collected to check for the presence of H. pylori bacteria or signs of gastrointestinal bleeding.

Breath test

This test involves consuming a special liquid or capsule containing a substance that, if H. pylori is present, will be broken down by the bacteria and release certain gases. The gases are then measured in the breath to determine the presence of H. pylori.

Imaging tests

In some cases, imaging tests such as X-rays or abdominal ultrasound may be performed to evaluate the stomach and surrounding organs for any abnormalities or signs of gastritis.

The specific diagnostic tests recommended will depend on the individual’s symptoms, medical history, and suspected underlying cause of gastritis. It’s important to consult with a healthcare professional who can evaluate your specific situation and determine the most appropriate diagnostic approach.

Is Acid Reflux similar to Gastritis?

Acid reflux and gastritis are two distinct but related conditions that involve the digestive system. While they share some similarities, they have different causes and characteristics.

Acid reflux, also known as gastroesophageal reflux disease (GERD), occurs when stomach acid flows back up into the esophagus. This happens due to a weakened lower esophageal sphincter (LES), which is a ring of muscle that normally prevents stomach acid from refluxing into the esophagus. Acid reflux can cause symptoms such as heartburn, regurgitation of acid or food, chest pain, and difficulty swallowing.

On the other hand, gastritis refers to inflammation of the stomach lining. It can be caused by factors such as H. pylori infection, excessive alcohol consumption, long-term use of NSAIDs, certain medications, autoimmune disorders, or other irritants. Gastritis can lead to symptoms such as abdominal pain or discomfort, nausea, vomiting, indigestion, and loss of appetite.

While acid reflux and gastritis are separate conditions, they can coexist or contribute to each other. Acid reflux can irritate the stomach lining and contribute to the development of gastritis. Conversely, gastritis can lead to increased acid production and worsen acid reflux symptoms.


It’s important to note that chronic acid reflux, if left untreated, can lead to complications such as erosive esophagitis (inflammation and damage to the esophagus) or Barrett’s esophagus (changes in the lining of the esophagus that can increase the risk of esophageal cancer).

If you experience symptoms of acid reflux or gastritis, it’s advisable to seek medical evaluation from a healthcare professional. They can provide an accurate diagnosis, determine the underlying cause, and recommend appropriate treatment options to alleviate your symptoms and promote healing.
