What Are Gastritis and Duodenitis?
Gastritis refers to inflammation of the stomach lining, while duodenitis refers to inflammation of the duodenum, the first part of the small intestine located immediately after the stomach.
These conditions often occur together because both areas are exposed to stomach acid and digestive enzymes. Inflammation may develop suddenly (acute gastritis or duodenitis) or gradually over time (chronic gastritis or duodenitis).
When left untreated, severe inflammation may increase the risk of ulcers, bleeding, and other digestive complications.
What Are the Symptoms of Gastritis and Duodenitis?
Many patients search for gastritis symptoms when experiencing persistent digestive discomfort. Symptoms can vary depending on the severity and underlying cause of the inflammation.
Common Gastritis Symptoms
- Upper abdominal pain
- Burning sensation in the stomach
- Indigestion
- Bloating
- Nausea
- Vomiting
- Excessive burping
- Loss of appetite
- Feeling full quickly after eating
Chronic Gastritis Symptoms
Patients with chronic gastritis may experience:
- Persistent indigestion
- Ongoing bloating
- Recurrent stomach discomfort
- Mild nausea
- Unexplained fatigue due to nutrient deficiencies
Symptoms of Duodenitis
Duodenitis symptoms may include:
- Pain in the upper abdomen
- Burning discomfort after meals
- Nausea
- Bloating
- Indigestion
- Symptoms similar to peptic ulcer disease
Warning Signs That Require Medical Attention
Seek prompt medical attention if you experience:
- Vomiting blood
- Black or tarry stools
- Unexplained weight loss
- Persistent vomiting
- Difficulty swallowing
- Severe abdominal pain
These symptoms may indicate ulcers, gastrointestinal bleeding, or other serious digestive conditions.
What Causes Gastritis and Duodenitis?
Several factors may contribute to inflammation of the stomach and duodenal lining.
Helicobacter pylori (H. pylori) Infection
One of the most common causes of gastritis worldwide is H. pylori infection. This bacterium can weaken the stomach's protective lining and lead to chronic inflammation.
Long-Term Use of Pain Medications
Frequent use of non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, can irritate the stomach lining and increase the risk of gastritis.
Excessive Alcohol Consumption
Alcohol may damage the stomach lining and trigger inflammation.
Other Causes
- Smoking
- Severe stress
- Autoimmune conditions
- Bile reflux
- Radiation therapy
- Certain infections
How Are Gastritis and Duodenitis Diagnosed?
Accurate diagnosis is important because gastritis symptoms can overlap with other digestive disorders, including GERD, peptic ulcer disease, functional dyspepsia, and stomach cancer.
Your gastroenterologist may recommend:
Medical History and Physical Examination
A detailed review of symptoms, medications, lifestyle factors, and medical history.
Blood Tests
To identify infection, inflammation, anaemia, or nutritional deficiencies.
H. pylori Testing
Testing may include:
- Breath test
- Stool antigen test
- Biopsy during gastroscopy
Gastroscopy
Gastroscopy allows direct examination of the oesophagus, stomach, and duodenum.
This investigation can help identify:
- Gastritis
- Duodenitis
- Ulcers
- Bleeding
- Polyps
- Early signs of stomach cancer
Unsure What Is Causing Your Symptoms?
Gastritis, duodenitis, GERD, ulcers, or H. pylori infection may cause symptoms such as bloating, indigestion, stomach pain, and nausea.
Book a consultation with Dr Benjamin Yip for a comprehensive diagnosis and treatment plan.
How Are Gastritis and Duodenitis Treated?
Treatment depends on the underlying cause and severity of inflammation.
Proton Pump Inhibitors (PPIs)
These medications reduce stomach acid production and allow the stomach lining to heal.
H. pylori Eradication Therapy
If H. pylori infection is present, a course of antibiotics and acid-suppressing medication may be prescribed.
Lifestyle and Dietary Modifications
Patients are often advised to:
- Avoid alcohol
- Stop smoking
- Reduce spicy foods
- Limit caffeine intake
- Avoid unnecessary NSAID use
Ongoing Specialist Care
Patients with recurrent symptoms may benefit from continued monitoring and management by a gastroenterologist.
What Complications Can Occur if Gastritis or Duodenitis Is Left Untreated?
Untreated gastritis and duodenitis may lead to:
- Peptic ulcers
- Gastrointestinal bleeding
- Iron deficiency anaemia
- Vitamin B12 deficiency
- Gastric outlet obstruction
- Increased risk of stomach cancer in certain patients
Early diagnosis and treatment can help reduce these risks.
When Should You See a Gastroenterologist?
You should consider seeing a gastroenterologist if:
- Symptoms persist for more than two weeks
- Symptoms recur frequently
- Over-the-counter treatments are ineffective
- You experience weight loss
- You notice blood in vomit or stools
- Symptoms interfere with daily life
Persistent gastritis symptoms should not be ignored, especially if they continue despite dietary or lifestyle changes.
