Gastritis

Digestive Health & Nutrition Care
Written By Jennifer Tang

Overview

Gastritis is inflammation of the stomach lining, the protective barrier that helps shield the stomach from acid and digestive enzymes. It can develop suddenly or persist over time and may cause upper abdominal pain, burning, nausea, bloating, early fullness, or changes in appetite. Some people with gastritis have few or no noticeable symptoms.¹˒²˒³

At Tangible Health, we take an individualized approach to gastritis care by looking at your symptoms, diet, medications, lifestyle, and possible underlying contributors. Care focuses on reducing irritation, supporting comfortable digestion, addressing modifiable factors, and working alongside appropriate medical treatment when causes such as H. pylori infection are identified.

What Is Gastritis?

Gastritis refers to inflammation of the stomach lining. It can be acute, developing suddenly and lasting for a shorter period, or chronic, developing gradually and persisting over time.³˒⁴ Different types of gastritis can have different causes. Common contributors include Helicobacter pylori (H. pylori) infection, regular use of non-steroidal anti-inflammatory drugs (NSAIDs), heavy alcohol use, autoimmune gastritis, and severe physical stress associated with serious illness or injury.²˒³˒⁴

Gastritis is not the same as a stomach ulcer. Gastritis describes inflammation of the stomach lining, while an ulcer is an open sore that develops in the stomach or upper small intestine. Treatment depends on the underlying cause, which is why persistent or recurrent symptoms may require further assessment.¹˒⁴

Common Symptoms of Gastritis

Gastritis symptoms can range from mild to more significant, and some people may not experience symptoms at all.⁴ Common symptoms may include:

  • Upper abdominal pain, burning, or discomfort

  • Nausea

  • Vomiting

  • Bloating

  • Feeling full quickly when eating

  • Feeling overly full after meals

  • Reduced appetite

  • Indigestion or belching¹˒²˒³

Symptoms can overlap with other upper digestive conditions such as reflux, peptic ulcers, and functional dyspepsia, so symptoms alone cannot always confirm gastritis.⁵ Signs of gastrointestinal bleeding, such as vomiting blood, vomit that looks like coffee grounds, or black and tarry stools, require prompt medical attention.³˒⁴

Causes & Contributing Factors

Gastritis can develop for several reasons. Identifying the underlying cause helps guide the most appropriate treatment.

H. pylori Infection
H. pylori is one of the most important causes of chronic gastritis. The bacterium can live in the stomach lining and lead to ongoing inflammation, peptic ulcers, and other complications if it is not appropriately treated.⁴ Testing may involve a urea breath test, stool test, or testing performed during an upper endoscopy.⁶

Medications & Stomach Irritation
Regular use of NSAIDs, such as ibuprofen, naproxen, or aspirin, can irritate or damage the stomach lining. Alcohol can also contribute to irritation, particularly with heavier or frequent use.¹˒² Medication use should be reviewed with a healthcare provider rather than discontinued without medical guidance.

Autoimmune Gastritis
Autoimmune gastritis occurs when the immune system attacks cells in the stomach lining. Over time, this can affect the absorption of nutrients such as iron and vitamin B12 and may require ongoing medical monitoring.²˒⁴

Severe Physical Stress
Severe physical stress from major surgery, significant injury, burns, serious infection, or critical illness can contribute to acute gastritis.²˒³ Everyday emotional stress is not generally considered a direct cause of gastritis, although stress can worsen digestive symptoms and influence how strongly discomfort is experienced.⁷

Diet & Individual Triggers
Diet is not considered a primary cause of most gastritis.⁴ However, certain foods and drinks may aggravate symptoms for some people. Individual triggers may include alcohol, caffeine, spicy foods, acidic foods, large meals, or other foods that consistently worsen discomfort.¹˒⁷

Our Approach to Gastritis

At Tangible Health, gastritis care focuses on understanding what may be contributing to your stomach irritation and symptoms, while supporting digestion and working alongside appropriate medical treatment.

Your Symptoms & Digestive Health
We look at the type, timing, and severity of your symptoms, including pain or burning, bloating, nausea, appetite changes, and early fullness. We also review previous digestive diagnoses and consider whether symptoms could overlap with conditions such as reflux, ulcers, or functional dyspepsia.

Your Triggers & Contributing Factors
We review factors that may be relevant to your symptoms, including diet, alcohol, NSAID use, medications and supplements, smoking, previous H. pylori infection, stress, and other medical conditions. Rather than using the same restrictive “gastritis diet” for everyone, we focus on identifying your individual aggravating factors while maintaining adequate nutrition.

Supporting Your Stomach & Overall Health
Depending on your presentation, care may focus on reducing irritation, supporting comfortable digestion, addressing nutritional concerns, improving eating patterns, and supporting stress and lifestyle factors that may influence symptoms. If H. pylori or another medical cause is identified, naturopathic care is used alongside appropriate conventional treatment, not instead of it.

Your Goals
Your goals may include reducing pain or burning, feeling more comfortable after meals, improving appetite, identifying foods or medications that aggravate symptoms, supporting digestion during treatment, or reducing the likelihood of recurring symptoms.

Treatments That May Be Included

Your individualized care plan may include:

  • Clinical Nutrition to identify personal food triggers, support adequate nutrition, and develop eating strategies that are comfortable for your digestive system

  • Lifestyle Medicine to support eating habits, alcohol reduction, smoking cessation, sleep, and other modifiable factors

  • Botanical Medicine using selected digestive or soothing botanicals when clinically appropriate and compatible with medications and your diagnosis

  • Nutraceuticals & Supplements when there is an individualized nutritional or clinical indication

  • Naturopathic Counselling to support stress management, behavioural changes, and sustainable digestive-health habits

  • Medication & Supplement Review to identify products that may irritate the stomach or interact with treatment

  • Collaborative Care with your family doctor, gastroenterologist, pharmacist, or other healthcare providers when appropriate

When H. pylori infection is confirmed, established treatment uses a combination of medications to eradicate the infection. Botanical or nutritional therapies should not replace appropriate eradication treatment.⁸

What to Expect

Initial Assessment
We start with a detailed review of your digestive symptoms, when they occur, foods or habits that may aggravate them, medications and supplements, NSAID use, alcohol intake, stress, previous digestive conditions, and any history of H. pylori infection.¹˒⁴

Identifying Contributing Factors
From there, we look for factors that may be contributing to ongoing stomach irritation or discomfort. Depending on your symptoms, this may include reviewing dietary triggers, medications, lifestyle habits, or discussing whether testing for H. pylori or another digestive condition is appropriate.¹˒⁵˒⁶ H. pylori testing may include a urea breath test or stool test, while further medical investigation such as upper endoscopy may be recommended in certain situations.⁵˒⁶

Personalized Plan
Your care plan is developed around the likely cause of your symptoms, test results, medications, diet, lifestyle, and overall health. Recommendations may include clinical nutrition, lifestyle strategies, appropriate supplementation or botanical support, and coordination with medical treatment.

Ongoing Support
As your symptoms improve, your plan can be adjusted to reduce unnecessary dietary restrictions, support comfortable digestion, and help manage factors that may contribute to recurring symptoms. If H. pylori has been treated, follow-up testing is recommended to confirm that the infection has been successfully eradicated.⁸

Frequently Asked Questions

  • Common causes include H. pylori infection, regular NSAID use, heavy alcohol exposure, and autoimmune gastritis. Severe illness or physical trauma can also cause acute stomach-lining inflammation.²˒⁴

  • Gastritis can cause upper abdominal pain or burning, nausea, bloating, indigestion, or feeling full quickly. Some people have gastritis without noticeable symptoms.¹˒³

  • Some acute cases may improve when the irritant or trigger is removed, but persistent or chronic gastritis may require treatment of the underlying cause.¹

  • Everyday emotional stress is not usually a direct cause of gastritis, although it can make digestive symptoms feel worse. “Stress gastritis” generally refers to stomach injury associated with severe physical illness or trauma.²˒⁷

  • There is no single gastritis diet. Alcohol, caffeine, spicy foods, acidic foods, or other foods may worsen symptoms for some people, so dietary changes should focus on your individual triggers rather than unnecessary restriction.¹˒⁴

  • Yes. Confirmed H. pylori infection requires medical eradication treatment using a combination of medications, followed by testing to make sure the infection is gone.⁸

  • Naturopathic care can support nutrition, lifestyle, symptom management, appropriate supplementation, and identification of aggravating factors alongside appropriate medical testing and treatment.
