What Is Gastritis?
Gastritis refers to inflammation or irritation of the stomach’s inner lining. It can occur suddenly (acute gastritis) or develop gradually over time (chronic gastritis). This inflammation weakens the stomach’s protective barrier, allowing acid and digestive enzymes to irritate the tissue beneath. While conventional care often focuses on suppressing acid, functional medicine recognizes that gastritis is frequently a sign of deeper imbalance—triggered by infection, nutrient deficiencies, chronic stress, or impaired gut defense mechanisms.
Common Symptoms of Gastritis
Main Symptoms
- Upper abdominal pain or burning sensation, often worsened by eating
- Nausea or vomiting, sometimes with undigested food
- Bloating or early fullness after small meals
- Loss of appetite or unintended weight changes
Other Common Symptoms
- Belching, indigestion, or sour taste in the mouth
- Fatigue or weakness due to poor nutrient absorption (especially iron and B12)
- Reflux-like discomfort that persists despite acid-suppressing medications
Less Common but Related Symptoms
- Chronic gastritis can lead to systemic effects such as low energy, mood changes, or brittle nails and hair, resulting from nutrient deficiencies caused by poor stomach function. Because the stomach plays a key role in digestion and immune defense, inflammation here can also set the stage for downstream gut issues such as dysbiosis or small intestinal bacterial overgrowth (SIBO).
What Causes Gastritis?
Gastritis can result from several root factors that compromise the stomach’s natural defenses. Common causes include:
- Infection with Helicobacter pylori – a bacteria that disrupts the stomach’s protective mucus layer
- Long-term use of NSAIDs (ibuprofen, aspirin) or alcohol
- Chronic stress or trauma affecting vagal nerve function
- Nutrient deficiencies, especially B12, zinc, and antioxidants
- Autoimmune reactions against stomach cells
- Low stomach acid (hypochlorhydria), which allows harmful bacteria to proliferate
Suppressing acid may reduce short-term pain but can further impair digestion and increase infection risk. True healing comes from identifying why the stomach lining became inflamed and addressing the underlying causes.
