Gastritis

What is Gastritis?

Gastritis refers to inflammation of the stomach lining. This condition can develop suddenly (acute gastritis) or progress slowly over time (chronic gastritis), with causes ranging from infections and medications to stress and dietary habits.

Acute Gastritis: Sudden Onset of Stomach Inflammation

Acute gastritis occurs when the stomach lining becomes inflamed quickly, often with sharp and noticeable symptoms. Common causes include:

Medications (such as NSAIDs like ibuprofen or aspirin)
Infections (bacterial or viral)
Psychological stress (emotional strain can impact stomach health)
Dietary triggers (high intake of fatty, spicy, or highly processed foods)
Food contamination (ingesting contaminated food or drinks)

Acute gastritis episodes are typically short-lived but can be intense, often improving with the removal of the triggering factor.

Chronic Gastritis: Long-Term Stomach Inflammation

Chronic gastritis is a persistent, ongoing inflammation of the stomach lining. Unlike acute cases, symptoms can last for months or even years. If left untreated, chronic gastritis may become a lifelong condition.

The leading cause of chronic gastritis is infection with the bacterium Helicobacter pylori (H. pylori), which damages the protective lining of the stomach over time. Other contributing factors include long-term use of irritant medications, autoimmune disorders, and prolonged stress.

Nervous Gastritis (Functional Dyspepsia): When Stress Affects the Stomach

A unique type of gastritis often referred to as “nervous gastritis”, is medically known as Functional Dyspepsia. Unlike other forms of gastritis, this condition doesn’t involve visible inflammation or damage to the stomach lining. However, it can cause similar symptoms, such as:

Stomach discomfort or pain
Bloating and fullness
Nausea

Nervous gastritis is primarily triggered by emotional stress and anxiety, which disrupt the normal movement (motility) of the stomach. Treatment typically focuses on psychological and lifestyle interventions rather than medications for inflammation.

Common Symptoms of Gastritis

Stomach pain or burning sensation
Nausea or vomiting
Bloating and a feeling of fullness
Indigestion
Loss of appetite

When to Seek Medical Attention

If you experience persistent stomach discomfort, unexplained weight loss, or signs of bleeding (such as black stools or vomiting blood), consult a healthcare provider. Proper diagnosis often involves tests for H. pylori infection, endoscopy, and lifestyle assessment.

Key Takeaway

Gastritis is a common yet diverse condition that can be acute, chronic, or functional. Identifying the underlying cause—whether bacterial, dietary, or stress-related—is essential for effective treatment and long-term relief.
