Understanding Pain in the Upper Left Abdomen: Spleen Pain vs. Gastritis

Pain in the upper left abdomen can feel alarming. Two common causes—spleen pain and gastritis—often share similar symptoms, but understanding how they differ can help you decide when to seek medical care. Below, we explore each condition’s typical symptoms, what you might feel, and when to talk to a doctor.

What Is Spleen Pain?

The spleen is an organ located just beneath your left rib cage. It filters blood, stores white blood cells, and helps fight infection. When the spleen becomes enlarged or injured, you may experience pain.

Common Causes of Spleen Pain

• Splenic enlargement (splenomegaly)
  Often due to infections (mononucleosis, viral hepatitis), blood disorders, or liver disease.
• Trauma or injury
  A blow to the left side (sports injuries, car accidents) can bruise or rupture the spleen.
• Infections and inflammation
  Bacterial infections like endocarditis, or conditions such as malaria.
• Blood disorders
  Conditions such as sickle cell disease can damage spleen tissue.

How Spleen Pain Feels

• Location: Deep under the left ribs, sometimes spreading to the left shoulder (Kehr’s sign).
• Sensation:
  • A steady, dull ache or pressure-like feeling
  • Sharp, stabbing pain if the spleen is injured or ruptured
• Triggers:
  • Deep breathing or coughing may worsen the pain
  • Physical activity, especially twisting or lifting
• Accompanying symptoms:
  • Feeling full quickly when eating
  • Fatigue, fever, or signs of infection
  • Tenderness when pressing on the left upper abdomen

What Is Gastritis?

Gastritis is inflammation of the stomach lining. It can be acute (sudden onset) or chronic (long-term). Factors like infection, medications, and stress can irritate the stomach lining, leading to pain and discomfort.

Common Causes of Gastritis

• Helicobacter pylori (H. pylori) infection
  A common bacterial infection that inflames the stomach lining.
• Nonsteroidal anti-inflammatory drugs (NSAIDs)
  Regular use of ibuprofen or aspirin can erode the protective mucus layer.
• Excessive alcohol
  Irritates and erodes stomach lining.
• Stress
  Severe physical stress (serious illness, surgery) can trigger acute gastritis.
• Autoimmune conditions
  The body’s immune system attacks stomach cells in some people.

How Gastritis Feels

• Location: Upper central or left abdomen, just below the ribs.
• Sensation:
  • Burning, gnawing or sharp pain
  • A feeling of fullness or bloating after eating
• Triggers:
  • Eating spicy, fatty, or acidic foods
  • Heavy meals or irregular eating patterns
  • Alcohol or caffeine intake
• Accompanying symptoms:
  • Nausea or vomiting
  • Loss of appetite or weight loss
  • Belching or acid reflux

Key Differences to Notice

1. Onset and triggers

   • Spleen pain often follows trauma or is linked to infection and may come on suddenly.
   • Gastritis pain tends to relate directly to eating habits, alcohol use, or medication and may develop gradually.

2. Pain character

   • Spleen pain feels more like constant pressure or a deep ache; a rupture can cause excruciating, sharp pain.
   • Gastritis pain has a burning or gnawing quality that often eases or worsens with meals.

3. Associated signs

   • Enlarged spleen may cause early fullness, fever, or chills.
   • Gastritis usually comes with indigestion, bloating, or acid reflux.

When to Seek Medical Attention

Most mild gastritis can be managed with lifestyle changes and over-the-counter medicines. Spleen pain, especially after trauma, can be serious or life-threatening.

Seek immediate care if you experience:

• Sudden, severe pain in the upper left abdomen
• Fever above 101°F (38.3°C) with abdominal pain
• Lightheadedness, rapid heartbeat, or signs of shock (pale skin, sweating)
• Bloody or black stools, or vomiting blood
