Anatomy of the Right Abdomen

The “right side of the stomach” spans several regions. Each region contains different organs and tissues that can trigger pain:

1. Right Upper Quadrant (RUQ)

   • Liver (right lobe)
   • Gallbladder and bile ducts
   • Portion of the right kidney (upper pole)
   • Part of the small intestine (duodenum)
   • Hepatic flexure of the colon

2. Right Flank (Mid-Abdomen)

   • Ascending colon
   • Right kidney (mid pole)
   • Right ureter
   • Abdominal muscles and nerves

3. Right Lower Quadrant (RLQ)

   • Appendix
   • Cecum (start of the large intestine)
   • Right ovary and fallopian tube (in females)
   • Right spermatic cord (in males)
   • Small intestine loops

Pain can also arise from structures in front (abdominal wall, skin) or behind (spine, ribs).

Common Causes of Pain in Right Side of Stomach

Below are some of the most frequent reasons for right-sided abdominal pain. Note that symptoms often overlap, so pinpointing the cause usually involves looking at what makes the pain better or worse, its timing, and any associated signs.

1. Gallbladder and Biliary Tract Issues

• Gallstones (Cholelithiasis):
  Sudden, intense RUQ pain or “biliary colic,” often after fatty meals. May radiate to the right shoulder.
• Cholecystitis:
  Persistent RUQ pain, fever, nausea, possibly a positive Murphy’s sign (tenderness on deep breath when pressing under the right rib).

2. Liver Conditions

• Hepatitis or Liver Swelling:
  Dull ache in RUQ, fatigue, mild fever, possible jaundice (yellowing of skin/eyes).
• Liver Abscess:
  Severe pain, high fever, chills.

3. Kidney and Urinary Tract

• Kidney Stones (Nephrolithiasis):
  Flank pain that can radiate toward the groin, blood in urine, nausea and vomiting.
• Pyelonephritis (Kidney Infection):
  Severe flank pain, fever, chills, burning with urination.

4. Appendix and Bowel

• Appendicitis:
  Starts near the belly button, shifts to RLQ, worsens with movement. Often accompanied by low-grade fever, nausea.
• Diverticulitis or Colitis:
  Inflammation of the colon can cause crampy pain, bloating, changes in bowel habits, sometimes fever.

5. Gynecologic Causes (in Women)

• Ovarian Cysts or Torsion:
  Sudden, sharp RLQ pain, sometimes with nausea or vomiting.
• Ectopic Pregnancy:
  Intense RLQ pain, vaginal bleeding—a medical emergency.

6. Musculoskeletal Strain

• Overexertion, lifting heavy objects, or sudden twisting can strain abdominal muscles, causing localized pain that worsens with movement.

7. Gas, Bloating, and Functional Disorders

• Gas Trapped in the Colon:
  Sharp, intermittent pain that may move around, often relieved by passing gas.
• Irritable Bowel Syndrome (IBS):
  Crampy abdominal pain, bloating, relief with bowel movements.

When to Seek Immediate Care

While many causes of right-sided stomach pain are mild or self-limited, some signs should prompt you to seek urgent medical attention:

• Severe, sudden pain that doesn’t improve
• High fever (over 101°F / 38.3°C)
• Persistent vomiting or inability to keep liquids down
• Blood in stool or vomit
• Difficulty breathing or chest pain
• Yellowing of the skin or eyes (jaundice)
• Signs of shock: rapid heartbeat, low blood pressure, confusion

How Is the Cause Determined?

A healthcare provider will typically:

1. Take a thorough medical history: onset, duration, type of pain, triggers, and associated symptoms.
2. Perform a physical exam, checking for tenderness, rebound pain, or signs like Murphy’s sign.
3. Order laboratory tests:
   • Complete blood count (CBC)
   • Liver function tests (LFTs)
   • Urinalysis
4. Use imaging if needed:
   • Ultrasound (good for gallbladder, liver, kidney)
   • CT scan (detailed view of abdomen and pelvis)
   • X-ray (sometimes for bowel obstruction)
