Common causes of abdominal pain

Abdominal pain can result from various conditions, including:

  • Indigestion: Often caused by overeating or consuming spicy foods, leading to discomfort after meals.
  • Gastroenteritis: An inflammation of the stomach and intestines, usually due to infection, causing diarrhea, nausea, and vomiting.
  • Irritable Bowel Syndrome (IBS): A chronic condition that affects the large intestine, leading to cramping, abdominal pain, bloating, gas, and diarrhea or constipation.
  • Appendicitis: Inflammation of the appendix, which can cause severe pain in the lower right abdomen.
  • Gallstones: Hardened deposits in the gallbladder that can block the bile duct, causing sharp pain in the upper right abdomen.

Diagnostic tests for abdominal pain

To diagnose the cause of abdominal pain, healthcare providers may use several tests, including:

  • Blood tests: These can check for signs of infection or inflammation. For example, a high white blood cell count may indicate an infection.
  • Urinalysis: This test can help identify urinary tract infections or kidney stones.
  • Ultrasound: A non-invasive imaging test that uses sound waves to create images of the organs within the abdomen.
  • CT scan: A more detailed imaging test that can provide cross-sectional images of the abdomen, helping to identify issues like appendicitis or tumors.
  • Endoscopy: A procedure where a flexible tube with a camera is inserted through the mouth to view the esophagus, stomach, and small intestine.

Can stress cause abdominal pain? Yes, stress can contribute to abdominal pain, particularly in conditions like irritable bowel syndrome (IBS), where stress can exacerbate symptoms.

Is abdominal pain always a sign of a serious condition? Not always. Abdominal pain can be caused by something as simple as indigestion. However, persistent or severe pain should be evaluated by a healthcare provider.

When to see a doctor
