Overview
Abdominal pain refers to any discomfort felt between the chest and the pelvis in the abdomen. It ranges from mild, short-lived cramping to severe, disabling pain. The term covers many different problems because multiple organs and tissues lie in the abdominal area, including the stomach, intestines, liver, pancreas, spleen and reproductive organs.
Common causes and examples
Causes vary from benign to life-threatening. Common non‑emergency reasons include:
- food poisoning or gastroenteritis
- indigestion and acid-related discomfort
- constipation causing cramp and bloating
- gastritis, inflammation of the stomach lining
- peptic ulcer disease
- hunger-related or functional abdominal pain such as irritable bowel syndrome
- hunger pains or temporary discomfort from skipping meals
- and conditions that often require prompt care such as appendicitis, diverticulitis or stomach cancer.
Symptoms and clinical patterns
Healthcare providers use the pain's quality (sharp, dull, crampy), location (central, lower right, diffuse), timing (sudden versus gradual), and associated features (fever, vomiting, diarrhea, constipation, blood in stool, weight loss) to narrow the cause. Acute, localized, and worsening pain is more likely to indicate a surgical problem while chronic or recurrent diffuse pain may reflect functional disorders.
Diagnosis and treatment
Evaluation begins with a medical history and physical exam. Providers may order blood tests, urine analysis, imaging (ultrasound or CT), or endoscopy depending on suspected causes. Treatment targets the underlying diagnosis: infections get fluids and sometimes antibiotics, obstructive or surgical conditions may require procedures, and functional problems are managed with diet, medications and symptom-directed care.
When to seek urgent care
- Sudden, severe abdominal pain
- Pain with fever, persistent vomiting or inability to pass stool or gas
- Signs of internal bleeding (vomiting blood, black stools) or fainting
- Progressive swelling of the belly or signs of shock
Most episodes improve with simple measures (rest, hydration, over‑the‑counter pain relief), but persistent, severe, or worsening pain should be assessed by a clinician. For additional patient-oriented resources and guidance, consult trusted health information sources or speak with a healthcare professional. More on abdominal anatomy and specific conditions can help explain why the same symptom has many different causes.
