What Are the Causes of Dull Pain in the Right Upper Abdomen?
In daily life, many people experience persistent, dull abdominal pain. Dull pain in the right upper quadrant (RUQ) may indicate liver-related conditions, but it can also be closely associated with diseases affecting the colon, small intestine, and other adjacent structures. So, what causes dull pain in the right upper abdomen?
What Causes Dull Pain in the Right Upper Abdomen?
Dull RUQ pain has numerous potential causes. Intra-abdominal organs located in this region include the liver, gallbladder and biliary tract, head and body of the pancreas, duodenum, right kidney, right adrenal gland, right portion of the colon, and peritoneum. Inflammation, tumors, ischemia, or spasm involving any of these structures may produce RUQ pain. Moreover, extra-abdominal pathologies can also manifest as RUQ pain.
Common etiologies include: liver disorders, such as fatty liver disease, hepatic abscess, or hepatocellular carcinoma—enlargement of the liver or presence of a mass stretches the Glisson’s capsule, stimulating intra-abdominal nerves and causing pain; gallbladder and biliary tract disorders: the gallbladder and bile ducts lie deep beneath the liver in the RUQ; inflammation, biliary stones, or ascariasis may cause RUQ pain that often radiates to the right shoulder; diseases of the hepatic flexure of the colon: the ascending colon turns horizontally at the RUQ to become the transverse colon—the so-called “hepatic flexure”; pathology or gas accumulation here may elicit RUQ pain; other causes, including lower right lung or pleural disease, diaphragmatic involvement, angina pectoris, herpes zoster, costochondritis, or intercostal neuralgia—all of which may refer pain to the RUQ.The differential diagnosis for RUQ pain is complex; accurate diagnosis requires consideration not only of local factors but also of systemic clinical features.
