What causes epigastric pain

Overview

Epigastric pain refers to discomfort or pain felt in the upper central region of the abdomen, often described as a burning, gnawing, or sharp sensation. This area, known as the epigastrium, houses several vital organs, including the stomach, the first part of the small intestine (duodenum), the lower part of the esophagus, the pancreas, and parts of the liver and gallbladder. Therefore, pain in this region can stem from a wide array of conditions affecting these organs, ranging from minor digestive disturbances to serious medical emergencies.

Common Causes of Epigastric Pain

Digestive System Issues

The most frequent culprits behind epigastric pain are related to the digestive tract.

• Indigestion (Dyspepsia): This is a very common condition characterized by discomfort, bloating, nausea, and pain in the upper abdomen, often after eating. It can be triggered by eating too quickly, consuming fatty or spicy foods, excessive alcohol or caffeine, smoking, stress, and certain medications.
• Gastritis: This is the inflammation of the stomach lining. It can be acute (sudden onset) or chronic (long-lasting). Causes include infection with Helicobacter pylori (H. pylori) bacteria, regular use of NSAIDs (nonsteroidal anti-inflammatory drugs) like ibuprofen or aspirin, excessive alcohol consumption, and stress. Symptoms often include a burning pain, nausea, vomiting, and a feeling of fullness.
• Gastroesophageal Reflux Disease (GERD): When stomach acid frequently flows back into the esophagus, it causes GERD. This backward flow, or reflux, irritates the lining of the esophagus and can manifest as heartburn, which is often felt as a burning sensation in the epigastric area and chest. Other symptoms include regurgitation, difficulty swallowing, and a chronic cough.
• Peptic Ulcers: These are sores that develop on the lining of the stomach or the duodenum. The most common causes are H. pylori infection and long-term use of NSAIDs. The pain is typically a burning or gnawing sensation that may worsen when the stomach is empty and improve after eating or taking antacids. If untreated, ulcers can lead to serious complications like bleeding or perforation.
• Gastric and Duodenal Ulcers: Specifically, gastric ulcers are in the stomach, while duodenal ulcers are in the duodenum. Their symptoms and causes overlap significantly with general peptic ulcers.
• Irritable Bowel Syndrome (IBS): While IBS primarily affects the large intestine, some individuals experience pain in the upper abdomen, including the epigastric region, along with symptoms like bloating, gas, diarrhea, and constipation.
• Celiac Disease: An autoimmune disorder where consuming gluten leads to damage in the small intestine. Epigastric pain can be one of the symptoms, alongside diarrhea, bloating, weight loss, and fatigue.

Pancreatic Issues

The pancreas is located behind the stomach in the epigastric region, making it a common source of pain in this area.

• Pancreatitis: This is inflammation of the pancreas. It can be acute (sudden and severe) or chronic (long-lasting). Gallstones and heavy alcohol use are the leading causes. The pain is often severe, sudden, and may radiate to the back. It can be accompanied by nausea, vomiting, fever, and rapid pulse.

Gallbladder Issues

The gallbladder stores bile and is situated beneath the liver in the upper right abdomen, but its issues can cause epigastric pain.

• Gallstones (Cholelithiasis): These are hard deposits that form in the gallbladder. When gallstones block the bile ducts, they can cause sudden, intense pain in the upper right abdomen or the epigastric region, known as biliary colic. The pain may last for minutes to hours and can radiate to the shoulder or back.
• Cholecystitis: This is inflammation of the gallbladder, often caused by a gallstone blocking the cystic duct. It typically causes severe epigastric or upper right abdominal pain, fever, and tenderness.

Other Potential Causes

While less common, epigastric pain can also signal other serious conditions:

• Heart Attack (Myocardial Infarction): Especially in women, a heart attack can present with symptoms that mimic indigestion, including epigastric pain, nausea, shortness of breath, and sweating. It is crucial to seek immediate medical attention if you suspect a heart attack.
• Aortic Aneurysm: A bulge or swelling in the aorta, the main artery carrying blood from the heart. A ruptured abdominal aortic aneurysm can cause sudden, severe abdominal pain, which may be felt in the epigastric area. This is a life-threatening emergency.
• Hernia: Certain types of hernias, particularly hiatal hernias where part of the stomach pushes up through the diaphragm, can cause epigastric pain and heartburn.
• Certain Cancers: Although less common, cancers of the stomach, pancreas, or liver can present with epigastric pain, often as a later symptom.

When to Seek Medical Attention

While occasional mild epigastric pain may resolve on its own, it's important to consult a healthcare professional if you experience:

• Severe or persistent pain
• Pain accompanied by fever, nausea, vomiting (especially if bloody), or changes in bowel habits
• Difficulty swallowing
• Unexplained weight loss
• Pain radiating to the jaw, neck, arm, or back
• Shortness of breath or sweating

A healthcare provider can diagnose the cause of your epigastric pain through a physical examination, medical history, and potentially diagnostic tests such as blood work, endoscopy, ultrasound, or CT scans.
