What Illnesses Could Cause Upper Stomach Pain and Nausea?

Common Causes of Upper Stomach Pain and Nausea

Several conditions can lead to upper abdominal pain and nausea:

• Gastritis: This is the inflammation of the stomach lining, which can cause pain in the upper abdomen, nausea, and sometimes vomiting. It can be triggered by factors such as excessive alcohol consumption, certain medications (like NSAIDs), or infections.
• Peptic Ulcers: These are sores that develop on the lining of the stomach or the first part of the small intestine (duodenum). Symptoms often include burning pain in the upper abdomen, nausea, and bloating. Ulcers can be caused by infection with Helicobacter pylori or the long-term use of certain medications.
• Gallbladder Disease: Conditions such as gallstones or cholecystitis (inflammation of the gallbladder) can cause pain in the upper right abdomen, which may radiate to the back or shoulder. Nausea is also a common symptom, especially after eating fatty foods.
• Pancreatitis: Inflammation of the pancreas can lead to severe upper abdominal pain that may radiate to the back, along with nausea and vomiting. This condition can be caused by gallstones, chronic and excessive alcohol use, or certain medications.
• Gastroesophageal Reflux Disease (GERD): GERD can cause upper abdominal pain, heartburn, and nausea due to the backflow of stomach acid into the esophagus. This condition is often exacerbated by certain foods, obesity, and smoking.

Other Potential Causes

In addition to the common causes mentioned, other conditions that may lead to upper stomach pain and nausea include:

• Infections: Viral or bacterial infections affecting the gastrointestinal tract can cause nausea and abdominal pain.
• Functional Dyspepsia: This is a chronic condition characterized by discomfort or pain in the upper abdomen without any identifiable cause.
• Cardiac Issues: In some cases, heart-related issues, such as angina or a heart attack, can present with upper abdominal pain and nausea, particularly in women.

When to Seek Medical Attention

If you experience persistent or severe upper stomach pain and nausea, especially if accompanied by other concerning symptoms (such as fever, vomiting blood, or significant changes in appetite), it is important to seek medical attention. A healthcare provider can perform a thorough evaluation, including a physical examination and possibly imaging studies or lab tests, to determine the underlying cause and recommend appropriate treatment.
