Hi, Abdominal pain, nausea, and dizziness can have several potential causes, ranging from minor to more serious conditions. Here are some possibilities to consider: * Gastroenteritis: This is an infection of the stomach and intestines, often caused by a virus or bacteria. Symptoms can include stomach pain, nausea, vomiting, and diarrhea. * Gastritis: Inflammation of the stomach lining can cause burning pain in the upper abdomen, nausea, and vomiting. * Gastroesophageal reflux disease (GERD): This is a condition where stomach acid flows back into the esophagus, causing heartburn and a burning sensation in the chest or upper abdomen. * Peptic ulcer disease: Ulcers can develop in the stomach or small intestine, causing burning pain in the upper abdomen and nausea. * Appendicitis: This is a condition where the appendix becomes inflamed and can cause abdominal pain, nausea, and vomiting. * Pancreatitis: Inflammation of the pancreas can cause upper abdominal pain, nausea, and vomiting. * Food poisoning: Consuming contaminated food or drink can cause abdominal pain, nausea, vomiting, and diarrhea. * Menstrual cramps: In women, severe menstrual cramps can cause nausea and dizziness. If your symptoms persist or worsen, it is important to seek medical attention from a healthcare provider to determine the underlying cause and receive appropriate treatment. Take care.
