Back pain stomach pain what's going on

Back pain and stomach pain are usually caused by duodenal ulcer, gastric cancer, and pancreatic diseases. Below the pylorus of the stomach is the duodenum, which is located in the first and third lumbar vertebrae. When there is a disease in the duodenal mucosa, such as duodenitis or duodenal ulcer disease, it not only causes stomach pain but also radiates to the surrounding area, so it can also cause back pain. Gastric cancer is a serious malignant tumor disease, which invades the blood vessels of the stomach wall. Gastric cancer also metastasizes to the periphery when it enters the advanced stage. once it metastasizes to the pancreatic capsule, the patient will show radioactive pain in the back. Pancreatic diseases include pancreatitis, pancreatic cyst, pancreatic cancer, etc. Because pancreas itself belongs to retroperitoneal organ, it will cause symptoms of back pain when it comes on, and pancreatic diseases will also affect stomach digestion of food, but also cause stomach pain.
