Below the left chest is the area of the stomach and spleen. If abnormalities occur, the patient will usually experience nausea, vomiting, acid reflux, belching, hiccups, abdominal distention, abdominal pain, etc. Gastritis, gastric ulcer or stomach tumor are usually considered, and gastroscopy is recommended to clarify the condition of the stomach. The spleen is one of the largest immune organs in the body. If the spleen is thickened or enlarged, it can be seen in liver cirrhosis or hematologic disorders. In cirrhosis, symptoms such as splenomegaly, portal vein widening, splenic vein widening and hypersplenism may occur. Ultrasound or enhanced CT examination of the liver, gallbladder and spleen is recommended for a definitive diagnosis. Hematologic disorders such as leukemia can also cause spleen enlargement, and bone aspiration is recommended for a definitive diagnosis.
