Causes of anemia caused by gastric cancer

What is the specific reason for anemia in patients with gastric cancer? Many patients with gastric cancer are basically unaware of their anemia. In fact, anemia caused by gastric cancer is mostly caused by the inability to eat normally for a long time, which leads to nausea and vomiting in the stomach. So what exactly causes anemia in gastric cancer?

Different people with gastric cancer have different constitutions, and gastric cancer patients with different constitutions will have different symptoms and conditions during the illness, such as different degrees of anemia. The main manifestations of anemia are pale conjunctiva, pale nail bed, pale complexion, fatigue, loss of appetite, palpitations, etc. These patients may have obvious blood loss symptoms, such as vomiting blood, black stools, etc., or they may have long-term chronic gastrointestinal bleeding with no obvious clinical manifestations.

The main reason for anemia in gastric cancer patients is that the local cancer foci of gastric cancer grow rapidly and lack blood supply, causing ischemia, necrosis and shedding of local cancer tissue, and the blood vessels supplying it will rupture and bleed accordingly. If the blood vessels are thicker, heavy bleeding such as vomiting blood and black stools will occur; if the blood vessels are thinner and the duration is longer, long-term chronic blood loss will occur. Excessive blood loss exceeds the body's ability to regenerate, and anemia will occur. The degree of anemia varies from mild to severe, and the degree of anemia is not closely related to the severity of the disease.

The above is the main cause of anemia in gastric cancer. I hope it can attract the attention of patients with gastric cancer. Only by caring enough about your body can you have the confidence to overcome the torture of the disease. Only by living in peace and safety can you respect life.
