The main symptoms of gastrointestinal bleeding in the elderly are vomiting blood, black or bloody stools, etc. In severe cases, dizziness, panic attacks and even shock due to reduced blood volume can be life-threatening. Gastrointestinal bleeding requires different treatments depending on the cause. Among them, peptic ulcer and rupture of esophagogastric fundus varices are common causes of upper gastrointestinal bleeding, which can be treated with proton pump inhibitors and growth inhibitors. 1. Peptic ulcer: Proton pump inhibitors are preferred to inhibit the secretion of gastric acid and increase the pH value in the stomach. So that the loss of pepsin activity, stabilize the thrombus, in order to play the role of hemostasis. Commonly used proton pump inhibitors are omeprazole, lansoprazole, pantoprazole and so on. 2. Rupture of esophagogastric fundus varices: preferred vasoconstrictor drugs such as growth inhibitors, reduce portal pressure, reduce visceral blood flow, and at the same time inhibit the secretion of gastric acid, pepsin activity, in order to play the role of hemostasis. For large amounts of gastrointestinal bleeding, in addition to drug hemostasis, you can also choose endoscopic hemostasis, surgical treatment and so on. If circulating blood volume is insufficient due to excessive blood loss, blood volume needs to be replenished, and balanced fluids or glucose saline can be transfused to maintain tissue perfusion, and blood can be transfused if necessary. If the elderly have symptoms of gastrointestinal bleeding such as vomiting blood, black stools, bloody stools, etc., they should immediately go to regular hospitals and be actively treated under the guidance of professional doctors, avoiding self-diagnosis and treatment and delaying their condition.
