Introduction

In general, whether a gastroscopy is required for gastrointestinal bleeding depends on the severity of the condition, the need for determining the cause, and other specific circumstances. If you experience any discomfort, it is recommended to seek medical attention promptly. Before deciding to undergo a gastroscopy, you should truthfully inform your doctor about your medical history and medication use, especially whether you have any drug allergies or underlying medical conditions. If your condition is stable and a gastroscopy is required,

Generally, whether a gastrointestinal hemorrhage requires a gastroscopy depends on the severity of the condition and the need to determine its cause. If discomfort occurs, prompt medical attention is recommended. A detailed explanation is as follows:

If the patient's gastrointestinal bleeding condition is stable, the bleeding volume is low, there are no contraindications such as shock or severe cardiopulmonary dysfunction, and identifying the bleeding site and cause is necessary, it is recommended to undergo gastroscopy promptly. Gastroscopy allows direct visualization of the gastric mucosa, precise localization of the bleeding site, and can simultaneously perform hemostatic treatment during the procedure, helping to rapidly control the condition and provide a basis for subsequent treatment.

If the gastrointestinal bleeding is critical, such as massive hematemesis or passage of blood in stool accompanied by signs of shock, or if the patient has severe cardiopulmonary diseases or coagulation disorders, gastroscopy may not be suitable temporarily. In such cases, initial treatment should focus on stabilizing vital signs through blood transfusions and fluid resuscitation. Once the condition is controlled and the patient's general status meets the criteria for examination, the need for gastroscopy can be reassessed, thus avoiding risks during the procedure.

Prior to deciding on a gastroscopy, the patient should truthfully inform the physician about their medical history and current medications, especially any drug allergies or underlying diseases. If the condition is stable and a gastroscopy is required, the patient must fast and abstain from fluids as instructed before the procedure to ensure the gastrointestinal tract is empty. If discomfort such as worsening abdominal pain or increased hematemesis occurs after the examination, the physician should be notified promptly. Regardless of whether gastroscopy is performed, patients should cooperate with their physician to complete other necessary examinations and receive standardized treatment after identifying the cause of bleeding. Self-adjustment of treatment plans should be avoided.

What causes a bitter taste in the mouth?

Bitter taste in the mouth may be caused by factors such as imbalance of the oral environment, emotional and neurological regulation, gastrointestinal motility disorders, abnormal liver and gallbladder metabolism, or medication effects. It is recommended to maintain a daily water intake of more than 1500 ml, consume moderate amounts of hawthorn and dried tangerine peel to aid digestion, and avoid smoking and limit alcohol consumption. If bitter taste persists for over a week or is accompanied by abdominal pain, jaundice, or significant weight loss, you should visit a gastroenterology or dental clinic for further evaluation, including gastroscopy.
