This study aims to investigate whether atmospheric pressure has an effect on upper gastrointestinal bleeding (UGIB), which includes causes such as peptic ulcer disease, esophagitis, gastritis, gastrointestinal varices, Mallory-Weiss tears, and gastric cancer. The goal is to determine the impact of atmospheric pressure and gather information on its role in high-risk UGIB.

ur study aims to investigate the potential effects of changes in atmospheric pressure on gastrointestinal bleeding, and if such effects exist, to review treatment adjustments based on weather forecasts for hypertensive patients to prevent potential hypertensive emergencies and enhance patient comfort. This research poses no risk to patients and is purely observational and clinical in nature.

After initial evaluation upon presentation to the emergency department, patients will undergo routine emergency department monitoring for gastrointestinal bleeding, including physical examination, vital sign monitoring, evaluation of coagulation parameters, and hemoglobin levels. Apart from routine tests, no additional invasive or non-invasive procedures will be performed by us.

Obtained data from patients and atmospheric pressure data will be analyzed and evaluated. Results will be analyzed to determine any relation between gastrointestinal bleeding and atmospheric pressure changes
