The Claim
Daily administration of 100 mg enteric-coated aspirin to healthy adults aged 70 years and older significantly increases the risk of major hemorrhage, with upper gastrointestinal and intracranial bleeding being the predominant drivers, mediated by the drug's antithrombotic mechanism.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Taking a daily 100 mg aspirin pill raises the chance of serious bleeding in people over 70, especially in the stomach and brain. This happens because aspirin thins the blood to prevent clots, but in older adults, that thinning effect makes them much more likely to bleed in these specific areas.
See the scientific wording
Among healthy adults aged 70 years and older taking daily 100 mg enteric-coated aspirin, the increased risk of major hemorrhage is predominantly driven by upper gastrointestinal bleeding and intracranial bleeding. The hazard ratio for upper gastrointestinal bleeding was 1.87 (95% CI 1.32 to 2.66), and for intracranial bleeding it was 1.50 (95% CI 1.11 to 2.02), indicating that aspirin's antithrombotic mechanism disproportionately elevates bleeding risks in these specific anatomical sites in the elderly population.
What the research says
1 studyStudy: Effect of Aspirin on Cardiovascular Events and Bleeding in the Healthy Elderly
Post-hoc subgroup analysis within the RCT isolates specific bleeding sites. The statistically significant hazard ratios for GI and intracranial bleeding confirm that aspirin's pharmacological action increases bleeding susceptibility at these locations.
