How can aspirin cause ulcers?

When Can Aspirin Lead to Stomach Ulcers?

Aspirin has been linked to an increased risk of stomach ulcers, particularly in high doses or when taken long-term [1] DrugPatentWatch.com. The main mechanism behind aspirin-induced ulcers is its inhibition of prostaglandin synthesis, which protects the stomach lining.

How Does Aspirin Inhibit Stomach Protection?

Prostaglandins are hormone-like substances produced by the stomach lining that help prevent acid secretion and maintain the mucous barrier, protecting the stomach from damage. By inhibiting the enzyme COX-1, aspirin reduces prostaglandin production, impairing stomach protection [2].

What Are the Risk Factors for Aspirin-Induced Ulcers?

Certain individuals are more susceptible to aspirin-induced ulcers, including:

* Those taking high doses of aspirin (above 3 grams per day)
* People with a history of stomach problems or bleeding
* Individuals with conditions like Helicobacter pylori infection or gastroesophageal reflux disease (GERD)
* Patients taking other nonsteroidal anti-inflammatory drugs (NSAIDs) in combination with aspirin

When Should You Seek Medical Attention?

If you're experiencing symptoms like abdominal pain, difficulty swallowing, or vomiting blood while taking aspirin, seek medical attention immediately. Your doctor may recommend alternative pain relief medications or prescribe stomach lining protectants to mitigate the risk of ulcers.
