How NSAIDs Cause Peptic Ulcer?

Peptic Ulcer

Nonsteroidal anti-inflammatory drugs (NSAIDs) can contribute to the development of peptic ulcers through several mechanisms. Peptic ulcers are open sores that form on the inner lining of the stomach, small intestine, or esophagus, and NSAIDs can increase the risk of ulcers in susceptible individuals. Here’s how NSAIDs can lead to peptic ulcers:

  • Irritation of the Stomach Lining: NSAIDs, such as aspirin, ibuprofen, and naproxen, can irritate the lining of the stomach (gastric mucosa). This irritation can lead to inflammation, known as gastritis, and can cause stomach pain and discomfort.
  • Reduced Mucus Production: The stomach lining normally produces a protective layer of mucus that helps shield it from the harsh acidic environment. NSAIDs can reduce the production of this protective mucus, making the stomach lining more vulnerable to damage by stomach acid.
  • Inhibition of Prostaglandin Production: NSAIDs work by inhibiting the production of prostaglandins, which are substances involved in inflammation and pain. However, some prostaglandins also play a protective role in the stomach lining. NSAIDs’ inhibition of these protective prostaglandins can make the stomach more susceptible to injury.
  • Blood Flow Changes: NSAIDs can affect blood flow to the stomach lining. This can lead to reduced blood flow, impairing the stomach’s ability to repair and regenerate itself, which is essential for preventing ulcer formation.
  • Weakening of the Mucosal Barrier: NSAIDs can weaken the mucosal barrier that protects the stomach lining from its own digestive juices, making it more susceptible to damage from stomach acid.
  • H. pylori Infection Interaction: NSAIDs can also interact with Helicobacter pylori (H. pylori), a bacterium that is a major contributor to peptic ulcers. While NSAIDs alone can cause ulcers, when combined with an H. pylori infection, the risk of ulcer formation is significantly increased.

It’s important to note that not everyone who takes NSAIDs will develop peptic ulcers. The risk varies depending on factors such as the type and dosage of NSAID, the duration of use, and individual susceptibility. Certain individuals, such as older adults and those with a history of ulcers, may be more prone to NSAID-related ulcers.

To reduce the risk of peptic ulcers while taking NSAIDs, healthcare providers may recommend:

  • Using the lowest effective dose of NSAIDs.
  • Taking NSAIDs with food or antacids to help protect the stomach.
  • Avoiding alcohol and smoking, which can increase the risk of ulcers.
  • Considering alternative pain management options for individuals at high risk of ulcers, such as acetaminophen.

If you have concerns about the use of NSAIDs and their potential impact on your stomach health, it’s important to discuss these concerns with your healthcare provider, who can provide guidance on safe and effective pain management.
