Peptic Ulcer Disease: What You Need to Know
- Peptic ulcer disease predominately affects the older population, especially those between 55 and 65 years of age.
- If you contracted the bacterium Helicobacter pylori (H. pylori), you may develop peptic ulcers.
- Your doctor will use a number of diagnostic procedures to test for peptic ulcer disease, including X-rays and endoscopies. Other specialized procedures may be used if necessary.
- Treatments for peptic ulcer disease include medication and surgery.
Duodenal ulcers are more common in men, while gastric ulcers are more common in women. Stomach acids contribute to the formation of ulcers. However, many ulcers develop because of a H. pylori infection or as a result of medications.
