Seven common types of ulcers exist, categorized primarily by their location and underlying cause. These include:
-
Peptic Ulcers: These sores develop in the lining of the stomach or the upper part of the small intestine (duodenum). They're often caused by Helicobacter pylori bacteria or long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs). Two subtypes exist: gastric ulcers (in the stomach) and duodenal ulcers (in the duodenum). [Source: Penn Medicine, Mount Sinai]

Mouth Ulcers (Aphthous Ulcers): Also known as canker sores, these painful sores appear inside the mouth. [Source: Verywell Health, Oak Street Health]

Arterial Ulcers: These ulcers result from reduced blood flow to the legs and feet, often due to peripheral artery disease (PAD). They typically appear on the toes, ankles, or lower legs and are often characterized by a lack of healing and pain. [Source: Verywell Health, Wound Evolution]

Diabetic Foot Ulcers: These ulcers occur on the feet of people with diabetes, frequently caused by nerve damage (neuropathy) and poor circulation. [Source: Oak Street Health, Verywell Health]
-
Venous Ulcers (Stasis Ulcers): These leg ulcers develop due to poor blood flow from the legs back to the heart. They typically appear on the lower legs and ankles, often accompanied by swelling and discoloration. [Source: Verywell Health, Oak Street Health]
-
Genital Ulcers: These sores form on the genitals and can be caused by various sexually transmitted infections (STIs), such as syphilis or herpes. [Source: Verywell Health, Oak Street Health]
It's crucial to consult a healthcare professional for diagnosis and treatment of any ulcer. The type of ulcer and its cause determine the appropriate treatment plan.
