Although the words "ulcer" and "lesion" are often used interchangeably, the definition of "lesion" is broader, explains Dr. Douma. All ulcers are lesions, but not all lesions are ulcers.

Stomach ulcers, also called gastric ulcers, are round sores in the stomach lining produced when stomach acid eats away part of the protective mucus layer that insulates the inside of the stomach. This can result from the stomach under-producing mucus, the stomach over-producing stomach acid or both, notes Dr. Douma.

Medication management is the preferred treatment for ulcers, but surgery is sometimes necessary, states WebMD. Doctors typically recommend surgery when the ulcers do not respond to medical management or when dangerous symptoms, such as bleeding, are present.

Certain medications, such as non-steroidal anti-inflammatory drugs, are associated with ulcers, reports WebMD. Ulcers can also be caused by bacterial infections. The bacteria H. pylori is one common culprit, and it is usually treated with triple therapy, which is a combination of antibiotics, such as amoxicillin and clarithromycin, along with a proton pump inhibitor, such as omeprazole or esomeprazole.
