The most common causes of peptic ulcer disease (PUD) are Helicobacter pylori infection and use of nonsteroidal anti-inflammatory drugs (NSAIDs). H. Pylori infection may also reduce somatostatin content and increase gastric secretion by causing hypergastrinemia leading to increase in histamine secretion and finally increased secretion of acid or pepsin form parietal cells.
