GORD and PUD are two types of digestive diseases. Gastro-oesophageal reflux disease (GORD) is when stomach acid flows back up into the oesophagus (the tube that carries food from your mouth to your stomach). This causes irritation and inflammation of the oesophagus. Peptic ulcer disease (PUD) is when an ulcer forms in the stomach or small intestine. Ulcers are open sores that can cause pain, nausea, and other symptoms.
GORD is caused by a malfunction of the lower oesophageal sphincter (LES), which is a muscle that helps keep the oesophagus closed. This allows stomach acid to flow back up into the oesophagus, causing irritation and inflammation. PUD is caused by bacteria or overuse of certain medications, such as non-steroidal anti-inflammatory drugs (NSAIDs).
The main differences between GORD and PUD are the causes and symptoms. GORD is usually caused by a malfunction of the LES, whereas PUD is usually caused by bacteria or an overuse of certain medications. The symptoms of GORD include heartburn, regurgitation, and chest pain, while the symptoms of PUD include abdominal pain, indigestion, nausea, and vomiting.
In conclusion, GORD and PUD are two different types of digestive diseases with different causes and symptoms. GORD is caused by a malfunction of the LES, while PUD is usually caused by bacteria or an overuse of certain medications. GORD usually causes heartburn, regurgitation, and chest pain, while PUD usually causes abdominal pain, indigestion, nausea, and vomiting.
