What is the esophagus?
Ezophagus is a part of the digestive system that leads from the mouth to the stomach. Sometimes it is called a drain, it is a muscular pass that begins in the neck or pharynx. It is located between the trachea and the spine, passes down the membrane and ends at the lower esophagus of the sphincter, the muscle ring opening to the upper end of the stomach. When a person eats or drinks and vlaš, the lighting in the upper part of the esophagus, which is usually closed, opens and allows the material to go through. The muscles in the walls of the passage then pulled down and pushed them down; This process is facilitated by mucus produced by the glands along the esophagus to be moist. It then passes through the lower sphincter, which is also released and opens and enters the stomach.
Sometimes the lower esophageal sphincter opens occasionally differently than when the food is swallowed, and allows acid from the stomach to spray into the esophagus. This is known as acid reflux and usually causes heartburn, a burning feeling in the lower chest, which is unpleasant but not dangerous. When acid reflux becomes chronic, it is calledGastroesophageal reflux disease or gerd. GERD is a relatively common disorder and should be treated as the esophagus can cause damage over time. Treatment usually includes medicines such as antacides, H2 blockers and proton pump inhibitors.
People with Gerd can develop a state called Barrett's esophagus. In these cases, cells in the lower esophagus change and are replaced by cells such as cells in the stomach and intestines. These cells tolerate acid from the stomach, helping them to withstand reflux damage. Although it can reduce the discomfort of the heartburn, the condition for concerns, because Barrett cells can sometimes lead to cancer -known form known as adenocarcinoma.
In addition to adenocarcinoma, the main type of esophageal cancer is carcinoma of squamous cells. This type of cancer is often associated with the use of tobacco or alcohol, even if it can have other causes. Both cancer types usually cause pain and swallowing problems, which may lead to weight loss in patients. LeafCBA may include endoscopic therapy to remove localized lesions or laser therapy and chemotherapy for destruction of tumor cells.
