Information for Patients

Eosinophilic Disorders

Also called: Eosinophilia

Eosinophils are a type of white blood cell. They help fight off infections and play a role in your body's immune response. They can also build up and cause inflammation.

Normally your blood doesn't have a large number of eosinophils. Your body may produce more of them in response to

  • Allergic disorders
  • Skin conditions
  • Parasitic and fungal infections
  • Autoimmune diseases
  • Some cancers
  • Bone marrow disorders

In some conditions, the eosinophils can move outside the bloodstream and build up in organs and tissues. Treatment of the problem depends on the cause.

  • Eosinophil count - absolute
  • Eosinophilic fasciitis
  • Simple pulmonary eosinophilia

Esophagus Disorders

The esophagus is the tube that carries food, liquids and saliva from your mouth to the stomach. You may not be aware of your esophagus until you swallow something too large, too hot or too cold. You may also become aware of it when something is wrong.

The most common problem with the esophagus is gastroesophageal reflux disease (GERD). It happens when a band of muscle at the end of your esophagus does not close properly. This allows stomach contents to leak back, or reflux, into the esophagus and irritate it. Over time, GERD can cause damage to the esophagus. Other problems include heartburn and cancer.

Treatment depends on the problem. Some get better with over-the-counter medicines or changes in diet. Others may need prescription medicines or surgery.

  • Achalasia
  • Barrett esophagus
  • Bleeding esophageal varices
  • Diet and eating after esophagectomy
  • EGD discharge
  • Esophageal atresia
  • Esophageal manometry
  • Esophageal perforation
  • Esophageal spasm
  • Esophageal stricture - benign
  • Esophagitis
  • Esophagitis - infectious
  • Lower esophageal ring (Schatzki)
  • Mallory-Weiss tear
  • Swallowing problems
  • Tracheoesophageal fistula and esophageal atresia repair
