The diagnosis of an eosinophil-associated disease depends on where the eosinophils are found in increased number:

Eosinophilic Gastrointestinal Disorders (EGID):
  > Eosinophilic Esophagitis: esophagus
  > Eosinophilic Gastritis: stomach  
  > Eosinophilic Enteritis: small intestine
  > Eosinophilic Colitis: large intestine

Eosinophilic Pneumonia: lungs

Eosinophilic Cystitis: bladder

Eosinophilic Granulomatosis with Polyangiitis, also known as Churg-Strauss Syndrome: lungs, sinuses, heart, various organ systems

Hypereosinophilic Syndrome: blood and any organ

Eosinophilic Fasciitis: connective tissue

The symptoms depend on the type of affected organs. Eosinophil-associated diseases are chronic and require long term management. Symptoms may be debilitating and often lead to missed time at school and work and may greatly impact a patients’ quality of life.
