Retching (also known as dry heaving) is a non-productive attempt to vomit. It's a natural reflex that can occur independently or as a part of vomiting. Retching can be caused by a variety of conditions, including gastroenteritis, pregnancy, and migraines. It can also be a symptom of certain medical conditions, such as gastroparesis and bulimia nervosa.

Causes[edit | edit source]

Retching can be caused by a variety of conditions, including:

  • Gastroenteritis: This is an inflammation of the stomach and intestines, usually resulting from a bacterial or viral infection.
  • Pregnancy: Retching is a common symptom of early pregnancy, often referred to as morning sickness.
  • Migraines: Some people may experience retching as a symptom of migraines.
  • Gastroparesis: This is a condition where the stomach cannot empty itself of food in a normal fashion. It can cause nausea and retching.
  • Bulimia nervosa: This is an eating disorder characterized by binge eating followed by purging, which can include retching.

Treatment[edit | edit source]

Treatment for retching depends on the underlying cause. It may include medications to control nausea and vomiting, such as ondansetron or promethazine. In some cases, treatment may involve addressing the underlying cause of the retching, such as managing migraines or treating gastroenteritis.
