Overview

The symptoms of diphyllobothriasis usually develop after eating undercooked or raw infected fish meat and start with symptoms such as abdominal pain, diarrhea, nausea, vomiting, and tiredness. If left untreated, patients with diphyllobothriasis may progress to develop complications such as megaloblastic anemia, cholecystitis/cholangitis, and intestinal obstruction. Prognosis is generally good.

Natural History

Complications

The complications associated with diphyllobothriasis include:

Prognosis

  • Diphyllobothriasis can be removed with a single treatment dose. There are no lasting effects.
