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
- 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.[1][2]
- Human Diphyllobothrium infection becomes infectious (begins to pass eggs in stools) approximately 15 to 45 days after ingestion of plerocercoid larvae.[1]
- Without treatment, the patient will develop symptoms of intestinal obstruction and infections of the biliary tract.[1][2][3]
Complications
The complications associated with diphyllobothriasis include:
- Megaloblastic anemia
- Intestinal obstruction
- Cholecystitis or cholangitis(As a result of migration of proglottids)
Prognosis
- Diphyllobothriasis can be removed with a single treatment dose. There are no lasting effects.
