What are the symptoms of Acute Hepatic Porphyria

Signs and symptoms of Acute Hepatic Porphyria may include:

  • Abdominal pain
  • Nausea, vomiting, constipation or diarrhea
  • Numbness, tingling, or burning sensation in the feet or hands
  • Muscle weakness
  • Elevated heart rate and blood pressure

How is it diagnosed

Diagnosis can be difficult because the most common symptoms, such as unexplained abdominal pain, neuropathy, and psychological changes, are not specific to porphyria. If your doctor suspects that you have AHP, he or she will want to review your medical and family history, perform a physical exam and perform one or more diagnostic tests. When AHP is suspected, a urine porphobilinogen test should be obtained to confirm the diagnosis. Once a diagnosis is made, a porphyrin test, either urine or plasma, can be used to determine what type of AHP you have.
