Acute Hepatic Porphyria (AHP)
AHP encompasses a group of rare genetic conditions characterised by a deficiency in enzymes involved in the production of heme. This can lead to a build-up of toxic substances causing severe, potentially life-threatening attacks. AHP can cause a range of symptoms, from severe abdominal pain to neurological complications, significantly impacting quality of life. Understanding AHP is essential for early diagnosis and effective management.
