Porphyria is a group of diseases in which substances called porphyrins build up, negatively affecting the skin or nervous system. The types that affect the nervous system are also known as acute porphyria, as symptoms are rapid in onset and last a short time. The disease was described as early as 370 BC by Hippocrates.

Porphyrins are essential for the function of hemoglobin; a protein in your red blood cells that links to porphyrin, binds iron, and carries oxygen to your organs and tissues.

Complications may include paralysis, low blood sodium levels, and seizures. Attacks may be triggered by alcohol, smoking, hormonal changes, fasting, stress, or certain medications. If the skin is affected, blisters or itching may occur with sunlight exposure.
