porphyrias are a family of medical conditions in which a substance called heme is not produced properly. heme consists of a compound called porphyrin joined to an iron atom and it is an essential part of hemoglobin in red blood cells. porphyrias are caused by a lack of functioning enzymes that participate in the heme-making process. the enzyme deficiency results in a buildup of the porphyrin compounds in the body which can cause tissue damage. most porphyrias are inherited. symptoms of porphyria can include: abdominal pain light sensitivity resulting in skin rashes muscle and nerve problems (pain seizures or abnormal sensations) red or brown urine porphyria is a lifelong condition. treatments vary depending on the type of porphyria and its severity. certain porphyrias can be made worse by alcohol drugs sunlight or other triggers; your doctor can advise on the best way to prevent such attacks.
