Symptoms and signs of acute porphyrias involve the nervous system, abdomen, or both (neurovisceral). Attacks develop over hours or days and can last up to several weeks. Most gene carriers experience no, or only a few, attacks during their lifetime. Others experience recurrent symptoms.
Symptoms include weakness in the body, loss of appetite, diarrhea, loose or watery stools, stomach cramps, upset stomach, projectile vomiting (uncommon), bloating, excessive gas, and burping (often sulfurous). Symptoms typically develop 9â15 days after exposure, but may occur as early as one day.Symptoms are caused by Giardia organisms infecting the cells of the duodenum and jejunum of the small intestine and blocking nutrient absorption.
