Ornithine transcarbamylase (OTC) deficiency
What can trigger hyperammonemic episodes in people with Ornithine Transcarbamylase Deficiency?
Anything that places increased stress on the body of someone with ornithine transcarbamylase deficiency can trigger an hyperammonemic episode. Viral infections are probably the most common cause, but episodes can be triggered by physical or emotional stress, dehydration, trauma, broken bones, the menstrual cycle, certain medications (like Valproic acid), pregnancy and delivery, and changes in the diet.
