A few months later, the woman’s apartment was broken into. Since her parents were the only ones with the key, she mistakenly believed they were to blame. After threatening them, she was admitted to a mental hospital. Worried that she was suffering from schizophrenia, docs prescribed anti-psychotics. But they didn’t stop the delusions.

So, straight out of an episode of House, M.D., docs dug deeper. They ordered tests, which showed she had several nutrient deficiencies and thyroid disease. Interviews with the family revealed she had unintentionally lost about 20 pounds, too. After a slew of tests, they began to suspect—and ultimately diagnose—the unlikely cause of her breakdown: celiac disease.

A gluten-free diet dramatically improved her symptoms. But since then, whenever she’s accidentally consumed the protein (it can hides in foods like tomato sauce and salad dressings), the delusions come back.

The takeaway: If you suspect something you’re eating is messing with your health, get to your doctor, stat.
