Jennifer Esposito is calling her psychiatric hospitalization “excruciating” — and the word fits. The Blue Bloods actress and celiac advocate was sent to a psych ward because her doctors mistook the symptoms of undiagnosed celiac disease for a panic disorder. In a new account reported by Yahoo, she is adding detail to a story that matters far beyond her own case.
Her experience is not unusual. That is the part worth understanding.
What This Means for You
Celiac disease has more than 200 documented symptoms, and many of them have nothing to do with digestion. Anxiety, panic attacks, depression, and brain fog are all recognized manifestations of untreated celiac — but they are also the hallmarks of anxiety and psychiatric disorders. When a physician sees those symptoms, celiac disease is rarely the first thing they consider.
The result is a long and damaging wait. The average celiac patient in the United States spends six to ten years without a correct diagnosis. During that window, gluten continues to drive the immune attack that destroys the small intestine — and, in some patients, harms the nervous system, the liver, and other organs. As detailed in our report on Esposito’s liver failure, the damage from prolonged undiagnosed celiac can reach far beyond gut symptoms.
Women shoulder a disproportionate share of that wait. Research consistently shows that women presenting with celiac symptoms are more likely to receive psychiatric labels — panic disorder, generalized anxiety, somatization — before any physician considers the gut as the source. That pattern leads to a painful loop: wrong diagnosis, ineffective treatment, worsening symptoms, and escalating psychiatric referrals. For Esposito, that loop ended with hospitalization.
This matters directly to celiac families. If someone in your household has anxiety or panic attacks that do not respond to standard care, or unexplained neurological symptoms alongside even minor digestive complaints, celiac screening deserves to be on the checklist. The initial test is a single blood draw.
Key Takeaways
- Celiac disease can produce symptoms — including panic attacks — that are indistinguishable from a psychiatric disorder on first presentation.
- The average time from first symptoms to a celiac diagnosis in the U.S. is six to ten years.
- Women with celiac are significantly more likely to be labeled with a psychiatric condition before anyone screens for celiac.
- Untreated celiac causes progressive organ damage; Esposito’s case included liver failure before she received a correct diagnosis.
- Celiac screening starts with a blood test — the tTG-IgA — that any primary care physician can order.
The Science
Want to understand how celiac disease produces symptoms that read as psychiatric? The biology is well-established, and once you see the mechanism, it is hard to dismiss. Every term below is defined — no medical background required.
How an Inflamed Gut Reaches the Brain
The human gut contains roughly 500 million nerve cells — more than the spinal cord. This internal network, called the enteric nervous system (the gut’s own independent nerve system), communicates constantly with the brain through the vagus nerve (the major nerve cable running between gut and brain). Scientists call this bidirectional channel the gut-brain axis.
In celiac disease, gluten triggers an immune response that inflames the small intestine. That inflammation sends distress signals up the gut-brain axis. The brain interprets those signals as danger — and responds with anxiety, dread, and panic. The patient’s mind is not malfunctioning. The gut is sending an alarm the brain cannot ignore.
When the Nervous System Is the Primary Target
Gluten ataxia is one of the clearest examples of celiac attacking the nervous system rather than the digestive tract. Ataxia means loss of coordination and balance — in this context, it results from immune damage to the cerebellum (the brain region that governs movement). Patients with gluten ataxia may have no gut symptoms at all, yet improve significantly on a strict gluten-free diet.
Beyond ataxia, researchers have catalogued peripheral neuropathy (nerve damage producing tingling, numbness, or pain in the hands and feet) and gluten encephalopathy (brain inflammation) in celiac patients. These are not edge cases. Research by neurologist Dr. Marios Hadjivassiliou and colleagues found that gluten sensitivity may underlie 6 to 10 percent of otherwise unexplained neurological conditions.
Why Panic Disorder Fits the Wrong Diagnosis So Well
Panic disorder and undiagnosed celiac share a striking symptom overlap: rapid heartbeat, chest tightness, shortness of breath, dizziness, and overwhelming fear. Add the nutritional deficiencies common in untreated celiac — particularly magnesium, vitamin B12, and vitamin D, all essential for neurological stability — and the presentation becomes even more convincing as a psychiatric case.
A physician who is not thinking about celiac has every reason to reach for a panic disorder diagnosis. Standard psychiatric evaluations often look normal in celiac patients. Symptoms respond partially to psychiatric medications, which can delay further investigation. Because the root cause — gluten — is never removed, ongoing inflammation continues to generate new symptoms that appear to confirm the psychiatric label.
The Systemic Gap Behind Individual Stories
Esposito’s case illustrates something structural, not just personal. The diagnostic pathway for celiac disease has historically been built around gastrointestinal symptoms: diarrhea, bloating, weight loss. Patients whose primary presentation is neurological or psychiatric fall outside that expected pattern, and standard screening questions do not catch them.
When we first covered Esposito’s psych ward experience, it was striking how recognizable her story was to the celiac community — the years of escalating symptoms, the cascade of wrong labels, the sense of being told there was nothing physically wrong. What she now describes as excruciating was not only the hospitalization itself, but the experience of having a real, measurable illness treated as an imaginary one.
That experience has a name in medical literature: diagnostic delay. And the harm it causes is cumulative. Every year of undiagnosed celiac is another year of intestinal damage, nutritional depletion, and in some patients, neurological injury that may not fully reverse on a gluten-free diet.
As a celiac parent, I follow Esposito’s advocacy because I think about my son’s future — the moments when explaining his condition to a new doctor will matter, the times when symptoms might be misread, the situations where the right question at the right moment changes everything. Celiac families often become their own best advocates by necessity, because the medical system still misses this diagnosis at an alarming rate.
Esposito had the resilience and the platform to find her way to a correct diagnosis and speak publicly about what went wrong. Not every patient does. Awareness — and a willingness to ask for a tTG-IgA blood test — can shorten that path for the next person. If someone you know has treatment-resistant psychiatric or neurological symptoms that remain unexplained, her story is worth bringing into that conversation.
