Living with a Gluten Allergy

Convincing the Skeptics

In terms of evolution, no one was designed to eat gluten. “It’s only in the last 10,000 years, when our ancestors changed their lifestyle from nomadic to settlers who domesticated crops, that gluten came into the picture,” Fasano says. “We don’t have the right enzymes to process it.” But some people don’t seem to be as bothered by the undigested protein.

When friends learn that I’m gluten-intolerant, their first reaction is to remark on how many wonderful foods I must have to forgo. Actually, the sacrifices aren’t that great. I can no longer eat pizza on white or wheat bread, traditional breakfast muffins, many ice creams and candy, and some salad dressings. Dining out requires research, and travel can be challenging, but many Washington restaurants offer special menus, and supermarkets are stocking gluten-free snacks and meals, such as pizza made with a rice-flour crust and pretzels made of gluten-free grains. There’s even a limited selection of gluten-free beers, baked goods, and ice creams that do a good job of satisfying cravings.

Sales of gluten-free foods and beverages in the United States reached $2.6 billion last year. Only 12 percent of those on a gluten-free diet have medical reasons. Others see it as a way to detox, drop pounds, or increase sports performance.

The toughest part for me was figuring out the problem. Because one of my first symptoms was a rash on my buttocks and scalp, my physician, Christine Turner, at the time with Georgetown University Hospital, urged me to see a dermatologist while she ran tests for mononucleosis, Lyme disease, thyroid problems, and a range of other possible culprits.

By the time I met with the dermatologist, the rash had faded and I’d heard the nurse in Dr. Turner’s office relay stories about her own experiences with gluten, so the question about a possible intolerance had been planted. I’d reacted the way most people do: by combing medical Web sites. During my appointment, I brought out a list of gluten-related symptoms, many of which matched mine. Both my dermatologist and her nurse practitioner waved the papers away.

My experience wasn’t unusual. Until recently, gluten sensitivity and celiac disease haven’t been on the radar of most physicians, nor have the topics been given much attention by most medical schools. Of the two, gluten sensitivity has more skeptics.

“If you came to our clinic two years ago and said, ‘Doc, I have these symptoms, and I know that when I eat less gluten I feel better,’ we’d give you a celiac test,” Fasano says. “If it came back negative, we’d tell you to go in peace. If you didn’t eat gluten and thought you felt better, we’d figure it was a placebo effect. That had been our attitude for quite a long time.”

Attitudes are beginning to change, in part due to the BMC Medicine study, which compared blood samples and intestinal biopsies from three groups: 42 subjects with confirmed celiac disease, 26 with suspected gluten sensitivity, and 39 people who served as controls. Those with gluten sensitivity didn’t display the flattened villi or leaky-gut characteristic of celiac, and while their immune systems were triggered, the reactions were less aggressive.

Some experts, such as dietitian Cynthia Kupper, hope the study will emphasize the need for more research on gluten sensitivity, celiac disease, and gluten in general. Kupper—executive director of the Gluten Intolerance Group, a national support organization—maintains that there is concern that gluten may complicate symptoms for some with multiple sclerosis, autism, or schizophrenia: “I think what we’re going to find in the next few years is that this is much bigger than we ever thought.”

Getting Help

I met with Dr. Turner, my physician, after my dermatology appointment. With the exception of low iron levels, all my tests had come back negative. But my symptoms hadn’t subsided. So Turner ordered more tests on my iron levels and reviewed my diet to make sure I was eating enough iron-rich foods. By our next meeting, my iron levels had improved slightly and I was feeling better, almost normal. I told Turner about my gluten research, about my conversation with her nurse, and that for the previous two weeks I’d been avoiding gluten.

Initially, my new diet required a lot of effort. From celiac Web sites, I got lists of troublesome foods and learned to watch for medications and vitamins containing gluten. Then I made my own list and took it to the supermarket so I could consult it while reading labels. I relied on chains such as Whole Foods, which labels most gluten-free products with a green shelf tag. Within a week, I noticed some symptoms had lifted. Within two, I felt like my old self—no more itching, no more headaches, no more fatigue or muscle aches, no more over-the-top anxiety. It felt as though I’d stumbled on a magic bullet.

Turner seemed pleased for me and not at all stunned. She said that more of her patients were insisting gluten was causing problems and that she believed them. Still, she wanted me to undergo a celiac test.

There are no tests for gluten sensitivity, though Fasano’s team is working to identify a biological marker. Meanwhile, people who suspect they have gluten sensitivity are encouraged to undergo celiac testing to rule out that diagnosis. Celiac can be diagnosed with a blood test and an upper gastrointestinal endoscopy in which tissue samples are taken from the small intestine.

I agreed to a blood test but first had to reintroduce gluten into my diet, prompting more symptoms. After ten painful gluten-consuming days, my blood was drawn. The results came back negative, but Turner supported my decision to live gluten-free, saying that the elimination diet seemed to confirm an intolerance. I was relieved and unsure at the same time. I wondered whether I had consumed enough gluten for the test to be accurate. I wondered how I’d explain what seemed like a non-diagnosis to friends and family.

Good Days and Bad Days

Like many who undergo lifestyle-altering diagnoses, I’ve tested mine in the hopes that it might turn out to be only a temporary condition. The last time was about a year and a half ago while in the process of moving. For three weeks, I felt too preoccupied to pay attention to whether my food contained gluten. Bad idea. The major symptom this time was irritability, although I initially associated that with the stress of moving. I also experienced stomach discomfort and dizziness that more than once had me crouching against a wall with my head between my knees.

I eventually consulted a psychiatrist about the irritability, thinking I might need medication. When this doctor learned of my gluten sensitivity, she urged me to eliminate gluten immediately, explaining that in people with an intolerance, eating the protein can cause neurological damage. I replied that gluten couldn’t possibly cause so much tension. On the way home, I indulged in a chocolate biscotti, silently cursing this practitioner with each gluten-laden bite. Then during a moment of clarity, I realized that my combativeness was, well, strange. I resumed gluten-free eating.

Two weeks later, I was myself. Again. I haven’t tested things since. I don’t want to. Life without gluten is a small price to pay for good health and serenity.
