Managing coeliac disease means following a strict gluten-free diet for life, but researchers are working on new treatments that could one day offer additional options beyond diet alone.

Living with Coeliac Disease: What Treatment Can Achieve

When someone is diagnosed with coeliac disease, the main goal of treatment is to stop the ongoing damage to the small intestine and help the body heal. This means preventing the immune system from attacking the gut lining every time gluten is consumed. The treatment approach focuses on managing symptoms like diarrhea, stomach pain, bloating, and fatigue, while also preventing serious long-term complications such as malnutrition, bone weakness, and fertility problems^[1][2].

The way coeliac disease is treated depends on how severe the symptoms are, whether the person has already developed complications, and how well they can stick to dietary changes. Some people notice symptoms improving within days to weeks of changing their diet, while for others it may take months or even years for the intestine to fully heal^[10]. There is no cure yet, but medical teams work with patients to control the condition and improve their quality of life.

Today, doctors follow treatment guidelines approved by medical societies, which primarily focus on removing gluten from the diet. However, researchers around the world are studying new therapies that might one day help people with coeliac disease manage their condition in additional ways. These experimental treatments are being tested in clinical trials and could eventually change how we think about managing this lifelong condition^[12][14].

Standard Treatment: The Gluten-Free Diet

The cornerstone of coeliac disease treatment is following a gluten-free diet, which means completely avoiding all foods and products that contain wheat, barley, rye, and sometimes oats. This is not just a lifestyle choice or a preference—it is a medical necessity. Even tiny amounts of gluten can trigger damage to the small intestine, even if the person doesn’t feel any symptoms right away^[9][10].

Gluten is a protein found naturally in these grains, and it appears in many common foods like bread, pasta, cereals, cookies, cakes, and beer. It can also hide in unexpected places such as sauces, soups, packaged foods, and even some medications, vitamins, toothpaste, and lip balm^[3][10]. Learning to identify and avoid these hidden sources is an important part of treatment.

When someone with coeliac disease stops eating gluten, the inflammation in the small intestine begins to calm down. The tiny, finger-like projections called villi that line the intestine and absorb nutrients can start to heal and grow back. This process is called recovery from villous atrophy. As the intestine heals, the body becomes better at absorbing vitamins, minerals, and other nutrients from food, which helps reverse problems like anemia, weight loss, and bone thinning^[15].

For most people with coeliac disease, sticking to a gluten-free diet leads to significant improvement in symptoms. Many patients report feeling much better within weeks, with less bloating, diarrhea, and stomach pain. However, complete healing of the intestine can take much longer—sometimes up to two years or more—especially in adults^[9].

When someone is first diagnosed, they are usually referred to a registered dietitian who specializes in coeliac disease. This professional helps the person learn which foods are safe, how to read food labels, how to avoid cross-contamination (when gluten-free food accidentally comes into contact with gluten-containing food), and how to plan balanced meals that provide all the nutrients the body needs^[10][11].

Cross-contamination can happen easily. For example, using the same knife to spread peanut butter on regular bread and then on gluten-free bread can transfer enough gluten to cause problems. At home, families may need separate cutting boards, toasters, and utensils for gluten-free cooking. When eating out at restaurants, it’s important to ask about how food is prepared and whether the kitchen takes steps to prevent cross-contamination^[9][21].

In countries like the United Kingdom, some patients can receive gluten-free foods like bread and flour on prescription from their doctor, which helps reduce the financial burden of the diet^[9]. Fortunately, the availability of gluten-free products has increased dramatically in recent years, making it easier to find alternatives in supermarkets and health food shops.

Many naturally gluten-free foods can be enjoyed freely, including meat, fish, eggs, dairy products like cheese and milk, fruits, vegetables, potatoes, rice, and gluten-free flours made from rice, corn, soy, or potato^[9]. By law in many countries, foods labeled as gluten-free must contain less than 20 parts per million of gluten, which is considered safe for most people with coeliac disease^[9].

There is some debate about oats. Pure, uncontaminated oats do not contain gluten, but they do contain a protein called avenin that a small number of people with coeliac disease may react to. More commonly, oats are contaminated with wheat, barley, or rye during growing or processing. For this reason, many doctors recommend avoiding oats unless they are specifically labeled as gluten-free and the person has been monitored to make sure they tolerate them well^[9][19].

Doctors typically recommend annual check-ups for people with coeliac disease. During these visits, the healthcare provider will measure height and weight, review symptoms, discuss the diet, and check whether the patient needs any additional nutritional supplements or specialist advice^[9].

In some cases, people with coeliac disease may need additional treatments beyond diet. For example, if the spleen is not working properly due to the disease, doctors may recommend certain vaccinations to protect against infections. If someone has developed a skin condition called dermatitis herpetiformis—an itchy rash with clusters of bumps or blisters—they may need specific skin treatments in addition to the gluten-free diet^[9][19].

The gluten-free diet does not usually cause significant side effects, but it requires permanent lifestyle changes. Some people find it challenging to stick to the diet, especially in social situations, when traveling, or when dining out. Emotional and psychological support is important, and many patients benefit from connecting with support groups or working with healthcare professionals who understand these challenges^[16].

Treatment in Clinical Trials: New Approaches Under Investigation

Although the gluten-free diet is effective for most people with coeliac disease, it is not perfect. Some patients continue to have symptoms or intestinal damage even when they try their best to avoid gluten. This can happen because of accidental gluten exposure from hidden sources or cross-contamination. Others struggle with the difficulty and social limitations of the diet. For these reasons, scientists are actively researching new therapies that could help manage coeliac disease in different ways^[12][14].

These experimental treatments are being tested in clinical trials, which are carefully designed research studies that evaluate whether new therapies are safe and effective. Clinical trials have different phases. Phase I trials focus on safety and involve a small number of participants. Phase II trials test whether the treatment works and involve more people. Phase III trials compare the new treatment with the current standard treatment in large groups of patients to see if it offers real benefits^[14].

One promising area of research involves drugs that break down gluten in the digestive system before it can trigger an immune response. These are called gluten proteolysis therapies. The idea is that if gluten can be broken down into harmless fragments before it reaches the small intestine, the immune system won’t react and the intestine won’t be damaged. Researchers are developing special enzymes that can be taken as a pill or supplement with meals to help digest gluten^[14].

Another strategy being studied is preventing gluten from being absorbed in the first place. Some experimental treatments work by binding to gluten in the stomach or intestine, making it too large to pass through the intestinal wall and triggering its removal from the body before it causes harm. This approach is sometimes called “removing gluten from the digestive tract”^[14].

Researchers are also looking at ways to strengthen the intestinal barrier. In coeliac disease, the connections between the cells lining the intestine (called tight junctions) become loose, allowing gluten fragments to pass through more easily and trigger inflammation. Experimental drugs are being developed to promote the assembly and strength of these tight junctions, which could help prevent the immune reaction^[14].

Another target for new therapies is an enzyme called tissue transglutaminase 2, which plays a key role in how the immune system reacts to gluten in people with coeliac disease. By inhibiting this enzyme, researchers hope to block the inflammatory process. Drugs designed to inhibit tissue transglutaminase 2 are being tested in clinical trials^[14].

Some scientists are investigating the use of probiotics—beneficial bacteria that live in the gut—as a way to help manage coeliac disease. The idea is that changing the balance of microorganisms in the digestive system might reduce inflammation or help the intestine heal. While this approach is still in the early stages of research, some studies have shown promising results^[14].

Immunotherapy approaches are also being explored. These treatments aim to retrain the immune system so it stops attacking the body when gluten is consumed. One type of immunotherapy involves exposing the immune system to small amounts of gluten in a controlled way, with the goal of building tolerance over time. Another approach involves developing vaccines that could prevent the immune reaction to gluten. These are complex treatments that require careful testing to ensure they are safe and effective^[14].

Clinical trials for coeliac disease are being conducted in many countries, including the United States, Europe, and other regions. To participate, patients usually need to meet certain criteria, such as having a confirmed diagnosis of coeliac disease, being within a certain age range, and being willing to follow the study requirements. Some trials may recruit people who continue to have symptoms despite following a gluten-free diet, while others may look for newly diagnosed patients^[1][12].

While these new therapies are exciting, it’s important to remember that they are still experimental. The gluten-free diet remains the only proven, safe, and effective treatment for coeliac disease. Until new treatments complete all phases of clinical trials and receive approval from regulatory authorities, patients should continue to follow their doctor’s advice about diet and lifestyle management.
