Celiac disease (or celiac sprue) is a problem with digesting gluten. Gluten is a type of protein found in wheat, rye, and other grains. This problem starts when the body's immune system attacks the small intestine when gluten is eaten. The immune system is supposed to fight off viruses and other invaders, but sometimes it turns on the person's own body. (This is called an autoimmune disease.) Celiac disease seems to run in families.
Celiac disease causes damage to the small intestine. This makes it hard for the body to absorb vitamins and other nutrients. You cannot prevent celiac disease. But you can stop and reverse the damage to the small intestine by eating a strict gluten-free diet.
Celiac disease is an abnormal immune system reaction to gluten, a protein found in grains like wheat, barley, rye, and triticale (a wheat-rye cross). It damages the small intestine so that it can't do a good job of absorbing nutrients from your food.
If you have celiac disease, you need to avoid foods that contain gluten.
Celiac disease is also known as celiac sprue, gluten-sensitive enteropathy, and nontropical sprue.
Celiac disease is a lifelong (chronic) condition. In adults, symptoms may occur at any age, but they are most common in the person's 20s, 30s, and 40s. In some children, symptoms start shortly after cereal is introduced into the diet, usually after 6 months of age.
Sometimes a person who has celiac disease doesn't have symptoms after eating foods that contain gluten. But damage to the small intestine is still occurring.
Within 2 weeks after starting a gluten-free diet, most people with celiac disease find that their symptoms improve. Symptoms should completely disappear within 3 months. Staying on a gluten-free diet usually keeps symptoms from coming back. It also lowers the risk for complications.
Children who have untreated celiac disease can become very ill. They may need to go to the hospital for treatment with fluids and medicine to restore nutrients.
Symptoms of celiac disease include:
Symptoms may come and go. They may be very mild and go completely unnoticed. Or they may be severe symptoms that impact your daily life.
The treatment for celiac disease is to avoid all foods that have gluten. This is called a gluten-free diet. Eating even the smallest amount of gluten can cause symptoms such as weight loss and diarrhea.
A gluten-free diet means:
Gluten can also be in things you may not expect, like medicine, vitamins, and lipstick.
You may also be advised to avoid milk or milk products for a while until your intestine heals. Then you may be able to slowly reintroduce them.
If you have nutritional deficiencies, you may need other treatments. Treatments include vitamin, iron, and calcium supplements.
Your doctor will ask questions about your symptoms and do a physical exam.
You may have blood tests to see if you have certain antibodies that could mean you have the disease. Celiac disease triggers the immune system to produce these antibodies.
To find out for sure if you have celiac disease, you will probably have an endoscopy. In this test, a doctor uses a thin, lighted tube to look at the inside of your small intestine. Your doctor can also take small samples of tissue to be tested in a lab. This is called a biopsy.
If the biopsy shows signs of celiac disease (such as abnormal villi and inflammation in the small intestine), a gluten-free diet will be recommended.
A diagnosis of celiac disease is confirmed if the diet makes symptoms go away and if antibody tests become normal.
Eating a gluten-free diet will help you avoid symptoms and damage to the small intestine. It helps to read food labels carefully and look for hidden gluten. Also look for gluten in medicine and some food additives.
Celiac disease is a problem some people have with foods that contain gluten. Gluten is a type of protein. It's found in the grains wheat, barley, rye, and triticale (a wheat-rye cross).
When you have this disease and you eat food with gluten in it, the gluten triggers an immune response that isn't normal. This damages the inside of your small intestine so that it can't do a good job of absorbing nutrients from your food.
Celiac disease can lead to anemia or osteoporosis.
In children, celiac disease can slow growth and weaken bones. If it isn't treated, your child can get very sick.
Doctors think celiac disease may be a problem with your immune system. Eating foods that contain gluten may trigger the problem. Having certain genes can increase your chance of getting it. You're more likely to have these genes and get celiac disease if a close family member has the disease.
Having celiac disease means that you will need to follow a gluten-free diet from now on. This can be hard, especially if you don't have symptoms.
These tips may help.
Dietitians, other health experts, and celiac disease support groups can give you lots of help. Try keeping a food diary until you are more familiar with planning meals without gluten.
Read labels on prepared or processed food carefully. For example, "hydrolyzed vegetable protein" may come from wheat and contain gluten.
Store gluten-free foods in a separate place from foods that contain gluten. Make sure you keep cooking surfaces, utensils, and appliances clean and free of gluten before you use them. If you use a toaster, use a separate toaster for gluten-free breads.
If you eat food you don't prepare, such as at a restaurant, make sure you let those preparing the food know that you have special dietary needs.
This helps you make sure that you're getting enough nutrients.
This helps you avoid constipation. If you need to, use gluten-free commercial fiber preparations, such as those that contain rice bran.
