About Celiac Disease
The causes of celiac disease are related to a unique genetic predisposition due to the presence of specific genes (HLA-DQ2 and/or HLA-DQ8) and the production of certain autoantibodies. This leads to the activation of immune mechanisms when gluten is consumed, resulting in damage to the small intestinal villi and malabsorption of nutrients.
Non-modifiable risk factors (factors that a person cannot change or control) for celiac disease include:
- Family history: Having a parent or sibling with celiac disease increases the risk.
- Genetic predisposition: The presence of HLA-DQ2 and/or HLA-DQ8 genes increases susceptibility.
- Sex assigned at birth: Celiac disease can affect both males and females. However, studies have shown that females are more likely to be diagnosed with the condition compared to males.
- Race or ethnicity: Although celiac disease can affect people of any race or ethnicity, it is more commonly diagnosed in individuals of European descent. However, it is important to remember that celiac disease can occur in people from all racial and ethnic backgrounds.
Modifiable risk factors (factors a person can change or control) for celiac disease are not well-established, but some potential factors that have been explored include:
- Poor dietary habits: Consuming a diet high in gluten-containing foods, such as wheat, barley, and rye, increases the risk of developing celiac disease. Gluten is the main trigger for the immune response in individuals with celiac disease. Therefore, adopting a gluten-free diet can significantly reduce the risk.
- Timing of gluten introduction: The timing of introducing gluten into a baby's diet has been explored as a potential risk factor for celiac disease. However, current research does not provide clear evidence that introducing gluten at a certain age increases or decreases the risk of developing the condition.
- Breastfeeding during the first year of life: A 2021 study suggests that breastfeeding during the first year of life may be beneficial in reducing the risk of celiac disease. Breast milk provides essential nutrients and antibodies that support a healthy immune system.
It is important to note that these modifiable risk factors are still being studied, and more research is needed to establish their significance. It is always best to consult with a healthcare professional for personalized advice and guidance.
Common early symptoms of celiac disease include:
- Digestive problems: Gas, diarrhea, and stomach pain are common early symptoms, although they are less common in adults.
- Weight loss: A sharp drop in weight and difficulty keeping weight on are often signs of celiac disease. This is because the body's ability to absorb nutrients is impaired, leading to malnutrition and weight loss.
- Anemia: Anemia is a common feature of celiac disease and is most frequently due to iron deficiency.
Other symptoms that may occur with progression of celiac disease include:
- Extreme tiredness or fatigue.
- Depression or anxiety.
- Missed or irregular menstrual periods.
- Infertility: Studies suggest that untreated celiac disease may cause fertility problems.
- Skin rash: Some individuals may develop a very itchy skin rash with blisters called dermatitis herpetiformis.
- Joint pain and stiffness.
- Weak, brittle bones.
- Seizures.
- Numbness and tingling in the hands and feet.
- Tooth discoloration or loss of enamel.
- Miscarriage.
It's important to note that symptoms can vary widely from person to person, and a person with celiac disease may have multiple symptoms that come and go. If you experience any of these symptoms, it's best to see your doctor for a proper evaluation.
To diagnose celiac disease, doctors commonly perform the following examinations, tests, and procedures:
- Medical history review: Doctors will ask about your symptoms, dietary habits and medical history, including any family history of celiac disease.
- Blood tests: These include tests for specific antibodies associated with celiac disease, such as anti-tissue transglutaminase (tTG) and anti-endomysial antibodies (EMA). Blood tests are most reliable when performed while gluten is still in the diet.
- Genetic tests: These tests can confirm the presence or absence of specific genes associated with celiac disease.
- Intestinal biopsies: A doctor may perform an endoscopy to take samples of the small intestine's lining. This biopsy is the most accurate way to diagnose celiac disease.
It's important to consult with a healthcare professional for an accurate diagnosis and to discuss any additional examinations or tests needed for assessing and determine a treatment plan for celiac disease.
The goals of treatment for celiac disease (CD) are to manage symptoms, promote intestinal healing, prevent complications, and improve overall health. Here are recommended treatments and how they work to achieve these goals:
- Gluten-Free Diet (GFD): The primary treatment for CD is eliminating gluten from the diet. This allows the intestine to heal, reduces symptoms, and prevents further damage caused by gluten ingestion. A registered dietitian may be able to help people identify gluten-free alternatives and create meal plans that provide needed nutrients.
- Medications: In some cases, medications may be recommended to help reduce symptoms or complications of celiac disease. These medications help reduce symptoms but do not heal the intestine, so a GFD is still crucial.
- Dapsone may be prescribed to manage dermatitis herpetiformis, a skin condition associated with CD.
- Osteoporosis medications may be prescribed to help slow or treat bone loss that may occur with CD. In some cases, calcium and vitamins may be recommended. In some other cases, a bisphosphonate medication may be recommended.
- Corticosteroids or immunosuppressant medications to control inflammation during severe celiac flares.
- Vitamin and Mineral Supplements: People with CD may benefit from taking supplements to address nutrient deficiencies caused by malabsorption. These supplements help prevent or correct deficiencies in vitamins and minerals like iron, calcium, and B vitamins.
- Self-care and Health Behavior Changes: Adopting certain health behavior changes can support CD management. These include:
- Reading food labels carefully to identify hidden sources of gluten.
- Identifying gluten-free options when eating out, including letting servers know that you have celia.c disease. Identify a few reliable gluten-free friendly restaurants.
- Avoiding cross-contamination in food preparation.
- Being prepared by carrying a few gluten-free snacks in case you can’t find anything to eat when you are away from home.
- Reading non-food ingredient labels carefully to identify the potential presence of gluten in non-food products, such as in lipstick and make-up products, toothpaste and mouthwash.
- Considering using gluten test strips to test gluten content of new foods.
- Seeking support from healthcare professionals or support groups.
It's important to note that there are currently no specific drug therapies available for CD treatment beyond managing symptoms. Researchers are actively working on developing future treatments to improve long-term outcomes for individuals with CD.
Remember, always consult with your healthcare professional for personalized advice regarding treatment options for your individual situation. Medication dosing may be affected by many factors. Check with your health care professional about dosing for your individual situation. Side effects can occur. Check with your health care professional or read the information provided with your medication for additional sides effect information.
