If you regularly experience bloating, abdominal pain, diarrhea, fatigue, or unexplained weight loss after eating foods containing gluten, the proteins found in wheat, rye, and barley, you may be wondering whether it’s more than just a sensitive stomach. Celiac disease is a serious autoimmune condition that affects the digestive system and can lead to long-term health complications if left untreated.
At Charleston GI in Charleston, SC, our experienced gastroenterology team helps patients find the root cause of their symptoms through a thorough evaluation and advanced diagnostic testing. Understanding the warning signs of celiac disease is the first step toward protecting your digestive health and improving your quality of life.
What is Celiac Disease?
When someone with celiac disease eats gluten, it triggers an immune response in the small intestine. This reaction can damage the lining of the small intestine over time, harming its ability to absorb nutrients, which is also known as malabsorption.
Intestinal damage often leads to symptoms like diarrhea, fatigue, weight loss, bloating, and anemia. While some people experience classic digestive symptoms, others may have subtle or even non-digestive signs, like anxiety, depression, headaches, or rashes, making diagnosis more challenging.
Celiac disease can result in serious complications if you don’t treat it or manage its symptoms, like malabsorption. Malabsorption can also impact growth and development in children with celiac disease.
While there is currently no cure for celiac disease, most individuals can successfully manage their symptoms and give their intestines the opportunity to heal by strictly sticking to a gluten-free diet.
Celiac Disease Symptoms: Beyond the Digestive Tract
Symptoms of celiac disease can vary greatly from person to person and can look different between children and adults, as well.
- Common digestive symptoms in adults:
- Diarrhea
- Fatigue
- Weight loss
- Bloating and gas
- Belly pain
- Nausea and vomiting
- Constipation
Non-digestive symptoms in adults:
Over half of adults with celiac disease experience symptoms unrelated to the digestive system. These can include:
- Nutritional Deficiencies: Anemia, often from iron deficiency due to poor absorption, and loss or softening of bone (osteoporosis or osteomalacia)
- Skin and Mouth Issues: An itchy, blistery skin rash (dermatitis herpetiformis) and mouth ulcers
- Neurological and Systemic Effects: Headaches, fatigue, nervous system injury, such as numbness and tingling in the extremities, balance problems, cognitive impairment, joint pain, and reduced spleen function (hyposplenism)
- Other Signs: Elevated liver enzymes
Children with celiac disease often experience different symptoms than adults. The most common issues are digestive problems, such as:
- Chronic diarrhea
- Nausea and vomiting
- A swollen belly
- Constipation
- Gas
- Pale, foul-smelling stools
Additionally, not being able to absorb nutrients properly can lead to other complications, including:
- In infants: Failure to thrive
- Physical symptoms: Weight loss, anemia, short stature, and tooth enamel damage
- Developmental issues: Delayed puberty
- Behavioral/Neurological symptoms: Irritability, headaches, lack of muscle coordination, seizures, learning disabilities, and attention-deficit/hyperactivity disorder (ADHD)
When to Seek Medical Advice
If you experience chronic diarrhea or digestive discomfort lasting more than two weeks, talk to your doctor.
When to consult a child’s healthcare team:
Seek advice from your child’s healthcare provider if your child experiences any of the following:
- Paleness
- Irritability
- Failure to grow (failing to thrive)
- A distended abdomen (potbelly)
- Bulky, foul-smelling stools
Important note before making changes to your diet:
It is crucial to consult your healthcare team before starting a gluten-free diet. Reducing or eliminating gluten intake prior to testing for celiac disease can interfere with the accuracy of the test results.
Family history and risk factors:
Since celiac disease often runs in families, discuss testing with your doctor if a family member has the condition.
Testing for Celiac Disease
Testing for celiac disease involves a simple blood test. If a person with celiac disease consumes gluten, their immune system reacts by producing antibodies, viewing the gluten as a threat. Consequently, a higher-than-normal level of these specific antibodies will be present in the blood. It is important to be on a gluten-containing diet for this antibody test to ensure accurate results.
Don’t Ignore the Signs of Celiac Disease
Living with ongoing digestive discomfort, fatigue, or unexplained health changes can be frustrating, especially when you don’t know the cause.
If you suspect that gluten may be triggering your symptoms, the first step is seeking an evaluation from a gastroenterologist rather than starting a gluten-free diet on your own, which can interfere with your test results. At Charleston GI in Charleston, SC, our experienced team provides thorough diagnostic testing, personalized treatment plans, and ongoing support to help you manage celiac disease and protect your long-term digestive health.
Don’t ignore persistent symptoms. Early diagnosis and proper care can help you feel better, prevent complications, and get back to living comfortably and confidently. Schedule your appointment today.
