In the clinical landscape of the United Kingdom, coeliac disease is recognised as a condition that can manifest at any point in a person’s life. From a medical perspective, coeliac disease is a permanent autoimmune disorder triggered by the ingestion of gluten in genetically predisposed individuals. While it was once thought to be primarily a childhood illness, we now understand that the onset of symptoms can occur in infancy, adolescence, or late adulthood. In fact, many individuals are now being diagnosed in their 40s, 50s, or even 70s. Whether the disease appears in a toddler or an elderly patient, the underlying biological mechanism of intestinal damage remains the same, though the clinical symptoms often vary significantly depending on the age of the patient.
As a physician with experience in general medicine, surgery, and emergency care, I have managed patients across the entire age spectrum who were suffering from undiagnosed malabsorption. Whether in the hospital ward or an intensive care unit, recognising that coeliac disease does not have an age limit is essential for timely intervention. This article explores how the condition presents in both children and adults.

Coeliac Disease in Children and Infants
In children, symptoms typically appear shortly after gluten is introduced into the diet, usually around six months of age. Because children are in a critical stage of physical development, the signs of coeliac disease are often related to growth and nutrition.
- Failure to Thrive: Slow growth or a drop in the expected weight gain for their age.
- Digestive Distress: Chronic diarrhoea, foul smelling stools, and abdominal bloating.
- Behavioural Changes: Irritability and lack of energy are common clinical indicators in young children.
- Dental Enamel Defects: Permanent teeth may emerge with yellow or brown spots or thin enamel.
In my experience in clinical assessment, early diagnosis in childhood is vital to prevent permanent height deficits or delayed puberty.
Coeliac Disease in Adults and Seniors
Adults often present with what we call extra-intestinal symptoms, meaning the issues occur outside of the digestive tract. This can make the condition harder to identify if a clinician is only looking for stomach pain.
- Iron Deficiency Anaemia: This is one of the most common signs in adults and may be the only symptom present.
- Osteoporosis: Reduced bone density due to poor calcium and vitamin D absorption.
- Neurological Issues: Peripheral neuropathy (numbness in hands and feet) or ataxia (balance issues).
- Dermatitis Herpetiformis: A chronic, itchy, blistering skin rash linked to gluten ingestion.
Adults are also more likely to have silent coeliac disease, where the intestinal damage is occurring without any obvious symptoms until a complication like a bone fracture occurs.
Why Does It Develop Later in Life?
Many adults wonder why they could eat gluten for decades without an issue. Clinicians believe that for some, the genetic switch is turned on by an environmental trigger later in life. These triggers can include:
- Gastrointestinal Infections: A severe viral or bacterial gut infection.
- Physical Trauma: Such as major surgery or a severe injury.
- Hormonal Shifts: Pregnancy and childbirth have been noted as common triggering events for women.
- Changes in the Microbiome: Shifts in gut bacteria that alter the intestinal lining.
Integrating Clinical Tracking and Education
As a medical educator, I advocate for lifelong vigilance regardless of your age. Utilising digital health diaries to track your symptoms, nutritional levels, and family history provides your GP with the objective data needed to initiate screening. In the hospital, we use data to guide recovery for both young and old; in your personal life, this data allows you to monitor how your body responds to a gluten free diet over many years. This transparency ensures that the structural damage to your intestines is reversing and your long term health is protected.
Emergency Guidance: Identifying Red Flags
Whether you are a parent or an adult patient, you must recognise acute symptoms. Seek emergency care immediately if you experience:
- Severe Abdominal Pain: Sudden, agonising pain that could indicate a bowel obstruction.
- Uncontrolled Vomiting or Diarrhoea: Leading to severe dehydration and electrolyte imbalances.
- Sudden Neurological Deficits: Numbness, weakness, or difficulty walking.
- Signs of a Silent Heart Attack: Such as sudden profound nausea, weakness, and chest or jaw pressure, which can sometimes be confused with severe gastric distress.
In these situations, call 999 or attend your nearest Accident and Emergency department immediately.
To Summarise
Both children and adults can develop coeliac disease, though the symptoms often vary by age. In children, the focus is often on growth and digestive issues, while adults frequently experience anaemia, bone loss, or neurological symptoms. In the UK, clinicians like Dr. Stefan Petrov emphasise that coeliac disease should be considered a possibility regardless of a patient’s age. By utilising digital tracking tools to document symptoms and maintaining a high index of suspicion in high risk groups, you can ensure a timely diagnosis and a healthy future through a strict gluten free lifestyle.
Can a baby be born with coeliac disease?
No. A baby is born with the genetic predisposition, but the disease only activates once they begin eating foods containing gluten.
Is coeliac disease more severe in adults?
Not necessarily, but adults may have had the condition undiagnosed for longer, leading to more complications like osteoporosis or chronic anaemia.
Why was I diagnosed at 60 if I have had this my whole life?
It is possible you had silent coeliac disease for years, or that your condition was only recently triggered by an environmental factor or a change in your immune system.
Do children outgrow coeliac disease?
No. Coeliac disease is a lifelong autoimmune condition. Even if symptoms disappear on a gluten free diet, the immune system will always react to gluten.
