At the London Osteoporosis Clinic, we are dedicated to uncovering and addressing the various factors that impact bone health. One area that has garnered significant attention in recent years is the relationship between gluten and bone health. For some individuals, gluten can have profound effects on their bones, leading to conditions like osteoporosis. Let’s delve into this connection and explore how understanding gluten impacts bone health can help you maintain strong, healthy bones.

Understanding Gluten and Its Effects

Gluten is a protein found in wheat, barley, and rye. While it is harmless for most people, it can cause serious health issues for others, particularly those with celiac disease or gluten sensitivity. When individuals with these conditions consume gluten, their immune system reacts by damaging the small intestine, leading to a cascade of health problems, including those affecting bone health.

Celiac Disease and Bone Health

Celiac disease is an autoimmune disorder where ingestion of gluten leads to damage in the small intestine. This damage impairs the absorption of nutrients crucial for bone health, such as calcium and vitamin D. Consequently, individuals with untreated celiac disease are at a higher risk of developing osteoporosis and experiencing fractures. Key factors contributing to this increased risk include:

  • Malabsorption of Nutrients: Damage to the small intestine reduces the body’s ability to absorb calcium, vitamin D, magnesium, and other nutrients essential for maintaining strong bones.
  • Chronic Inflammation: The inflammatory response triggered by gluten in celiac disease can affect bone remodelling, the process by which bone tissue is continuously renewed and repaired.
  • Hormonal Imbalances: Celiac disease can lead to changes in hormone levels, such as parathyroid hormone, which plays a critical role in regulating calcium levels and bone metabolism.

Gluten Sensitivity and Bone Health

Even without celiac disease, non-celiac gluten sensitivity can still impact bone health. While the exact mechanisms are not as well understood, evidence suggests that gluten sensitivity can lead to inflammation and nutrient malabsorption, adversely affecting bone health.

Diagnosing and Managing Gluten-Related Bone Issues

Identifying and managing the link between gluten and bone health involves several steps:

  • Diagnosis: Blood tests and intestinal biopsies are commonly used to diagnose celiac disease. For non-celiac gluten sensitivity, diagnosis is often based on symptoms and exclusion of other conditions.
  • Gluten-Free Diet: A strict gluten-free diet is the cornerstone of treatment for celiac disease and gluten sensitivity. Eliminating gluten allows the intestine to heal, improving nutrient absorption and reducing inflammation.
  • Nutrient Supplementation: Individuals with celiac disease may need to supplement their diet with calcium, vitamin D, and other essential nutrients to support bone health during healing.
  • Regular Bone Density Testing: Monitoring bone density through regular DEXA scans can help assess the impact of gluten-related conditions on bone health and guide treatment decisions.

Patient Stories: Real-Life Impacts

At the London Osteoporosis Clinic, we have seen numerous patients whose bone health dramatically improved after addressing gluten-related issues. One such patient, John, a 45-year-old architect, was diagnosed with celiac disease after suffering from recurrent fractures and persistent digestive problems. After transitioning to a gluten-free diet and receiving appropriate nutrient supplementation, John’s bone density significantly improved, and he experienced fewer fractures and better overall health.


The link between gluten and bone health is a critical area of focus for the London Osteoporosis Clinic. For individuals with celiac disease or gluten sensitivity, managing gluten intake is essential for maintaining healthy bones and preventing osteoporosis. Understanding this connection and taking proactive steps can support your bone health and enhance your quality of life.
