Celiac Disease and Osteoporosis Risk

Understanding the Link Between Celiac Disease and Bone Health in Seniors

Celiac disease is an autoimmune disorder triggered by ingesting gluten, a protein found in wheat, barley, and rye. While its most well-known symptoms are digestive in nature, celiac disease can have far-reaching effects on other parts of the body, particularly bone health.

Maintaining strong bones is already a priority for seniors due to natural aging and bone loss. But when celiac disease enters the picture, the risk of weakened bones and fractures increases significantly. This happens because untreated or poorly managed celiac disease interferes with nutrient absorption, particularly calcium and vitamin D, which are essential for maintaining bone density.

How Celiac Disease Affects Bone Density in Older Adults

For seniors with undiagnosed or untreated celiac disease, intestinal damage caused by gluten can prevent the proper absorption of key nutrients from food. The villi—small finger-like structures in the intestines that absorb nutrients—become inflamed and flattened. This malabsorption leads to deficiencies in:

Over time, these deficiencies result in lower bone mineral density (BMD), increasing the likelihood of developing osteopenia or osteoporosis. Studies show that people with celiac disease are more likely to be diagnosed with osteoporosis, even when gastrointestinal symptoms are mild or absent.

What tests measure bone mineral density? The primary test used to measure bone density is a DEXA (Dual-Energy X-ray Absorptiometry) scan. DEXA scans provide two scores: a T-score and a Z-score, which help determine bone density and assess the risk of osteoporosis and osteopenia.

T-score:

Compares your bone density to the average bone density of a healthy young adult (typically ages 25-35).
A T-score of -1.0 or above is considered normal bone density.
A T-score between -1.0 and -2.5 indicates osteopenia (low bone density).
A T-score of -2.5 or below indicates osteoporosis (significantly low bone density).

Z-score:

Compares your bone density to the average bone density of individuals of the same age, sex, and ethnicity.
A Z-score of -2.0 or less may suggest secondary osteoporosis (bone loss caused by a condition or medication).
Z-scores are primarily used for premenopausal women, men under 50, and children, as they are less reliable for diagnosing primary osteoporosis.

In essence, the scores help determine whether bone density is within the normal range, whether it is low (osteopenia), or whether it is high (osteoporosis), and whether the bone loss is related to age or other underlying factors.

Increased Risk of Fractures in Seniors with Celiac

Bone loss in seniors increases the risk of hip, spine, and wrist fractures, which are often difficult to recover from and can lead to long-term disability. Research confirms that people with celiac disease are at a significantly higher risk of fractures, especially when the disease is left undiagnosed into older age.

Two major factors contribute to this:

Nutritional Deficiency: Poor absorption of bone-supportive nutrients weakens the bone structure.
Delayed Diagnosis: Celiac disease in seniors often goes unnoticed due to atypical symptoms such as fatigue, anemia, or joint pain, missing the early window for prevention.

How to Minimize Osteoporosis and Fracture Risk in Seniors with Celiac

The good news? With proper diagnosis and lifelong management, many seniors with celiac disease can maintain or even improve bone health. Here’s how:

1. Nutrient-Rich, Gluten-Free Diet to Strengthen Bones

Maintaining strong bones in seniors with celiac disease starts with healing the gut and ensuring the body can absorb critical nutrients. The first priority is to follow a strict gluten-free diet (GFD), which allows the damaged intestinal lining to recover. Research shows that adhering to a GFD for 1 to 2 years can normalize calcium and vitamin D levels, especially when paired with supplementation. This healing process directly supports the restoration of bone mass and reduces fracture risks, especially in those diagnosed early with low bone mineral density.

But simply removing gluten isn’t enough—eating a bone-building, nutrient-dense diet is essential.

Why Bone-Building Foods Matter

Seniors need higher calcium, vitamin D, magnesium, and protein levels to slow down bone loss and reduce their fall risk. The Recommended Daily Allowance (RDA) for calcium is 1000–1300 mg for adults over age 50, and 600–800 IU of vitamin D. Since the body’s ability to absorb nutrients decreases with age and with celiac-related gut damage, focusing on nutrient-dense, easily absorbable foods becomes even more important.

Top Gluten-Free Foods for Bone Health

Nutrient	Best Gluten-Free Food Sources	Bone Health Benefits
Calcium	Tempeh, tofu with calcium sulfate, white beans, sardines (with bones), kale, bok choy, almonds	Builds and maintains bone structure, crucial for bone mineral density
Vitamin D	Fortified dairy-free milks, egg yolks, wild-caught salmon, cod liver oil, fortified orange juice	Enhances calcium absorption, regulates bone growth and immune function
Magnesium	Pumpkin seeds, chia seeds, spinach, brown rice, avocado	Supports calcium metabolism and bone mineralization
Vitamin K	Brussels sprouts, broccoli, collard greens	Helps in the regulation of bone proteins and supports bone formation
Protein	Eggs, lentils, gluten-free quinoa, chicken, salmon	Essential for maintaining muscle mass and bone repair

Consider Supplements and Monitoring

While food is the foundation, supplements may still be necessary, especially for vitamin D. Have your loved one’s levels checked annually and consult their healthcare provider to tailor dosages as needed. Combining a healing diet with supplements and exercise ensures a comprehensive approach to preventing osteoporosis. The following graphic from gluten.org shows how to build a nutrient-dense plate for bone health.

Consider consulting a registered dietitian specializing in gluten-free care for seniors to create a balanced and safe meal plan.

2. Bone-Building Exercises for Seniors

Exercise programs are not one-size-fits-all. Regular physical activity can help prevent or decelerate bone loss, particularly the progression from osteopenia to osteoporosis. These should always be customized based on the senior’s mobility, health status, and doctor’s advice. It is recommended that a bone density assessment and a fitness evaluation be undergone before starting any exercise routine.

Weight-bearing and muscle-strengthening exercises are key to improving or maintaining bone density in older adults. Seniors with celiac disease should aim for:

Walking: Simple, low-impact, and improves balance and bone strength
Tai Chi or Yoga: Enhances flexibility and reduces fall risk
Strength Training: Resistance bands or light weights help maintain muscle mass and bone stimulation
Balance Exercises: Crucial for fall prevention, especially in those with low bone density

Final Thoughts

Celiac disease can quietly undermine a senior’s bone strength—but it doesn’t have to. With early diagnosis, a strict gluten-free diet, and a tailored exercise routine, caregivers can help aging loved ones avoid complications like osteoporosis and fractures. Regular bone density scans and lab checks for nutrient levels should also be part of an ongoing care plan.

If you’re a caregiver, staying informed and proactive can make all the difference in your loved one’s quality of life.
