Rickets in Adults: Causes, Symptoms, and Treatment

Rickets, often associated with children, is a condition that affects bone development and strength due to a deficiency of vitamin D, calcium, or phosphate. Although it is more common in children, rickets can also occur in adults, where it is referred to as osteomalacia. This blog will provide a comprehensive overview of rickets in adults, including its causes, symptoms, and treatment options by best orthopedic doctors in Patiala.

Understanding Rickets in Adults

Rickets in adults, or osteomalacia, is a bone disorder characterized by softening of the bones due to inadequate mineralization. This condition can lead to bone pain, fractures, and deformities. The primary cause is a deficiency of vitamin D, essential for absorbing calcium and phosphate from the gastrointestinal tract. Bones cannot properly calcify without sufficient vitamin D, leading to the symptoms and complications associated with osteomalacia.

Causes of Rickets in Adults

There are several potential causes of rickets in adults, most of which relate to deficiencies or issues with vitamin D, calcium, or phosphate:

1. Vitamin D Deficiency

Inadequate Sunlight Exposure: Vitamin D is synthesized in the skin upon exposure to sunlight. Lack of the sun can lead to vitamin D deficiency, especially in people living in higher latitudes, those who spend most of their time indoors, or individuals who cover their skin for cultural or religious reasons.

Dietary Deficiency: Dietary vitamin D intake is essential, especially for those with limited sun exposure. Foods rich in vitamin D include fatty fish, fortified dairy products, and egg yolks. A diet lacking these foods can contribute to deficiency.

Malabsorption: Certain medical conditions can impair vitamin D absorption from the gastrointestinal tract. These conditions include Crohn’s disease, celiac disease, and other gastrointestinal disorders that affect nutrient absorption.

Liver and Kidney Disorders: The liver and kidneys convert vitamin D to its active form. Liver diseases (such as cirrhosis) and kidney disorders (such as chronic kidney disease) can impair this conversion process, leading to deficiency.

2. Calcium Deficiency

Dietary Insufficiency: Calcium is a crucial mineral for bone health. A diet low in calcium can contribute to the development of osteomalacia. Dairy products, leafy green vegetables, and fortified foods are primary dietary sources of calcium.

Malabsorption: Conditions that impair calcium absorption in the intestines, such as celiac disease and inflammatory bowel disease, can lead to a deficiency.

3. Phosphate Deficiency

Dietary Deficiency: Phosphate is another vital mineral for bone health. While dietary phosphate deficiency is rare, it can occur in individuals with very poor nutrition or those who consume large amounts of antacids containing aluminum, which binds phosphate.

Renal Tubular Disorders: Some kidney disorders can cause phosphate wasting, where the kidneys excrete too much phosphate. This can lead to low phosphate levels in the blood and contribute to osteomalacia.

Symptoms of Rickets in Adults

The symptoms of osteomalacia can vary in severity and often develop gradually. Key symptoms include:

1. Bone Pain and Tenderness

Pain in the bones is the most common symptom of osteomalacia. This pain is often dull, aching, and persistent, affecting the lower back, pelvis, hips, legs, and ribs. The pain can be exacerbated by physical activity and is often worse at night.

2. Muscle Weakness

Muscle weakness, particularly in the proximal muscles (those near the body’s trunk), is a common symptom. This weakness can lead to difficulties in performing everyday activities, such as climbing stairs or getting up from a chair.

3. Bone Deformities

In severe cases, osteomalacia can lead to bone deformities. These deformities may include bowed legs, curvature of the spine (kyphosis), and pelvic deformities. These changes result from the softening and bending of bones under the body’s weight.

4. Fractures

Bones weakened by osteomalacia are more susceptible to fractures. These fractures can occur with minimal trauma and are often seen in the ribs, hips, and vertebrae.

5. Difficulty Walking

Due to bone pain, muscle weakness, and potential deformities, individuals with osteomalacia may experience difficulty walking and a waddling gait.

Diagnosing Rickets in Adults

The diagnosis of osteomalacia involves a combination of clinical evaluation, laboratory tests, and imaging studies:

1. Medical History and Physical Examination

A thorough medical history and physical examination are crucial. The physician will inquire about dietary habits, sun exposure, medical conditions, and any medications that might affect bone health.

2. Laboratory Tests

Blood Tests: Blood tests are essential for diagnosing osteomalacia. Key tests include:

  • Serum 25-hydroxyvitamin D: This test measures the vitamin D level in the blood and is the most reliable indicator of vitamin D status.

  • Calcium and Phosphate Levels: Low calcium and phosphate levels in the blood can indicate a deficiency contributing to osteomalacia.

  • Parathyroid Hormone (PTH): Elevated PTH levels can indicate secondary hyperparathyroidism, which can occur in response to low calcium levels and contribute to bone demineralization.

Urine Tests: Urine tests can help assess phosphate excretion and identify any renal tubular disorders contributing to phosphate wasting.

3. Imaging Studies

X-rays: X-rays can reveal characteristic changes in the bones, such as pseudofractures (Looser’s zones) and bone deformities.

Bone Density Scan: A bone density scan (DEXA scan) can measure bone mineral density and help assess the severity of bone loss.

4. Bone Biopsy

In rare cases, a bone biopsy may be performed to confirm the diagnosis of osteomalacia. This involves taking a small sample of bone tissue and examining it under a microscope to assess the degree of mineralization.

Treatment of Rickets in Adults

The treatment of osteomalacia aims to address the underlying cause of the condition and restore normal bone health. This typically involves a combination of dietary changes, supplements, lifestyle modifications, and, in some cases, medical interventions:

1. Vitamin D Supplementation

Oral Supplements: The cornerstone of osteomalacia treatment is vitamin D supplementation. The dosage and duration of supplementation depend on the severity of the deficiency and the underlying cause. High-dose vitamin D supplements are often prescribed initially, followed by maintenance doses to ensure adequate levels.

Sunlight Exposure: Increasing exposure to sunlight can help boost vitamin D levels. Spending time outdoors in the sun, especially during midday, can enhance the skin’s production of vitamin D. However, it’s essential to balance sun exposure with the risk of skin damage and skin cancer.

2. Calcium and Phosphate Supplementation

Calcium Supplements: Calcium supplements may be prescribed to individuals with low dietary intake or absorption issues. These supplements help ensure the body has enough calcium to support bone mineralization.

Phosphate Supplements: In cases of phosphate deficiency, phosphate supplements may be necessary. This is particularly relevant for individuals with renal tubular disorders or other conditions causing phosphate wasting.

3. Dietary Changes

Dietary Sources of Vitamin D: It is beneficial to incorporate foods rich in vitamin D into the diet. These include fatty fish (such as salmon and mackerel), fortified dairy products, cereals, and egg yolks.

Dietary Sources of Calcium: A calcium-rich diet is crucial for bone health. Good sources of calcium include dairy products (goat milk, cheese, yogurt), leafy green vegetables (kale, broccoli), and fortified foods (orange juice, tofu).

4. Addressing Underlying Medical Conditions

Gastrointestinal Disorders: Treating underlying gastrointestinal disorders that impair nutrient absorption is essential. This may involve managing conditions like celiac disease or Crohn’s disease with appropriate medications and dietary modifications.

Liver and Kidney Disorders: Addressing liver and kidney disorders that affect vitamin D metabolism is crucial. This may involve medical management of chronic liver or kidney disease and specific treatments to support vitamin D activation.

5. Pain Management and Physical Therapy

Pain Relief: Pain management strategies, including using analgesics and anti-inflammatory medications, can help alleviate bone pain and improve quality of life.

Physical Therapy: Physical therapy can benefit individuals with muscle weakness and mobility issues. A physical therapist can develop a tailored exercise program to improve strength, flexibility, and mobility.

Prevention of Rickets in Adults

Preventing osteomalacia involves ensuring adequate intake of vitamin D, calcium, and phosphate, along with regular monitoring of bone health:

1. Regular Sun Exposure

Regular, moderate sun exposure is one of the best ways to maintain adequate vitamin D levels. Aim for about 10-30 minutes of sunlight exposure several times a week, depending on skin type, geographical location, and weather conditions.

2. Balanced Diet

Maintaining a balanced diet with sufficient amounts of vitamin D, calcium, and phosphate is crucial for bone health. If dietary intake is inadequate, consider incorporating fortified foods and supplements.

3. Regular Health Check-Ups

Regular health check-ups can help detect and address deficiencies or medical conditions affecting bone health. Routine blood tests can monitor vitamin D, calcium, and phosphate levels, allowing for timely intervention.

4. Lifestyle Modifications

Adopting a healthy lifestyle that includes regular physical activity, avoiding smoking, and limiting alcohol intake can support overall bone health and reduce the risk of osteomalacia.

Conclusion
