What Are the Symptoms of Rickets in Adults?

Rickets is often thought of as a childhood disease, but adults can develop a similar condition known as osteomalacia. Both arise from inadequate vitamin D, calcium or phosphate, leading to softening of the bones. When adults experience bone softening, the signs and discomfort can closely mirror what pediatricians call rickets in children. Understanding the key warning signs—often referred to as rickets in adults symptoms—can help you recognize the problem early and seek the right care.

Why Adults Can Develop “Rickets”

In adults, true rickets (which affects growing bones at the growth plates) does not occur. Instead, vitamin D deficiency or impaired mineral metabolism causes osteomalacia. Common triggers include:

• Inadequate sun exposure (vitamin D is produced in skin upon sunlight contact)
• Poor dietary intake of vitamin D or calcium
• Malabsorption conditions (celiac disease, inflammatory bowel disease)
• Chronic liver or kidney disease (these organs activate vitamin D)
• Certain medications (e.g., anticonvulsants, some weight-loss drugs)

When your body can’t maintain normal levels of calcium or phosphate, bones become softer and more prone to bending, pain and fractures. Recognizing rickets in adults symptoms is the first step toward diagnosis and treatment.

Key Rickets in Adults Symptoms

Symptoms of adult osteomalacia can develop gradually. You may dismiss early signs as “normal aging” or muscle fatigue. Pay attention if you notice:

• Bone Pain and Tenderness
  • Deep, aching pain in hips, lower back, pelvis or legs
  • Worse at night or when putting weight on the affected area
  • Tenderness when pressing along the ribs or pelvic bones

• Muscle Weakness
  • Difficulty climbing stairs or rising from a seated position
  • Trouble lifting objects overhead
  • Frequent tripping or balance issues

• Frequent or Unusual Fractures
  • Stress fractures in the ribs, wrists or hips with minimal trauma
  • Small cracks in weight-bearing bones that cause sudden pain

• Bone Deformities (in severe, prolonged cases)
  • Forward-leaning posture (pelvic tilt)
  • Curvature of the spine (mild kyphosis)
  • Waddling gait due to hip weakness

• Dental Problems
  • Delayed tooth eruption (in those with lifelong deficiency)
  • Increased tooth decay or gum issues

• General Fatigue and Malaise
  • Persistent tiredness, even after adequate sleep
  • Low energy for everyday activities

• Muscle Cramps or Spasms
  • Involuntary twitching or tightening, especially in the legs or back
  • Often related to low blood calcium levels

• Numbness or Tingling
  • “Pins and needles” sensation around the mouth or in the hands
  • Can signal hypocalcemia (low calcium)

If you experience several of these symptoms together, it may indicate weakening of your bones from insufficient mineralization. Early recognition of rickets in adults symptoms can prevent progression to severe bone damage.

How Doctors Confirm the Diagnosis

A healthcare provider will combine your history and symptoms with laboratory tests and imaging to confirm osteomalacia:

1. Blood tests

   • Low vitamin D (25-hydroxyvitamin D)
   • Low or normal calcium
   • Low phosphate
   • Elevated alkaline phosphatase
   • Possible elevated parathyroid hormone (PTH)

2. Urine tests

   • May show increased calcium or phosphate loss

3. X-rays or bone scans

   • Looser’s zones (pseudofractures) in long bones
   • Generalized bone thinning

4. DEXA scan (bone density)

   • Assesses bone mineral density to evaluate osteoporosis vs. osteomalacia

Managing and Treating Adult Osteomalacia

Treatment focuses on restoring normal vitamin D, calcium and phosphate levels:

• Vitamin D Supplementation
  • High-dose D2 or D3 under medical supervision
  • Maintenance dosing thereafter

• Calcium and Phosphate Supplements
  • Oral calcium carbonate or citrate
  • Phosphate salts if levels remain low

• Dietary Adjustments
  • Increase fatty fish (salmon, mackerel), fortified milk and cereals
  • Include leafy greens, yogurt and cheese for calcium

• Sunlight Exposure
  • 10–30 minutes of midday sun, 2–3 times per week
  • Skin tone and location influence required exposure

• Address Underlying Causes
  • Treat malabsorption (gluten-free diet for celiac, etc.)
  • Optimize liver or kidney function when possible
  • Review and adjust medications that interfere with vitamin D

• Physical Therapy
  • Strengthening exercises for hip and thigh muscles
  • Balance training to reduce fall risk

With proper supplementation and lifestyle changes, bone pain usually improves within weeks. Full mineralization may take several months, so follow-up with your doctor is essential.

When to Seek Immediate Medical Attention

While many cases respond to outpatient treatment, some situations require urgent care:

• Severe, sudden bone pain limiting your ability to walk
• New, unexplained fractures or deformities
• Signs of hypocalcemia (severe muscle cramps, seizures)
• Persistent, worsening fatigue with no clear cause

If you’re unsure whether your symptoms are serious, consider a free, online symptom check, using the doctor approved Ubie Symptom Checker. It can help you decide if you need immediate medical evaluation.

Tips to Reduce Anxiety and Take Control

It’s natural to worry when you learn about bone-weakening conditions. Keep in mind:

• Rickets in adults symptoms develop slowly and are reversible with treatment.
• Early detection means faster relief of pain and restored strength.
• Simple changes (diet, supplements, safe sun exposure) make a big difference.
• Your healthcare team will guide you through testing and treatment steps.

Maintaining bone health is a lifelong effort. Regular check-ups, balanced nutrition and safe sunlight can help prevent recurrence.

Next Steps: Speak to a Doctor

If you recognize any combination of rickets in adults symptoms—especially persistent bone pain, muscle weakness or frequent fractures—talk to a healthcare professional. Only a doctor can:

• Order the right tests
• Rule out other conditions (osteoporosis, arthritis, cancer)
• Prescribe and adjust supplements safely
• Monitor your progress and prevent complications

Never ignore severe or rapidly worsening symptoms. Early intervention can restore your bone strength and quality of life.
