Adult rickets, called osteomalacia, softens the bones and usually begins as dull, aching bone pain in the hips, lower back, pelvis, ribs, and legs, along with muscle weakness that makes stairs, standing, and walking harder. Worth tracking daily: where the pain sits and when it worsens, tenderness when you press on a bone, a waddling or unsteady gait, muscle cramps or spasms, unusual fatigue, height loss, and any fracture from a minor bump or fall. Also log contributing factors such as limited sun exposure, low vitamin D or calcium intake, celiac or other malabsorption conditions, bariatric surgery, kidney or liver disease, and long-term use of certain seizure or antacid medications, because there are several factors to consider.

Rickets is often thought of as a childhood condition, but it can affect adults when vitamin D, calcium or phosphate levels are too low. If you’re experiencing unexplained aches, bone pain or weakness, it’s important to know which signs suggest adult rickets and when to get medical advice.
Adult rickets (osteomalacia) results from inadequate mineralization of bone. Common causes include:
Without enough vitamin D, the body can’t absorb calcium and phosphate properly, leading to soft, fragile bones.
Tracking early symptoms helps you and your doctor intervene before complications develop. Note any of the following:
Keeping organized records of your symptoms makes follow-up easier:
Create a daily log noting:
Track lifestyle factors:
Photograph physical changes:
Record lab and imaging results:
Although adult rickets progresses slowly, some signs require prompt evaluation:
If you experience any of these, speak with your doctor right away. For initial guidance, you might try a free, online symptom check, using the doctor approved Ubie Symptom Checker](https://ubiehealth.com/) to help determine urgency.
Your doctor will review your history, perform a physical exam and order tests to confirm adult rickets:
Adult rickets treatment focuses on correcting deficiencies and addressing underlying causes:
Nutritional Therapy
Sunlight Exposure
Treat Underlying Conditions
Physical Therapy
Monitoring
While treating adult rickets, you can also adopt habits to protect your bones:
Regular follow-up is crucial. Schedule visits every 3–6 months until lab values and symptoms improve. After that, an annual check may suffice. Ask your doctor if you need referrals to specialists such as an endocrinologist or rheumatologist.
Adult rickets is treatable, but early recognition of symptoms is key. By tracking pain, weakness, lifestyle factors and lab results, you’ll give your healthcare provider the best chance to correct deficiencies and prevent complications.
If you’re uncertain about your symptoms or severity, consider a free, online symptom check, using the doctor approved Ubie Symptom Checker](https://ubiehealth.com/) for guidance on next steps.
Above all, if you experience severe pain, sudden weakness, fractures or any life-threatening signs, speak to a doctor immediately. Early intervention can make all the difference in restoring bone health and quality of life.
