Core Results of Vitamin D Deficiency
When faced with the question, "Which of the following is a result of vitamin D deficiency quizlet?", the most direct and accurate responses involve two primary bone disorders: rickets in children and osteomalacia in adults. These conditions arise because vitamin D is essential for the body to absorb calcium and phosphorus, the minerals needed to build and maintain strong bones. Without sufficient vitamin D, the body cannot properly mineralize bone tissue, leading to structural problems.
Rickets: The Result in Children
Rickets is a childhood disorder characterized by weak, softened bones. A vitamin D deficiency during childhood can lead to significant skeletal deformities, such as bowed legs and bone pain. Breastfed infants not receiving supplements and children with darker skin are at higher risk.
Osteomalacia: The Adult Equivalent
In adults, severe vitamin D deficiency results in osteomalacia. This leads to poorly mineralized, soft bones, causing chronic muscle aches, bone pain, and an increased risk of fractures.
Beyond the Bones: Other Symptoms of Deficiency
Vitamin D also affects the nervous, musculoskeletal, and immune systems, leading to other potential symptoms:
- Muscle Pain and Weakness: Deficiency can cause muscle cramps, aches, and weakness, particularly in the upper arms and thighs.
- Chronic Fatigue: Low vitamin D levels have been linked to persistent tiredness and fatigue.
- Depression and Mood Changes: Evidence suggests a connection between low vitamin D and an increased risk of depressive episodes, as vitamin D impacts brain function and mood.
- Frequent Infections: Vitamin D is crucial for immune function, and a deficiency can weaken the immune system, leading to more frequent illnesses.
- Slow Wound Healing: Vitamin D is involved in inflammation control and skin formation, so deficiency can delay wound healing.
Comparing Rickets and Osteomalacia
| Feature | Rickets | Osteomalacia |
|---|---|---|
| Affected Group | Children (growing bones) | Adults (mature bones) |
| Skeletal Impact | Soft, weak bones leading to bending and deformities like bowed legs or spinal curvature. | Poorly mineralized, soft bones leading to bone pain and increased fracture risk. |
| Common Symptoms | Bowed legs, bone pain, delayed walking, and muscle weakness. | Chronic muscle and bone pain (especially in the back), muscle weakness, and fatigue. |
| Joint Involvement | Can cause joint deformities, such as widened wrists and ankles. | May cause pain in the joints but typically not the deformities seen in children. |
| Cause | Extreme and prolonged vitamin D and/or calcium deficiency during childhood. | Severe and prolonged vitamin D deficiency in adulthood. |
Conclusion: A Widespread and Treatable Concern
Ultimately, the results of vitamin D deficiency are diverse, ranging from classic bone-softening diseases like rickets and osteomalacia to more systemic issues such as muscle weakness, chronic fatigue, and a compromised immune system. The quiz-style question points to a well-established medical fact that a lack of this crucial vitamin impairs the body's ability to utilize calcium effectively. While serious, vitamin D deficiency is both preventable and treatable through increased sun exposure (with caution), fortified foods, and dietary supplements. Anyone with symptoms or risk factors should consult a healthcare provider for a blood test to determine the appropriate course of action.

Key Results of Vitamin D Deficiency
Key results include rickets in children and osteomalacia in adults, both causing softened bones. Bone pain and increased fracture risk are common due to impaired calcium absorption. Muscle weakness and aches can occur, along with fatigue and low mood. A deficiency also compromises the immune system, leading to more frequent infections.
FAQs
Q: What is the main cause of nutritional vitamin D deficiency? A: The main cause of nutritional vitamin D deficiency is inadequate exposure to sunlight, as well as insufficient dietary intake of vitamin D.
Q: How is vitamin D deficiency diagnosed? A: A healthcare provider can diagnose vitamin D deficiency with a blood test that measures the level of 25-hydroxyvitamin D in your blood.
Q: What are the main sources of vitamin D? A: Primary sources include sunlight exposure, certain foods like fatty fish and egg yolks, and fortified foods such as milk and cereal.
Q: Can vitamin D deficiency be cured? A: Yes, vitamin D deficiency is highly treatable through supplements and increased exposure to sunlight, which can restore normal levels over time.
Q: Who is at a higher risk of developing vitamin D deficiency? A: Individuals with darker skin, the elderly, those with limited sun exposure, and people with conditions like obesity or malabsorption disorders are at a higher risk.
Q: Can vitamin D deficiency affect mental health? A: Yes, research has suggested a link between low vitamin D levels and mood changes, including an increased risk of depression.
Q: What is the difference between rickets and osteomalacia? A: Rickets affects growing children, causing skeletal deformities, while osteomalacia affects adults, causing soft bones, bone pain, and muscle weakness.
Q: Why do older adults have a higher risk of vitamin D deficiency? A: As people age, their skin becomes less efficient at producing vitamin D from sunlight, and they tend to spend less time outdoors.
