MCQ Detailed View

Vitamin D is a fat-soluble vitamin essential for strong bones and teeth. It helps the body absorb calcium and phosphorus from food, which are necessary minerals for bone strength. Without enough vitamin D, the body cannot properly use calcium, leading to weak and brittle bones.

A deficiency of vitamin D can cause several problems, especially related to the skeletal system:

• 
  

  Osteoporosis: A condition where bones become fragile and more likely to break.

  
  


• 
  

  Fractures: Weak bones are more prone to cracks and breaks, even from minor falls or injuries.

  
  


• 
  

  Rickets (in children): Soft and deformed bones.

  
  

Vitamin D deficiency usually occurs due to:

1. 
   

   Limited sunlight exposure: Vitamin D is produced in the skin when exposed to sunlight.

   
   


2. 
   

   Poor diet: Lack of foods rich in vitamin D, such as fish, egg yolks, and fortified milk.

   
   


3. 
   

   Health conditions: Diseases affecting fat absorption or liver/kidney function can reduce vitamin D levels.

   
   

It is important to note that vitamin D deficiency does not directly cause gum disease, skin problems, or eye-sighted weakness. Those issues are related to other vitamins or conditions:

• 
  

  Gum disease: Linked to vitamin C deficiency.

  
  


• 
  

  Skin problems: Can occur from vitamin A or other causes.

  
  


• 
  

  Eye problems: Linked to vitamin A deficiency.

  
  

To prevent vitamin D deficiency, people should spend some time in sunlight, eat foods rich in vitamin D, and take supplements if recommended by a doctor.

In summary, the correct answer is C. Osteoporosis and fractures, as vitamin D is crucial for maintaining strong and healthy bones.
