A child typically gets rickets due to a significant lack of vitamin D or calcium. This is the most common cause, according to the NHS.
The Role of Vitamin D and Calcium
Vitamin D is absolutely essential for the proper formation of strong and healthy bones in children. When a child doesn't get enough vitamin D or calcium, their bones can become soft and weak, leading to the condition known as rickets.
Causes Explained
Based on the provided information from the NHS, the primary causes revolve around deficiencies:
- Lack of Vitamin D: This is a major factor. Vitamin D helps the body absorb calcium and phosphate, which are needed for healthy bones.
- Lack of Calcium: Calcium is the main building block of bones. Insufficient calcium intake directly impacts bone strength.
Where Vitamin D Comes From
Getting enough vitamin D is crucial, and there are a few key ways children obtain it:
- Sunlight Exposure: A large amount of vitamin D is made when the skin is exposed to sunlight.
- Certain Foods: While sunlight is a primary source, some foods also contain vitamin D. The reference specifically mentions:
- Oily fish
- Eggs
Importance for Bone Health
Without sufficient vitamin D, even if a child consumes enough calcium, their body struggles to use it effectively for bone growth and strength. This deficiency weakens the developing bones, leading to the symptoms of rickets.
In summary, rickets in children is primarily caused by not having enough vitamin D or calcium, which are vital nutrients for building strong and healthy bones.
