1. What causes rickets?

• Vitamin D deficiency: Vitamin D helps the body absorb calcium and phosphate from food. Without enough vitamin D, bones can’t mineralize properly, making them soft.

• Calcium and phosphate deficiency: These are key minerals needed to form strong bones. If the body doesn’t get enough from diet, bones can weaken.

• Lack of sunlight: Sunlight helps the skin produce vitamin D. Not getting enough sunlight, especially in regions with long winters, increases the risk of rickets.

2. How does rickets affect bones?

• Weakened bones: Since bones lack the necessary minerals, they become soft and can bend under body weight.

• Bone deformities: This is most noticeable in children as they grow. Legs may become bowed or knock-kneed because their bones aren’t strong enough to support their weight.

• Stunted growth: Since bones are not developing properly, children may be shorter or smaller than expected for their age.

3. Symptoms of rickets

• Bone pain: The weakened bones can cause pain in the legs, spine, pelvis, or other areas.

• Muscle weakness: Low calcium levels also affect muscles, leading to weakness.

• Dental problems: Teeth may be slow to develop, and there can be an increased risk of cavities.

• Skeletal deformities: As mentioned earlier, bowlegs or other bone malformations are common.

4. How is rickets diagnosed?

• Physical exam: Doctors look for signs of bone deformities, delayed growth, or muscle weakness.

• Blood tests: These are used to check vitamin D, calcium, and phosphate levels.

• X-rays: These show bone abnormalities and help confirm rickets.

5. Treatment for rickets

• Vitamin D supplements: These help the body absorb more calcium and phosphate.

• Dietary changes: Foods rich in vitamin D (like fish, eggs, and fortified dairy products) and calcium (such as milk, cheese, and leafy greens) are added to the diet.

• Sun exposure: Spending more time in sunlight helps the body produce natural vitamin D.

• In severe cases: If bone deformities are advanced, braces or surgery may be needed to correct them.

6. Prevention of rickets

• Balanced diet: Ensure that children get enough vitamin D and calcium through food and supplements if necessary.

• Regular sunlight: Encourage outdoor activities to get natural sunlight.

• Health supplements: In regions where vitamin D deficiency is common, supplements may be recommended by doctors to prevent rickets.
