Overview of Rickets

Rickets is a medical condition that leads to the softening and weakening of bones in children, usually due to extreme vitamin D deficiency. This condition interferes with calcium and phosphate balance, which are vital for healthy bone development. If not treated early, rickets disease can cause bone deformities, poor growth and other serious complications. In adults, a similar condition called osteomalacia may occur. Both highlight how essential vitamin D, sunlight and a nutritious diet are to maintaining bone health.

Types of Rickets

1. Nutritional Rickets: Caused by a lack of vitamin D, calcium or phosphate in the diet.

2. Hypophosphatemic Rickets: A genetic disorder where the kidneys excrete too much phosphate.

3. Vitamin D–Dependent Rickets: A rare genetic form where the body can’t process vitamin D properly.

4. Osteomalacia: The adult version of rickets, involving softening of bones due to vitamin D deficiency.

Symptoms of Rickets

Bone pain or tenderness in arms, legs, spine or pelvis.

Delayed growth and short stature in children.

Weakness and fatigue due to muscle softness.

Skeletal deformities like bowed legs or thickened wrists and ankles.

Dental problems, including delayed tooth formation and defects.

Rickety rosary – Bony bumps along the ribs.

Causes of Rickets

Insufficient vitamin D intake from diet or supplements.

Limited exposure to sunlight, especially in colder or cloudy climates.

Malabsorption disorders like celiac disease or Crohn’s.

Chronic kidney problems affecting vitamin D activation.

Genetic defects affecting phosphate processing.

Certain medications interfering with vitamin D metabolism.

Complications in Rickets

Permanent bone deformities if untreated during growth.

Increased risk of bone fractures due to weakened structure.

Skeletal pain and reduced mobility.

Growth disturbances and delayed milestones in children.

Dental issues, including increased cavity risk.

Osteomalacia and brittle bones in adults.

Risk Factors of Rickets

Dark-skinned individuals (reduced ability to make vitamin D from sunlight).

Premature babies who miss out on maternal calcium and vitamin D stores.

Breastfed infants without vitamin D supplementation.

Lack of sun exposure due to geographical location or lifestyle.

Vegetarian or vegan diets low in vitamin D and calcium.

Genetic family history of hypophosphatemic rickets.

Preventions of Rickets

Ensure adequate sunlight exposure (at least 10–30 minutes, several times a week).

Include vitamin D-rich foods: eggs, fatty fish, fortified dairy, and cereals.

Provide supplements in high-risk groups like infants or elderly.

Early screening for children with family history or signs of poor growth.

Public health awareness about what causes rickets disease and how to prevent it.
