Rickets: Causes, Symptoms, Treatment, and Prevention

Rickets is a skeletal disorder provoked by a deficiency of vitamin D, phosphate, or calcium, which are essential nutrients for strong and healthy bone development. This condition weakens bones, slows growth, and often leads to skeletal deformities.

Symptoms

• Pain in the bones of the arms, legs, pelgvis, or spine
• Stunted growth and short stature
• Difficulty walking and running
• Slow development of motor skills
• Bone fractures
• Muscle cramps
• Teeth deformities, such as:
  • Delayed tooth formation
  • Holes in the enamel
  • Defects in the tooth structure
  • An increase in cavities
• Skeletal deformities, including:
  • An oddly shaped skull
  • Bowlegs
  • Bumps in the ribcage
  • A protruding breastbone
  • A curved spine
  • Pelvic deformities

Causes

Vitamin D is important in assisting the body in absorbing calcium and phosphate from the intestines. While foods like milk, eggs, and fish provide vitamin D, the body also produces it when exposed to sunlight. Without enough vitamin D, maintaining adequate calcium and phosphate levels becomes difficult.

In response, the body releases hormones that draw these minerals from the bones, making them weak and soft. As a result, your body may struggle to process vitamin D or maintain adequate calcium levels.

Some medical disorders, like celiac disease, inflammatory bowel disease, cystic fibrosis, and kidney disorders, can interrupt the body’s ability to absorb or use vitamin D properly, increasing the risk of rickets.

Risk Factors

Various factors account for an increased risk of developing rickets, including the following.

Age

Rickets primarily affects children between six and thirty-six months, as their growing bodies require sufficient nutrients for proper bone development. Children at higher risk include those with limited sun exposure, those following a vegetarian diet, or those who do not consume dairy products.

Diet

A diet lacking fish, eggs, or milk increases the risk of rickets, especially for those following a vegetarian diet. Individuals who have difficulty digesting milk or are allergic to lactose are also more susceptible. Infants who rely solely on breast milk may develop vitamin D deficiency since breast milk does not provide enough of this nutrient to prevent rickets.

Skin Color

Children with darker skin, including those of African, Pacific Islander, and Middle Eastern descent, have a higher risk of rickets. Darker skin produces less vitamin D in response to sunlight than lighter skin, increasing the probability of deficiency.

Geographic Location

People living in areas with limited sunlight exposure are at a greater risk of developing rickets. Those who spend most of their time indoors during daylight hours also have reduced vitamin D production, making them more susceptible.

Genetic Factors

Some forms of rickets are inherited. Hereditary rickets, a genetic disorder, affects the kidneys’ ability to absorb phosphate, leading to weak and soft bones.

Diagnosis

A doctor diagnoses rickets through a physical examination. The doctor will check for bone pain by slightly pressing on the bones. The doctor might also conduct a few tests to diagnose rickets. Some of these tests include:

• Blood tests, for measuring the levels of calcium and phosphate in the blood
• Bone X-rays to check for bone deformities

In standard cases, a small bone sample is taken and analyzed in a lab through a procedure known as a bone biopsy.

Treatment

Rickets treatment focuses on making bones stronger and correcting the lack of important nutrients.

Vitamin and mineral supplements

Doctors treat rickets with vitamin D and calcium supplements. Some children may also need phosphorus supplements. These nutrients help bones grow strong and healthy. Always follow the doctor’s advice on dosage because too much vitamin D can be harmful.

Children should also eat foods rich in vitamin D and calcium, such as milk, cereal, and fatty fish.

Sunlight exposure

The body uses sunlight to prepare Vitamin D. Doctors may suggest safe sunlight exposure to help improve vitamin D levels.

Monitoring progress

Doctors check recovery with blood tests and X-rays. Most children start to show improvement within about a week after treatment begins.

Braces or surgery

Mild bone deformities often improve as the child grows. Some children may need braces to help straighten their bones. Sometimes, surgery may be required in severe cases to correct bone shape.

Treatment for underlying conditions

If rickets is caused by a genetic disorder or another medical condition, a specialist may provide additional treatment and medicines.

Early treatment gives the best results. When treated during childhood, many bone changes improve or go away over time.

Healing Process in Children

Most children show signs of improvement from rickets within a week of treatment. When addressed early, skeletal defects often heal or gradually disappear over time. However, if rickets remains untreated during the child’s growth phase, skeletal abnormalities may become permanent.

Prevention

The best way to prevent rickets is to take in a wholesome diet containing adequate amounts of calcium, phosphorus, and vitamin D. It is crucial for people with kidney problems to keep a tab on their body’s calcium and phosphate levels.

Although sunlight is vital for the body’s production of vitamin D, it is indispensable to understand that too much sunlight can damage the skin. Therefore, it is advised to use sunscreen to treat damaged skin.
