Rickets awareness

Overview

Rickets is a condition that affects children's bones, making them soft, weak, and deformed. It happens when growing bones do not get enough vitamin D or calcium, which are needed for strong, healthy bones.

Rickets is rare in many developed countries, but it can still happen, especially in children with limited sun exposure, a poor diet, or certain medical conditions. It is more common in parts of the world where malnutrition is widespread.

Rickets mainly affects infants and young children, especially those with dark skin living in cloudy climates, those who spend most of their time indoors, or children who follow a strict vegetarian or vegan diet without enough vitamin D. It can also affect breastfed babies whose mothers are low in vitamin D.

Symptoms

Common symptoms

• Bone pain or tenderness, especially in the arms, legs, pelvis, or spine
• Delayed growth and short stature
• Soft, weak bones that can lead to bowlegs or knock-knees
• Muscle weakness and cramps
• Delayed teething and dental problems

Symptoms in children

• Bowed legs or knocked knees when walking
• Widened wrists and ankles
• Bumps on the ribs (rachitic rosary)
• Curved spine or a protruding breastbone
• Poor growth and delayed motor milestones like sitting, crawling, walking

Symptoms in older adults

• Rickets itself is rare in older adults, but a related condition called osteomalacia can cause bone pain, muscle weakness, and an increased risk of fractures.

Causes

Main causes

• Lack of vitamin D: not enough sunlight exposure on the skin
• Insufficient calcium or phosphorus in the diet
• Problems with the body's ability to absorb vitamin D or minerals (e.g., certain digestive or kidney diseases)
• Rare genetic disorders that affect how the body processes vitamin D or phosphate

Risk factors

• Living in northern regions with little sunlight, especially in winter
• Having dark skin (which makes less vitamin D from sunlight)
• Spending most of the time indoors or covering the skin completely
• Being exclusively breastfed without vitamin D supplements
• Following a vegan or dairy-free diet without fortified foods
• Certain medical conditions like celiac disease, cystic fibrosis, or kidney disease
• Taking some medicines that lower vitamin D levels (like certain epilepsy treatments)

When to see a doctor

See a doctor urgently if:

• If your child has pain or tenderness in the bones, especially if they are not willing to move a limb
• If you notice any new bone deformities like bowed legs or a curved spine
• If your child has muscle cramps or spasms that are severe or happen often

Book a routine appointment if:

• If you have concerns about your child's growth or development
• If your child's diet is very limited in foods containing vitamin D or calcium
• If your family has a strong history of bone problems or vitamin D deficiency

Diagnosis

A doctor will ask about your child's symptoms, diet, sun exposure, and family history. They will examine the child's bones and muscles for signs of weakness or deformity.

Tests that may be done

• Blood tests to measure levels of vitamin D, calcium, phosphate, and alkaline phosphatase (a bone enzyme)
• X-rays of the wrists, knees, or other bones to look for softening or widening
• Sometimes a bone density test or other imaging to check bone strength

What to expect at your appointment

The doctor will explain what each test looks for. Blood tests may be done at a clinic or hospital, and results usually come back in a few days. X-rays are quick and painless. The doctor will then discuss the findings and recommend a treatment plan that fits your child's needs.

Treatment

Treatment for rickets focuses on correcting the vitamin D and mineral levels in the body. This is usually done with higher doses of vitamin D and calcium, given as supplements. The goal is to make bones stronger and stop further damage.

Self-care at home

• Spending time in sunlight safely (about 10–15 minutes a day on bare skin, without sunscreen, but avoid burning)
• Eating foods rich in vitamin D and calcium, such as fortified milk, oily fish, egg yolks, and green leafy vegetables
• Following the doctor's advice about supplements – never give extra doses without talking to a healthcare professional

Medical treatments

The main medical treatment is vitamin D supplementation. This can be given as a high-dose liquid or tablet, often for several months. Calcium or phosphate supplements may also be needed. In some cases, especially when an underlying condition prevents absorption, regular injections of vitamin D may be given. All treatments are prescribed and monitored by a doctor.

When is surgery considered?

Surgery is rarely needed for rickets. It may be considered if severe bone deformities (like very bowed legs) do not improve with treatment and cause problems with walking or daily life. Surgery can straighten or realign the bones, but this is unusual and only done after careful discussion with a specialist.

Living with this condition

Most children with rickets can live a normal, active life once treatment begins. It is important to follow the doctor's plan, take supplements as directed, and attend follow-up appointments. Bone pain usually improves within a few weeks, and deformities may slowly correct over months or years.

Lifestyle tips

• Get regular, safe sun exposure – aim for short periods without sunscreen, but in moderation and not during peak hours to avoid sunburn
• Ensure the diet includes enough vitamin D and calcium – consider fortified foods or ask a dietitian for advice
• Encourage gentle physical activity like walking or playing to help strengthen bones, but avoid high-impact sports until the doctor says it's safe

Diet and exercise

A balanced diet with plenty of calcium and vitamin D is key for recovery. Include dairy products (or fortified plant milks), oily fish, eggs, and green vegetables. Vitamin D is also added to some breakfast cereals and spreads. Regular exercise helps build bone strength, but start slowly and listen to what your child's body can handle.

Mental health and emotional wellbeing

Dealing with a long-term health condition can be stressful for both the child and the family. If your child feels different because of their appearance or has pain, it may affect their mood or confidence. Open communication, reassurance, and support from school and friends can help. If you notice signs of anxiety or depression, talk to your healthcare provider.

Prevention

Yes, rickets can often be prevented. The most important steps are getting enough sunlight exposure for vitamin D production and eating a diet rich in vitamin D and calcium. In northern climates or for at-risk groups, taking a vitamin D supplement as recommended by a doctor can help prevent deficiency.

Vaccines

There is no vaccine specifically for rickets. However, ensuring children get all routine vaccinations helps protect against infections that could worsen overall health and nutrition.

Screening programmes

There is no routine screening for rickets in the general population. However, if a child has risk factors (like very limited sun exposure, a diet low in vitamin D, or a mother who was deficient during pregnancy), doctors may check vitamin D levels with a blood test.

Complications

If left untreated

• Severe bone deformities that can cause permanent bowing of legs or curvature of the spine
• Frequent bone fractures
• Stunted growth and short height
• Dental problems like delayed tooth formation and cavities
• Muscle weakness that makes daily activities difficult

Long-term outlook

With early diagnosis and proper treatment, most children with rickets recover fully. Bone pain often goes away within a few weeks, and deformities can correct over time as the child grows. In very severe or untreated cases, some bone changes may be permanent, but even then, treatment can prevent further damage and improve quality of life. The key is to act early and follow medical advice. There is every reason for hope.
