Rickets: Causes, Risk Factors, Symptoms, Treatment


Rickets is a rare but potentially serious condition that affects bone development in children. It is primarily caused by a deficiency of vitamin D, calcium, or phosphate, which are essential for healthy bone growth. Rickets can lead to soft, weak bones, skeletal deformities, and other health problems if left untreated. When there's a shortage of vitamin D or an inability to absorb it properly, the body struggles to maintain adequate levels of these minerals, leading to weakened, soft, and malformed bones. This condition often manifests through symptoms like bowed legs, delayed growth, bone pain or tenderness, muscle weakness, and skeletal deformities. Rickets can be caused by insufficient sunlight exposure, a lack of dietary intake of vitamin D and calcium, certain medical conditions affecting nutrient absorption, or genetic factors. Treatment typically involves supplementation of vitamin D and sometimes calcium, along with adjustments in diet and increased exposure to sunlight to help restore proper bone development and strength.

Symptoms of Rickets

If you suspect you or someone else is experiencing Rickets, it is crucial to seek immediate medical attention by calling emergency services or consult with a Nutritionist.


Vitamin D Deficiency: The most common cause of rickets is a lack of vitamin D, which is necessary for the body to absorb calcium from the diet. This deficiency can occur due to inadequate dietary intake, lack of sunlight exposure (as sunlight helps the body produce vitamin D), or a problem with the body's ability to process vitamin D. Calcium or Phosphate Deficiency: Rickets can also be caused by insufficient dietary intake of calcium or phosphate. These minerals are crucial for bone development. Genetic Factors: In some cases, rickets can be hereditary, caused by genetic mutations affecting calcium and phosphate regulation in the body. Malabsorption Disorders: Conditions that affect the absorption of nutrients in the digestive tract, such as celiac disease or inflammatory bowel disease, can contribute to rickets.

Risk Factors

Dark skin: People with darker skin produce less vitamin D when exposed to sunlight. Limited sunlight exposure: Insufficient sunlight, especially in regions with limited sunshine or in individuals with limited outdoor activity, can increase the risk. Exclusive breastfeeding: Babies who are exclusively breastfed without vitamin D supplementation are at risk. Premature birth: Premature infants may have lower vitamin D stores. Certain medical conditions: Conditions like celiac disease, kidney disorders, and others can increase the risk. Medications: Some medications can interfere with vitamin D metabolism or calcium absorption.


Common symptoms include bowed legs or knock knees, delayed growth, muscle weakness, and bone pain or tenderness, particularly in the spine, pelvis, and legs. Children with rickets may also exhibit a protruding breastbone, dental problems, and an increased susceptibility to fractures due to weakened bones. In severe cases, this condition can lead to skeletal deformities and impaired motor development. Early detection and appropriate treatment with vitamin D supplementation and dietary adjustments are crucial in managing rickets and preventing long-term complications.

Need an Appointment?


Rickets is a condition primarily diagnosed through a combination of physical examination, medical history review, and laboratory tests. During a physical exam, a healthcare professional may observe signs like skeletal deformities, delayed growth, bowed legs, or a protruding breastbone. A medical history review often involves assessing a patient's diet, exposure to sunlight, and any underlying conditions that could affect calcium, phosphate, or vitamin D metabolism. Laboratory tests such as blood tests to measure levels of calcium, phosphate, alkaline phosphatase, and vitamin D are crucial for confirming the diagnosis. X-rays may also be conducted to evaluate bone density and structure, helping to confirm the presence of rickets and its severity.


Treatment depends on the underlying cause of rickets and may include: Vitamin D and Nutritional Supplements: If the deficiency is due to inadequate intake, supplements of vitamin D, calcium, or phosphate may be prescribed. Sunlight Exposure: In cases of vitamin D deficiency, safe exposure to sunlight can help the body produce vitamin D naturally. Dietary Changes: A diet rich in vitamin D, calcium, and phosphate can be recommended. Treating Underlying Conditions: If rickets is caused by a medical condition or medication, addressing these issues is essential. Orthopedic Interventions: Severe bone deformities may require orthopedic surgeries or bracing.

Preventive Measures

Rickets, a condition primarily caused by vitamin D deficiency, can be prevented through several measures. Adequate exposure to sunlight, which enables the skin to produce vitamin D, is crucial. Encouraging outdoor activities, particularly during early morning or late afternoon when the sun's rays are less harsh, helps in this regard. Additionally, maintaining a balanced diet rich in vitamin D sources like fortified dairy products, fatty fish, eggs, and mushrooms can significantly reduce the risk of rickets. Supplementation, especially in high-risk groups such as infants, individuals with limited sun exposure, or those with specific medical conditions affecting nutrient absorption, is also recommended under medical supervision. Regular check-ups and screening for vitamin D levels can aid in early detection and intervention to prevent the onset of rickets.

Do's & Don’t's

Do's Don't
Ensure adequate sunlight exposure, about 10-30 minutes a day. Avoid excessive sun exposure, especially during peak hours.
Consume foods rich in vitamin D, such as fatty fish, fortified dairy products, and egg yolks. Don't rely solely on sunlight for vitamin D; dietary sources are essential.
Encourage a balanced diet with sufficient calcium-rich foods like dairy, leafy greens, and fortified cereals. Avoid diets lacking in calcium or vitamin D-rich foods.
Consult a healthcare professional for appropriate vitamin D supplements if deficiency is diagnosed. Don't self-prescribe vitamin D supplements without medical advice.
Engage in weight-bearing exercises to promote bone health and development. Avoid sedentary lifestyles or excessive inactivity.
Follow a doctor's recommended treatment plan if diagnosed with rickets. Don't ignore symptoms or delay seeking medical help if suspecting rickets.
Ensure infants receive proper nutrition, including breast milk or formula with vitamin D supplementation. Don't exclusively breastfeed without considering vitamin D supplementation for infants.

If you suspect you or someone else is experiencing Rickets, it is crucial to seek immediate medical attention by calling emergency services or consult with a Nutritionist.

Frequently Asked Questions
Rickets is a rare disease that affects the bones. It occurs when the bones in the body soften and weaken, usually because of an extreme and prolonged deficiency of vitamin D, calcium, or phosphate.
Rickets is primarily caused by a deficiency of vitamin D, calcium, or phosphate. Lack of exposure to sunlight, certain medical conditions, and inadequate dietary intake of these nutrients are common causes.
Rickets can affect anyone, but it is more common in children, particularly those who live in regions with little sunlight, have dark skin, or follow strict vegetarian diets.
Common symptoms include delayed growth, pain or tenderness in the bones (especially the spine, pelvis, and legs), muscle weakness, and deformities in the skeleton such as bowed legs or a curved spine.
Diagnosis involves a combination of medical history, physical examination, blood tests to measure levels of vitamin D, calcium, and phosphorus, as well as imaging studies like X-rays.
Yes, rickets can be prevented by ensuring an adequate intake of vitamin D, calcium, and phosphorus through a balanced diet, exposure to sunlight, and, if necessary, vitamin supplements.
