Calcium Deficiency & Rickets In Kids: Causes, Symptoms, & Complications
Quick Answer
Calcium deficiency (calcium ki kami) and rickets are preventable conditions, and most Indian children who eat a balanced diet and get some sunlight are NOT at risk. However, certain children - especially those with limited sun exposure, picky eaters, or on restricted diets - may need extra attention. The good news is that with proper nutrition and vitamin D, these conditions are easily preventable and treatable when caught early.
What Causes Calcium Deficiency and Rickets?
Rickets is a bone-softening condition caused by:
1. Vitamin D Deficiency (Most Common in India)
-
Limited sun exposure (staying indoors, covered clothing)
-
Dark skin (needs more sun for vitamin D)
-
Exclusive breastfeeding without vitamin D supplements
-
Living in polluted cities with less sunlight 2. Inadequate Calcium Intake
-
Not drinking enough milk or eating dairy
-
Picky eaters avoiding calcium-rich foods
-
Lactose intolerance without alternatives
-
Very restrictive diets 3. Phosphorus Deficiency (Less common)
-
Usually genetic conditions
-
Kidney problems Age Groups Most at Risk:
| Age | Risk Factors |
|---|---|
| 0-6 months | Exclusively breastfed without vitamin D drops |
| 6-24 months | Not getting enough dairy/calcium foods after weaning |
| 2-5 years | Picky eaters, limited outdoor play |
| Any age | Dark skin, limited sun, vegetarian without planning |

Cheese - 1 slice = ~150mg calcium
-
Buttermilk (chaas) - 1 glass = ~100mg calcium Non-Dairy Sources (For Lactose Intolerant):
-
Ragi (nachni) - 100g = ~344mg calcium (EXCELLENT!)
-
Til/Sesame seeds - 1 tbsp = ~88mg calcium
-
Rajma (kidney beans) - 1 cup cooked = ~60mg calcium

Chana (chickpeas) - 1 cup cooked = ~80mg calcium
-
Methi leaves - 100g = ~395mg calcium
-
Amaranth leaves (chaulai) - 100g = ~215mg calcium
-
Dried figs (anjeer) - 3-4 pieces = ~50mg calcium Daily Calcium Requirements:
| Age | Calcium Needed |
|---|---|
| 0-6 months | 200mg (from breast milk/formula) |
| 7-12 months | 260mg |
| 1-3 years | 700mg |
| 4-8 years | 1000mg |
| 9-18 years | 1300mg |
Vitamin D - The Essential Partner
Calcium cannot be absorbed without adequate Vitamin D!
Natural Sources:
-
Sunlight - 15-20 minutes of morning sun (before 10 AM) on arms and legs, 3-4 times per week
-
Fatty fish (salmon, mackerel)
-
Egg yolks
-
Fortified milk and cereals For Babies:
-
Breastfed babies need 400 IU vitamin D drops daily from birth
-
Formula-fed babies usually get enough from fortified formula
-
Continue supplements until baby drinks 500ml+ fortified milk daily
When to See a Doctor
Seek Immediate Care If:
-
Baby has seizures or muscle spasms (can indicate severe calcium deficiency)
-
Noticeable bone deformities developing
-
Child has difficulty breathing (chest deformity)
-
Fractures from minor falls Schedule an Appointment If:
-
Baby’s soft spot hasn’t closed by 18 months
-
Child’s legs appear bowed or knocked
-
Delayed walking (not walking by 18 months)
-
Excessive sweating on head during sleep
-
Child is significantly shorter than peers
-
Teeth are delayed or appear weak/damaged
-
You’re concerned about dietary calcium intake
Treatment Options
For Mild Deficiency:
-
Dietary changes to increase calcium and vitamin D
-
Vitamin D supplements (dosage as per pediatrician)
-
Increased safe sun exposure
-
Regular monitoring For Moderate to Severe Cases:
-
High-dose vitamin D therapy (stoss therapy)
-
Calcium supplements
-
Regular blood tests to monitor levels
-
X-rays to track bone healing For Bone Deformities:
-
Most mild deformities correct with treatment over 1-2 years
-
Severe cases may need bracing
-
Very rarely, surgery for extreme cases
Prevention Tips for Indian Parents
Daily Habits:
-
Include 2-3 servings of dairy OR calcium-rich alternatives daily
-
Morning sunlight exposure (15-20 minutes, 3-4 times/week)
-
Give vitamin D drops to breastfed babies
-
Include ragi, til, and green leafy vegetables in diet
-
Avoid excess phytates (found in unsoaked grains) that block calcium Smart Food Combinations:
-
Ragi porridge with milk = double calcium boost
-
Til/sesame ladoo for snacks
-
Palak paneer = calcium + iron
-
Curd rice = easy calcium
-
Nachni dosa = calcium-rich alternative What to Avoid:
-
Excessive salt (causes calcium loss)
-
Too many soft drinks (phosphoric acid affects calcium)
-
Overuse of antacids
-
Complete dairy avoidance without alternatives

FAQs
Q: Mera baccha doodh nahi peeta - will he get rickets?
A: Not necessarily! While milk is the easiest calcium source, many non-dairy foods are calcium-rich too. Focus on ragi (nachni) which has more calcium than milk, along with paneer, curd, til, and green leafy vegetables. You can also try flavored milk, curd-based drinks, or cheese if plain milk is rejected. Discuss vitamin D supplementation with your pediatrician.
Q: My baby is 4 months old and exclusively breastfed - should I worry about rickets?
A: Breast milk is perfect nutrition, but it’s low in vitamin D. All breastfed babies in India should receive 400 IU of vitamin D drops daily from birth until they’re drinking fortified milk. This simple step prevents rickets completely. Ask your pediatrician about vitamin D supplements.
Q: Baby ki tangdi mudi hui hai (bowed legs) - is this rickets?
A: Mild bowing of legs is NORMAL in babies and toddlers up to age 2-3 years - this is called physiological bowing and corrects on its own. However, if bowing is severe, gets worse instead of better after age 2, or affects only one leg, consult your pediatrician. They can check vitamin D and calcium levels with a simple blood test.
Q: How much sun exposure does my child need?
A: In India, 15-20 minutes of morning sun (before 10 AM) on the face, arms, and legs, 3-4 times per week is usually sufficient. Darker-skinned children may need slightly more. Avoid harsh afternoon sun which can cause sunburn. Even playing outdoors in the shade provides some vitamin D exposure.
Q: Can vegetarian children get enough calcium without milk?
A: Yes! Ragi (finger millet) actually has MORE calcium than milk. Other excellent vegetarian sources include sesame seeds (til), paneer, curd, tofu, almonds, and dark green leafy vegetables like amaranth and methi. A well-planned vegetarian diet with these foods can easily meet calcium needs.
Q: My child has rickets - will the bone damage be permanent?
A: When caught early and treated properly, most children recover completely with no permanent damage. Bones can heal and straighten with adequate vitamin D and calcium. Even mild to moderate bowing usually corrects fully. Only very severe, untreated cases may have lasting effects - which is why early treatment is important.
