From Cramps to Cracks: What Calcium Deficiency Is Trying to Tell You
Share
Calcium isn’t just another mineral—it’s the unsung hero behind strong bones, active muscles, sharp nerves, and balanced hormones. From playful toddlers to wise grandmothers, calcium supports us at every stage of life.
But here’s the surprising part: calcium deficiency is far more common than most people realize—especially in women. During key life phases like pregnancy, breastfeeding, and after menopause, the body’s need for calcium spikes, and if it’s not met, it can quietly impact long-term health.
So, why exactly is calcium such a big deal—and why does it become even more important at certain stages of life? Let’s dive in!
Why Calcium is So Important?
Calcium is essential for:
- Building and maintaining strong bones and teeth
- Muscle contraction and relaxation
- Transmission of nerve signals
- Blood clotting and enzyme function
About 99% of calcium in our body is stored in bones and teeth. The rest helps support vital body functions—every single day.
Sources of Calcium
· Direct Calcium Sources
These foods are naturally rich in calcium and should be included in your daily diet:
- Dairy products (milk, yogurt, cheese)
- Leafy green vegetables (kale, bok choy, spinach)
- Tofu and soybeans
- Canned sardines and salmon (with bones)
- Nuts and seeds (almonds, chia, sesame)
-
Fortified foods (plant-based milks, juices, cereals)
· Indirect Calcium Sources
These don’t contain calcium themselves but enhance calcium absorption in the body:
- Vitamin D (sunlight, eggs, fatty fish, fortified foods)
- Magnesium and Vitamin K2 (found in greens, seeds, fermented foods)
- Weight-bearing exercise (helps calcium deposit into bones)
Why Calcium Becomes Insufficient in Women After a Certain Age?
As women age—especially after 40 and post-menopause—oestrogen levels drop. Oestrogen helps in calcium absorption and bone retention. Its decline leads to:
- Reduced calcium absorption
- Faster bone loss
- Increased risk of osteoporosis
That’s why the need of calcium in women aged 50 and above may vary between 1000- 1,200 mg/day compared to 1,000 mg/day for younger adults.
The Role of Calcium During Pregnancy & Lactation
Pregnancy and breastfeeding significantly increase calcium demand:
During Pregnancy:
- Supports foetal bone and teeth development
- Prevents complications like preeclampsia
- Recommended intake: 1,000 mg/day
During Lactation:
- Calcium is lost through breast milk
- If dietary calcium is low, it’s pulled from mother’s bones
- Adequate intake helps maintain maternal bone density
- Recommended intake: 1200 mg/day
Symptoms of Calcium Deficiency
Calcium deficiency often develops slowly. Look out for these signs:
- Frequent muscle cramps or spasms
- Fatigue and mood swings
- Numbness or tingling in fingers and toes
- Brittle nails and tooth decay
- Slow growth and bone development (in children)
- Increased risk of bone fractures
Causes of Calcium Deficiency
Calcium levels can drop due to several factors:
- Inadequate calcium intake from food
- Poor calcium absorption due to digestive issues
- Vitamin D deficiency
- High sodium or caffeine consumption
- Use of medications like steroids or diuretics
- Hormonal changes (especially in menopausal women)
- Kidney disorders or parathyroid problems
Deficiency Disorders Caused by Low Calcium
Low calcium levels, if ignored, can lead to serious health issues:
Osteoporosis
- Bones become brittle and prone to fractures
- Common in postmenopausal women
Rickets (Children)
· Poor bone development leading to bowed legs and skeletal deformities
Osteomalacia (Adults)
- Soft, weak bones causing pain and muscle weakness
Tetany
- A condition marked by severe muscle spasms, cramps, and seizures
How to Overcome Calcium Deficiency
1. Increase Calcium-Rich Foods
Incorporate calcium-rich foods into your daily meals and snacks.
2. Take Supplements (if needed)
Calcium supplements are helpful, especially for older adults or during pregnancy. Choose ones with Vitamin D for better absorption.
3. Boost Vitamin D Intake
Spend time in the sun, eat fortified foods, and consider supplements if necessary.
4. Exercise Regularly
Weight-bearing exercises like walking, jogging, or yoga improve bone health and calcium retention.
5. Limit Caffeine, Soda, and Excess Salt
These can reduce calcium absorption or increase calcium loss through urine.
