Endocrinologist explains 10 symptoms of lack of calcium in a woman that can’t be ignored

When talking about strong bones, healthy muscles, and over-all wellness, calcium for women is critical. But, unfortunately many of the women suffer from calcium deficiency without their knowledge.

Calcium is one of the most important minerals in the human body, helping to build and maintain strong bones and teeth. In addition to keeping bones healthy, calcium also aids in muscle contractions, nerve signalling, blood clotting and heart function. For women, the need of calcium is further more important as hormonal changes that reduce bone density start from puberty—pregnancy, breast feeding and menopause being the most crucial stages. Yet despite its significance, it is still a common problem in women of all ages.

Inadequate shaking, not enough muscle exercise or regular exercise through activities of daily living — as well as diet and vitamin D level factors — also can contribute to decreased calcium absorption. That shortage can over time quietly weaken the bones and cause fatigue, cramps and other severe outcomes such as osteoporosis. The trouble is early indicators can sometimes be dismissed or blamed on other problems.

Noida-based Endocrinologist and Women’s Health Specialist Dr Reena Awasthi under brand WeCareHealth told Moneycontrol that attending to subtle but persistent signs early on can help prevent irreversible bone loss, and ensure a lifetime of vitality.

Frequent Muscle Cramps and Spasms

One of the first signs of calcium deficiency is muscle cramps or tightness — this commonly occurs in your legs, back and arms. Low levels of calcium can lead to painful muscle spasms or twitching because it is necessary for muscle contraction.

Brittle Nails and Hair Loss

Calcium strengthens keratin, the protein that makes up hair and nails. A lack of it can cause nails to become brittle, and break easily as well as increase hair loss or thinning.

Numbness and Tingling Sensation

When nerve function is impacted, it may cause tingling or numbness in the hands or feet, or around the mouth. Many times these are subtle feelings, but overwhelming the body with sensation is a symptom of an out of balance nervous system.

Fatigue and Weakness

Persistent fatigue and low energy can be a sign of calcium deficiency. Calcium is essential for muscle function and cellular energy production, so not getting enough could lead you to feel weak or sluggish all of the time.

Tooth Decay and Gum Problems

Calcium strengthens teeth and jawbones. And a lack of it may contribute to tooth sensitivity, weak enamel, and increased risk for cavities and gum disease.

Bone and Joint Pain

Chronic back pain or joint ache could be an early sign of decreased bone density. Chronic calcium deficiency can result in weak, fragile bones and put you at risk for fractures and osteoporosis.

Irregular Heartbeat

Calcium is critical in controlling the heart beat. Palpitations or irregular heart rhythm is a symptom that should never be ignored.

Dry Skin and Premature Aging

Elasticity and hydration of the skin is managed by calcium. Its lack can make your skin dry, itchy or hardened and prematurely aged.

Insomnia or Poor Sleep

The brain uses tryptophan to help make melatonin, the hormone that brings on sleep. Low calcium can cause restlessness and poor sleep.
