Most People were instructed to "drink your milk" as a child if they wanted strong bones. This is because milk is a well-known calcium source, essential for maintaining healthy bones. According to the NIH Osteoporosis and Related Bone Diseases National Resource Center, calcium is necessary for healthy teeth, blood clotting, the proper operation of your heart, muscles, and nerves, and supporting bone growth.
Given that your bones and teeth contain 99% of the calcium in your body, this is not surprising. According to the National Library of Medicine, not receiving enough calcium can cause osteoporosis to develop and dramatically raise the risk of bone fractures as you age.
An overall decline in bone health is a defining symptom of calcium insufficiency. If you don't get enough calcium from your diet, your body will take what it needs from your bones and teeth to keep blood calcium levels healthy. If left untreated, calcium shortage can lead to bone fragility and weakening, significantly raising your risk of fracture and developing osteoporosis.
As we age, our bodies become less capable of absorbing the calcium we consume, and our bones become weaker. More falls, such as those in and out of the shower or while climbing stairs, may result from fragile bones.
A calcium deficiency can cause fatigue. However, this isn't your typical case of exhaustion; the National Library of Medicine describes it as a continuous sense of weakness and low energy.
Hypocalcemia symptoms are more chronic than other mineral deficiencies and less immediately noticeable. You may not notice that you're losing strength or finding it harder to carry out daily duties when you develop a calcium deficit.
Muscle cramps and spasms are apparent symptoms of a calcium shortage. Muscle cramps grow more often (particularly in the back of your lower legs) as symptoms increase, and you may also experience stiff, achy muscles.
According to a 2018 Best Practice & Research Clinical Endocrinology & Metabolism article, calcium is necessary to support muscles' ability to contract and relax. Neurons become unstable and impulsively activate when your muscles lack calcium, which can cause uncomfortable muscle contractions.
