The medical term used to refer to calcium deficiency is hypocalcemia, and it refers to low levels of calcium in the blood. Calcium deficiency over a long period of time can lead to other conditions like cataract, osteoporosis, dental issues, and alterations in the brain. It can also lead to the bones becoming brittle easily. Some of the complications of calcium deficiency can be life-threatening as well, and failure to treat the deficiency can even lead to a fatality in extreme cases.

Calcium deficiency does not easily manifest early symptoms, which means it is difficult to detect. Some of the best ways to avoid any form of complications are to undergo regular diagnosis and seek out treatment in case any of the major symptoms of calcium deficiency manifest. These symptoms are usually progressive in nature:

• Muscle problems
  One of the most commonly occurring and earliest signs of calcium deficiency are muscle aches, spasms, and cramps. The individual usually experiences pain in the thighs and arms. The pain is, in particular, under the arms during any form of movement like even walking. There can also be signs of a tingling sensation in various parts of the arms and legs and even around the mouth sometimes.
• Extreme levels of fatigue
  People suffering from calcium deficiency tend to feel extreme levels of lethargy and fatigue, and the body feels sluggish with a complete lack of energy. This deficiency may also lead to insomnia. Some of the forms of fatigue that are associated with this condition are dizziness, lightheadedness, and even brain fog that could probably manifest as forgetfulness, confusion, and lack of focus.
• Bone-related conditions
  Osteopenia and osteoporosis are direct results of a calcium deficiency. The former is a condition wherein the individual loses bone mass and the bones grow weak, leading to an increased risk of fractures. The mineral density of the bone is compromised, and the condition worsens with time, increasing one’s risk of developing osteoporosis. Given that bone density degradation is a progressive disorder, calcium deficiency is also bound to cause issues with the passing of time.
• Symptoms affecting the nails and skin
  When an individual has a chronic calcium deficiency, the skin could become dry and itchy, and research shows how eczema (a form of inflammation on the skin) and psoriasis are often markers of calcium deficiency. In the same way, the nails can also become dry. This deficiency can also lead to the onset of a condition called alopecia, which causes the falling out of hair in round patches.

Some other symptoms that have been frequently associated with calcium deficiency are painful premenstrual syndrome (PMS), dental problems, and depression. If one experiences any of these symptoms, it is better to consult a doctor and undergo a thorough diagnosis in order to know the underlying cause of the symptoms and prevent their progression.
