What happens when you have low calcium?

01/10Let’s understand the role of calcium in the body

Calcium is an essential mineral that plays a crucial role in various physiological processes, including bone health, muscle function, nerve transmission, and blood clotting. When calcium levels in the body drop below the optimal range, it can lead to a range of symptoms and health complications. In this article, we will explore the effects of low calcium levels, known as hypocalcemia, on the body and its implications for overall health.

Calcium is primarily stored in bones and teeth, where it provides structural support and strength. However, calcium also plays a vital role in other functions throughout the body:

Bone health: Calcium is essential for maintaining bone density and preventing conditions like osteoporosis and osteopenia.

Muscle contraction: Calcium ions are necessary for muscle contraction and relaxation. Adequate calcium levels ensure proper muscle function, including the contraction of the heart muscle.

Nerve transmission: Calcium ions are involved in transmitting nerve impulses throughout the body. They help regulate the release of neurotransmitters and facilitate communication between nerve cells.

Blood clotting: Calcium is required for the coagulation cascade, a series of biochemical reactions that lead to the formation of blood clots. Without sufficient calcium, blood clotting may be impaired, leading to increased bleeding risk.


02/10​Signs of low calcium in the body​

Low calcium levels, or hypocalcemia, can have significant effects on various physiological processes throughout the body, leading to symptoms such as muscle cramps, tingling, weakness, and bone density loss. When calcium levels in the body drop below the normal range (typically below 8.5 mg/dL), it can result in hypocalcemia, which manifests in various symptoms and health complications:


03/10​Cognitive impairment​

Low calcium levels may affect cognitive function and mental clarity. Calcium ions are involved in neurotransmitter release and synaptic transmission in the brain, and disruptions in calcium homeostasis can impair cognitive processes, memory, and concentration.


04/10​Weakness and fatigue​

Calcium deficiency can lead to feelings of weakness, fatigue, and lethargy. Muscles require adequate calcium to function optimally, and low levels may impair muscle strength and endurance, leading to generalized weakness and reduced energy levels.


05/10​Heart rhythm abnormalities​

Calcium plays a crucial role in regulating heart muscle contraction and maintaining normal heart rhythm. Hypocalcemia can disrupt these processes, potentially leading to heart palpitations, arrhythmias, or even cardiac arrest in severe cases.


06/10​Dental problems​

Calcium deficiency can affect dental health, leading to weakened tooth enamel, tooth decay, and an increased risk of gum disease. Calcium is essential for maintaining strong teeth and supporting oral health, and inadequate intake can compromise dental integrity.


07/10​Bone density loss​

Chronic low calcium levels can compromise bone health and increase the risk of osteoporosis, a condition characterized by decreased bone density and increased fracture risk. Without sufficient calcium, bones may become weak, brittle, and prone to fractures over time.


08/10​Tingling and numbness​

Hypocalcemia can cause tingling sensations, numbness, or a “pins and needles” feeling, especially in the hands, feet, face, and around the mouth. This occurs due to disruptions in nerve transmission, as calcium ions are essential for maintaining proper nerve function.


09/10​Muscle cramps and spasms​

Low calcium levels can lead to muscle cramps, spasms, and stiffness. Calcium ions play a crucial role in muscle contraction and relaxation. When calcium levels are low, muscles may contract involuntarily, resulting in cramping and discomfort, particularly in the legs and hands.
