5. Neurological alterations
Following the same logic as the two previous points, low calcium levels will negatively affect our brain function, but also our nerves, which are also made of long neurons that are anatomically and functionally connected with each other. Some symptoms in our body are actually caused by our nervous system not working well.
For example, one of the most common symptoms of moderate to severe calcium deficiency is a sensation of tingling or numbness in our distal limbs (such as our fingers and toes) and our mouth. Other neurological effects might include seizures, which are caused by a decreased capability of our own brain to regulate and inhibit our own neurological impulses inside our encephalitis.
Also, low calcium might rise our intracranial pressure, which means that the liquid in which our brain is floating can press our head and brain from the inside, causing headaches and other problems.
