Sodium deficiency or hyponatraemia refers to the low sodium concentration in the body of an individual. As other minerals, Sodium also plays essential roles in the human body. It is required for many of the functions of the body, including blood pressure management, fluid balance and the proper functioning of the nervous system. It may also sometimes lead to neurological impairments which affect walking and attention and could also result in bone fracture. Hyponatremia can be caused due to drinking too much of water, without enough replacement of sodium from the body. However, consuming too much of sodium can increase the volume of blood in the body, resulting in various health problems and can sometimes lead a person to coma.
The symptoms of sodium deficiency or hyponatraemia aren’t usually always specific. They can differ from person to person and depend on how rapid the fall in the sodium concentration of the body is. However, some of the common symptoms that are usually seen in the affected persons are as follows:
The severity of these symptoms depends on the speed i.e., on how fast the fall in the blood salt level is. A gradual, low-level drop can be tolerated if it lasts for a few days or weeks, but the deficiency of sodium in the body can be fatal if not treated as early as possible. It may even lead to the death of a person. If you wish to discuss about any specific problem, you can consult a general physician.
