What is one major consequence of hyponatremia?

One major consequence of hyponatremia is altered neuronal function. Hyponatremia refers to low levels of sodium in the blood, which is crucial for the normal function of neurons. Sodium plays a vital role in generating and propagating action potentials, which are essential for the communication between nerve cells. When sodium levels fall, it can lead to changes in osmotic balance, causing the movement of water into neurons. This influx of water can result in cellular swelling, disrupting neuronal signaling and leading to neurological symptoms such as confusion, seizures, or even coma. Consequently, altered neuronal function can manifest as varying degrees of cognitive disturbances, motor dysfunction, or altered consciousness, illustrating the significant impact of sodium imbalances on nervous system health.
