Sodium is an important electrolyte in the body that helps keep the equilibrium of fluids, nerves, and muscles. Hyponatraemia is a disorder in which salt levels decline. This can cause a range of health problems, from moderate ones like weariness to serious ones like seizures and coma. Keeping your salt levels in the right range is very important for your health. This article talks about the reasons, signs, and many ways—both medical and at home—to get salt levels back to normal and keep them there.
When the amount of sodium in the blood drops below 135 milliequivalents per litre (mEq/L), it is called hyponatraemia. Sodium is necessary for keeping the right amount of fluid in the body and for cells to work properly. When you have hyponatraemia, too much water in your body lowers the sodium levels, which can cause these functions to stop working and lead to serious health problems.

To avoid hyponatraemia, especially if you are more susceptible to acquiring it:
Hyponatraemia can be anything from a small problem to a life-threatening condition. To manage and avoid low sodium levels, it's important to know what causes them, be able to spot the signs, and act quickly. To be healthy, you need to keep your salt levels in check. You can do this by changing your diet, using home remedies, or getting medical care. Always talk to a doctor or other healthcare professional about the best method to meet your needs.
