Sodium (Na)

*Sodium is an essential electrolyte in the body, playing a key role in maintaining fluid balance, nerve transmission, and muscle function. While adequate sodium is vital for health, excessive intake can lead to health problems like high blood pressure.

*Normal Range
Blood Sodium: 136-145 mEq/L

*Risks of Excess Sodium
-High Blood Pressure:
Excess sodium can retain water in the body, increasing heart workload and raising blood pressure.
-Kidney Strain:
High sodium intake can impair kidney function and heighten the risk of kidney disease.
-Dehydration:
Elevated sodium levels may disrupt fluid balance, leading to dehydration.

*Risks of Low Sodium
-Hyponatremia:
Low sodium can cause symptoms like headache, nausea, confusion, and in severe cases, life-threatening conditions.

*How to Maintain Normal Sodium Levels?
-Limit Sodium Intake:
Reduce consumption of processed foods, canned goods, and high-salt items.
-Adopt a Healthy Diet:
Increase intake of potassium- and calcium-rich foods (e.g., vegetables, fruits, whole grains) to support electrolyte balance.
-Stay Hydrated:
Ensure adequate water intake to maintain proper fluid balance.

*Conclusion
Sodium is a vital electrolyte for body function, but its levels must be carefully regulated. Excess or deficiency can lead to health risks. By controlling sodium intake, staying hydrated, and following a balanced diet, you can support cardiovascular and kidney health effectively.
