The human body functions like an intricate symphony, with each organ and system playing a crucial role. Among the many elements that must be in balance is the concentration of sodium in our bloodstream. Sodium, an essential electrolyte, is responsible for maintaining fluid balance, nerve function, and muscle contractions. When this delicate balance is disrupted, a condition known as hyponatremia arises.
What Exactly Is Hyponatremia?
According to Dr Reema Kashiva, a Senior Physician from Noble Hospital, Pune, hyponatremia occurs when the level of sodium in the blood drops below normal. While it may sound contrary, low sodium levels can be just as detrimental to the body as high levels. The body's sodium concentration is tightly regulated by a complex interplay between the kidneys, hormones, and the thirst mechanism. However, various factors can disrupt this equilibrium and lead to hyponatremia.
Causes Of Hyponatremia
Excessive Fluid Intake
One common cause of hyponatremia is excessive fluid intake without proper sodium replenishment. This can occur in athletes who consume large volumes of water during intense physical activities, diluting the sodium concentration in their blood.
Vasopressin
Another potential cause is the inappropriate secretion of antidiuretic hormone (ADH), also known as vasopressin. ADH regulates water retention by the kidneys, and when its release becomes dysregulated, excess water is retained, leading to hyponatremia.

Medical Conditions
Medical conditions and medications can contribute to the development of hyponatremia. Heart failure, liver cirrhosis, kidney diseases, and hormonal imbalances are just a few examples of underlying conditions that may disrupt sodium balance. Furthermore, some medications, such as diuretics, antidepressants, and certain pain relievers, can interfere with the body's ability to maintain proper sodium levels.
Symptoms Of Hypnonatremia
Recognising the symptoms of hyponatremia is crucial for early intervention and treatment. As per Dr Kashiva, people may experience nonspecific symptoms such as:
- Nausea
- Headache
- Fatigue
- Muscle cramps
As the condition worsens, more severe symptoms can arise, including confusion, seizures, and even coma. It is important to note that the severity of symptoms may not always correspond directly with the degree of sodium imbalance, making accurate diagnosis and treatment all the more important.
Diagnosis
Diagnosis of hyponatremia involves a comprehensive evaluation, including a thorough medical history, physical examination, and laboratory tests. Blood tests can measure sodium levels, assess kidney function, and identify any underlying conditions contributing to the electrolyte imbalance. In some cases, additional tests may be necessary to determine the specific cause of hyponatremia.

Treatment
Treatment strategies for hyponatremia depend on the underlying cause, severity of symptoms, and the rate at which sodium levels have declined. Mild cases may be managed through dietary modifications, including reducing fluid intake and increasing sodium consumption. In more severe cases, intravenous fluids with carefully measured sodium concentrations may be administered. However, it is crucial that the correction of sodium levels is done gradually, as rapid correction can lead to a potentially life-threatening condition called osmotic demyelination syndrome.
