hyponatrémiával

Hyponatremia is a medical condition characterized by a lower than normal concentration of sodium in the blood. Sodium is an electrolyte that plays a crucial role in maintaining fluid balance and nerve and muscle function. When sodium levels drop too low, water can move into the body's cells, causing them to swell. This swelling can be particularly dangerous in the brain.

The symptoms of hyponatremia can vary widely depending on the severity and how quickly the sodium levels have dropped. Mild cases may be asymptomatic or present with subtle signs like fatigue, headache, or nausea. As levels decrease further, more severe symptoms can emerge, including confusion, irritability, muscle weakness, seizures, and even coma. In chronic, slow-developing hyponatremia, the body may adapt, and symptoms may be less pronounced.

There are numerous causes for hyponatremia. These can include excessive water intake, which dilutes the sodium concentration in the blood, certain medications like diuretics, hormonal imbalances such as those related to the pituitary or adrenal glands, kidney disease, heart failure, and liver disease, all of which can affect fluid and electrolyte regulation. Conditions causing significant fluid loss through vomiting or diarrhea can also contribute.

Diagnosis of hyponatremia is typically made through a blood test that measures the serum sodium level. The underlying cause of the hyponatremia must then be identified through medical history, physical examination, and further laboratory tests. Treatment focuses on correcting the sodium deficit and addressing the underlying cause. This may involve fluid restriction, adjusting medications, or treating specific medical conditions. In severe or acute cases, intravenous administration of sodium may be necessary, but this must be done carefully to avoid complications.
