Hyponatremia is a dangerous condition caused by low sodium levels in the body, often due to excessive water intake or sweating. Symptoms include vomiting, nausea, and headaches, and can lead to seizures or coma. Treatment involves electrolyte replacement and identifying the root cause. Athletes are at increased risk and should consume electrolytes with water.
Hyponatremia is a medical term that refers to a dangerously low level of sodium in the body. Sodium, along with other electrolytes, is a crucial mineral in the human diet that helps transport water throughout the body and helps regulate nerves and major organs such as the heart. When a human body experiences hyponatremia, the results can be fatal if the condition is not promptly addressed. Some people are more at risk for this condition than others, and in all cases the prognosis is better if the problem is identified early.
Fortunately, true hyponatremia is very rare. There are a number of causes for the condition, though the most commonly known is water intoxication. Water intoxication occurs when someone consumes an excessive amount of water, severely diluting the electrolyte concentration in the blood. The condition can also occur when someone sweats excessively, losing a large amount of electrolytes, or in elderly patients who cannot regulate their internal electrolyte balance as well. Because it has numerous causes, the condition can sometimes indicate a medical problem that needs to be treated.
Early signs of hyponatremia include vomiting, nausea, headache, and a general feeling of being unwell. If the condition is not identified and treated, the patient’s condition will worsen and they may experience seizures, a state of stupor or, in extreme cases, coma. Because symptoms are vague, clinicians should be alert to patients who appear to have an impaired level of consciousness and are at risk. If you experience symptoms and have been drinking a lot of water or exercising heavily, you should notify your doctor.
To correct hyponatremia, a doctor will give electrolytes intravenously or have the patient take them by mouth. If caught early, the condition can be treated fairly easily, but in more extreme cases the prognosis is more uncertain. Once the patient has stabilized, it is important to identify the root cause of the condition to ensure the condition does not recur and to treat any underlying medical conditions.
High-performance athletes are at increased risk for hyponatremia, as they train hard, lose electrolytes through sweat, and drink lots of water to stay hydrated. To prevent the condition, athletes should always consume electrolytes with their water and should be aware of their physical limitations. Athletic coaches should keep a close eye on the men and women under their care for early warning signs and address them.
