Hyponatremia (Definition)

Normal sodium range from 135 to 145. Low sodium (hyponatremia) is less than 135. Some may have no symptoms at slight decrease in sodium level especially if the level dropped slowly. Rapid decrease or large drop in levels can cause confusion, seizures, coma and even death. Labs should always be rechecked to ...Read more

What is clinically-induced hyponatremia?

What is clinically-induced hyponatremia?

Please clarify: Hi. We do not induce hyponatremia, we treat it. I don't know what you mean by "clinically-induced" hyponatremia. The causes of hyponatremia, and the approach to treating it, depend on whether the circulating blood volume is low, normal, or high. Please clarify your situation with a little information (volume status, heart status, cancer, etc). Good luck! ...Read more

Is it possible to get hyponatremia from dehydration?

Is it possible to get hyponatremia from dehydration?

Definitely: Hyponatremia means you have a low sodium level. One way is through dehydration. Dehydration causes hyponatremia usually when a patient is taking a diuretic like hctz (hydrochlorothiazide) or lasix. In this situation, a patient urinates out much more sodium than water. Once this excess sodium is released and the patient's bloodwork is check, there will be much more water than sodium and the pt has hyponatremia. ...Read more

What are the effects of hypernatremia and hyponatremia?

What are the effects of hypernatremia and hyponatremia?

Big topic: Hi. For hypernatremia (hi Na) the body is always hypovolemic and dehydrated. This can result in organ hypoperfusion and tissue damage. For hyponatremia (lo Na), volume status could be low, normal, or high, and needs to be assessed. Lo Na should not be completely normalized rapidly because of possible brain damage due to osmotic shifts (the pons is a classically described site). Need more room! ;-) ...Read more

Can you explain hyponatremia?

Can you explain  hyponatremia?

Low Sodium in Blood: Although the term hyponatremia means "low sodium in blood", it is caused by abnormal handling of water by the kidneys. Reabsorption of water in the kidneys rely on a hormone called ADH (vasopressin) produced in the brain and there are instances where a high concentration is secreted either appropriately (e.g. severe volume contraction) or inapproprately (e.g. medication causing SIADH (vasopressin)). ...Read more

Whats exertional hyponatremia?

Whats exertional hyponatremia?

Excess water: Exertional hyponatremia generally occurs when a person loses excessive amounts of both water and electrolytes (usually through profuse sweating during heavy exercise or warm temperatures). Instead of replacing both, the individual only replaces the water component resulting in relatively excess water in the body. This may result in impairment in brain function due to changes in brain cells. ...Read more

How do you manage hyponatremia?

How do you manage hyponatremia?

Depends: Hi. Hyponatremia (lo Na) can be seen with normal, low, or high circulating blood volume. How it is treated depends on the clinical setting (blood loss/hypovolemia, congestive heart failure, normal blood vol.). If you can specify (e.g., CHF, SIADH, etc), we could be of greater assistance. The standard for SIADH is fluid restriction (sucks) or more recently, a vaptan drug. Good luck. ...Read more

Hyponatremia time: Hyponatremia (H) lasts as long as it is not treated. If one has H due to sodium (S) loss due to diuretics, unless the diuretics are stopped and more S is given to the patient, the S will not improve. If the H gets worse, then the patient may have a seizure and/or die. H can be a serious illness is therapy is started early and appropriately. ...Read more

How about the use of tolvapta in hyponatremia?

Tolvaptan: Tolvaptan can be used in treating euvolemic or hypervolemic hyponatremia and it may provide some benefit in that fluid restriction can be eased. However, the high cost and the concern for liver toxicity limit its widespread use. Also it should not be used for more than 30 days to minimize the risk of liver toxicity. ...Read more
