• #1 Hyponatremia – Symptoms and causes – Mayo Clinic

  https://www.mayoclinic.org/diseases-conditions/hyponatremia/symptoms-causes/syc-20373711

  The following measures may help you prevent hyponatremia: […] Treat associated conditions. Getting treatment for conditions that contribute to hyponatremia, such as adrenal gland insufficiency, can help prevent low blood sodium. […] Educate yourself. If you have a medical condition that increases your risk of hyponatremia or you take diuretic medications, be aware of the signs and symptoms of low blood sodium. Always talk with your doctor about the risks of a new medication. […] Take precautions during high-intensity activities. Athletes should drink only as much fluid as they lose due to sweating during a race. Thirst is generally a good guide to how much water or other fluids you need. […] Consider drinking sports beverages during demanding activities. Ask your doctor about replacing water with sports beverages that contain electrolytes when participating in endurance events such as marathons, triathlons and other demanding activities.

  Hyponatremia is sometimes merely a laboratory artifact or a result of improper blood collection. If real, it can be due to excessive water intake or, most often, the inability of the kidney to excrete water coupled with continued water intake. Patients with significant underlying cardiac, hepatic, or renal dysfunction are at greatest risk of developing hyponatremia, secondary to the nonosmotic release of antidiuretic hormone (ADH). Others at risk include postoperative patients (especially menstruating women), older patients on thiazide diuretics, patients with malignant or psychiatric illness, and endurance athletes. […] In this article, we review the treatment of acute and chronic hyponatremia, emphasizing the importance of basing the therapy on the severity of symptoms and taking care not to raise the serum sodium level too rapidly, which can cause neurologic dysfunction.

  Hyponatremia or a low blood sodium level can sometimes be corrected before it causes complications. The condition can also be prevented altogether by following certain preventive measures. Some examples of measures that can be taken to correct or prevent hyponatremia as well as points to consider when treating patients are listed below: […] If intravenous sodium solution is prescribed to rise the blood sodium level, care must be taken not to administer too much of the solution too quickly. […] The use of hypotonic fluids such as 5% glucose or sodium chloride 0.18% with glucose 4% and sodium chloride 0.45% should be routinely checked to avoid any risk of dilutional hyponatremia developing. […] Fluid balance charts should be maintained regularly and accurately to detect hyponatremia and fluid overload.

• #7 Azthena logo with the word Azthena

  Associated conditions such as adrenal gland insufficiency should be treated appropriately and adequately to avoid hyponatremia. […] Healthcare staff should be aware of the hyponatremia risk associated with the use of certain medications such as diuretics. […] Athletes should closely monitor their water intake. Athletes should drink enough fluid to replace the fluid lost during training but should also be careful not to drink so much fluid that they increase their risk for hyponatremia. […] For heavy training sessions, drinks containing electrolytes may be preferred to replenish the sodium and reduce the risk of hyponatremia. […] Indicators that can help judge a patients water intake include their thirst level and the color of their urine. If they are not thirsty and their urine is pale yellow in color, they are well hydrated and the water intake has been adequate.

• #8 Exercise-Associated Hyponatremia: Prevention and Treatment Recommendations – Endocrinology Advisor

  https://www.endocrinologyadvisor.com/features/exercise-associated-hyponatremia-prevention-and-treatment-recommendations/

  Hyponatremia, defined as sodium levels lower than 135 mmol/L, developing during or 24 hours after exercise is referred to as exercise-associated hyponatremia (EAH). […] The best preventative strategy is to advise people to drink according to physiologically regulated individualized thirst during exercise. […] Risk factors for the development of EAH include duration of exercise of more than 4 hours, slower pace, inexperience, inadequate training and overconsumption of water or hypotonic beverages.

  https://www.germanjournalsportsmedicine.com/archive/archive-2018/issue-10/exercise-associated-hyponatremia-practical-guide-to-its-recognition-treatment-and-avoidance-during-prolonged-exercise/

  Prevention: Proper hydration strategies like drinking limited to thirst can generally prevent EAH. Education of athletes and coaches about EAH is key in preventing this condition. Education of medical staff should focus on early recognition and appropriate treatment of EAH. […] There is now overwhelming evidence that drinking to thirst is adequate to maintain proper hydration during endurance exercise and EAH can be prevented through such hydration strategies. […] Despite widespread advice regarding the acute dangers of dehydration, even in extreme environments, this is of limited relevance to individuals with access to food and water. […] On the contrary, an overzealous approach in fluid ingestion in an effort to prevent dehydration, even in warm humid conditions, has led to reported cases of EAH.

• #10 Hyponatremia | Korey Stringer Institute

  https://koreystringer.institute.uconn.edu/hyponatremia/

  Hyponatremia is mainly caused by hyperhydration, but can also be caused by intake of hypotonic fluids (including sport drinks) that exceed sweat and urine output, excessive sodium losses, or other hormonal dysfunctions that affect the maintenance of sodium stores in the body. […] Understand that universal guidelines are not realistic due to the following factors: Variation in individual sweat rate, Variation in individual sweat sodium concentration, Environmental conditions. […] Have appropriate personnel to educate athletes and staff on fluid balance. […] Educate athletes that hyperhydration does not improve performance and both hyponatremia and hypohydration is associated with performance decrements. […] Consume adequate dietary sodium. […] Allow 8-14 days of training in the heat for acclimatization.

  Hyponatremia hit the headlines with the publication of data on the prevalence of the condition in Ironman finishers. Scarily, over 10% of athletes tested had hyponatremia! […] But what is this potentially race-ruining condition and how can it be avoided? […] In theory, avoiding hyponatremia is pretty straightforward, you just have to avoid drinking more than you sweat and pee out, so that dilution of your blood does not occur. […] For quite a while some experts (notably Prof Tim Noakes, with many others following his lead) have been advocating a drink water to thirst approach for this very reason. […] When healthy people drink water purely to the dictates of thirst during exercise, it has been demonstrated time and again that they dont tend to take in more than they sweat out and, as a result, become gradually dehydrated, making hyponatremia all but impossible.

  Body mass gain during exercise is unnecessary. Its observation is a clear indication of overhydration and when observed, further fluid intake should be reduced to help avoid the development of EAH. […] Education about proper hydration is important in preventing EAH. […] It is therefore paramount that athletes, coaches and health professionals are aware of proper hydration strategies in endurance events and help promote safe hydration guidance.

• #14 RacingThePlanet – Hyponatremia (low Sodium) In Runners

  https://www.racingtheplanet.com/hyponatremia-low-sodium-in-runners

  Hyponatremia (low sodium levels in the blood) has increasingly been recognized as a potentially serious complication of prolonged exercise, especially in ultradistance sports. […] Avoid aggressive water-only hydration practices such as „do not wait until you’re thirsty to drink” and advice like „drink until your urine is clear” based on misguided fears of dehydration. Some research studies predict that long distance triathletes should lose about 4% of body mass during the race in order to maintain a normal blood sodium concentration. Ultradistance athletes should use a combination of water and electrolyte replacement (sports drinks or adding electrolyte powder to water) in order to achieve an appropriate balance of fluids and electrolytes during and after the race and to avoid fluid overload (dilutional) hyponatremia. Athletes should monitor their weight before and after training sessions as a guide to appropriate fluid consumption, with the goal to avoid weight gain.

• #15 Hyponatremia (Low Sodium) Treatment, Causes, Symptoms

  https://www.emedicinehealth.com/hyponatremia_low_sodium/article_em.htm

  How Do I Prevent Hyponatremia? […] Studies have suggested that long-distance runners develop hyponatremia not infrequently after prolonged exercise and should drink adequate amounts of fluid to match their thirst requirements as well as replace sodium along with water during prolonged or extreme exercise. Ideally, a person should not lose more than 2% of their body weight during exercise in order to prevent dehydration and electrolyte abnormalities. […] People who exercise and consume too much water, on the other hand, are at risk for water intoxication and low blood sodium levels. One should take care not to gain weight due to water consumption during exercise. […] Infants should not be fed plain water because their kidneys are not able to adequately concentrate urine, leading to hyponatremia and other electrolyte disturbances.

[…] Monitor the duration and intensity of exercise for determining risk of hyponatremia. […] Supplement water with electrolyte beverages, especially if exercise is lasting longer than 1 hour. […] Record body weight after exercise to monitor fluid losses/consumption. […] Physically active individuals should not consume fluid amounts that exceed the amount of exercise-related body mass lost. […] Return to full activity should follow a graded exercise protocol similar to what would be done during a period of exercise/heat acclimatization.

  It also ignores the valuable contribution of supplementing fluid intake with additional sodium to help aid fluid retention, maintain blood sodium levels and replace some of that lost in sweat. […] Sodium is a finite resource in the body and, as a result, supplementation can help to maintain both blood volume and blood sodium levels much better than drinking water alone, especially at times when sweat losses are high. […] Personalising your sodium and fluid intake not only reduces the risk of hyponatremia, but maximise your performance when sweat losses are high.

  Prevention strategies of hyponatremia in the elderly […] Clinicians should prescribe drugs with caution in elderly patients, especially in those with risk factors to develop SIAD. The avoidance of polypharmacy, especially with drugs implicated in the development of hyponatremia, should be a priority in elderly people. Additionally, the use of low doses of suspected drugs or alternative therapies may be preferable in many cases. For example, low doses of thiazide diuretics (equivalent to 12.5 mg of hydrochlorothiazide) should be prescribed in high-risk patients for hyponatremia or alternative antihypertensive treatment not associated with hyponatremia (eg, a calcium-channel blocker or beta-blockers) should be selected. In fact, a population-based study (n=13,325 individuals, age 45 years old), thiazide diuretic exposure was associated with an almost 5 times higher risk of hyponatremia than nonexposure (hazard ratio [HR] 4.95, 95% CI 4.125.96). Moreover, exposure with an equal or greater than 1 standardized defined daily thiazide dose was associated with a significantly higher risk of hyponatremia than exposure below 1 standardized defined daily thiazide dose (HR 5.72 [95% CI 4.677.00] and 3.42 [95% CI 2.464.77], respectively).

Patients with significant underlying cardiac, hepatic, or renal dysfunction are at greatest risk of developing hyponatremia, secondary to the nonosmotic release of antidiuretic hormone (ADH). Others at risk include postoperative patients (especially menstruating women), older patients on thiazide diuretics, patients with malignant or psychiatric illness, and endurance athletes. […] In this article, we review the treatment of acute and chronic hyponatremia, emphasizing the importance of basing the therapy on the severity of symptoms and taking care not to raise the serum sodium level too rapidly, which can cause neurologic dysfunction.

  Prevention strategies of hyponatremia in the elderly […] Clinicians should prescribe drugs with caution in elderly patients, especially in those with risk factors to develop SIAD. The avoidance of polypharmacy, especially with drugs implicated in the development of hyponatremia, should be a priority in elderly people. Additionally, the use of low doses of suspected drugs or alternative therapies may be preferable in many cases. For example, low doses of thiazide diuretics (equivalent to 12.5 mg of hydrochlorothiazide) should be prescribed in high-risk patients for hyponatremia or alternative antihypertensive treatment not associated with hyponatremia (eg, a calcium-channel blocker or beta-blockers) should be selected. In fact, a population-based study (n=13,325 individuals, age 45 years old), thiazide diuretic exposure was associated with an almost 5 times higher risk of hyponatremia than nonexposure (hazard ratio [HR] 4.95, 95% CI 4.125.96). Moreover, exposure with an equal or greater than 1 standardized defined daily thiazide dose was associated with a significantly higher risk of hyponatremia than exposure below 1 standardized defined daily thiazide dose (HR 5.72 [95% CI 4.677.00] and 3.42 [95% CI 2.464.77], respectively).

  In patients at risk for or with a history of antidepressant-induced hyponatremia, bupropion may be the most appropriate antidepressant treatment. Mirtazapine could be also used alternatively because the associated risk of hyponatremia is moderate. […] Generally, discontinuation of treatment with agents implicated in the development of hyponatremia and avoidance of readministration is fully warranted. However, given that chronic hyponatremia is frequently multifactorial in the elderly, there is increased risk of unnecessary discontinuation of treatments, especially if patients have responded favorably to therapy (eg, a patient on antidepressants with well-controlled symptoms). In such cases, the discontinuation of the most recent suspected medication(s) is a useful strategy. […] The administration of hypotonic fluids as maintenance therapy, for the avoidance of volume overload, is common clinical practice in hospitalized elderly patients. However, this procedure, especially in cases accompanied by elevated antidiuretic hormone (ADH) levels (eg, central nervous system disturbances, pulmonary disease, cancer), may lead to hyponatremia and should be avoided. It has been proposed that isotonic fluids are the most suitable maintenance fluid in most circumstances including compensated heart failure.

  The syndrome of inappropriate antidiuretic hormone secretion (SIADH) is the most frequent cause of hyponatremia in a hospital setting. However, detailed protocols and algorithms for its management are lacking. Our objective was to develop 2 consensus algorithms for the therapy of hyponatremia due to SIADH in hospitalized patients. […] Two algorithms were developed. Algorithm 1 addresses acute correction of hyponatremia posing as a medical emergency, and is applicable to both severe euvolemic and hypovolemic hyponatremia. […] Algorithm 2 is directed to the therapy of SIADH-induced mild or moderate, non-acute hyponatremia. It addresses when and how to use fluid restriction, solute, furosemide, and tolvaptan to achieve eunatremia in patients with SIADH. […] We have elaborated two complementary strategies to treat SIADH-induced hyponatremia in an attempt to increase awareness of its importance, simplify its therapy, and improve prognosis.

  The proper correction rate of serum sodium levels in patients with hyponatremia is of great importance. Overcorrection of serum sodium concentration may lead to the osmotic demyelination syndrome (ODS), especially in alcoholic individuals and patients with hypokalemia, malnutrition or advanced liver disease. In cases of acute symptomatic hyponatremia, an acute elevation of serum sodium concentration by 46 mEq/L within the first 46 h is recommended in order to reverse the symptoms. In chronic hyponatremia, even symptomatic, the rate of the correction of serum sodium concentration should be restricted at 10 mEq/L/24 h and more safely at 68 mEq/L/24 h. Frequent determination of serum sodium concentration (every 46 h) and appropriate tailoring of the correction rate is strongly recommended in patients with high risk of developing the ODS. A number of formulas can be used to predict the change of serum sodium levels during treatment and to calculate the initial infusion rates. Special attention is needed in patients with hypovolemic hyponatremia for a rapid increase in serum sodium levels when volume depletion is restored because of the abrupt decrease in ADH secretion.

  https://www.kidneynews.org/view/journals/kidney-news/15/8/article-p21_14.xml

  Severe hyponatremia (sodium [Na] 120 mmol) can result in hyponatremic encephalopathy requiring emergent treatment with hypertonic saline to prevent death or permanent neurologic impairment. […] The optimal rate and limits for the correction of hyponatremia are uncertain. US and European clinical practice guidelines in 2013 and 2014, respectively, recommend limits of correction of between 8 and 10 mmol/L/24 hours, with re-lowering of the serum Na with free water or desmopressin if these limits are exceeded, for the prevention of ODS. […] Evidence now demonstrates that rapid correction is associated with improved patient outcomes and that ODS is rare and related to risk factors in particular, alcohol use and not to rapid correction. The current treatment guidelines are overly restrictive and could be contributing to worse patient outcomes with increased mortality and length of stay. Hyponatremia treatment guidelines should be revised in favor of a single, 48-hour limit of 15-20 mmol/L, which would simplify treatment, allow for more active treatment with rapid intermittent bolus with hypertonic saline, and decrease the use of desmopressin to control correction, all without producing ODS.

  The strongest case for relowering the serum sodium to prevent osmotic demyelination can be made in patients at very high risk of developing the disorder (those with a sodium 105 mmol/L or patients with heavy alcohol use, severe hypokalemia, malnutrition, or advanced liver disease). […] The cost of limiting correction (more frequent blood draws and perhaps a somewhat longer hospitalization) is trivial when compared with the devastating consequences that can affect even surviving patients with osmotic demyelination syndrome.
