How is thiazide induced hyponatremia treated?

How is thiazide induced hyponatremia treated?

Treatment consists of discontinuing thiazides, regular diet (usually supplemented with K+) restricting water, administration of furosemide and either isotonic saline or, if the hyponatremia is severe or symptomatic, hypertonic saline.

Can thiazides cause hyponatremia?

Hyponatremia is an occasional but potentially fatal complication of diuretic therapy. Virtually all cases of severe diuretic-induced hyponatremia have been due to a thiazide-type diuretic [1-7].

Which type of diuretic may cause hyponatremia?

Thiazide diuretics are more likely than loop diuretics to cause hyponatremia. Loop diuretics inhibit sodium (Na+) transport in the renal medulla and prevent the generation of a maximal osmotic gradient. Thus, urinary concentrating ability is impaired with loop diuretics.

How does HCTZ affect sodium?

With HCTZ, especially at the higher 50-mg dose and especially in the elderly, the kidney is unable to get rid of all the free water we drink, and the sodium in the urine can exceed the sodium in blood, leading to a lowering of the blood sodium level.

Is Lasix a Thiazide?

What Is Lasix? Lasix (thiazides) is an anthranilic acid derivative that is used as a strong diuretic in adults and children to treat excessive fluid accumulation (edema) caused by congestive heart failure, liver failure, renal failure, and nephritic syndrome.

How does Thiazide affect urine volume?

Thiazides increase urine output by inhibiting the NaCl cotransporter on the luminal membrane of the earliest portion of the distal convoluted tubule, often called the cortical diluting segment (Fig. 9-5).

Does Thiazide cause hypokalemia?

Hyperglycemia. Thiazide diuretics cause hypokalemia; at the level of the pancreatic B cells, this hypokalemia causes hyperpolarization of the B cell and decreases insulin secretion. Decreased K in the interstitium keeps the K channels open for an extended time, which causes the hyperpolarization of the cell.

Does bumetanide cause hyponatremia?

Chronic furosemide use typically results in hyponatremia. Furosemide and, to a lesser extent, bumetanide can cause deafness. This risk is greatest in patients with renal impairment who are receiving high doses of furosemide, by either infusion or rapidly administered intravenous bolus doses.

Does hydrochlorothiazide cause low blood sodium?

Answer • The diuretic hydrochlorothiazide is a common cause of low sodium levels.

Does thiazide cause hypokalemia?

What medications can cause hyponatremia?

Certain drugs. Medications that increase your risk of hyponatremia include thiazide diuretics as well as some antidepressants and pain medications. In addition, the recreational drug Ecstasy has been linked to fatal cases of hyponatremia. Conditions that decrease your body’s water excretion.

Which diuretic causes more hyponatremia?

Thiazide diuretics are more likely than loop diuretics to cause hyponatremia. Loop diuretics inhibit sodium (Na+) transport in the renal medulla and prevent the generation of a maximal osmotic gradient. However, diuretic-related hyponatremia can occur on a delayed basis even after several years of therapy.

How does HCTZ cause hyponatremia?

Incidence Not Known. Abdominal or stomach pain. back, leg, or stomach pains. black, tarry stools. bleeding gums. blistering, peeling, or loosening of the skin. bloating. blood in the urine or stools.

How do Thiazides cause hyperlipidemia?

Hyperlipidemia is prevalent in hypertension, but the cause of this association is unknown. Treatment of hypertension with thiazide diuretics accentuates the hyperlipidemia, perhaps by causing potassium or sodium depletion.
