Causes of Hyponatremia in Cancer Patients
Can low sodium levels indicate cancer?
—A low serum sodium may portend a diagnosis of cancer according to the results of a nationwide, population-based cohort study of more than 16,000 Danish men and women with newly detected hyponatremia. Physicians may soon have a new way to help predict cancer at earlier stages.
Does low sodium mean lung cancer?
Hyponatremia is an emerging issue in cancer patients, especially those affected by lung cancer. Among different causes of hyponatremia, SIADH plays a central role due to its frequency especially in SCLC, but it should be suspected also in other tumors, such as NSCLC.
Can pancreatic cancer cause low sodium levels?
The most common types of cancer with a significant incidence of hyponatremia include solid tumors, such as small-cell lung cancer, pancreatic cancer, gastric cancer, and renal cell cancer, as well as some hematologic malignancies.
Do brain tumors cause low sodium?
Hyponatremia is a frequent electrolyte imbalance in hospital inpatients. Acute onset hyponatremia is particularly common in patients who have undergone any type of brain insult, including traumatic brain injury, subarachnoid hemorrhage and brain tumors, and is a frequent complication of intracranial procedures.
Will eating more salt help hyponatremia?
In elderly patients with a diet poor in protein and sodium, hyponatremia may be worsened by their low solute intake. The kidney’s need to excrete solutes aids in water excretion. An increase in dietary protein and salt can help improve water excretion.
What diseases cause low sodium?
A low sodium level has many causes, including consumption of too many fluids, kidney failure, heart failure, cirrhosis, and use of diuretics. Symptoms result from brain dysfunction.
How long does it take to recover from low sodium levels?
Generally, low sodium is asymptomatic (does not produce symptoms), when it is mild or related to your diet. It can take weeks or months for you to experience the effects of low salt in your diet—and these effects can be corrected by just one day of normal salt intake.
Is Low Sodium bad?
Low blood sodium is common in older adults, especially those who are hospitalized or living in long-term care facilities. Signs and symptoms of hyponatremia can include altered personality, lethargy and confusion. Severe hyponatremia can cause seizures, coma and even death.
What is the survival rate for lung cancer?
The lung cancer five-year survival rate (18.6 percent) is lower than many other leading cancer sites, such as colorectal (64.5 percent), breast (89.6 percent) and prostate (98.2 percent). The five-year survival rate for lung cancer is 56 percent for cases detected when the disease is still localized (within the lungs).
Which organ is most affected by hyponatremia?
Hyponatremia occurs when your blood sodium level goes below 135 mEq/L. When the sodium level in your blood is too low, extra water goes into your cells and makes them swell. This swelling can be dangerous especially in the brain, since the brain cannot expand past the skull.
What does low sodium mean in a blood test?
If your results show lower than normal sodium levels, it may indicate: Diarrhea. Vomiting. Kidney disease. Addison disease, a condition in which your body’s adrenal glands don’t produce enough of certain types of hormones.
Can stress cause low sodium levels?
The author explained that it is natural for the body to react to stress by increase blood vessel constriction for a short period of time, therefore raising sodium elimination.
What does low sodium do to the brain?
In acute hyponatremia, sodium levels drop rapidly — resulting in potentially dangerous effects, such as rapid brain swelling, which can result in a coma and death. Premenopausal women appear to be at the greatest risk of hyponatremia-related brain damage.
Does low sodium cause memory?
A rapid, acute drop can lead to temporary brain cell dysfunction, including memory loss, Dr. Messina said. “If it happens over a day or two, you can usually reverse it pretty quickly and get the patient feeling normal.”
Can low sodium cause a stroke?
Compared with people who had an average sodium intake, the rates of heart attack, stroke, and death were higher among those who had a low sodium intake, regardless of whether participants had high blood pressure.
