Hoping you can tell me, is constant low potassium level a sign of cancer?

Hoping you can tell me, is constant low potassium level a sign of cancer?

Nephrologist: Potassium balance is tightly regulated by the kidneys, so any potassium disorder implies some derangement in potassium intake or output. Low potassium could be due 1. To decreased intake, 2. Physiological shifts and 3. Increased loss in the stools or urine. It is best to consult nephrologist. ...Read more

Cancer (Definition)

Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more

Do doctors always give patients potassium-sparing drugs if the patient has low potassium levels?

Do doctors always give patients potassium-sparing drugs if the patient has low potassium levels?

NeverSayAlwaysorNeve: If you are on a medication that tends to make you lose potassium, then the doctor could substitute or add another drug that helps you keep it. Another option would be to take potassium supplements as well as foods higher in potassium. The supplement/diet approach would also apply if for some reason your potassium was low. Other than that, it depends on your particular situation. ...Read more

Can low potassium cause fluid in the lungs of a heart patient? And how

Can low potassium cause fluid in the lungs of a heart patient? And how

Not usually.: Super low potassium (k) can sometimes cause arrhythmias and fluid backing up into the lungs from a poorly beating heart, but most of the time fluid building up in the lungs of a heart patient is due to too much sodium (salt) in the diet. Diuretics help the body get rid of excess sodium and can lead to low k in the process. Usually this low k causes muscle cramps before it leads to arrhythmias. ...Read more

In a r phlebotomist who recently drew a bladder cancer patient. The potassium result showed a false positive of 14. What caused this result?

Hemolysis: Since a potassium of 14 is incompatible withlife, the sample was undoubtedly hemolyzed. The only other thing that could drive the potassium to that high would be succinylcholine. Redraw the sample. ...Read more

I have hypokalemia which is low potassium in my blood should I play soccer today or wait?

Low potassium: You would be better off waiting for your potassium (k) levels to rise before you play soccer. The more important question is, why is your k low? Are you on any medications that would lower it, like diuretics? Do you have a low magnesium level? See a physician to get to the cause of your low k level. It is better to prevent a problem than treat it. ...Read more

I have a low potassium problem and kidney stones problem. Is my hypokalemia the cause of my kidney stones? Or the other way?

I have a low potassium problem and kidney stones problem. Is my hypokalemia the cause of my kidney stones? Or the other way?

Unlikely: A potassium-wasting problem might be due to kidney tubular / parenchymal damage from infection related to kidney stones, but in this case you would have been told of this by your physicians. If your potassium is actually significantly below the healthy range, this is serious and no physician would let it go without a full workup. You have a right to a thorough explanation from your doctor. ...Read more

If the majority of potassium in the body is in red blood cells and very little in serum why is serum potassium level used to diagnose hypokalemia?

If the majority of potassium in the body is in red blood cells and very little in serum why is serum potassium level used to diagnose hypokalemia?

It's what matters: The serum potassium is in equilibrium with the tissue concentrations, which must be maintained within a very narrow range for the heat to be able to maintain its beat. Your question is a good one and reflects a common misunderstanding. It's not the total body potassium that matters, just the amount that's actually affecting the electrical system outside the heart & brain cells. ...Read more
