Have low potassium, going to dr. To check kidneys, also have hot flashes, red hot face and hands, few times had high blood sugar. Possible diabetes?

Need for blood test: I trust that you plan to be fasting for your doctor's appointment so that fasting blood sugar may be tested. Though hemoglobin a1c can be tested in non-fasting state. It is not feasible to provide an answer without the lab tests. ...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

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

What does a high potassium level mean? What about a low potassium level?

What does a high potassium level mean? What about a low potassium level?

Long list of answers: High k (potassium) can be from lab error, released from red cells or from taking in more than the kidneys can remove. Typically from kidney trouble. Some medications make this more possible. Low k is found in patients who are volume depleted, drugs such as Lasix (furosemide) can make this happen. Some kidney diseases lead to k loss. These problems need expert attention. K problems are serious. ...Read more

Can a 3.60 (slightly low) potassium level go to normal with simple changes in diet for one or two days or is longer time needed for improvement? Thnx

Low K: There should be a reason why you K is low. Are you on meds? Diarrhea etc. diet may help but if you have gon goon losses k may not rise just with diet. Determining the cause is key.

I had a CBC done and it showed a slight low potassium level. Would this cause small red dots on legs and hands?

Does not add up: All laboratory results need to be interpreted in the clinical context and the doctor who ordered the tests is usually in the best position to do that. Having said that, CBC does not measure potassium so the information you provided is not reliable and you should consult the doctor who ordered the test. ...Read more

Heart palpitations and diahhrea. I have a heart murmur but I seen the heart doc not to long ago and everything was ok. I did have low potassium level.

Restore potassium: Your potassium must be restored to normal before anything else. Additionally your RBC magnesium level needs to be checked and also followed as the magnesium level affects potassium level and both can precipitate arrythmias. The diarrhea probably caused the initially low potassium. Make sure you don't have an infection. Meantime rehydrate with an electrolyte drink to restore fluid and minerals. ...Read more

Could you have Vipoma w/ out diarrhea? I have had low pottasium, numbness, weakness, hot flashes, high vip test, temp paralysis, low heart rate, dehyd

It comes and goes: VIP levels and diarrhea fluctuate. This is an uncommon condition best managed with a team approach. Adrenal insufficiency and other conditions that cause diarrhea have by now been excluded I would assume. You should have a good talk with your gastroenterologist about what to expect. ...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?

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

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

Insulin 64 after high carbs and glucose 54 & hypokalemia. I'm hypokalemic PP diagnosed but wonder if congenital hyperinsulin can cause low potassium?

Insulin and carbs: Rachel,
I wish I could help you but your comments are unclear.
What do you mean by "insulin 64" and glucose 54?

Have you been told that you have "congenital hyper-insulin"? In that case your doctor would have referred you to a surgeon.

Can exercise & glucose shift potassium in a healthy person? I'm diagnosed hkpp, getting 2nd opinion. Hypoglycemia & random hypokalemia. What else???

Can exercise & glucose shift potassium in a healthy person? I'm diagnosed hkpp, getting 2nd opinion. Hypoglycemia & random hypokalemia. What else???

Hkpp?: Exercise drives sugar into cells and would cause hypoglycemia if your liver failed to metabolize glycogen and couldn't perform gluconeogenesis. An insulin secreting tumor should be ruled out. Exercise should not affect potassium unless you have a metabolic disorder (low potassium from alkalosis, high potassium from acidosis). Are you seeing an endocrinologist? ...Read more
