Blood Sugar (Definition)

The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human or animal. The body naturally tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is the primary source of energy for the body's cells, and blood lipids (in the form of fats and oils) are primarily ...Read more

II eat no more 20 carbs a day. My blood sugars have been in the 50's, 60's & 70's. Can low potassium cause low blood sugar readings or my carb intake?

II eat no more 20 carbs a day. My blood sugars have been in the 50's, 60's & 70's. Can low potassium cause low blood sugar readings or my carb intake?

It's lack of carbs: Why limit your carbs to 20g daily? Why are you checking your blood sugars? As you ought to know if you are doing this experiment, your body will eventually deplete its natural stores of glucose and eventually have impaired gluconeogenesis, leading to ketosis, a state that some seek for extreme weight loss, as fat is mobilized to provide alternative ketone-related energy. Be careful! Good luck ...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

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

I was in ER due to low potassium from blood pressure drug chlorlithidone to find also I was over medicated on Synthroid (thyroxine) to how long till side eff gone?

Resolve quickly: Hyperthyroidism can also lower blood potassium. Some people taking Chlorthalidone need extra potassium, others don't. If your synthroid (thyroxine) dose is correctly adjusted, and if you take some extra potassium, you should be fine. If you stick with the chlorthalidone, you should use rx potassium (can't do it with bananas). May be best to use another BP medication. ...Read more

What are the causes of low potassium, high blood pressure and palpitations?

What are the causes of low potassium, high blood pressure and palpitations?

Suspect hyperaldo: High blood pressure with low blood potassium levels brings the potential diagnosis of elevated aldosterone level (hyperaldosteronism) as a possibility.

There may be other reasons- for example if you are taking a BP medication that may cause low potassium levels but your BP is still elevated.

This finding requires a proper medical evaluation and lab analysis. ...Read more

I know potassium can lower blood pressure but can a symptom of low potassium be low blood pressure. Conflicting info on net?

A good relationship with a primary care physician is something you deserve. Best wishes. ...Read more
