As a general rule, is 99mg of Potassium once daily enough to correct a deficiency level of 3.2? And can this level cause shortness of breath?

As a general rule, is 99mg of Potassium once daily enough to correct a deficiency level of 3.2? And can this level cause shortness of breath?

More potassium: I recommend that individuals with a low potassium take supplements and eat potassium-rich foods several times per day. Take the supplements with your meals which helps with the absorption. Also increase foods with higher potassium in your diet such as bananas, orange juice, sweet potatoes, regular potatoes and cashews. The low potassium itself does not cause shortness of breath but weakness.

Insulin excess, mineralocorticoid (aldosterone - a hormone secreted by adrenal gld.) excess are associated with low potassium.There is a genetically acquired condition called periodic hypokalemic syndrome characterized by low k level.

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.

What causes a low blood calcium level? Mine is 8.5 and I already take potassium and magnesium. Do they have anything to do with it? Vit d 57.6

A calcium of: 8.5 is still normal. The calcium level is "total" calcium, of which 1/2 is bound to proteins. Have your doctor check your "ionized calcium" which is a much more accurate determination of whether your calcium is low or not. Low parathyroid hormone can cause low calcium, as can certain kidney diseases, and other problems. Make sure you are on calcium and d. Your d level is already ok. Check w/docto.

Can using albuterol cause a low potassium on your blood test?

Can using albuterol cause a low potassium on your blood test?

Useful in a pinch: Respectfully, for the reasons detailed by dr. Rubin, nebulized albuterol can be effective within 30 minutes to lower potassium by about 0.5 mmol/l. The effect lasts about 2 hours. Long enough for bicarbonate (sodium bicarbonate) and Insulin therapies to start working.

Does low potassium increase blood pressure? If so, could nebulized albuterol's potassium-lowering effect be a significant factor as the cause of hbp?

Does low potassium increase blood pressure? If so, could nebulized albuterol's potassium-lowering effect be a significant factor as the cause of hbp?

Not likely: While low intake of sodium and adequate intake of potassium may be useful in preventing high blood pressure, it is unlikely that albutrol is a major factor in causing high blood pressure.

Was diagnosed with hypokalemia after taking florinef (fludrocortisone). Same day I had blood work for nt-probnp. Could low potassium cause high bnp? Mine was high

Florinef (fludrocortisone): Florinef (fludrocortisone) causes salt and fluid retention. The fluid retention may cause a rise in bnp. Suggest you discuss result with your md. Lowering of the potassium is a known side effect of Florinef (fludrocortisone) use.
