Once calcium is confirmed to be elevated, a detailed history taken from the subject, including review of medications, any vitamin supplementations, herbal preparations, and previous calcium values. Chronic elevation of calcium with absent or mild symptoms often points to primary hyperparathyroidism or Familial hypocalciuric hypercalcemia. For ...
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
Disorders of calcium metabolism occur when the body has too little or too much calcium. The serum level of calcium is closely regulated within a fairly limited range in the human body. In a healthy physiology, extracellular calcium levels are maintained within a tight range through the actions of parathyroid hormone , vitamin D and the calcium ...
Unlike calcium carbonate, calcium gluconate does not require stomach acid for absorption, making it suitable for individuals with low stomach acid production or those taking acid-reducing medications. Calcium gluconate is commonly used in emergency medicine to treat conditions like hypocalcemia (low calcium levels) and hyperkalemia (high ...
For a healthy individual, if calcium levels are high, the kidneys will decrease its production of calcitriol (active vitamin D) by reducing the hydroxylation of calcidiol (inactive vitamin D); lower calcitriol levels means a lower rate of calcium absorption in the small intestine, which eventually offsets the elevated calcium levels.

Older adults with calcium and magnesium deficiencies also had poorer cognitive performance compared to peers with adequate micronutrient levels, a recent study has found.
Exercise can cause a release of potassium into bloodstream by increasing the number of potassium channels in the cell membrane. The degree of potassium elevation varies with the degree of exercise, which range from 0.3 meq/L in light exercise to 2 meq/L in heavy exercise, with or without accompanying ECG changes or lactic acidosis.
