In this article, we review the roles of calcium and phosphorus, including calcium and phosphorus have an inverse relationship: when calcium levels increase. Hypertension.

A high potassium level has many causes, including kidney disorders, drugs that affect kidney function, and consumption of too much supplemental potassium.
Diagnosis Measurement of potassium level in the blood Usually, hyperkalemia is first detected when routine blood tests are done or when a doctor notices certain changes on an electrocardiogram ECG. To identify the cause, doctors evaluate a person's medical history, determine which drugs people have been taking, and do blood tests to check for evidence of diabetes mellitus, acidosis, muscle breakdown, or kidney disorders.
Treatment Drugs to increase potassium excretion The disorder that is causing hyperkalemia is treated.

Mild hyperkalemia For mild hyperkalemia, reducing consumption of potassium or stopping drugs that prevent the kidneys from excreting potassium may be all that is needed. If the kidneys are functioning, a diuretic that increases potassium excretion may be given.
If needed, a resin that absorbs potassium from the digestive tract and passes out of the body in the stool can be given by mouth or enema. Sodium polystyrene sulfonate is a potassium-absorbing resin that is effective but used only for short periods because it can cause excess sodium to be retained.
Calcium Absorption & Potassium
Patiromer is a resin drug that can be used for longer periods. It is useful for people who require drugs that usually raise potassium levels, such as angiotensin-converting enzyme ACE inhibitors for treatment of heart or kidney disease.
Moderate to severe hyperkalemia For moderate to severe hyperkalemia, the potassium level must be reduced immediately.
Age is another factor that affects calcium absorption, which is at its highest during infancy and the early childhood years. Absorption decreases in adulthood and continues to decrease as you age. The foods you eat can also reduce the absorption of calcium. Phytic acid and oxalate acid bind to calcium, reducing its absorption. Whole grains, nuts and seeds are some of the foods high in phytic acid. Sources of oxalic acid include beans, sweet potatoes and rhubarb.
Decreased Calcium Excretion Adding more potassium to a high-sodium diet can help decrease calcium excretion, particularly in postmenopausal women. According to the National Institutes of Health, women who include enough calcium in their diets may be able to slow the rate of bone loss.
Potassium-sparing diuretics can also decrease the amount of calcium excreted in urine, thereby increasing calcium levels in the blood. As a result, a higher intake of potassium may help prevent kidney stones from forming. The chemical stimulant caffeine can increase calcium excretion, reducing absorption, although the effect is minimal.
Alcohol also reduces calcium absorption by blocking enzymes in the liver that help convert vitamin D to its active form. Hyperkalemia Hyperkalemia — a common cause of cardiac arrhythmias — occurs when the level of potassium in the blood is higher than normal.
Symptoms of hyperkalemia include muscle weakness, fatigue, irregular heartbeat or sudden cardiac arrest.
