When an individual's kidneys can no longer remove enough waste and fluid from their body, hemodialysis is required. This process can only remove a certain amount of fluid at a time, and waste can build up between treatments, making the patient unwell. Therefore, it is important to control what you eat and drink while on hemodialysis. One of the key components to monitor is calcium. Too much phosphorus in the blood pulls calcium from the bones, weakening them and making them more likely to break. This is why it is important to reduce calcium levels in a hemodialysis diet.

Phosphorus binds with calcium, so a high phosphorus diet can lead to calcium deposits in the blood vessels and heart
Phosphorus is the second most abundant mineral in the body, after calcium. It is essential for the body, playing a role in keeping teeth and bones strong, balancing pH levels in the blood, and helping nerves and muscles to function. Phosphorus is also needed for the growth, maintenance, and repair of cells and tissues, as well as for the production of DNA and RNA.
While phosphorus is essential, too much can be harmful. High phosphorus, or hyperphosphatemia, is often a symptom of chronic kidney disease. When the kidneys are damaged, they are less able to filter out extra phosphorus from the blood. This can lead to a buildup of phosphorus, which in turn pulls calcium from the bones, causing them to weaken and become more likely to break.
Additionally, high phosphorus levels can lead to calcium deposits in the blood vessels, heart, and other parts of the body. This can increase the risk of heart damage, heart disease, heart attacks, and stroke. Therefore, it is important to manage hyperphosphatemia through a combination of medication, dialysis, and dietary changes.
Dietary sources of phosphorus include meat, milk, poultry, fish, nuts, peanut butter, beans, cola, tea, and other dairy products. Phosphorus is also added to processed foods to maintain colour and moisture and to help preserve frozen foods. As such, limiting processed foods can help to reduce phosphorus intake.

Excess calcium can cause hypercalcemia, which can lead to cardiovascular disease
When an individual has chronic kidney disease (CKD), maintaining the proper calcium levels in the body is crucial. While the exact amount should be determined by a doctor, the Kidney Disease Outcomes Quality Initiative (KDOQI) recommends a range between 8.4 to 10.2 mg/dL.
Excess calcium can cause hypercalcemia, a condition characterised by higher-than-normal levels of calcium in the blood. Hypercalcemia can be caused by excessive intake of calcium, vitamin D or vitamin A supplements, or certain medications and conditions. It can also be caused by an overactive parathyroid gland, which is responsible for producing the hormone that controls blood calcium levels.
The symptoms of hypercalcemia can vary in severity and include more frequent urination and thirst, nausea, vomiting, constipation, decreased appetite, muscle aches, weakness, and cramping. In severe cases, it can lead to hypercalcemia-induced heart failure. Research has also found a link between higher calcium levels in the bloodstream and an increased risk of developing coronary artery disease and heart attack. This is particularly true for individuals with a genetic predisposition to higher calcium levels.
Therefore, for those on a hemodialysis diet, it is important to monitor and control calcium intake to maintain healthy blood calcium levels. This can be achieved by reading nutritional labels and being aware of foods that are high in calcium or have added calcium. Consulting with a renal dietitian can help individuals plan meals and make informed choices about their calcium intake to maintain optimal health.

High calcium levels can cause hyperparathyroidism, which can lead to mineral bone disorders
Calcium is essential for maintaining healthy teeth and bones, as well as for nerve cell signal transmission and muscle contraction. However, an elevated calcium level in the blood, known as hypercalcemia, can lead to health issues. This condition is often associated with hyperparathyroidism, which is caused by an overproduction of the parathyroid hormone by the parathyroid glands.
Hyperparathyroidism can cause high calcium levels in the blood, resulting in a range of health complications. The parathyroid hormone regulates calcium levels in the bloodstream and tissues, playing a crucial role in nerve and muscle function, as well as bone health. When the parathyroid glands become overactive, they secrete excessive parathyroid hormone, leading to hypercalcemia. This, in turn, can cause calcium buildup in the kidneys, blood vessels, heart, and other body parts.
Primary hyperparathyroidism is the most common form of the condition and is typically triggered by a growth or enlargement of one or more parathyroid glands. This results in the excessive production of the parathyroid hormone, which leads to elevated calcium levels in the blood. Secondary hyperparathyroidism, on the other hand, is often a result of another disease that initially causes low calcium levels in the body. As the body works to raise calcium levels, parathyroid hormone levels increase over time. This type is frequently seen in individuals with kidney disease or following specific intestinal surgeries.
The complications of hyperparathyroidism are largely due to the imbalance of calcium in the body, with too much calcium in the blood and not enough in the bones. This can lead to osteoporosis, where bones become weak, brittle, and prone to fractures. Additionally, kidney stones may form due to calcium buildup in the kidneys. Cardiovascular issues, such as high blood pressure and heart disease, have also been linked to high calcium levels in the blood.
To manage hyperparathyroidism and the associated calcium imbalances, treatment options include surgery and medication. Surgical removal of the abnormal parathyroid gland(s) is often recommended, particularly for younger patients, those with osteoporosis or kidney stones, and those with impaired kidney function. Medications may also be prescribed to reduce bone loss and lower blood calcium levels.

Calcium homeostasis is impaired in CKD, so oral calcium intake must be limited to maintain balance
Calcium homeostasis refers to the regulation of blood and intracellular calcium levels. The goal of calcium homeostasis is to maintain blood levels of calcium at appropriate levels for physiologic function. In healthy individuals, the calcium-sensing receptor (CaSR) allows for minute-to-minute regulation of calcium levels.
However, calcium homeostasis is impaired in CKD, which stands for chronic kidney disease. This impairment can lead to hypercalcemia, or elevated blood calcium levels, which is associated with various health risks. For example, hypercalcemia can cause the progression of cardiovascular diseases (CVD) and mineral bone disorders (MBD).
To maintain calcium homeostasis in CKD, oral calcium intake must be limited to less than 800-1000 mg per day. This is because, in CKD, the formulas for 'correcting' calcium are notoriously inaccurate, and excessive lowering of serum calcium during hemodialysis can lead to hypotension and cardiac rhythm disturbances. Therefore, it is essential to closely monitor your kidney diet and be aware of your calcium intake.
A renal dietitian can help you plan your meals and achieve healthy calcium levels. They will take into account various factors, including your hemodialysis treatment schedule, nutrition status, and lab results for phosphorus, potassium, and albumin levels.

Calcium-fortified foods are common, so reading nutritional labels is important to avoid excess calcium
Calcium is an essential mineral that helps promote healthy bones, teeth, and cells. It is well-known for its key role in bone health and is one of the best-selling supplements in the U.S. Calcium-fortified foods are common, added to a wide array of foods including fruit juices, cereals, and breads.
When you have chronic kidney disease (CKD), it is important to maintain the proper calcium levels in your body. The exact amount should be determined on a case-by-case basis by your doctor, but the Kidney Disease Outcomes Quality Initiative (KDOQI) recommends a range between 8.4 to 10.2 mg/dL. To maintain these levels, it is crucial to closely monitor your kidney diet and be aware of your calcium intake.
For people experiencing high calcium levels, it is recommended to limit foods that are naturally high in calcium. Reading nutritional labels is important to avoid excess calcium. Nutritional labels list the calcium content as a percentage, and by reading them, you can identify foods that have more than 10% calcium and should be avoided. If you are unsure about a particular food, consult your renal dietitian.
By planning your meals and grocery shopping ahead of time, you can more easily achieve healthy calcium levels. It is also important to note that portion size is a crucial factor when determining what to eat. Websites like DaVita.com offer kidney-friendly recipes for people on dialysis, which can help you manage your calcium levels.
