What are the side effects of having too much calcium?

As a healthcare professional with expertise in nutrition and its effects on the human body, I can provide you with information on the potential side effects of having too much calcium. Excessive calcium intake can lead to a condition known as hypercalcemia, which is characterized by high levels of calcium in the blood. The side effects of hypercalcemia can range from mild to severe, depending on the level of calcium in the blood and the individual's overall health. Mild increases in blood calcium levels can cause symptoms such as nausea, poor appetite, vomiting, and constipation. These symptoms may not be immediately apparent and can be mistaken for other gastrointestinal issues. As calcium levels rise to moderate high levels, individuals may experience fatigue or a sense of excessive tiredness. This can impact daily activities and overall quality of life. More severe symptoms of hypercalcemia include heart rhythm abnormalities, which can be life-threatening if not addressed promptly. Additionally, increased urinary frequency and the formation of kidney stones are common, as the excess calcium can crystallize in the kidneys and urinary tract. It's important to note that while calcium is essential for bone health and other bodily functions, it should be consumed in appropriate amounts. The recommended daily allowance (RDA) for calcium varies by age and sex, and it's always best to consult with a healthcare provider to determine the right amount for your specific needs.

However, symptoms of nausea, poor appetite, vomiting and constipation may be present with mild increases in blood calcium levels. Moderate high levels of hypercalcemia may produce fatigue or excessive tiredness. Heart rhythm abnormalities, increased urinary frequency, and kidney stones may also be present.
