What happens if my vitamin D is too high?

Answered by Cody Janus

If your vitamin D levels are too high, it can have negative effects on your health. When the levels of vitamin D in your blood exceed 375 nmol/L or 150 ng/mL, it is considered to be excessively high and can lead to various symptoms and complications.

One of the first symptoms you may experience is nausea and vomiting. This can be quite uncomfortable and may lead to a loss of appetite. Along with these symptoms, you may also feel muscle weakness and pain. This can make it difficult to carry out daily activities and may impact your overall quality of life.

Excessive levels of vitamin D can also cause confusion and mental changes. You may find it difficult to concentrate or feel disoriented. This can be particularly concerning, especially if you have important tasks or responsibilities to fulfill.

Dehydration is another possible consequence of high vitamin D levels. You may feel excessively thirsty and experience frequent urination. It is important to stay well-hydrated and monitor your fluid intake if you suspect your vitamin D levels are too high.

In some cases, high levels of vitamin D can lead to the formation of kidney stones. These are hard deposits that form in your kidneys and can be extremely painful. If you have a history of kidney stones or are at risk for developing them, it is crucial to be cautious with your vitamin D intake and monitor your levels regularly.

It is important to note that these symptoms and complications typically occur when vitamin D levels are extremely high. Most people do not experience such high levels of vitamin D unless they are taking excessive doses of supplements without medical supervision. However, it is always recommended to consult with a healthcare professional before starting any new supplements or significantly increasing your vitamin D intake.

While vitamin D is crucial for maintaining good health, too much of it can have harmful effects. It is essential to maintain a balanced and appropriate level of vitamin D in your blood to avoid the potential complications associated with excessive intake. Regular monitoring and consulting with a healthcare professional can help ensure that your vitamin D levels remain within a safe range.
