Vitamin D toxicity

Vitamin D is an essential nutrient for the body's normal bone development and maintenance. It also aids the body's nervous system, musculoskeletal system and immune system.

Some of the ways in which you get vitamin D is from the sun, through food and drinks, and also through nutritional supplements and prescription medication.

If your body gets too much of vitamin D, you could get vitamin D toxicity. It is however, a rare condition, with about 4,500 cases per year in the United States, as per Cleveland Clinic.

The level of vitamin D at which people might experience toxicity could vary, but it could occur at levels as little as 2,000 international units per day (IU/d).

Vitamin D toxicity is not caused by just sun or food and drinks. Often, it happens due to over-consumption of prescription-strength vitamin D supplements. So if you consume these, do check your vitamin D levels regularly.

Symptoms of hypervitaminosis D

Hypervitaminosis D leads tohypercalcemia, which refers to higher-than-normal levels of calcium in your blood. The hypercalcemia caused by high levels of vitamin D, is responsible for most of the symptoms of hypervitaminosis D. They include:

  • Decrease in appetite
  • Nausea and vomiting
  • Constipation
  • Dehydration
  • Increased thirst (polydipsia)
  • Frequent urination
  • Confusion, lethargy and fatigue
  • Muscle weakness and difficulty walking
  • Bone pain
  • Kidney stones

Vitamin D toxicity is usually not fatal or life-threatening, but it can cause significant harm to your health. It can cause you to feel confusion and have an unsteady gait. In very serious cases, it can cause kidney failure or abnormal heart rhythm.
