Unmasking the Culprits: What's Behind Your Low Calcium Levels?
Published: Aug 17, 2024
Low calcium, or hypocalcemia, can stem from various causes. Understanding these can help you and your doctor pinpoint the issue and find the right treatment.

Parathyroid Problems: The Main Suspects
The parathyroid glands are tiny organs in your neck that control calcium levels. When they're not working properly, it's called hypoparathyroidism. This can happen after neck surgery, due to autoimmune diseases, or rarely, from genetic conditions. Think of the parathyroid glands as the body's calcium thermostat - when they're broken, your calcium levels can drop too low.
Vitamin D Deficiency: The Silent Thief
Vitamin D helps your body absorb calcium from food. Without enough of it, your calcium levels can drop. This can happen if you don't get enough sunlight, have certain digestive problems, or take medications that interfere with vitamin D. It's like trying to fill a bucket with a hole in it - without vitamin D, the calcium you consume might not stay in your body.

Kidney Troubles: The Calcium Balancing Act
Your kidneys play a crucial role in calcium balance. In chronic kidney disease, the kidneys may not activate vitamin D properly or may not be able to keep phosphate levels in check. High phosphate can cause calcium to drop. It's a bit like a seesaw - when phosphate goes up, calcium often goes down.
