Introduction
One morning, Rajiv, a 42-year-old, woke up with severe lower back pain assuming it was just muscle strain. He tried to ignore it, but the discomfort worsened, spreading to his abdomen. A visit to the emergency room and a few tests later revealed some unexpected kidney stones caused by excess calcium in urine.
Rajiv’s experience is not uncommon. When the body’s calcium balance is disrupted, it can lead to hypercalciuria, a condition where too much calcium is excreted in the urine. Left unchecked, it may cause kidney stones or urinary tract irritation.
But what causes this excess calcium? What calcium in urine symptoms should one watch for? And how can this be treated effectively? This article explores the causes, symptoms, and treatment options for high calcium in urine, helping you understand when it requires medical attention.
Causes of High Calcium in Urine
The reasons for increased calcium levels in urine are many and more often than not; they include dietary habits or a factor leading to some medical conditions. Here are a few:
Diet and Absorption Problems
A restaurant offering calcium and vitamin D may lead to absorption in the intestines and, as a result, the raising of levels excreted through the urine. It may also be the case sometimes that calcium carbonate used in the treatment of osteoporosis could cause excess calcium carbonate in urine.
Hyperparathyroidism
One of primary medical causes of hypercalciuria is hyperparathyroidism. It is a poorly controlled release of parathyroid hormone from parathyroid glands, raising calcium levels in the blood and in due course, urine.
Kidney Disorders
The kidneys sometimes lose their ability to reabsorb calcium properly, so the inappropriate amount of calcium gets passed in the urine. This condition is called "renal leak" and may be due to genetic mutations or diseases of the kidneys.
Medications
Diuretics and lithium therapy have been linked with increased calcium levels in urine, just like corticosteroids have.
Other Conditions
-
Sarcoidosis and tuberculosis can cause calcium imbalance.
-
When immobilization occurs (this means no movement), calcium is released from the bones into the bloodstream.
-
Moreover, cancer can also increase calcium levels in the body.
Idiopathic Hypercalciuria
In some, no exact reason can be identified. Thus, focusing on idiopathic hypercalciuria is of mountain-size importance-the prime reason for kidney stones.

Calcium in Urine - Symptoms
High calcium in urine, if not noticed, causes its complications that take over. Some people might feel a number of calcium in urine symptoms such as:
Frequent Urination
The kidneys move into overdrive to get rid of the extra calcium causing frequent urination or sudden urge to urinate.
Abdominal or Flank Pain
Pain along the sides or in the lower back may be due to kidney stones, one of the common complications of high calcium in urine.
Blood in Urine (Hematuria)
Kidney stones or irritation of the urinary tract could cause blood in the urine because of excess calcium.
Nausea and Fatigue
Hypercalcemia accompanied by increased calcium excretion in urine, may present with the symptoms of nausea, tiring fatigue, or confusion.
Early recognition of symptoms of calcium in urine is key to preventing the development of other serious problems such as chronic kidney disease.
How to Treat High Calcium in Urine
Treatment is based on the causal factor. The following are most often prescribed methods:
Medications
-
Thiazide diuretics: Decrease calcium excretion by stimulating calcium reabsorption by the kidneys.
-
Potassium citrate: Sometimes prescribed to help prevent kidney stones.
Dietary Changes
Counterintuitively, it is not always best to drastically lower calcium intake. Instead, consider the following:
-
Reduce sodium: high salt levels increase calcium loss in the urine.
-
Limit animal protein intake.
-
If taking calcium supplements, discuss calcium carbonate with your physician to ensure you are not excreting calcium carbonate excessively in the urine.
Hydration
Increasing fluid intake will dilute the urine, lowering calcium concentration and decreasing the chances of crystal aggregation. The first step is to keep well hydrated.
Treating Underlying Conditions
In case of hyperparathyroidism, surgery to remove overactive parathyroid glands might be necessary. Moreover, your doctor should also treat kidney diseases or modify medications which contribute to high calcium in urine.
Monitoring
Your doctor might want to order some tests for calcium in urine like 24-hour urine collection or random urine calcium-to-creatinine ratio. These tests would be good for monitoring the treatment effectiveness and adjusting the therapeutic strategies as needed.

Conclusion
The condition of having high calcium in urine should not be taken lightly. Whereas some cases are benign, the others may pose a larger concern such as hyperparathyroidism, ill kidney action, and almost to some degree poor diet. Recognizing calcium in urine symptoms, having the right diagnosis, and proper treatment will prevent kidney stone complications or long-term kidney damage. If you experience the symptoms or find yourself at risk, see a healthcare provider and get tested for calcium in urine to ensure your urinary calcium levels are within a healthy range.

FAQs
What is a normal range of calcium in a 24-hour urine test?
The normal range for calcium in urine in a 24-hour analysis usually changes from 100 to 250 mg for females and from 100 to 300 mg for males. But these conditions also vary according to each laboratory.
Is calcium in urine dangerous?
Not always, but ongoing hypercalciuria may predispose the patient to kidney stone formation, while it is indicative of other secondary causes such as hyperparathyroidism or renal tubular stuff that need a medical query.
How do you test for calcium in urine?
The 24-hour urine collection is mainly used in calcium-in-urine tests to measure calcium excretion. There are also times when an early morning urine calcium-to-creatinine ratio is measured.
Can diet affect calcium levels in urine?
Yes, foods rich in salt, animal protein, or calcium supplementation (especially calcium carbonate) may be the cause of increased calcium in the urine. Proper diet fixes calcium excretion.
Can dehydration lead to high urine calcium?
Yes. Dehydration lowers urine volume, concentrating calcium and increasing the chance of stone formation and other complications.
