Health: Excessive calcium intake is the cause of kidney stones, know here

[ad_1]

Calcium supplements are commonly taken to support bone health and prevent conditions such as osteoporosis. However, concerns have been raised about their possible role in the formation of kidney stones, a painful condition where solid particles develop in the kidneys. It is important to understand the relationship between calcium supplementation and kidney stones to make informed decisions about diet and supplement choices.

How are kidney stones formed?

Kidney stones are hard deposits that form in the kidneys when substances such as calcium, oxalate and phosphorus become concentrated in the urine. These crystals can come together to form small, pebble-like structures. Although they can live in the kidneys without causing symptoms, they can also travel through the urinary tract, causing severe pain if trapped. Kidney stones can be composed of a variety of substances, including calcium oxalate.

Symptoms of kidney stones

Symptoms of kidney stones include severe pain in the back or side, often spreading to the lower abdomen and waist. The intensity of pain may fluctuate and may also be accompanied by nausea, vomiting and blood in the urine. People may experience frequent urination and a persistent urge to urinate, as well as discomfort during urination. In some cases, fever and chills may be a sign of infection. The intensity of symptoms depends on the size of the stone and its movement within the urinary tract. If these symptoms occur, it is important to see a doctor, especially if they are associated with severe pain or signs of infection.

Is dietary calcium also a risk?

Studies show that dietary sources of calcium may not pose the same risk of stone formation as calcium supplements. Adequate dietary calcium intake may actually reduce the risk of stones by binding to oxalate in the intestines and preventing its absorption. The body has mechanisms to regulate the absorption of calcium from food sources. When calcium is obtained from food, these regulatory mechanisms help maintain the balance. However, calcium supplements, especially when taken in large amounts, can bypass these regulatory mechanisms, potentially leading to increased levels of calcium in the urine.

What is the cause of stones?

• Insufficient fluid intake can concentrate minerals in the urine, which contributes to stone formation.

• Consuming excessive amounts of calcium, whether through supplements or diet, may increase the risk of kidney stone formation. This is especially relevant for individuals who take calcium supplements in high doses without medical supervision.

• Foods high in oxalate, such as beets, chocolate, nuts and some leafy vegetables, can contribute to the formation of calcium oxalate stones if consumed in excess, especially in combination with high doses of calcium supplements.

• Some people are more likely to form stones due to genetic factors or underlying medical conditions. Such people may need to be more cautious about calcium intake, especially supplements.

what to do to stop

• Maintaining proper hydration is essential to prevent stones. Drinking enough water helps dilute the minerals in urine and reduces the risk of stone formation.

• Getting calcium from a balanced diet instead of a balanced diet may be a more prudent approach. Dairy products, leafy vegetables and fortified foods are good dietary sources of calcium.

• For individuals with calcium oxalate stones, it may be advisable to control intake of high-oxalate foods and consult a health care professional for personalized dietary recommendations.

• If calcium supplements are necessary, it is important to use them on doctor’s advice. Dosage should be individualized based on individual needs, and excessive supplementation should be avoided.
