Kidney stones can form when compounds in the urine– such as calcium, oxalate, and phosphorus– become highly focused. The body utilizes food for energy and tissue repair work. After the body uses what it requires, waste items in the blood stream are carried to the kidneys and excreted as urine.
Diet is among a number of elements that can promote or inhibit kidney stone formation. Specific foods might promote stone formation in people who are susceptible, however scientists do not think that eating any specific food causes stones to form in individuals who are not prone. Other factors that impact kidney stone development consist of genes, environment, body weight, and fluid consumption.
What are the Kinds of Kidney Stones?
4 significant kinds of kidney stones can form:
Calcium stones are the most typical type of kidney stone and happen in two major forms: calcium oxalate and calcium phosphate. Calcium oxalate stones are more common. Calcium oxalate stone development might be caused by high calcium and high oxalate excretion. Calcium phosphate stones are caused by the combination of high urine calcium and alkaline urine, meaning the urine has a high pH.
Uric acid stones
Uric acid stones form when the urine is persistently acidic. A diet abundant in purines– compounds found in animal protein such as meats, fish, and shellfish– may increase uric acid in urine. If uric acid ends up being concentrated in the urine, it can settle and form a stone by itself or along with calcium.
Struvite stones arise from kidney infections. Removing infected stones from the urinary tract and remaining infection-free can avoid more struvite stones.
Cystine stones arise from a congenital disease that causes cystine to leak through the kidneys and into the urine, forming crystals that tend to accumulate into stones.
Why is knowing which kind of kidney stone a person has crucial?
The first step in preventing kidney stones is to comprehend what is causing the stones to form. This details helps the health care carrier recommend diet changes to prevent future kidney stones.
For instance, limiting oxalate in the diet may assist avoid calcium oxalate stones however will do nothing to prevent uric acid stones. Some dietary suggestions might use to more than one type of stone. Most significantly, drinking enough fluids assists avoid all kinds of kidney stones by keeping urine weakened and flushing away materials that might form stones.
How to Avoid Kidney Stones
- When you are aiming to treat somebody with kidney stones or when you are aiming to prevent the recurrence of these annoying stones, you will need to understand what type of foods influence their development and which ones hinder it. Here are some tips:
Individuals who have kidney stones that are calcium based need to prevent foods like peas, items made from entire wheat flour, spinach, turnips, cauliflower, coconuts, and carrots.
- Those who deal with routine kidney stones that are made from uric acid or urine crystals alone need to avoid pickles, cucumbers, tomatoes, radishes, and onions.
Cabbage, beans, asparagus, and carbonated drinks must also be removed from the diet when an individual has kidney stones that have to be dealt with.
- Other foods that those with uric stones need to avoid include those foods that can enhance a person’s uric acid like liver, kidney, and other innards.
- Particular citrus juices have actually been seen to aid with some types of kidney stones. Attempt to enhance your consumption of grapefruit juice, cranberry juice, and orange juice.

Diet and Kidney Stones
I had a calcium stone
What type of diet should I follow? Will I need to avoid high calcium foods?
Calcium is not the enemy. If you have high calcium in the urine then sodium decrease is valuable for stone avoidance. Rather of decreasing your calcium intake, concentrate on restricting the sodium in your diet and set calcium-rich foods with oxalate-rich foods. Additional salt causes you to lose more calcium in your urine, putting you at risk for establishing another stone.
Your doctor will probably advise you to restrict sodium to 2,000 milligrams every day. There are lots of sources of “hidden” sodium such as canned or commercially processed foods in addition to restaurant-prepared and junk foods. A dietitian help you understand food labels and make changes in the quantity of sodium that you eat.
If you do not have high calcium in the urine then for stone decrease you might be better off focusing on other dietary changes. Your doctor or signed up dietitian can help determine if you require basically calcium and help you prepare a diet that is healthy.
I had an oxalate stone
What type of diet should I follow? Do I have to prevent foods high in oxalate?
Calcium oxalate kidney stones are the leading type of kidney stones. Oxalate is naturally discovered in many foods, consisting of vegetables and fruits, nuts and seeds, grains, beans, and even chocolate and tea. Some examples of foods which contain high levels of oxalate include: peanuts, rhubarb, spinach, beets, chocolate and sweet potatoes.
The oxalate content of food can differ due to differences in such things as soil quality and state of ripeness. There may be variation in released information, too, as different approaches may be used to determine the oxalate content of food.
Some research suggests that restricting high oxalate foods might help reduce your opportunity of forming another oxalate stone. However, many high oxalate foods are healthy so it is wise to not overly limit your diet if not needed. Most kidney stones are formed when oxalate binds to calcium while urine is produced by the kidneys.
New research suggests that consuming calcium and oxalate-rich foods together during a meal is a much better approach than restricting oxalate entirely due to the fact that oxalate and calcium are most likely to bind to one another in the stomach and intestinal tracts prior to the kidneys start processing, making it less most likely that kidney stones will form.
I had a uric acid stone
What does that imply? What type of diet should I follow?
Another common type of kidney stone is a uric acid stone. Red meat and shellfish have high concentrations of a natural chemical substance known as a purine. High purine consumption results in a greater production of uric acid which then builds up as crystals in the joints, or as stones in the kidneys.
To prevent uric acid stones, cut down on high-purine foods such as red meat, organ meats, and shellfish, and follow a healthy diet which contains mostly veggies and fruits, whole grains, and low fat dairy products. Limitation sugar-sweetened foods and drinks, specifically those that contain high fructose corn syrup. Eating less animal-based protein and eating more vegetables and fruits will help decrease urine acidity and this will help reduce the possibility for stone formation.
You must also make sure to drink a minimum of 3 quarts (12 cups) of water a day to assist reduce the risk for stone development. Making these healthy lifestyle changes can likewise help in reducing your risk for developing gout due to the fact that high uric acid is a leading risk element for gout.
Lowering the quantity of animal protein might help. Sources of animal protein include beef, chicken, fish and eggs. The majority of people require only 4 to 6 ounces of high protein foods and three portions of milk or cheese a day. Talk to your doctor or dietitian to be sure your protein intake is enough, however not excessive.
Chronic kidney stones are often treated with potassium citrate. Studies have shown that limeade, lemonade and other fruits and juices high in natural citrate might provide similar stone-preventing benefits. It is believed that citrate in the urine might avoid the calcium from binding with other constituents that result in stones. Likewise, some proof suggests that citrate might avoid crystals that are already present from binding with each other, thus preventing them from growing. Please note that juices made from actual limes and lemons consist of greater levels of citrate and beware of the sugar content in juices, because this can increase kidney stone risk.
Will it help/hurt me to take a vitamin or mineral supplement?
The B vitamins (that include thiamine, riboflavin, niacin, B6 and B12) have not been shown to be hazardous to people with kidney stones. In truth, some studies have shown that B6 might in fact help individuals with high urine oxalate. Nevertheless, check with your doctor or dietitian for suggestions on making use of vitamin C, vitamin D, fish liver oils or mineral supplements including calcium given that some supplements can increase the chances of stone development in some individuals.
Good luck! Have a nice weekend.
