There are sure things that you exercise that are generally accepted as healthy. Similar eating your vegetables, going to the gym, or cutting down on soft drinks.
But sometimes, in an ironic twist of events, doing what yous recall is best for your health could backfire on yous.
Take kidney stones, for example. They can be caused by eating too much of certain vegetables. Only more of that in a flake.
These hardened accumulations of minerals in your kidneys may exist the size of a common salt grain or as big as a corn kernel.
Larger kidney stones can fifty-fifty exist shaped similar the horns of a stag, said Dr Tan Yung Khan, an urologist from Urohealth Medical Clinic at Mount Elizabeth Novena Hospital.
"I have seen kidneys filled with multiple stones, and in some cases, the entire kidney is filled with stones," he said.

Pain AKIN TO BEING STABBED
Stones that are still in the kidneys (they tin can move to other parts of the urinary tract) may not cause whatever symptoms, and you may not even know of their presence, said Dr Tan.
But if a stone moves into the ureter and causes a blockage, that's when it tin cause pain that has been compared to that experienced in childbirth or being stabbed, co-ordinate to Healthline.
The pain often starts of a sudden, and is acquired by the blocked ureter contracting to push button the stone out.
The atrocious feeling comes in waves of a few minutes, and then goes abroad before coming back once more, noted Healthline.
The excruciating feeling doesn't stay in ane spot either. As the stone travels, you might feel it forth your side and back, just below your ribs.
When it moves down the urinary tract, the hurting may radiate to your belly and groin expanse.
Larger stones certainly crusade more than pain than smaller ones just sometimes, size doesn't matter.
"The usual stones we see are small-scale ones that get stuck in the ureter which then cause pain," said Dr Tan.
In addition to pain, at that place may be signs such equally claret in the urine, kidney infection and accompanying fever, and in severe cases, permanent damage to the kidney if not treated, he added.

HOW KIDNEY STONES ARE FORMED
It's no thanks to the loftier levels of minerals in your body. Think of kidney stones' germination this way: If y'all don't add enough water when stirring a loving cup of Milo, you'll end upwardly with difficult lumps in your drink.
The same thing happens in your kidneys when you lot don't drink enough water.
"Kidney stones are quite common. About one in 10 Singaporeans volition get kidney stones. It is slightly more mutual in males than females," said Dr Tan.
Equally for what causes the stones, it is largely determined by what you lot put – or don't put enough of – into your body. The mutual ones, co-ordinate to Mayo Clinic, are:
Calcium stones: This is the most common blazon of kidney stones, and are frequently in the form of calcium oxalate; oxalate is a chemical that occurs naturally in certain vegetables.
Calcium stones can also exist made of calcium phosphate, which is common in metabolic conditions, such equally renal tubular acidosis.
It may also exist associated with certain migraine headaches or taking certain seizure medications such as topiramate, according to the Mayo Dispensary.
Struvite stones: These usually course in individuals with urinary tract infections – sometimes, with picayune warning.
The stones can grow apace and become quite big, though there may not be signs.
Uric acrid stones: As the proper noun implies, these stones are acquired by an accumulation of uric acid.
It typically happens in people who don't drink enough fluids, and those who eat a high-protein nutrition or take gout.
Cystine stones: These stones are prone to occur in individuals with a hereditary disorder, where their kidneys excrete too much of an amino acid known equally cystinuria.

WHEN Salubrious HABITS MAY CAUSE KIDNEY STONES
Consuming too much of the "bad" stuff such as meat, salt and soft drinks can increase your gamble.
Only certain fruits and vegetables, too? And so, which is the more probable cause of kidney stones?
"The most common causes of kidney stones in Singapore are related to bereft fluid intake, as well much salt in the nutrition and too much poly peptide," said Dr Tan.
Still, it is interesting to notation that besides much of a adept thing can be bad for you.
Here are some examples of healthy habits or intentions that may increase your risk of or exacerbate your kidney stones:
- YOU Popular VITAMIN C Similar CANDY
Too much Vitamin C tin can be an issue as it combines with calcium to class calcium oxalate – a precursor to certain kinds of kidney stones.
"Vitamin C in high doses is a problem," said Dr Tan.
And by that, he ways doses of more than 500mg per day. "In fact, I would rather my patients keep to a maximum of 200mg per day," he said.
- You lot Have CALCIUM SUPPLEMENTS
Calcium supplementation in large quantities, and when taken separately from meals, may set up you up for kidney stones, co-ordinate to a written report published in the Translational Andrology And Urology (TAU) periodical.
But calcium is necessary for strong basic, and it is lacking in Singaporeans' diets, said Dr Tan.
Furthermore, although information technology sounds paradoxical, calcium tin can also prevent kidney stones.
"Calcium in the diet binds to the oxalate in nutrient, thus preventing the absorption of the oxalate, which is a key component of some types of kidney stones," said Dr Tan.
In fact, the solution to stone prevention may exist as simple as meeting your daily calcium intake of 1,000mg per twenty-four hours, co-ordinate to The University Of Chicago'southward Kidney Stone Evaluation And Treatment Program.
If calcium supplements are needed, the TAU report recommended taking them with a meal, especially for those who are decumbent to developing stones.
But if boosting your calcium intake doesn't lower your urine oxalate level, the same programme suggested watching your oxalate intake.
A typical diet has at least 200mg to 300mg of oxalate.
To prevent kidney stones, a reasonable goal is beneath 100mg of oxalate daily, or ideally, about 50mg daily.
- YOU Consume A LOT OF SPINACH AND NUTS
Some greens take more oxalate than others.
For instance, spinach, beet, beans, potato and yam are known to be oxalate powerhouses.
Merely that doesn't hateful y'all cut them out completely equally they also "have protective effects against kidney stones," said Dr Tan.
"Vegetables make urine more element of group i – and alkali helps inhibit stone germination.
"My usual advice for patients with oxalate stones is to abstain from taking besides much spinach," he said.
Other healthy foods such every bit nuts and seeds are loaded with oxalate, too.
And so, if you are decumbent to kidney stones (indications include a personal or family unit history, obesity, and medical conditions such as renal tubular acidosis and urinary tract infection) just like to kickoff your morning with a granola bowl topped with almonds and pumpkin seeds, you might want to agree back.
- Y'all'RE ON A HIGH-PROTEIN DIET TO LOSE WEIGHT
Information technology is always a practiced thought to keep a chapeau on your weight equally a loftier BMI has been linked to many health issues including heart diseases, diabetes and, yes, kidney stones.
Just if you are at risk of developing kidney stones, going on a high-protein diet to lose weight isn't a practiced thought.
Eating too much animate being protein, such equally ruby-red meat, poultry and seafood, boosts the level of uric acid, according to Harvard Health.
A high-protein diet as well reduces levels of citrate, the chemic in urine that helps forestall stones from forming.
"Another factor with a high poly peptide intake is that it causes increased acidity in the urine. Increased acidity predisposes one to many types of kidney stones," said Dr Tan.

MANAGING KIDNEY STONES
Depending on the size of the stone, the handling varies. "With pocket-sized stones that crusade minimal pain and no signs of infection, we can effort medical expulsive therapy (MET)," said Dr Tan.
This is essentially a prescription of alpha blocker medication to relax the muscles in your ureter to make information technology easier for the stone to pass, forth with drinking lots of water.
Painkillers may likewise be given considering even passing a small rock can cause severe discomfort.
Large stones that can't be rid of through passing urine will demand more all-encompassing treatment.
According to Dr Tan, this tin "range from shockwave therapy, scopes and lasers, and sometimes, tiny punctures made in the kidney to clear the larger stones".
The shockwave therapy or extracorporeal stupor moving ridge lithotripsy (ESWL) uses audio waves to create intense vibrations to break the stones into tiny pieces that can and so be passed in your urine.
The procedure lasts under an hour, and yous'll be sedated.
Sometimes, the handling method used may not successfully eliminate all the stones; for instance, stone fragments of various sizes may remain later on a session of ESWL, according to the National Kidney Foundation in the US.
A echo procedure – or a different procedure – may be needed.
In such instances, a procedure called percutaneous nephrolithotomy may be performed to surgically remove stones that ESWL tin can't dislodge.
It is washed using small telescopes and instruments inserted through a small incision in the back.
Unfortunately, if you have had a kidney stone, there is a 50 per cent chance yous'll accept another in five to 10 years, said Dr Roger Sur, managing director of the UC San Diego Comprehensive Kidney Rock Center.
In that location are certain foods such as lemons that may bring down the recurrence.
Citrus fruits are good inhibitors of kidney stones, and lemons are the all-time as they contain the highest concentration of citrate, said Dr Sur.
In his report, it was plant that drinking well-nigh 120ml of reconstituted lemon juice in ii litres of water per solar day decreased the rate of stone formation from 1.00 to 0.13 stones per patient.
Dr Tan also encourages his patients to include more citrus fruits in their diet, along with the following advice:
- Potable half-dozen to eight cups of h2o per twenty-four hours or plenty fluid to reach light-coloured urine.
- Reduce salt intake to not more than 5g per day.
- Aim for moderate protein intake, which works out to 1g of poly peptide to every 1kg of your weight. For instance, 1 to two eggs in the morning, 50g of salmon for lunch and 50g of ground beef for dinner.
