Kidney stones can provide considerable pain during urination, but also in everyday life. When the urine kidney stones sufferer or damage the kidney itself, can even blood when urinating perceptible.
Questions about kidney stones, and especially how you can avoid them.
A small kidney stone is a stone formed by the agglomeration of insoluble crystals in the urine. The main substances are such a stone can form calcium, uric acid and oxalates.
The most frequent are the kidney stones of calcium oxalate and phosphate: are they good for about 80% of all kidney stones. The second are formed of uric acid kidney stones, and stones caused by an infection. Finally, there is a rather rare, inherited condition where kidney stones are from the amino acid cystine.
Who is at risk of kidney stones?
An estimated 5 to 10% of the population suffers from kidney stones. They are 2 to 3 times more common in men than in women, especially in young and slightly older men. But they are not really tied to a certain age.
What symptoms may indicate kidney stones? The accumulation of urine and the dilation of the upper urinary tract stones cause severe pain in the back, along the side where the kidney stone is. This pain radiates to the flank and to the genitals. The pain may appear very suddenly, or is contrary it slowly settle. These complaints are typical of a renal crisis, which also striking that the patient unsuccessfully looking for a position that brings a little relief.
There are other symptoms with renal crisis may be associated, such as pain when urinating, the presence of blood in the urine, a marked reduction of urine, nausea, vomiting. These complaints significantly from when the kidney stone is ejected.
What are the causes? The main cause of kidney stones is an insufficient fluid intake. The less we drink our urine is more concentrated and easier to form kidney stones.
The fact that most stones contain calcium, explains why calcium rich diet used as the main culprit was considered and that a kidney stone patient was put on a diet.
Increased calcium content in the urine, the formation of kidney stones actually work in hand. But contrary to popular belief, but usually not due to a too high intake of dietary calcium. Many other factors, unrelated to calcium-rich food to have, the excretion of urinary calcium influence. We think such an applicators of high salt, protein and carbohydrates and hormone that the kidney uptake of calcium by the kidneys regulates.
And even if the urine contains too much calcium, it does not mean that there will be a kidney stone formed. In the urine certain substances are also going to stone formation. One of the first is, citric acid (including present in citrus fruits).
Recently, the tendency is even more and more of the calcium from the diet can inhibit formation of kidney stones. That calcium is in fact a connection to the intestinal oxalate, another substance responsible for kidney stones. Oxalates are including in tea, cola drinks, white wine, rhubarb, strawberries, raspberries, tomatoes, chocolate, nuts, beets, spinach ... These nutrients were used with the finger pointed. But probably not so much an excessive consumption of foods responsible for the formation of kidney stones, but the combination of too little calcium. Studies have shown that kidney stone patients are not eating more oxalates than normal people, but too little calcium products.
An excessive amount of uric acid in the urine can also cause the formation of kidney stones. This uric acid is derived from the pureness present in certain foods such as meat, seafood, organ meat, lentils, poultry ... Furthermore; some people naturally create too much uric acid.
Stress can cause kidney stones? Surely not: the origin of kidney stones is always dry, and not psychological. But stress it can indirectly contribute to the formation of kidney stones, in that very busy people often drink too little and much eat foods.
If not quickly removed a kidney stone, whether or not spontaneous, it may smooth functioning of the kidney and even prevent irreversible damage. When the jade is also associated with a urinary tract infection, the risk of kidney injury even more.
What preventive treatments are available? * The first, very simple and effective measure is more drinking. It is recommended that every hour to drink a glass of water, representing about 1 to 1.5 liters of water per day. This allows more than 24 hours per liter of water 2 hours to urinate.
- Contrary to popular belief, it is usually unwise to reduce calcium intake. More than that calcium may reduce the risk of kidney stones is increasing, because of the increased oxalate in the urine.
