why do you get nausea with kidney stones

Kidney stones are hard collections of salt and minerals often made up of calcium or uric acid. They form inside the
and can travel to other parts of the urinary tract. Stones vary in size. Some are as small as the period at the end of this sentence в a fraction of an inch. Others can grow to a few inches across. Some kidney stones can become so large they take up the entire kidney. A kidney stone forms when too much of certain minerals in your body accumulate in your urine. When you arenвt well hydrated, your urine becomes more concentrated with higher levels of certain minerals. When mineral levels are higher, itвs more likely that a kidney stone will form. About 1 out of every 11 people in the United States will get a kidney stone. Stones are more common in men, people who are obese, and those who have ( ). Smaller kidney stones that remain in the kidney often donвt cause any symptoms. You might not notice anything is amiss until the stone moves into your в the tube that urine travels through to get from your kidney to your bladder. Kidney stones are typically very painful. Most stones will pass on their own without treatment. However, you may need a procedure to or remove stones that donвt pass. Here are eight signs and symptoms that you may have. Kidney stones (renal lithiasis, nephrolithiasis) are hard deposits made of minerals and salts that form inside your kidneys. Kidney stones have many causes and can affect any part of your urinary tract from your kidneys to your bladder.


Often, stones form when the urine becomes concentrated, allowing minerals to crystallize and stick together. Passing kidney stones can be quite painful, but the stones usually cause no permanent damage if they're recognized in a timely fashion. Depending on your situation, you may need nothing more than to take pain medication and drink lots of water to pass a kidney stone. In other instances for example, if stones become lodged in the urinary tract, are associated with a urinary infection or cause complications surgery may be needed. Your doctor may recommend preventive treatment to reduce your risk of recurrent kidney stones if you're at increased risk of developing them again. A kidney stone may not cause symptoms until it moves around within your kidney or passes into your ureter Б the tube connecting the kidney and bladder. At that point, you may experience these signs and symptoms: Severe pain in the side and back, below the ribs Pink, red or brown urine Pain caused by a kidney stone may change for instance, shifting to a different location or increasing in intensity as the stone moves through your urinary tract. Make an appointment with your doctor if you have any signs and symptoms that worry you. Kidney stones often have no definite, single cause, although several factors may increase your risk. Kidney stones form when your urine contains more crystal-forming substances such as calcium, oxalate and uric acid than the fluid in your urine can dilute. At the same time, your urine may lack substances that prevent crystals from sticking together, creating an ideal environment for kidney stones to form.


Knowing the type of kidney stone helps determine the cause and may give clues on how to reduce your risk of getting more kidney stones. If possible, try to save your kidney stone if you pass one so that you can bring it to your doctor for analysis. Calcium stones. Most kidney stones are calcium stones, usually in the form of calcium oxalate. Oxalate is a naturally occurring substance found in food and is also made daily by your liver. Some fruits and vegetables, as well as nuts and chocolate, have high oxalate content. Dietary factors, high doses of vitamin D, intestinal bypass surgery and several metabolic disorders can increase the concentration of calcium or oxalate in urine. Calcium stones may also occur in the form of calcium phosphate. This type of stone is more common in metabolic conditions, such as renal tubular acidosis. It may also be associated with certain migraine headaches or with taking certain seizure medications, such as topiramate (Topamax). Struvite stones. Struvite stones form in response to an infection, such as a urinary tract infection. These stones can grow quickly and become quite large, sometimes with few symptoms or little warning. Uric acid stones. Uric acid stones can form in people who don't drink enough fluids or who lose too much fluid, those who eat a high-protein diet, and those who have gout. Certain genetic factors also may increase your risk of uric acid stones.


Cystine stones. These stones form in people with a hereditary disorder that causes the kidneys to excrete too much of certain amino acids (cystinuria). Family or personal history. If someone in your family has kidney stones, you're more likely to develop stones, too. And if you've already had one or more kidney stones, you're at increased risk of developing another. Dehydration. Not drinking enough water each day can increase your risk of kidney stones. People who live in warm climates and those who sweat a lot may be at higher risk than others. Certain diets. Eating a diet that's high in protein, sodium (salt) and sugar may increase your risk of some types of kidney stones. This is especially true with a high-sodium diet. Too much salt in your diet increases the amount of calcium your kidneys must filter and significantly increases your risk of kidney stones. Being obese. High body mass index (BMI), large waist size and weight gain have been linked to an increased risk of kidney stones. Digestive diseases and surgery. Gastric bypass surgery, inflammatory bowel disease or chronic diarrhea can cause changes in the digestive process that affect your absorption of calcium and water, increasing the levels of stone-forming substances in your urine. Other medical conditions. Diseases and conditions that may increase your risk of kidney stones include renal tubular acidosis, cystinuria, hyperparathyroidism, certain medications and some urinary tract infections.
