The kidney stone is made up of minerals that form inside your kidneys. They can be as small as sugar crystal or as large as golf balls. These stones may stay in your kidneys or are passed out in urine. If a stone is too large, it gets stuck in the urinary tract to cause intense pain and may lead to blockage resulting in kidney damage if not removed.
Kidney stone usually does not cause any pain or symptoms until it moves around or gets stuck in the urinary tract
Severe abdomen or back pain
Feeling sick, nausea and vomiting
Blood in the urine.
There are different types of stones (most common are made of calcium phosphate and oxalate). Several factors may increase your risk of developing kidney stones such as
Family history of kidney stones
Obesity and being overweight
Taking diet high in protein, sodium (salt) and sugar
Medical conditions such as high uric acid, hyperparathyroidism, and inflammatory bowel disease
Keep yourself well hydrated and drink at least more than 2 liters of water a day unless your doctor has advised you not to drink high volume of water due to other medical conditions such as heart failure
Avoid food high in salt and animal protein
If you have history of kidney stone, avoid food rich in oxalates such as spinach, French fries, and nuts
If you have recurrent kidney stones, your doctor may prescribe some medicines to avoid their formation such as Potassium Citrate.
If you have symptoms, see your doctor without delay for further tests and imaging to rule out any blockage and avoid kidney damage.
Your doctor will likely prescribe pain relievers and other medicines to help you passing kidney stones
If pain or blockage is not relieved, you should see a urologist (kidney surgeon) as you may need surgical removal.
