Kidney Stones – Causes and Symptoms

In earlier post, we have discussed about Kidney Stones – Sizes and Types. In this post, we are gonna see the causes and symptoms of Kidney Stones,

Risk factors for kidney stones

Dehydration is a major risk factor for kidney stone formation.  Kidney can make less than one liter of urine per day. This is why kidney stones are common in premature infants who have kidney problems. Kidney stones are most likely to occur between the ages of 20 and 40.


Different factors can increase your risk of developing a stone.

Other risk factors are,

  • Obesity
  • Hyperparathyroidism
  • High-protein, salt or glucose diet
  • Gastric bypass surgery
  • Inflammatory bowel diseases that increase calcium absorption
  • Taking medications such as diuretics, anti-seizure drugs and calcium-based antacids

Symptoms of Kidney Stones

Kidney stones don’t always cause symptoms. When they’re small, they may pass on their own without pain. However, large stone may block urine flow, which can cause a number of painful symptoms that can be severe. This can happen when a kidney stone becomes stuck in the ureters, which is the tube that connects your bladder to your kidneys.


  • Severe pain in the back, belly or groin
  • Frequent or painful urination
  • Blood in the urine
  • Nausea and vomiting
  • Discolored or foul-smelling urine
  • Chills
  • Fever
  • Urinating small amounts of urine

Small stones may pass without causing any symptoms. Blood present in the urine due to kidney stones can also cause urine to appear brown, pink or red.
