How excess oxalate formation affects our body?

Oxalate or oxalic acid is a compound which our body produces naturally and is found in our urinary tract along with calcium. Small amounts of calcium and oxalate do not produce any effect on our body but the problem starts when calcium and oxalate bind together and form hard mineral deposits in the kidney known as the calcium oxalate kidney stones. 

Low Oxalate Diet

Oxalate is not a required nutrient in the human body and therefore if we consume foods harbouring oxalate content, it travels through the digestive tract and gets passed out with stool or urine by binding with calcium. However, when excess oxalate level rises in the body and insufficient amounts of calcium are present, the surplus oxalate settles in the kidney forming kidney stones. 

The rise in oxalate levels can be caused due to various factors and some of the common causes are:

  1. Consuming a diet which is rich in Vitamin C. For the record, consuming vitamin C more than 1000mg per day has been shown to increase the oxalate levels in the body. 
  2. As side effects of certain medications especially antibiotics
  3. Having a history of kidney diseases and ailments
  4. Digestive disorders especially decorative gut health

The common symptoms observed in people suffering from kidney stones are

  1. Pain while urinating
  2. Blood in urine
  3. Sharp pain in the back and lower abdomen
  4. Vomiting and nausea

Most of the kidney stones undetected and that causes aggravation of the condition. Therefore, look out for the above-mentioned symptoms if you doubt having kidney stones and immediately consult your medical provider upon encountering any of the mentioned signs.
