Kidney Pain After Eating Protein Or Sugar: What Kidney Pain Is Like

The two kidneys in human being are important organs which has various functions to perform. It is a part of excretory system of the body. Both kidneys are responsible for processing the metabolic waste products and excess of water in the form of urine. The blood is continuously cycled through the kidney to remove nitrogenous waste and other chemicals.

All these waste products get dissolved in urine and are passed out through urine. When urine is saturated with excess amount of waste material, there is a risk for formation of kidney stones. These stones give rise to pain in kidney and other urinary organs when they pass through it.

Causes Of Kidney Pain After Eating Protein

Now the question arises why eating protein causes kidney pain. To answer this, we must know certain basic human physiology. When we eat food that contains protein, it gets digested and metabolized and leaves behind its metabolic waste. Protein contains a substance called purines. When we eat protein containing food, it breaks down the purines into uric acid; it is a metabolic nitrogenous waste of protein.

It gets dissolved in the blood and passes through the kidney. Kidney filters uric acid from the blood and eliminates it through urine.

Now if your diet contains very high amount of protein, or you are taking very high dose of protein supplement your body may not be able to eliminate all the uric acid. This extra amount of uric acid circulating in blood may form into uric acid crystals and get deposited at various sites such as in joints and in the kidneys. In kidneys they form uric acid stones.

Generally, a small kidney stone may not give rise to kidney pain until it starts to move into the ureter. Ureter is a tube which connects kidney to urinary bladder. The urine passes from kidney to bladder through this tube. Together with pain, there may be other symptoms such as blood in urine, fever, vomiting, nausea etc.
