Gastric Sleeve and Kidney Problems

Roux-en Y is the most common gastric bypass. In this procedure, a small and upper section of the stomach is separated by staples or bands to create a small pouch. This procedure would limit the amount of food the patient could consume. It could hold about an ounce of food but can expand to about 4 to 8 ounces of food after a few months. A Y-shaped section of the small intestines is attached to the stomach. This new shape would allow the food to bypass the upper portion of the intestines.

There are many benefits brought by gastric bypass surgery. Individuals who have undergone the procedure are said to reduce their weight with an average of 50 to 60%. Some would lose about 80% of their body weight two years after the surgery. The procedure can reduce diabetes, hypertension, high cholesterol levels, and even cancer risks. However, there are also downsides with this surgery.

Gastric bypass surgery is an effective way of losing weight and obesity-related health risks. However, there are studies showing concern about nephrolithiasis or the formation of kidney stones among those who have undergone gastric bypass surgery. According to a paper presented in the 39th Annual Meeting and Scientific Exposition of American Society of Nephrology, gastric bypass surgery increased the possibility of kidney stones.

This paper was not the first time that this kind of risk is identified with almost similar operations. In 1979, the Food and Drug administration had the jejunal ileal bypass under moratorium. This thought was because patients who had the procedure developed kidney stones five years after surgery.

Currently, studies are showing that those who have undergone gastric bypass surgery would experience changes in the chemical composition of their urine. These changes eventually can lead to the formation of kidney stones. After the gastric bypass surgery, the level of oxalate increased. This chemical, when bound with calcium, can cause an increase in kidney stones.

Another cause could be the production of low levels of citrate. Citrate dissolves crystals, which can cause kidney stones. Low citrate levels and high levels, a combination that leads to an increase of calcium oxalate supersaturation. This increases or a strong factor or risk for having kidney stones. Other chemicals that also contribute to kidney stone formation like uric acid and potassium remain unchanged before and after the surgery.

A study conducted by Mayo Clinic showed that those who have undergone the procedure for the last six months had not developed this kind of chemical change. This condition could be avoided, or the risk is reduced by undergoing some dietary changes. Doctors would recommend an increase in the intake of fluids, low-protein, and low-salt diet, and a regular calcium diet.
