Benefits of weight loss surgery are lower blood pressure, remission of diabetes, decreased risk of heart disease, lower blood cholesterol level, etc. as we all know, every benefit has a potential risk. A recent article in the Journal of Urology looked at the risk of kidney stones and gastric bypass surgery.
4,639 patients who underwent bypass surgery and 4,369 obese patients in a control group who didn’t have bariatric surgery were followed for four years. Of those, 4.6 percent of the control group developed kidney stones versus 7.7 percent of the bypass surgery group developed stones. This is a slight increase risk of developing kidney stones after bariatric weight loss surgery.
Prevention of kidney stones requires staying hydrated by drinking at least 64 ounces of fluid each day. This will prevent concentrating your urine which will decrease risk of kidney stones. If possible learn what type of kidney stones that you may be at risk of developing –calcium based kidney stone may require you to watch your intake of dairy products or if it is oxalate based may require you to limit your intake of dark green vegetables (spinach, kale,) and herbal teas. Consult with your primary care doctor if you suspect you are at risk of kidney stones.
