Receiving weight loss surgery in Tijuana with our specialized bariatric surgeons has so many health benefits. Weight loss has positive effects on renal malfunction in patients in general and patients with primary kidney disease. However, some people who undergo weight loss surgery do experience kidney stones.

Bariatric surgery patients have a greater chance of developing kidney stones due to changes in urine and higher levels of oxalates (a salt or ester of oxalic acid).

This health problem that many face can easily be avoided through these helpful tips. To escape the discomfort and pain brought on by a kidney stone, follow the advice in this article.

What is a Kidney Stone, Exactly?

Kidney Stone after Bariatric SurgeryKidney stones (renal calculi) are a hard mass of minerals and acid salts that initially start off in the form of tiny crystals. When the crystals clump together over time, they form a stone.

Many times, kidney stones form to be so small that they pass right through the urinary tract unnoticed. However,  larger ones may become lodged in the ureters (the tubes connecting the kidneys and the bladder), blocking urinary flow and causing excruciating pain that is enough to make even the toughest cry.

Commonly, kidney stones are asymptomatic, but when they become symptomatic, they are painful. Symptoms consist of flank pain, nausea, blood in urine, and a fever. Many times, people end up in an emergency room for treatment.

Healthy Tips to Prevent Kidney Stones

1. Drinking Enough Water

Dehydration can lead to the build-up of minerals and kidney stones because there is no flow of water to push it through the urinary tract.

One good way to ensure you are getting adequate water is to calculate your ideal intake or speak with a professional who can recommend your ideal level based on your individual medical needs. Water uptake requirements can vary if you have had weight loss surgery such as gastric sleeve (VSG), so it is important that you listen to your nutritionist and doctors.

2. Take Vitamins Properly

When taking vitamins, it can be good to follow some guidelines on proper vitamin intake. Certain vitamins, such as B6 and Magnesium, help reduce the risk of kidney stones. Calcium and vitamin C, which are great for your health, have also been said to contribute to kidney stones. However, according to our source, this is not true.

We strongly recommend that those who have undergone gastric sleeve and gastric bypass in Tijuana stick to appropriate vitamin intake guidelines and follow them carefully.

3. Include These in Your Diet

Nurturing your kidneys with a well-balanced diet ensures their optimal function. Proper nutrition is a long-term investment in your health.

Breakdown by Type of Kidney Stone

There are 4 types of kidney stones: calcium, struvite, uric acid, and cystine. We discuss 3 of them here and their precautions.

1. Calcium Oxalate Stones

  • Reduce the amount of sodium in your diet; the recommendation is to have no more than 2300 mg per day. If you are prone to kidney stones associated with a high-sodium diet, the recommendation is to have less than 1500 mg of sodium per day.
  • Reduce your animal protein intake, such as meat, fish, and eggs. Protein needs are based on individual health requirements. A generally healthy range of protein is Your Ideal Healthy Body Weight divided by .8 to 1.2. This will give you the amount of protein in grams
  • Get enough calcium from food or take calcium supplements with food if you can’t get it all through your diet alone. Due to the decrease in digestive enzymes, we recommend that bariatric patients have 1500 mg of calcium daily with an added 2,000 units of vitamin D
  • Avoiding foods high in oxalate, such as the ones listed above

2. Calcium Phosphate Stones

  • Reduce the amount of sodium in your diet
  • Reduce your  animal protein intake
  • Get enough calcium from food or take calcium supplements with food if you can’t get it all through your diet alone

3. Uric Acid Stones

Uric acid stones are formed when the urinary uric acid concentration is increased.

  • Limit your animal protein intake.
  • Potassium citrate is also a good measure for preventing and treating this type of kidney stone.
