You can be thin, eat clean, hit your steps, and still have the kind of belly fat that destroys your kidneys. A 2023 PLOS One cohort of 11,050 adults followed for nearly 6 years found that the highest visceral fat group had 7.5 times the risk of developing chronic kidney disease, and the strongest effect was in normal-weight people. BMI lies. The waist tells the truth. This article walks through why subcutaneous and visceral fat are biologically different, the three documented

Your creatinine test may be lying to you. By the time creatinine clearly rises on a lab report, you may have already lost a third or more of your kidney function. The 2021 guidance from the National Kidney Foundation and American Society of Nephrology recommended a second test, cystatin C, as a confirmatory marker for specific patients. Four years later, most labs still default to creatinine alone. This article walks through why creatinine is actually a muscle test, what cyst

There is a new shot hitting bariatric-surgery weight loss numbers without the surgery. In the phase 3 TRIUMPH-1 trial, the highest dose produced an average of 28.3 percent body weight loss at 80 weeks. That is almost twice the weight loss we saw in semaglutide's pivotal obesity trial. I am a nephrologist and an obesity medicine specialist, and I have been waiting on this data for two years. The phase 3 numbers finally dropped, and they are not subtle. Below, I walk through ex

If you have kidney disease, the smoothie your cardiologist told you to drink could be the single biggest reason your numbers are getting worse. The same foods you ate for 30 years without a problem can become the problem the day your kidney function drops. The rules change once your kidneys do, and most of the wellness advice on the internet was not written for you. Five foods sold as healthy actively harm two groups of patients: anyone with chronic kidney disease at any stag

Three out of four kidney stones cannot be dissolved by anything you drink. Not lemon water. Not apple cider vinegar. Not any cleanse on the internet. Only one type can, and for the most common stone of all (calcium oxalate, 75 to 80 percent of every stone), the standard primary-care advice to cut dairy is the move that almost guarantees the next stone. The American Urological Association settled this 20 years ago. Primary care has not caught up. This is for anyone who has bee

People who live to 100 share one quiet pattern that nobody talks about. It is not their cholesterol. It is not their gym routine. It shows up as a single number on a routine blood test, and 9 out of 10 people with abnormal kidney function have no idea theirs is wrong. This is the centenarian kidney pattern researchers have actually found, why your kidneys are master chemical regulators rather than simple filters, and the four daily levers that protect both kidneys and healths

You probably have at least three of these in your bathroom cabinet right now. They cost $10. They feel harmless. And in the wrong person, taken often enough, they can damage kidneys for years without a single warning sign. This is a walkthrough of the five drug classes a nephrologist sees most often as the cause of preventable kidney injury, the exact mechanism behind each, and the 30-second pharmacist conversation that can change a kidney trajectory. This is for anyone who r

A 3,533-person trial of semaglutide in type 2 diabetes and chronic kidney disease was stopped early because the kidney and survival benefits were so clear that leaving anyone on placebo was no longer ethical. Patients on semaglutide saw a 24 percent reduction in major kidney events and a 20 percent reduction in death from any cause across three and a half years. The FDA expanded the approval, and the standard of care changed. This is for anyone with type 2 diabetes whose kidn

Foamy urine has a 1 in 5 chance of meaning your kidneys are leaking albumin into the toilet. The leak often shows up years before a standard blood test looks abnormal, and the test that catches it costs about $30 at most labs. Here is how to tell the foam that matters from the foam that does not. This is for anyone who has noticed persistent foam in the toilet and been told to “keep an eye on it.” Why Foamy Urine Sometimes Matters Most foamy urine is benign. A fast urine stre
