Recognizing and Preventing Kidney Disease: From Early Signs to Advanced Stages

This podcast episode, hosted by Dr. Ekberg, a holistic doctor and former Olympic decathlete, delves into the critical importance of kidney health, emphasizing early detection and prevention of chronic kidney disease (CKD). Dr. Ekberg highlights that the kidneys are not merely filters but also sophisticated sensors that regulate pH, oxygen levels, and produce vital hormones like erythropoietin (EPO). He explains the complex process of selective reabsorption, where kidneys filter over 200 liters of fluid daily but reabsorb 99% of water and sodium, 100% of glucose and amino acids, while efficiently eliminating waste products like creatinine. The episode critiques common approaches that simply list symptoms, instead focusing on understanding the progression of CKD through its five stages and the specific markers and symptoms associated with each.

The core diagnostic marker discussed is the estimated Glomerular Filtration Rate (eGFR), which indicates how well the kidneys are functioning. Dr. Ekberg meticulously outlines the five stages of CKD: Stage 1 (normal eGFR but potential damage), Stage 2 (reduced eGFR 60-89 ml/min, often asymptomatic but warrants attention), Stage 3 (significant reduction 30-59 ml/min, where symptoms like high blood pressure, anemia, bone disease, and edema begin to appear), Stage 4 (severe reduction 15-29 ml/min, with intensified symptoms and preparation for dialysis/transplant), and Stage 5 (near complete failure <15 ml/min, leading to extreme symptoms like pulmonary edema, ammonia breath, and severe electrolyte imbalances).

Dr. Ekberg provides practical insights into recognizing early signs, such as subtle changes in urination (color, smell, frequency, appearance, cloudiness, foam, protein, bacteria) even in Stage 1. He elaborates on the physiological mechanisms behind symptoms in later stages, explaining how kidney damage leads to anemia (due to insufficient EPO), osteoporosis (due to phosphate-calcium imbalance), and edema (due to albumin loss). He also differentiates between referred back pain and the sharp, unyielding pain of a kidney stone, offering a key distinction for listeners.

Crucially, the podcast emphasizes that the most effective time to intervene is long before any overt CKD symptoms manifest. Dr. Ekberg identifies insulin resistance as the earliest and most significant indicator of potential kidney issues, linking it directly to Type 2 Diabetes, which he states is the number one cause of kidney failure, blindness, and amputations due to its destructive impact on tiny blood vessels. The overarching recommendation is to learn about and actively reverse insulin resistance as the primary strategy for protecting kidney health and preventing the progression to severe kidney disease, dialysis, or transplant.

If it were to fail you would be really sick within a couple of days and you would probably be dead within a week.

The kidney is often described as a filter and while that is correct it does so much more. It is a sensor.

It reabsorbs 99% of all the water and all the sodium so it's very good at getting rid of the extra sodium that it doesn't want.

The whole point of this is that the eGFR is a pretty good way to measure how your kidneys are working and how to give you little hints long long before you have symptoms.

Now here's the interesting thing that I don't understand is this is called normal on the blood work and even though it's called stage 2 chronic kidney disease this range is considered normal.

So the body makes a hormone that is going to pull calcium from the bone to balance that phosphate. So that's how kidney disease can actually cause osteoporosis.

One way that you can distinguish this from other severe back pain is that a kidney stone typically is not gonna ease up no matter what you put your body position in.

You're almost drowning in your own lungs because this fluid that's leaking out into the tissues from edema from a lack of albumin now it can start filling up your lungs known as chronic obstructive pulmonary disease.

The earliest it can tell it's called insulin resistance and if you watch some videos on this channel you probably recognize that but why is it related to the kidney because type 2 diabetes is the number one cause of kidney failure.

If you really want to take care of your kidneys then start learning about insulin resistance and reverse that.
