The Silent Cry of Your Kidneys: 7 Warning Signs You Should Never Ignore

The kidneys are like the most silent model workers in our bodies, rarely shouting pain even when they are so tired that they are on the verge of collapse. As one of the most important detoxifying organs of the human body, it filters about 180 liters of blood per day, which is equivalent to the amount of 10 barrels of water! But it is shocking that this industrious organ should be devoid of pain-sensing nerves, often scarred when it signals us for help.

The “silent cry” of the kidneys: these symptoms are destroying your health

I’ve seen too many patients and didn’t realize something was wrong with the kidneys until late in uremia. Kidney disease is like lurking agents, silently undermining our health lines. By the time it finally can’t help but signal, the best time for treatment is often missed.

There is no more disturbing signal than a change in urine. Imagine when you find that your urine smells like pungent ammonia, like a bottle opened in a chemistry lab; or it takes on an eerie soy sauce color, as if strong tea had been poured in. None of this is accidental, but rather a red cautionary flag the kidneys are desperately waving.

Frequent nocturia is a clear warning from the kidneys. If you have to get up more than 3 times a night, just as on time as if you had an alarm set, it is likely that the kidney concentration function is declining. One of my patients once mocked himself by saying, “My bladder is more punctual than my alarm clock”, and as a result, the examination revealed that kidney function had dropped by 40%.

Oedema: A “water prison” crisis in the body

When the kidneys have problems draining, the body becomes a leaky reservoir. The most obvious is when you wake up in the morning, your eyelids are swollen like you’ve been crying all night; or when you press a hole in your calf, the rebound speed is as slow as an old memory foam. This edema is different from the occasional puffiness, it persists like invisible shackles that bind the body.

I remember a middle-aged male patient who came to see a doctor because his shoes suddenly couldn’t fit in. The examination revealed that his indicators of kidney function were already severely abnormal, and that the cause of all this was hypertensive, which had been neglected for a long time. He said, “I thought it was just getting older and gaining weight, and I didn’t expect it was the kidneys calling for help.”

The “Golden Six Hours” to Save the Kidneys

Protecting the kidneys does not require expensive health products, the key lies in daily detail control. I summarized the “Golden Six Hours” rule: drinking a glass of water every 2-3 hours is like giving your kidneys a gentle rinse. However, be aware that drinking water is not a competition, and drinking too much water will increase the burden on the kidneys.

Salt control is a top priority. China’s per capita salt intake is as high as 10.5 g/day, more than double the amount recommended by the World Health Organization! Imagine that the kidneys process so much salt every day, like having a worker work continuous overtime and never rest. Salt-limiting scoops are recommended to make salt control visual.

Top 5 Cognitive “Landmines” About the Kidney

In the outpatient clinic, I found that there were too many misconceptions about the kidneys. There is nothing more ridiculous than the “form to form” theory —— Eating animal kidneys can nourish the kidneys. In practice, animals have extremely high levels of kidney cholesterol, and excessive consumption can instead increase the burden on the kidneys.

Another common myth is blaming the kidneys for all low back pain. In practice, 90% of low back pain stems from musculoskeletal problems. True kidney pain is usually on either side of the ribs below and is often accompanied by other urinary symptoms. A patient took kidney-tonifying medicine for half a year because of low back pain, and it turned out that it was just a herniated disc, which was ridiculous.

Renal examination: “Annual security check” that cannot be ignored

I strongly recommend doing routine urine and kidney function tests at least once a year, which is like giving your kidneys a full “security check”. In particular, patients with hypertension and diabetes should be examined every 3-6 months. Early kidney disease often has no obvious symptoms, and by the time discomfort occurs, more than half of the kidney function may have been lost.

I was impressed by an entrepreneurial patient who spends tens of thousands of dollars every year on high-end physical examinations but never does the most basic urine routine. It was not until the onset of severe anaemia that it was discovered that it was terminal uremia. He said, “I checked my whole body and forgot to check the most important filters.” This regret is not uncommon clinically.

Kidney health does not happen overnight, but is guarded over time. From today, listen to the subtle changes in your body and give this silent organ a little more care. Remember that prevention is always simpler than cure, and early intervention is more effective than late rescue. Your kidney may not speak, but it deserves to be treated with tenderness.
