The kidneys function as the body’s filters, silently supporting overall health. Yet many people unknowingly damage them over time. By recognizing the early signs of kidney disease and adopting simple dietary and massage remedies, you can help prevent kidney failure and reduce your chances of needing dialysis.

Some may consider the kidneys to be “silent” because the early symptoms of kidney disease are typically subtle or go unnoticed. By the time symptoms appear, the condition has often progressed to an advanced stage. In 2020, the United States had the second-highest dialysis rate in the world, following Taiwan, according to the United States Renal Data System.

Early Signs of Kidney Disease

On the “She Health” program, Lin Yuan-Chuan, director of the Lin Yuan-Chuan Chinese Medicine Clinic in Taiwan, shared key warning signs of kidney disease. These include the following:
  • Foamy urine: Persistent or excessive foam in the urine may signal kidney problems.
  • Edema (swelling): Generalized swelling, particularly around the eyelids, face, and limbs, can indicate kidney damage.
  • High blood pressure: Studies show that most people with chronic kidney disease also have hypertension (high blood pressure). Hypertension can contribute to chronic kidney disease, and chronic kidney disease can worsen hypertension, creating a harmful cycle.
  • Anemia: Research suggests that anemia becomes more common in advanced chronic kidney disease. A sudden onset of anemia in someone with no prior history may indicate declining kidney functions and reduced erythropoietin, the hormone responsible for stimulating red blood cell production.
  • Fatigue: Frequent tiredness or exhaustion, even without significant physical exertion, may signal declining kidney function.
Lin recommends seeking prompt medical attention if any of these symptoms occur and undergoing diagnostic testing for an accurate evaluation.

Common Causes of Kidney Damage

Taiwan has the highest dialysis rate in the world, mainly due to dietary habits, Lin said. He highlighted several common factors that can harm kidney health.

Plasticizers

Plasticizers in food pose serious health risks. A cohort study found that exposure to plasticizers may increase the risk of kidney damage, malignant tumors, metabolic syndrome, and cardiovascular disease. A survey also linked the frequent use of plastic tableware or microwaving food covered in plastic wrap to higher levels of phthalate metabolites (plasticizer breakdown products) in urine.

Heavy Metals in Seafood

Studies have shown that heavy metals like arsenic, cadmium, lead, and mercury can damage the kidneys. Larger fish, such as tuna, accumulate higher levels of heavy metals, increasing the risk of kidney harm in those who eat them. Opting for smaller fish species can reduce exposure, as they generally contain lower heavy metal levels.

Improper Medication Use

Overuse of both Western and traditional Chinese medicine (TCM) can harm the kidneys. A review found that nonsteroidal anti-inflammatory drugs (NSAIDs), such as acetylsalicylic acid (aspirin), may increase the risk of acute kidney injury, particularly in older patients and those with chronic illnesses.
