[Health Snack] Doctor shares the critical lifestyle changes needed to prevent toxic waste buildup and preserve renal health
The kidneys serve as the body’s vital, built-in filtration system, regulating fluid balance and filtering out waste. While many people take kidney function for granted, a decline in these organs can lead to severe health complications. Waste accumulation can cause uremia, blood pressure can spike, and a drop in red blood cell production can trigger anemia
To help prevent these issues, radiologist Lee Won-kyung recently shared crucial advice in a video titled “Seven Lifestyle Habits That Save Your Kidneys” on the YouTube channel “Doctor Who Finds Cancer.”
Hydration and Sodium Control
According to Lee, the most critical habit is maintaining proper hydration. “Many people neglect drinking water because they are busy or find it inconvenient,” Lee said. “It is essential to break the habit of enduring thirst just to keep working or studying.”
He explained that dehydration forces blood vessels to work harder to eliminate waste. However, Lee noted that proper hydration does not mean consuming excessive amounts indiscriminately, and emphasized that coffee or other beverages cannot substitute for pure water
Controlling sodium intake is equally vital. A high-salt diet impairs the kidneys’ ability to maintain electrolyte balance. When this balance is disrupted, blood pressure rises and potassium can accumulate in the body, significantly increasing the risk of cardiac arrhythmia
Managing Painkillers and Supplements
Lee also warned against the frequent use of over-the-counter pain relievers. “Painkillers can constrict the blood vessels in the kidneys,” Lee explained. “Excessive use disrupts renal blood flow, causing a decline in kidney function.” He noted, however, that taking these medications within the recommended daily allowance is generally safe for healthy adults
Dietary supplements pose another potential risk if overused. While many consider them daily essentials, taking more than 10 different supplements a day can place a toxic burden on the kidneys. Lee advised narrowing consumption down to just one or two truly necessary supplements
Sleep, Diet, and Lifestyle Risks
Inadequate sleep is another major contributor to deteriorating kidney health. “Chronic sleep deprivation increases the risk of systemic inflammation,” Lee stated. “This elevates blood pressure and keeps the body in a constant state of tension, preventing the kidneys from functioning properly.”
Additionally, Lee urged caution regarding high-fructose corn syrup, a primary driver of obesity and elevated blood sugar levels. “Frequently consuming products high in high-fructose corn syrup, such as soda, can deal a critical blow to your kidneys,” Lee warned. “We should not sacrifice long-term health for momentary sweetness.”
