Reporter: Why is kidney disease dangerous, yet many people do not detect it early?
DR. Willie Ong:
“The kidneys can ‘withstand damage for a long time.’ When clear symptoms appear, their function has often already declined significantly.” Therefore, you should be extremely cautious of the following signs:
1. PROLONGED FATIGUE WITH NO CLEAR CAUSE
- When kidney function declines, toxins are not properly filtered and begin to accumulate in the blood → the body remains in a constant state of fatigue and low energy, and even rest does not help improve it.
👉 This is a sign that is very easy to overlook because many people think it is caused by stress or lack of sleep.
2. FREQUENT URINATION AT NIGHT
- The kidneys play a role in regulating urine output. When their function declines → the body loses control → frequent urination at night occurs, interrupting sleep.
👉 If it happens frequently → special attention is needed.
3. FOAMY OR ABNORMAL URINE
- Foamy urine may be related to protein leaking through the kidneys (a sign that the filtering function may have a problem).
👉 This is one of the early signs, but a very important one.
4. MILD SWELLING OF THE HANDS AND FEET
- When the kidneys cannot properly remove excess fluids → water is retained in the body → causing mild swelling in the legs, hands, or face.
👉 It may be mild at first, but if it continues, it can become more serious.
- The kidneys are located in the lower back area. When there is a problem → they may cause a dull ache or discomfort in the lower back, sometimes spreading to both sides of the waist.
👉 Easily mistaken for ordinary muscle or joint pain.
6. LOSS OF APPETITE – BODY FATIGUE
- The buildup of toxins in the body can affect the digestive system → causing loss of appetite, mild nausea, and physical weakness.
👉 This is a sign that usually appears when the condition has become more advanced.
DR. Willie Ong:
“👉 If you have two or more of these signs, your body may be sending an early warning signal.
👉 Recognizing them early and taking proactive care can help reduce risks later on.”
