According to Oriental medicine, the feet are considered the body’s “second brain.” Not only do they bear the body’s weight, but they also contain numerous vital acupuncture points linked to internal organs. Because of this connection, observing changes in your feet can provide valuable insights into your overall health.
Despite their importance, feet are often neglected compared to other body parts such as the hair, ears, nose, and mouth. However, paying attention to specific signs in your feet can help detect potential health issues early. If you notice any of the following three symptoms, it could indicate damage to various organs in your body.
1. Swollen Feet: A Warning Sign for Heart, Kidney, or Liver Issues
Experts from Harvard Medical School (USA) warn that swollen or puffy feet are not always the result of minor injuries like sprains or muscle strains. Instead, they can be indicative of serious conditions such as heart failure, kidney disease, or cirrhosis.
- Heart Failure: When the heart struggles to pump blood effectively, fluid can accumulate in the legs, feet, and ankles. If swelling is accompanied by shortness of breath and fatigue, seek medical attention promptly.
- Liver Cirrhosis: In the late stages (F3 and F4) of cirrhosis, liver function declines, leading to changes in hormones and fluid regulation. This increases blood pressure in major vessels, causing swelling in the legs and fluid buildup in the abdomen (ascites).
- Kidney Disease: Damaged kidneys cannot efficiently remove excess waste and fluids, leading to swelling in the feet, ankles, and even the face.
2. Yellow Feet: A Potential Indicator of Liver, Gallbladder, or Pancreatic Diseases
Yellowish skin on the feet may be a sign of jaundice, which occurs when bilirubin—a substance produced by the liver—accumulates in the bloodstream. This could indicate:
- Cholangitis (bile duct inflammation)
- Gallstones
- Cirrhosis or liver cancer
- Pancreatic cancer
Jaundice is most noticeable in the feet, hands, eyes, and face. If you observe yellowing, consult a doctor for tests, including liver enzyme assessments, liver function tests, and imaging of the liver, bile ducts, and pancreas.
3. Pale White Toenails: A Sign of Kidney Damage
Kidney disease can disrupt the body’s blood circulation, leading to anemia. As a result, blood is redirected to more critical organs, causing the feet—being the lowest part of the body—to receive insufficient blood supply. This manifests as pale or white toenails and skin.
Additionally, if your nails appear thin, brittle, or deformed, it could be an early warning sign of kidney damage. Seeking medical evaluation is essential.
Signs of Healthy Feet and Internal Organs
When your internal organs function well, your feet will exhibit these characteristics:
- Rosy, Shiny Skin and Toenails: Traditional Chinese Medicine associates different foot colors with specific health conditions:
- Pinkish-red feet: Indicate good health
- Blue feet: Suggest poor circulation and cold extremities
- Yellow feet: May signal liver or gallbladder disorders, or anemia
- White or black feet: Can be linked to circulatory problems
If your toenails have white vertical lines, it may indicate weakened immunity, and incorporating more exercise and movement into your routine is advisable.
- Warm Feet:
- Cold feet may suggest poor circulation, an imbalance of yin and yang, or low immunity.
- Overheated feet may indicate a yin deficiency and excessive internal heat.
- Balanced feet (neither too cold nor too hot) are a sign of good overall health and longevity.
Boosting Health Through Foot Care
To enhance well-being, Traditional Chinese Medicine recommends soaking your feet in warm water daily. A popular saying states, “Soaking feet in warm water is better than medicine.” Spending just 15 minutes each day soaking your feet in water at approximately 40°C (104°F) can promote circulation, support organ health, and contribute to overall vitality.
