The liver is a multitasking organ responsible for over 500 vital bodily functions, including filtering toxins, breaking down fats, and balancing hormones. Foot changes can be caused by tight shoes, standing for long hours, injuries, and other factors. However, sometimes certain symptoms may reflect deeper internal issues, especially related to liver health. Here are 6 signs that may appear on your feet if your liver isn't functioning properly.
Red or brown spots on the feet:
Red or brown spots on the legs may look like insect bites or bruises. In some cases, they may be petechiae, or signs of blood leaking under the skin. Liver damage can affect blood clotting due to decreased production of clotting proteins. This makes small capillaries, especially in the lower legs where gravity plays a role, more prone to rupture. Another cause is chronic venous insufficiency, sometimes associated with cirrhosis, which can cause blood to pool in the lower extremities.
Spider veins on ankles and feet:
Spider veins are small, web-like blood vessels visible just beneath the skin's surface, often on the feet and ankles. In individuals with cirrhosis, the disrupted estrogen metabolism can cause blood vessels to dilate, leading to spider veins. This is not just a cosmetic issue, but also indicates blood vessel abnormalities and liver dysfunction.
Cracked heels:
Cracked heels are mainly caused by dry skin or poor foot care. Liver damage can affect the body's ability to absorb fat-soluble vitamins such as A, D, E, and K. Vitamin A deficiency, in particular, can lead to thick, dry, cracked skin, typically on the heels.
Burning or tingling feet:
A burning sensation in the soles of the feet at night is not always related to fatigue or overexertion. Advanced liver damage, especially alcoholic liver disease, can lead to peripheral neuropathy. This nerve damage causes a burning or tingling sensation in the feet. High blood ammonia levels due to poor liver detoxification can also irritate nerves, leading to this symptom.
Foot odor:
Foot odor is not only caused by bacteria and sweat, but can also stem from impaired liver function. When the liver doesn't process and eliminate toxins properly, some of these waste products can be released through sweat glands, including those on the feet. Combined with changes in the body's metabolism and hormones, this can lead to unusual foot odor that may not improve with regular hygiene.
Fungal nail infections:
Thick, yellow, or easily cracked or broken toenails are common in people with fungal infections. Most cases are caused by tight shoes or exposure to unsanitary environments, but liver health can also be a factor. Liver damage can weaken the immune system over time. With a slower immune response, fungal microorganisms can easily invade and grow, especially in the dark, moist environment around toenails. This is a sign that the body may be losing some of its natural defenses.
