Gravity: Blood and fluids naturally tend to accumulate more easily in the lower limbs.
Circulation: The liver plays a fundamental role in protein synthesis and in regulating pressure within the portal vein. When liver function decreases, blood flow in the legs can be affected.
Metabolism: The liver produces proteins—especially albumin—that help keep fluids inside the blood vessels. When albumin levels decrease, fluid can leak into the surrounding tissues, causing swelling.
Detoxification: When the liver cannot properly filter toxins, skin reactions such as itching or changes in skin color may occur.
5 Signs in the Legs That May Indicate Liver Problems
1. Swelling (Thighs, Ankles, or Feet)
What it looks like:
Shoes become tight, sock marks remain visible, and pressing on the skin leaves an indentation for several seconds. Swelling usually becomes worse in the evening.
Connection to the liver:
Damaged liver cells produce less albumin, disrupting fluid balance and causing edema. Portal hypertension (increased pressure in the portal vein) can also interfere with normal venous return, contributing to swelling.
2. “Spider Veins” (Telangiectasias)
