It can be seen that the feet are the foundation of health, but they are the lowest organs so they are often less concerned than hair, ears, nose, mouth... Right now, you should check your feet, if you see the 3 signs below, it shows that many organs in your body are damaged.

1. Swollen feet: Heart failure, kidney failure, cirrhosis

According to health experts from Harvard Medical School (USA), when your feet are swollen or puffy, many people will think they are a sign of sprains, muscle strains, or venous insufficiency. But in fact, it can also be a sign of heart failure or kidney failure, cirrhosis.

If your heart is damaged, one or both of the lower chambers of the heart (left ventricle and right ventricle) will lose the ability to pump blood effectively. At the same time, the ability to return blood from the organs to the heart is also reduced, causing blood to stagnate in the veins and eventually leading to edema in the legs, feet, and ankles... If swollen feet are accompanied by signs of shortness of breath and fatigue, you should see a heart doctor as soon as possible.

If swollen feet are accompanied by signs of shortness of breath and fatigue, you should see a heart doctor as soon as possible.

Leg swelling is also common in patients with cirrhosis in the late stages F3 and F4. When liver function declines, hormones and fluid regulators change accordingly. This increases pressure in the large blood vessels, causing blood to be carried from the spleen and intestines to suddenly switch to the pancreas and liver. This results in ascites in the abdomen and leg swelling.

In addition, leg swelling is also a sign of kidney failure. Damaged kidneys cannot remove excess waste, so fluid accumulates in the body, causing swelling in the legs, ankles, feet, face, etc.

2. Yellow feet: Liver, gallbladder, and pancreatic diseases

Yellow skin on the feet can be a sign of jaundice. But more seriously, it can be a sign that you have cholangitis, gallstones, cirrhosis, liver cancer, pancreatic cancer, etc. These diseases hinder the circulation of bilirubin, causing the skin to become very yellow. Jaundice is most obvious in the feet, hands, eyes or face.

It is best to see a doctor to check the condition of the liver and gallbladder with tests such as: Liver enzymes, liver function, bile, hepatitis virus status, liver, bile, pancreas ultrasound.

3. Pale white toenails: Kidney damage

When our kidneys are damaged, it will certainly disrupt the body's blood circulation. When anemic, the body has a reflex to send blood to nourish more essential organs, so the feet - which are the lowest organs - will not receive enough blood, the clearest sign is that the toenails or skin of your feet turn white and pale.

In addition, if your fingernails and toenails grow crookedly and are thinner than normal, you need to see a doctor immediately because it could be a sign of kidney damage.When your internal organs are healthy, what will your feet look like?
