Why is the thenar and hypothenar on my left hand a little dark?

When suffering from chronic hepatitis, especially cirrhosis of the liver, the skin at the thenar eminence at the base of the thumb and little finger may appear flaky congestion, or red spots or plaques, which turn into red spots after pressure. The palms are pale in color. This kind of palms that are different from normal people are called liver palms. Most of the patients with liver cirrhosis are prone to liver palms.

Causes of liver palms:

Normal men and women each have a slightly triangular gland above the kidneys that secretes human hormones, called the adrenal gland. This gland continuously produces estrogen and maintains a normal level of relative balance with the male hormones produced by the body, thus ensuring that the body Normal physiological and biochemical metabolic functions in this regard. In addition, female ovaries also produce this hormone. Estrogen secreted by human sexual organs must pass through the liver before its function can be weakened or its activity disappears.

But when When acute or chronic inflammation or other diseases occur in the liver, the ability to inactivate estrogen is significantly reduced, resulting in a large accumulation of estrogen in the body, which causes the expansion of arterioles in the body. Spider nevus is the result of the expansion of arterioles on the skin and mucous membranes. Because After the small arteries are expanded, they resemble a spider web. If you press the "spider body" with the tip of a pencil, the web-like shape will disappear immediately. This nevus is as small as a grain of millet, and the largest one is 2 to 3 centimeters, with a small number of 1 to 2, and even a few. Hundreds; mostly seen above the chest, face and neck, and backs of upper limbs and hands. The incidence of spider nevus in patients with acute hepatitis is about 1%, while with chronic hepatitis it can reach about 54%. The appearance of spider nevus is often parallel to the status of liver function. When liver function deteriorates, spider nevus can increase sharply. After liver function improves, the nevus can change from bright red to brown-black and then disappear. The imbalance of estrogen inactivation can also cause hepatitis patients to suffer from telangiectasia, menstrual disorders, and testicles. Atrophy or gynecomastia development. If things go on like this, it can also cause an increase in melanin in skin cells, causing hepatic swarthy appearance.

The presence of liver palms does not necessarily mean liver disease. Clinically, it is often seen that many healthy people also have liver palms. , but after many years of observation, the liver function has always been normal and liver disease has never occurred. Therefore, for those with liver palms, multiple examinations such as medical history, physical examination, liver function, hepatitis B virus surface antigen, B-ultrasound, and scans should be combined Only after comprehensive analysis and judgment can we make the correct conclusion.
