Liver Health

The liver is the second largest organ in our body after skin. It is the largest solid organ and the largest gland in our body. The liver is situated on the right side of the upper abdomen below the lungs. The liver is an important organ in our body. It works as an engine of the digestive system by controlling metabolic processes efficiently.

Do you know that the liver is the only organ in the body that has the capacity to regenerate? It can regenerate entirely without any functional loss, as long as a minimum of 25% of the healthy liver tissue is left.

Functions of the liver

The liver is a metabolically very active organ. It performs many crucial works to maintain our circulation system effortlessly. The liver synthesizes many essential proteins, filters blood, maintains blood sugar, and stores many vitamins and minerals. Whatever we eat or drink, it is cleansed by the liver.  It performs hundreds of tasks to maintain our body’s functionality. Some of the functions of the liver are:

  • The liver produces and excretes bile. Bile helps in the breakdown and absorbs fats, cholesterol, and some vitamins present in food in the small intestine.
  • The liver synthesizes plasma proteins such as albumin, and clotting factors.
  • The liver filters all the blood from the stomach and intestine. Thus the liver absorbs all the nutrients from the blood. It also ensures to absorb all the waste, harmful products from the blood.
  • The bile of the liver helps in absorbing vitamin K. Vitamin K is needed for blood clotting and bone-building.
  • The liver is a storehouse of many vitamins and minerals like vitamin A, D, E, K, B12, iron, copper, and zinc.
  • The liver absorbs excess glucose of food from the blood and stores it as glycogen in our body. In need, the liver also converts back this stored glycogen into glucose.
  • The liver’s phagocytic cells also known as kupffer cells, plays important role in the immune system by destroying diseases causing pathogens.
  • The liver also filters and metabolizes drugs and alcohol.

Symptoms of poor liver functions

Generally, a liver disease does not show symptoms until it is severe. Symptoms may vary according to disease type but, some symptoms are common if the liver is not functioning properly like:

  • Jaundice is characterized by yellowish skin and eyes
  • Pain and swelling in the right side of the upper abdomen
  • Swelling in ankles and legs
  • Itchiness
  • Dark color urine
  • Nausea and vomiting
  • Sometimes stool color becomes pale color
  • Decreased or loss of appetite
  • Easy bruising
