Liver: Its Functions And Conditions Affecting It


If you were to name an important solid organ in your digestive system, it would be the liver. It is mainly a football-sized organ that is situated on the right side of the abdomen. Its primary function is to digest the food you eat and eliminate the toxins from the body. 

Certain diseases and lifestyle changes can affect this organ. If these conditions are left untreated, they can become life-threatening. But before we move to the conditions affecting the liver, let us look some of its major functions. 

What are the functions of the liver?

Production of albumin

Albumin is a protein produced by the liver. It keeps the fluid in the blood from leaking into other tissues. It is also responsible for carrying vitamins, hormones and enzymes throughout the body. 

Production of bile

Bile is a digestive fluid that is stored in the gall bladder. The primary function of the bile is to break down fat into fatty acids so that it can be carried to different parts of the body through the digestive tract. 

Clears the blood

The blood from the stomach and intestine passes through the liver. which then removes all the toxins and harmful substances from the blood and filter them. Besides toxins, bacteria present in the blood is also being removed. 

Stores excess glucose

Excess sugar or glucose in the blood is removed by the liver and is stored as glycogen. This glycogen can later be converted back to glucose as needed. 

What are the conditions affecting the liver?

The proper functioning can be affected by various factors. Some examples include: viral attack, alcohol use, obesity and genetic factors. 

Here are some of the conditions:

Hepatitis A

Hepatitis A is a liver infection caused by the Hepatitis A virus. It causes inflammation in the organ and can affect its normal functioning. 

Hepatitis A is found in the stool or blood of an infected individual and is highly contagious. You can get infected when ingesting even very small amounts that is in contaminated food or drinks. In addition, coming into close contact with a person infected with Hepatitis A also increases your risk of contracting this condition. 

Hepatitis B

Hepatitis B is a liver infection caused by the Hepatitis B virus. Severe cases of hepatitis B can result in liver failure or cancer. 

Hepatitis B spread from one person to another either through semen, blood or other body fluids. Sharing personal items of an infected person like nail clippers, toothbrush, or razor can also lead to the spread of the disease. 

Hepatitis C

Hepatitis C is a condition caused by the hepatitis C virus. It can cause inflammation of the organ and is a major cause of liver cancer. 

Like hepatitis B, hepatitis C also spreads through direct contact with an infected person. For example, sharing personal items like toothbrush and nail clippers, tattooing with unclean equipment, and having unprotected sex with an infected person all can cause hepatitis C. 

Fatty liver

Fatty liver is a condition in which your body produces excess fat, which is not used correctly. When this happens, fat is stored in the liver. Too much fat can cause inflammation and scarring and can even result in failure of the organ. 

There are various causes of fatty liver. In people who are alcoholic, consuming a lot of alcohol can result in it. Obesity and high blood sugar can also make the condition worse. 


Cirrhosis is an advanced stage of disease in which the organ is permanently scarred. One of the leading causes of liver cirrhosis is alcohol abuse. Having other liver conditions like viral hepatitis and lifestyle diseases like diabetes can worsen the condition. 

What are the symptoms of liver diseases?

The symptoms are not always obvious. It may appear as mild symptoms, and on detailed examination, turn out to be a condition affecting the organ. 

Few of the symptoms include:

  • Fatigue
  • Abdominal pain (fatty liver, hepatitis A and hepatitis B)
  • Weight loss (fatty liver, cirrhosis)
  • Nausea (hepatitis A and C)
  • Loss of appetite (hepatitis A and C)
  • Yellowing of the eyes (hepatitis B and C)
  • Dark urine (hepatitis B)
  • Low-grade fever (hepatitis A)
