Liver disease doesn't always cause noticeable signs and symptoms. However, you might experience slight changes in yourself. If the signs and symptoms of liver disease do occur, you should visit the doctor. According to Dr. Deepak, the symptoms of liver diseases are:

  • Progressive jaundice
  • Severe loss of appetite
  • Swelling in the face or stomach

Causes of liver diseases

Parasites and viruses can infect the liver, disturbing the functions of liver. This can even spread in the whole body through the bloodstream of a person. As per Dr. Deepak, here are the major causes of liver diseases:

1. Hepatitis C and B

Hepatitis C occurs by an infection that is caused by a virus. This can damage the liver, resulting in severe inflammation. On the other hand, hepatitis B is a very severe liver infection which can be treated through vaccines.

2. Jaundice


Jaundice can also make the liver inflammed and makes your skin and eyes go yellow in colour. Jaundice is a cause of waste material buildup in the blood, further causing severe liver damage.

3. Certain medicines

Drug induced jaundice can also occur in some people. The medications given for tuberculosis (TB) very often causes jaundice, resulting in severe liver diseases. Therefore, certain medicines can also be a reason behind liver diseases. 

4. COVID-19 and other infections

Even COVID-19 can also cause liver dysfunction very frequently. Coronavirus can also affect your liver adversely. Various infections can also cause jaundice, further resulting in liver diseases.

5. Genetic factor

There are certain diseases which are very uncommon and are genetically inherited, for example, Gilbert's syndrome. These diseases can also cause jaundice. Therefore, genetic factor can also be a factor behind liver diseases. 

6. Cancer

Other reason for jaundice could be cancer which may obstruct the flow of our bile. So, an ultrasound is very helpful in differentiating between an obstruction and hepatitis or infection. So, liver cancer is also another cause for the damage.

7. Gall bladder stones

Gall bladder stones can even cause jaundice by obstructing the flow of bile. So, gallstones are also a major reason behind liver diseases. The gallstones can cause bile duct infection and severe pain too.

Liver problems diagnosis and treatment


Dr. Deepak said, "Once you suspect that you have a liver problem, the person has to go for a full physical examination and blood test. There is also a liver function test to check the stage of the liver disease. Hepatitis markers like hepatitis B, C,A and D are also used for diagnosis. An ultrasound might also be very helpful in such health conditions." The treatment for liver diseases totally depends on the cause and etiology of jaundice. He further added and said, "If it is a fatty liver disease which is basically a lifestyle disease, then the treatment would be very very strict. Control of blood sugar, weight loss and other liver medications can be given in such situations. None of the medications have been approved by the government worldwide."
