6 things that can harm your liver

6 things that can harm your liver

To protect our liver, we first need to know what harms our liver. We all know that alcohol can harm our liver, but what other dangers are there? 

The liver is involved in many critical functions that keep us healthy. Learn more about the things that can cause damage and help your liver to guard your health.



All medication are processed by the liver and can potentially harm it. During the process, the medication undergoes chemical changes. While the original product might not be harmful, the resulting by-products may be toxic to the liver. Sometimes, the interaction of different medications, or when combined with alcohol, may cause life-threatening complications. [1]

Overdose or long term medication may cause hepatotoxicity, which means chemical-driven liver damage. If taken in the long term, some drugs or chemicals can induce chronic hepatitis or even cirrhosis. [2] So it is important to read the information leaflet before use. Learn how the medicines you take might affect your liver and take the medications as directed. [3]



Heavy alcohol consumption is one of the most common causes of liver damage. When you drink alcohol, the liver works overtime to convert ethanol into a less toxic form which we eventually release as urine. This means that the liver gets diverted from its other primary functions and focuses mainly on converting alcohol.

Excess alcohol intake can also cause fat to build up in your liver. The fat deposited due to absorption of alcohol can cause fatty liver disease. It also causes inflammation of the liver which leads to alcoholic hepatitis and may progress to cirrhosis after many years of heavy drinking. [4]



The liver normally helps to process and regulate the amount of sugar and fat in the blood. But when the liver becomes overwhelmed, it starts storing excess fat in its own liver cells, causing non-alcoholic fatty liver disease (NAFLD).

If too much fat builds up, or if certain genetic conditions are present, the fatty liver tissue can become inflamed and the liver cells can be damaged or destroyed. This is called non-alcoholic steatohepatitis (NASH). If the inflammation persists, it may lead to cirrhosis of the liver and liver failure. [5] 


Hepatitis virus

Hepatitis is an inflammation of the liver and can have many different causes. Viral hepatitis is the most common cause of hepatitis worldwide. 

There are 5 main hepatitis viruses, types A through E. Hepatitis B (HBV) and hepatitis C (HCV) are the most common viral hepatitis. The virus attack the liver cells, causing inflammation. If the liver inflammation last less than six months, it is considered acute hepatitis; if the disease course becomes longer than six months, the liver inflammation is chronic. Chronic viral hepatitis may advance to cirrhosis and liver failure. [6]



Fibrosis is the accumulation of scar tissue in the liver. Over time this process can result in cirrhosis of the liver.

Chronic infection with HCV or HBV, heavy alcohol consumption, toxins, or trauma can all lead to liver fibrosis, but sometimes the cause is unknown. When liver cells are injured due to a virus, alcohol, toxins, trauma or other factors, the immune system tries to repair the damage. During the process, scar tissue builds up and may eventually affect liver function. [7] 



There are two types of liver cancer. Primary liver cancer is cancer that starts in liver cells. Apart from this, the liver can also be affected by cancer which was formed in another part of the body and spread to the liver. This type of cancer is called secondary or metastatic liver cancer. Almost any cancer can spread to the liver, but the most common ones include bowel, lung and breast cancer. Since all the blood in the body passes through the liver, it becomes a likely place for the cancer cells that have escaped into the bloodstream to settle. [8]

In a recent study published in Scientific Reports, experts have warned that the common over-the-counter painkiller could be as bad for your liver as cancer.   Paracetamol or acetaminophen (you may recognize it as Tylenol) overdose can damage liver tissue structure. Dr Leonard Nelson from the University of Edinburgh, who co-led the study, said: "Paracetamol is the world's preferred pain remedy - it is cheap, and considered safe and effective at therapeuti
Nonalcoholic fatty liver disease (NAFLD) is a condition in which fat builds up in your liver. NAFLD is one of the most common causes of liver disease in the United States. Between 30 and 40 percent of adults in the United States have NAFLD. About 3 to 12 percent of adults in the United States have NASH (a form of NAFLD in which you have inflammation and liver cell damage). [1] Recent research found that NAFLD not only increases the risk of chronic liver diseases such as NASH, l

Fibrosis is scarring of the liver that results from chronic inflammation. It is a process where the damaged, dying liver cells are replaced by fibrous scar tissue, causing the liver to become hard. The extent of liver fibrosis can vary, and it is often classified in several stages. The most common classification is a scale from F0 to F4. F0 indicates no fibrosis. A normal liver is at a stage between F0 and F1. F2 denotes light fibrosis, and F3 indicates severe fibrosis. When scar tissue build
You probably have already heard about the new antiviral hep C drug, which is effective but insanely expensive. It claims to have around 90% success rate, that’s why so many hepatitis C patients are dying for it even though it’s extremely costly. But apart from its expensive price tag, there is a bigger issue behind this new drug that not many people know about. Scientists and researchers have found an increased risk of extreme liver cancer related to this new drug after successful
ALT (Alanine Aminotransferase / SGPT) is an enzyme that is mainly found in liver cells. The level of ALT in our bloodstream is the primary indicator of liver health.   What does high ALT indicate? ALT enzymes are normally contained within liver cells when the liver is healthy, but when the liver cells are injured or damaged by whatever means, ALT enzymes are released into the bloodstream, causing levels to go up. Therefore, by measuring the
Hepatitis C is a wide spread and deadly disease affecting an estimated of 3.5 million Americans.   Treatment for hepatitis C has evolved over the years, going from highly toxic drugs involving injections with horrible side effects, to medications with minimal side effects. Success rate of treatment options has also improved greatly Although the high price tag of the new DAA treatment is controversial, it has undoubtedly helped to cure many hepatitis C patients.
