What is the Liver?
The liver is an organ found in vertebrates. It detoxifies various metabolites, synthesizes proteins, and produces biochemicals necessary for digestion and growth. It is located in the right upper quadrant of the abdomen, below the diaphragm in the human body. Its other roles in metabolism include the regulation of glycogen storage, decomposition of red blood cells, and the production of hormones. The liver is an accessory digestive organ that produces bile, an alkaline fluid containing cholesterol and bile acids, which helps the breakdown of fat. The gallbladder stores bile produced by the liver which is afterward moved to the small intestine to complete digestion.

Medical Structure of the Liver
Liver Disease
Liver disease is any disruption of liver function that induces illness. The liver is accountable for numerous crucial tasks within the body and if it becomes diseased or injured, the loss of those functions can result in crucial damage to the body. It is a wide term that encircles all the potential problems that cause the liver to fail to conduct its designated tasks.
Symptoms of Liver Problems
Classic symptoms of the liver problem include nausea, vomiting, right upper quadrant abdominal pain, jaundice, fatigue, weakness, and weight loss.
Gallstones - A person with gallstones may undergo right upper abdominal pain and vomiting after consuming a greasy meal. If the gallbladder becomes infected, fever may occur.
Gilbert's Disease - It has no symptoms and is an incidental finding on a blood test where the bilirubin level is mildly increased.
Cirrhosis of the Liver - It develops advanced symptoms as the liver fails. Some symptoms are directly associated with the inability of the liver to metabolize the body's waste products.
Common Liver Problems
Hepatitis- It is a viral infection that causes inflammation of the liver and damages it. Hepatitis is of five different types – Hepatitis A, B, C, D, and E.
Fatty Liver Disease: It refers to the addition of fat in the liver. It can be of two types – an alcoholic fatty liver disease caused by consumption of alcohol and non-alcoholic fatty liver disease caused by other factors.
Autoimmune Conditions: In this, the immune system accidentally attacks the healthy cells in our body.
Causes of Liver Problems
Cancers - Primary cancers in the liver emerge from liver structures and cells. Two examples include hepatocellular carcinoma and cholangiocarcinoma.
Congestive Heart Failure - Poor heart function results in fluid and blood to back up in the huge veins of the body can result in liver swelling and inflammation.
Abnormalities of the opening of the bile duct into the small intestine can lead to abnormalities of bile flow. The sphincter of Oddi functions as a "valve" that permits bile to flow from the common bile duct into the intestine.
Abnormal Bleeding - The liver is accountable for generating blood clotting factors. Decreased liver function can cause an increased risk of bleeding in the body.
Protein Synthesis or Manufacture - proteins made in the liver are the building blocks for body function. Lack of protein affects many bodily functions.
Prevention of Liver Problems
Drink Alcohol in Moderation - Heavy or high-risk drinking is defined as more than eight drinks a week for women and more than 15 drinks a week for men.
Use Medications Properly - Take prescription and nonprescription drugs only when required and in recommended doses. Don't mix medications and alcohol. Speak to your doctor before mixing herbal supplements or prescription or nonprescription pills.
Keep Your Food Safe - Wash your hands completely before eating or making foods.
Nurture Your Skin - When using insecticides and other toxic chemicals, wear gloves, long sleeves, a hat, and a mask so that chemicals aren't consumed through our skin.
Maintain a Healthy Weight - Obesity can result in nonalcoholic fatty liver disease.
Did You Know?
According to the American Liver Foundation, at least 10 percent of Americans have some form of liver disease. Further, the American Liver Foundation reports that hepatitis C, non-alcoholic fatty liver illness, and liver cancer exist with greater incidence.
Alcohol abuse, hepatitis viruses, and obesity are all deemed highly preventable and are the major three risk factors for death from liver disease. Other causes of liver disease include cancer, autoimmune diseases, and genetic or metabolic disorders.
Sadly, symptoms of many liver disorders do not manifest until serious – sometimes irreversible – the damage has occurred. A population-based study found that 69 percent of adults with cirrhosis were unaware of having liver disease. Another study found that Hispanic Americans and African Americans are at greater risk of developing liver disease than Caucasians.
Hispanic Americans have greater risk due to heavier drinking and higher prevalence of obesity and diabetes, while African-Americans have a higher prevalence of obesity, diabetes, and hepatitis B or C.
FAQs on Symptoms of Liver Problems
1. What are some of the most common early symptoms of a liver problem?
Early liver problems can be subtle and may not always be obvious. Key signs to watch for include:
- Persistent fatigue and a general feeling of weakness.
- Unexplained weight loss or loss of appetite.
- Nausea and occasional vomiting.
- Pain or discomfort in the upper right abdomen, where the liver is located.
- A yellowish tint to the skin and eyes, a condition known as jaundice.
2. What is jaundice, and why is it considered a major sign of liver dysfunction?
Jaundice is the yellowing of the skin and the whites of the eyes. It is a critical indicator of liver problems because it signifies the liver's inability to properly process bilirubin. Bilirubin is a yellow pigment formed from the breakdown of red blood cells. A healthy liver filters bilirubin from the blood and excretes it. When the liver is damaged, bilirubin builds up in the bloodstream, causing the characteristic yellow discoloration.
3. Can liver issues cause digestive problems like bloating, gas, and indigestion?
Yes, liver problems can directly impact digestion. The liver produces bile, which is essential for digesting fats in the small intestine. When liver function is impaired, bile production may decrease or be blocked. This can lead to symptoms like bloating, excessive gas, indigestion, and pale, greasy stools, as the body struggles to break down fatty foods.
4. How do lifestyle factors like alcohol and diet contribute to liver damage?
Lifestyle plays a crucial role in liver health. Excessive alcohol consumption is a primary cause of liver disease because the liver is the main organ responsible for metabolizing alcohol. This process can produce harmful byproducts, leading to inflammation (alcoholic hepatitis) and eventually irreversible scarring (cirrhosis). Similarly, a diet high in processed fats and sugars can lead to fat accumulation in the liver, causing Non-Alcoholic Fatty Liver Disease (NAFLD), which can also progress to more severe liver conditions.
5. What is the difference between hepatitis and cirrhosis?
Hepatitis and cirrhosis are related but distinct liver conditions. Hepatitis refers to the inflammation of the liver, which can be caused by viruses (like Hepatitis A, B, C), alcohol, toxins, or autoimmune diseases. It can be acute (short-term) or chronic (long-term). Cirrhosis, on the other hand, is a late-stage condition characterized by irreversible scarring (fibrosis) of the liver tissue. Chronic hepatitis is a common cause of cirrhosis, as the persistent inflammation gradually destroys healthy liver cells and replaces them with scar tissue, severely impairing liver function.
6. What are the signs of advanced liver disease or liver failure?
As liver disease progresses to advanced stages like severe cirrhosis or liver failure, symptoms become much more serious. These can include:
- Fluid buildup in the abdomen (ascites).
- Swelling in the legs and ankles (edema).
- Mental confusion, drowsiness, or slurred speech (hepatic encephalopathy) due to toxin buildup in the brain.
- Easy bruising and bleeding, as the liver can no longer produce sufficient clotting proteins.
- Vomiting blood or having black, tarry stools due to bleeding in the upper digestive tract.
7. Are liver problems and the damage they cause treatable?
The treatability of liver problems depends on the cause and the stage of the disease. In the early stages, such as fatty liver disease or mild inflammation, damage is often reversible through lifestyle changes like adopting a healthy diet, losing weight, and stopping alcohol consumption. However, advanced conditions like cirrhosis involve permanent scarring that is generally not reversible. In these cases, treatment focuses on managing symptoms, preventing further damage, and, in severe cases of liver failure, a liver transplant may be the only option.
8. When should a person consult a doctor about potential liver symptoms?
It is crucial to consult a doctor if you experience any persistent or concerning symptoms. You should seek immediate medical evaluation if you notice jaundice (yellow skin or eyes), as this is never normal. Other critical signs that require a doctor's visit include severe abdominal pain, persistent vomiting, dark-coloured urine, pale stools, and unexplained fatigue or weight loss. Early diagnosis and intervention are key to managing liver disease effectively.
