Our liver - the most efficient detoxification organ

The importance of the liver as one of the most essential organs in the human body is often overlooked when discussing important body parts. Nevertheless, the smooth functioning of the organism is unthinkable without the liver, as it takes on a variety of essential metabolic functions. Their role is not limited to detoxification alone; it also plays a crucial role in converting and storing nutrients from the food consumed to make them usable for the body. A notable feature of the liver is its ability to regenerate, making it the only organ in the body that can regenerate itself.

But how exactly does this central chemistry laboratory work in our organism? And why do liver diseases often lead to serious consequences? The liver, which is one of the largest organs in our body and weighs around one and a half kilograms, remains largely inconspicuous. It is located below the ribs, in the upper right corner of the abdomen, directly under the diaphragm. It moves with every breath, lowering as you breathe in and rising as you breathe out. In its role as a central metabolic center, the liver can store, break down, convert and even produce various substances.

Anatomy of the liver: division into lobes and lobules

The liver is made up of the right and left large lobes and two smaller lobes. However, the exact fine structure of the liver tissue is of crucial importance. This organ consists of an estimated number of over a million tiny liver lobules, which are considered the smallest functional unit. These lobules are made up of liver cells and are only about one to two millimeters in size and have a hexagonal shape. When you look at tissue samples, they resemble the appearance of honeycombs.

Since both nutrients and pollutants enter and leave the liver via the blood, blood vessels run through the liver tissue. Among these blood vessels, the most important is the so-called portal vein, which acts as a vein. Another major bloodstream is the hepatic artery, which carries oxygen-rich blood from the heart to the liver. Each liver lobe has a central vein. In the smallest blood vessels in the liver tissue, the capillaries, the oxygen-poor but nutrient-rich blood from the veins mixes with the oxygen-rich blood from the arteries.

Functions of the liver:

  1. Digestion and metabolism: The liver produces bile, which enters the small intestine and helps digest fat. It is also involved in converting nutrients such as carbohydrates, fats and proteins into energy.
  2. Detoxification: The liver filters harmful substances from the blood, including breakdown products from medications, alcohol, pollutants and metabolic waste. It converts these substances into less toxic forms, which are then excreted in the bile or urine.
  3. Storage of nutrients: The liver stores important nutrients such as vitamins (especially vitamins A, D, E and K), minerals and glucose. When needed, it releases these nutrients into the blood to fuel the body.
  4. Production of proteins: The liver is responsible for the production of many vital proteins, including blood clotting factors, albumin (which is important for maintaining blood volume), and enzymes that play a role in various metabolic processes.

Tips for caring for your liver:

  1. Healthy diet: A balanced diet rich in fruits, vegetables, whole grains, lean proteins and healthy fats supports liver health. Limit consumption of saturated fats, sugary foods and overly processed products.
  2. Moderate alcohol consumption: Excessive alcohol consumption can damage the liver. It is advisable to consume alcohol in moderation and to take breaks from alcohol to reduce the strain on the liver.
  3. Weight control: Overweight and obesity increase the risk of liver disease. By maintaining a healthy weight, you can protect your liver.
  4. Physical Activity: Regular physical activity not only helps control weight but also supports metabolism and overall liver health.
  5. Be careful with medications: Some medications can put strain on the liver. Use prescription and nonprescription medications only as recommended and consult a doctor if you have any concerns.

Liver diseases and prevention:

  1. Fatty liver disease (NAFLD/NASH): Non-alcoholic fatty liver disease (NAFLD) is characterized by the accumulation of fat in the liver. As NAFLD progresses, non-alcoholic steatohepatitis (NASH) can develop, which can lead to inflammation and liver damage. Risk factors for NAFLD/NASH include obesity, diabetes, insulin resistance and an unhealthy diet. Prevention includes maintaining a healthy weight, regular exercise, and a diet low in saturated fats and sugary foods.
  2. Hepatitis: Hepatitis refers to the inflammation of the liver. The most common forms are hepatitis A, B and C, which are caused by viruses. Hepatitis can lead to liver damage, cirrhosis and liver cancer. Vaccinations are available to protect against hepatitis A and B. Hepatitis C can often be treated and cured. Safe handling of needles, safe sexual behavior and hygienic habits contribute to prevention.
  3. Liver cirrhosis: Long-term damage to the liver, often from chronic alcohol consumption or chronic hepatitis, can lead to cirrhosis. This involves replacing healthy liver tissue with scar tissue, which impairs liver function. Early diagnosis and treatment of underlying causes are critical to slowing the progression of cirrhosis.
  4. Liver cancer (hepatocellular carcinoma): Some liver diseases, particularly cirrhosis and chronic hepatitis, increase the risk of liver cancer. Regular check-ups, especially for people at increased risk, enable early detection and treatment.

Additional Liver Health Tips:

  1. Hydration: Adequate fluid intake is important to support liver function. Water helps flush toxins from the body.
  2. Avoid excessive medication use: Excessive use of over-the-counter or prescription medications can put strain on the liver. Always consult a doctor or pharmacist before taking any new medications.
  3. Stress management: Chronic stress can affect liver health. Relaxation techniques such as yoga, meditation and regular physical activity can help reduce stress.
  4. Avoiding Toxic Exposures: Limit exposure to toxic chemicals, pesticides, and pollutants to reduce stress on the liver.

The liver plays an indispensable role in our body and is crucial for the well-being of the entire body. Through a combination of a healthy diet, regular exercise, avoiding risk factors, and regular medical exams, you can help keep your liver in the best possible condition and minimize the risk of liver disease.
