Why Liver Health Matters
Hi friends! In today’s episode, we are talking about our livers and why it’s so important that we take good care of them! The health of our livers is probably not something that often crosses our minds, but it is one of the most important organs in our bodies both for everyday function and long-term health. So let’s get into talking about the liver…

The liver is the unsung hero of our bodies. It performs over 500 essential functions and unless something is going wrong, it rarely ever gets noticed. Most people I know don’t go around thinking about their livers throughout the day, yet it’s functions are vital to all other body systems’ ability to function.
For example, here are a few of the essential functions the liver is responsible for:
Digestion and absorption
Our livers help turn our food into energy. It stores and distributes both fat and glucose, as well as metabolizes both cholesterol and protein. It produces bile which is vital for digestion and absorption of key vitamins and nutrients and then distributes those nutrients out to the body. It also produces key enzymes that are needed for other chemical reactions all over the body. In addition to distribution, it also stores vitamins and minerals that will be needed in the future. So just by listing these few things, this shows that our livers help regulate our blood sugar, cholesterol, and hormone levels.
Immune Function
Our livers produce of certain proteins and components of the immune system such as cytokines as well as various other immune cells. Our livers maintain a certain amount of controlled inflammation which assists the body in detoxification, but when this becomes uncontrolled or dysregulated, it can lead to systemic inflammation which damages the immune system and can even lead to auto-immunity or cancer.
Hormone Function
The liver is hugely important for hormone health. Our livers create proteins and cholesterol that carry hormones all over the body. In addition, it also helps deactivate hormones and assist with ridding our bodies of excess hormones, or ones that we no longer need. This process is vitally important. For example, with the hormone estrogen, our livers actually regulate which kind of estrogens our bodies produce, as well as help with the processes that remove excess estrogen from the body. Without this essential function, an excess of estrogens can build in the body leading to estrogen-dominant diseases and cancer.
Detox
The function that our livers are best know for is detoxification. The liver is responsible for the movement of the blood in our bodies. As a matter of fact, almost 1½ liters of blood pass through our liver every single minute in order to be filtered. Through this process it extracts toxins and stores nutrients for later use (which we discussed when talking about digestion and absorption). The liver detoxifies in three phases that must stay in sync with each other.
Phase One is bioidentification. This is when your body sends out enzymes that put a red flag on all toxins. Phase two is conjugation. This is when the body attaches molecules to those flagged toxins to make them either water soluble or fat soluble. Phase three is elimination. This is when the body actually flushes the toxins from our bodies when we use the bathroom (and sometimes through sweat). If one of these phases isn’t working correctly, it can damage our body’s cells and allow the toxins to continue to circulate in our bodies, further taxing our livers and creating a loop of inflammation. Every single substance we breathe, ingest, or absorb through our skin will pass through our liver, which creates a huge workload for it every single day.
The point here is that every other system in the body is dependent on the function of the liver and when our livers are healthy, and functioning well, this works great! However, the truth is that the majority of Americans are walking around with less-than-healthy livers.
What happens when our livers aren’t healthy
It’s estimated that up to 90 million Americans (that’s almost ⅓ of the American population) has Fatty Liver Disease, which is basically inflammation of the liver that occurs when apprx. 5% of cells in the liver are replaced with fat cells. This causes the liver to be unable to keep up with it’s 500+ essential functions and add to systemic inflammation in the rest of the body, which can lead to other chronic diseases like heart disease, diabetes, even Alzheimers and Dementia.
If Fatty Liver Disease is left untreated, it can progress into Fibrosis, and even Cirrhosis of the liver, which leads to liver failure (fatal). Liver Disease doesn’t just occur because of alcohol or drug use or Hepatitis. Non-alcoholic fatty liver disease is the most common form of liver disease and is caused by a combination of lifestyle and genetics - most commonly high-starch/high-sugar diets, insufficient protein intake, intake of trans fats and artificial chemicals, unresolved emotions and trauma, lack of movement in the lymphatic system, and overexposure to environmental toxins. It’s not usually only too much fat, as the name would suggest.
Symptoms of an unhealthy liver or fatty liver disease
There aren’t always immediate symptoms, which can make it tricky. When symptoms do occur, some common ones are:
Abdominal pain, fullness in the upper right side
Nausea, loss of appetite (especially in the AM)
Swelling in legs/abdomen
Fatigue
Brain Fog/confusion
Waking up at night in the 2-3 am range regularly
You can ask your provider to run labs to check enzyme levels most commonly found in the liver ALT and AST. If either level is over 30, especially ALT, this can be indicative of a damaged liver. It’s important to note that by the time these levels are above normal, damage to the liver is already happening. So we don’t want to wait until then to care for and support the health of our liver.
The good news is that livers regenerate and that our body has an amazing ability to heal. It will need some support from us, but an unhealthy liver, even most diseased livers, with the exception of cirrhosis, can be become healthy and well-functioning again.
In the next episode, I am going to share ways that you can support your liver health to prevent an unhealthy, sluggish, or diseased liver, as well as ways that you can help your liver to heal if you are already experiencing liver dysfunction or disease. Make sure you stay tuned for that episode!
