Cirrhosis and sleep disturbances – How much do we know about them?
A:

Cirrhosis patients often experience disturbances in their sleeping patterns, which largely affect their quality of life. While western medical theory often treats health issues by looking at organs individually, Chinese medical theory has a different perspective when it comes to viewing the human body.

View from Chinese medical theory

To tackle the problem of disturbed sleeping patterns in cirrhosis patients, we can first take a look at how Chinese medical theory views the liver and the brain. Often named as the “Sea of Marrow”, the brain does not only control memory but also the circulation of Qi, a type of energy that can be interpreted as “life force” which maintains the healthy state of our bodies. And the linkage between the brain and the liver is that the liver also takes care of the flow of Qi and emotions. When a person is stressed, not only does the brain suffer but also the liver. In TCM, psychological illnesses such as depression have long been treated by managing the liver Qi circulation through the use of herbs that promote such circulation in the liver. 

Causes of sleep disturbances in cirrhosis patients

According to a research conducted by Indiana University School of Medicine, 81% of cirrhosis patients suffer from sleeping disturbances. Their most common complaints are insomnia, hypersomnia, and unusual events associated with sleep, for example apnea and heavy snoring. 

Even though sleeping problems are common among cirrhosis patients, little research have been done to investigate the possible causes of this phenomenon. Based on a study conducted by National Center for Biotechnology Information, impaired hepatic melatonin metabolism is observed among cirrhosis patients. In a healthy individual, melatonin, a hormone that is released at night to induce sleep, will increase in level at around 9pm and stay in blood for the next 12 hours. However, in cirrhosis patients, their melatonin levels are higher during the day and the onset of melatonin peaking is often delayed at night. 

Another possible cause is cirrhosis patients’ sleep-wake and circadian abnormalities. Circadian rhythm refers to mental, physical, and behavioural changes driven by a circadian clock that repeats around every 24 hours. It is noticed that cirrhosis patients have a preference for activities at night when compared with other healthy individuals. The tendency of preferring doing activities at night could alter the natural circadian cycle. Below shows a figure presenting other possible mechanisms that might affect circadian regulations in cirrhosis patients.


 

 

 

 

 

 

 

 

 

 

 

Ways to manage sleep disturbances

Common ways to improve cirrhosis patients’ sleep disturbances is light therapy. Patients will be exposed to artificial light that mimics natural outdoor light so as to bring back the natural circadian cycle. The advantage of this treatment is the lack of toxicity since most patients are already taking quite a number of pills for their cirrhosis treatments. Patients can also practice regular sleeping schedule and avoid over exposure to light in the evening.

While treatments like this do help, from Chinese medical theory’s point of view, it is crucial to bear in mind that the health of the brain and the liver are interconnected. Since sleep disturbance is caused by a malfunctioning liver, it is always a good measure to improve the liver function first. Based on a research that studies the effectiveness of herbal liver therapy, patients of liver diseases who were provided with the said herbal supplement showed a significant decrease in their transaminases level, suggesting a drop in their liver damage degree. User reviews also show that patients have more energy in their daily lives afterwards. All these suggest that once the liver function is improved, so will the quality of sleep.

Cirrhosis has always been a tricky liver condition to tackle, given its complications and symptoms that are difficult to manage. A recent study published in the American Journal of Physiology-Gastrointestinal and Liver Physiology mentions that lowering the inflammation level of cirrhosis patients’ oral cavity helps improve the overall inflammation level in the body, which could help minimize some of the symptoms cirrhosis patients experience. This study highlights the i

Cirrhosis patients often experience different problems derived from a malfunctioning liver, and malnutrition is one of the most common issues. As the liver has a key role in regulating the overall nutritional state and the energy balance, a liver that is not functioning properly will affect the body in various ways. According to data from National Center for Biotechnology Information, on average, cirrhosis patients lose 7.7 ± 12.4 kg due to malnutrition and it gets worse with

The liver carries out essential functions, including detoxifying harmful substances in your body, cleaning your blood and making new blood and other vital nutrients. Cirrhosis is scarring of the liver caused by long-term liver damage. The loss of liver cells turns into scar tissue which prevents the liver working normally, reducing or in some cases, completely losing liver function. Cirrhosis is a long-term chronic liver damage; it is often caused by chronic live

ALT (Alanine Aminotransferase / SGPT) is a type of enzyme found in liver cells. When the liver cells are functioning normally, the ALT enzymes should be contained within the liver cells.    You can imagine each liver cells as a balloon, and the ALT enzymes are the air inside the balloon. When the balloon is damaged, the air will be released. And when the liver cells is damaged, ALT enzymes are released into the bloodstream, therefore we are able to find out the l

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

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
