What are the effects on the body of having one less liver?

　　The human body originally has two livers. Missing one liver can have serious effects on the body, such as reduced immunity, decreased metabolic capacity, and respiratory discomfort, among others, as detailed below:

　　1. Reduced Immunity

　　Liver function maintained at around 40% is sufficient to support normal physiological functions. However, if liver function declines, the body's resistance to diseases and pathogenic attacks will decrease.

　　2. Decreased Metabolic Capacity

　　The liver plays a crucial role in metabolism and waste elimination. If the body has only one liver, even if it functions normally, it can only perform work that would normally require two livers, thereby slowing down the body’s metabolic rate.

　　3. Respiratory Discomfort

　　The liver is an important component of the immune system. Liver deficiency can impair immune function, making the body more susceptible to infections. Individuals with a missing liver may experience abnormal breathing, as the remaining liver may not produce enough collagen to maintain the diaphragm connected to it.

　　Additionally, there may be an increased risk of cardiovascular disease. However, if the remaining liver functions well and can operate at double capacity, or if comprehensive medical management is provided by healthcare professionals, it may be possible to restore a healthy lifestyle and reduce the risk of potential complications.
