Energy is the driving force behind all human activities, and when it becomes disordered, it can lead to various organ disorders. In turn, organ disorders can also cause energy disorders. Energy disorders are generally categorized as either deficiency or excess. Deficiency refers to a shortage of energy, with symptoms of decreased functioning and decline, while excess refers to an overabundance of energy, with symptoms of congestion and blockage.

In cases of energy deficiency, there is a decline in the functioning of internal organs and a weakened resistance to disease. This can be observed in chronic diseases, aging, or during the recuperation stage of acute diseases. General symptoms of energy deficiency include a pale complexion, fatigue, weakness, low spirits, shortness of breath, fatigue when speaking, a weak voice, excessive perspiration, a tongue with a light color, and a weak pulse. In order to treat energy deficiency, it is necessary to tonify or strengthen the energy.

Excess energy is characterized by sluggish or stagnant energy circulation. Energy should travel smoothly throughout the body, but various factors such as emotional stress, irregular eating habits, exposure to external energies, and external injuries can negatively impact energy circulation and cause sluggishness in the chest. This can lead to stomach and abdominal swelling and pain if the stomach and intestines are involved. Wandering pain is the most common symptom, and swelling is usually more severe than pain. Other symptoms may include intestinal rumbling, pain that improves upon belching, and breast pain and swelling in women. To treat excess energy, it is necessary to promote energy circulation and break up energy congestion.

Energy upsurging or energy rebellion is another type of energy disorder, which can result in coughing and asthma due to an upsurge of lung energy, or nausea and vomiting due to an upsurge of stomach energy.
