Spleen deficiency is not indigestion, but it may lead to indigestion along with other symptoms. The causes of spleen deficiency may include irregular diet, overwork, age, excessive thinking or depletion of vital energy after a long illness. Spleen deficiency can be categorized into spleen qi deficiency, spleen qi deficiency, spleen yang deficiency and spleen not regulating blood. For different types of deficiency, the symptoms are different, and the main symptoms of spleen deficiency are loss of appetite, loose stools, prolapsed internal organs and digestive discomforts, which can also cause indigestion. It is important to note that if the spleen is deficient for a long time, it may affect other internal organs, thus triggering symptoms related to other organs. If you have a spleen deficiency, it is recommended that you consult a Chinese medicine practitioner in a timely manner to identify and treat the condition, and do not use your own medication to avoid adverse consequences for your body.
