Excessive phlegm can be caused by either spleen deficiency, spleen dampness or other factors. The specific cause needs to be determined in conjunction with the patient’s other symptoms. Spleen deficiency can cause excessive phlegm, which is usually accompanied by lethargy, yellowish face, weakness of limbs, loss of appetite, indigestion of food, abdominal pain, bowel sounds, loose stools (thin and unformed stools) or diarrhea, swelling, blood in stools, and menorrhagia (excessive or sporadic menstrual flow). Spleen Dampness can cause excessive phlegm, which is usually accompanied by distention and stuffiness in the abdomen (feeling bloated and uncomfortable in the abdomen), greasiness of the mouth and dullness of the stomach (lack of appetite and reduced food intake), generalized nausea and vomiting (nausea and wanting to vomit), lightness of the mouth and lack of thirst, abdominal pain and loose stools, drowsiness in the head and the body (a feeling of heaviness in the head and the limbs), or shortness of urination, swelling of the limbs, yellowish coloring of the eyes and the body, a dull and unglossy coloring of the face, or excessive amount of leucorrhoea in women, and so on. If the symptoms of excessive phlegm are not relieved for a long time or are accompanied by other discomforts, consult a doctor promptly to identify the cause and carry out targeted treatment.
