Introduction

If the tongue appears swollen with tooth marks on the edges, accompanied by poor appetite, abdominal distension, loose stools, and general fatigue, it is often due to spleen deficiency. Spleen deficiency leads to impaired transformation and transportation, resulting in internal accumulation of dampness and swelling of the tongue. If tongue swelling is also accompanied by symptoms such as soreness and weakness in the lower back and knees, cold intolerance, increased nocturnal urination, dizziness, and tinnitus, it may be related to kidney deficiency.

Generally, a swollen tongue is often associated with spleen deficiency. If significant kidney deficiency symptoms are also present, it may be related to kidney deficiency; a comprehensive evaluation of overall symptoms is necessary. If in doubt, early medical consultation is recommended. Detailed analysis is as follows:

If the tongue is swollen with teeth marks on the edges, accompanied by poor appetite, abdominal distension, loose stools, and body fatigue, it is usually due to spleen deficiency. Spleen deficiency leads to impaired transformation and transportation functions, causing internal accumulation of dampness and swelling of the tongue.

If a swollen tongue is accompanied by symptoms such as soreness and weakness of the waist and knees, cold intolerance with cold limbs, frequent clear urination, and mental fatigue, it may be related to kidney deficiency. The kidneys govern water metabolism; when kidney deficiency occurs, fluid regulation becomes impaired, leading to fluid retention and a swollen tongue.

A comprehensive assessment combining systemic symptoms is necessary for accurate diagnosis; a conclusion should not be drawn based on a single symptom alone. If tongue swelling persists and is accompanied by significant discomfort, prompt medical attention is advised.
