Jaggedness on both sides of the tongue may be caused by Spleen-Qi deficiency, Spleen deficiency and Dampness (weakness of the Spleen and retention of Dampness). However, the exact cause needs to be determined by the patient’s other symptoms. In patients with Spleen-Qi deficiency, in addition to serrations on both sides of the tongue, they may also have symptoms such as abdominal distension, decreased diet, loose stools, emaciation, tiredness of limbs, fatigue (mental exhaustion, physical weakness), and lack of qi and laziness (lack of strength, not wanting to talk). Spleen deficiency and dampness patients, in addition to the tongue on both sides of the jagged, will also be accompanied by a reduced diet, fullness of the stomach and epigastrium, loose stools, or even nausea and vomiting, or thirst for hot beverages, body fatigue, or even swelling, and so on. If the symptoms of jagged tongue are not relieved for a long time or accompanied by other discomforts, consult a doctor in time to identify the cause and carry out targeted treatment.
