It is essential to differentiate vertigo of excess type from that of deficiency type. The excess type is usually caused by both hyperactivity of liver yang and retention of turbid phlegm and induced by emotional depression and anger; it is characterized by a short course or intermittent episodes, severe dizziness with a rotatory feeling accompanied by nausea, vomiting and salivation and often found in those with strong physique. Deficiency of blood or insufficiency of kidney essence often contributes to deficiency type which is characterized by a long course, intermittent or persistent occurrence and is induced or aggravated by overstrain; it is also manifested as dizziness and heavy sensation in the head with no rotatory feeling, and general debility as well.

Essentials for Diagnosis 
(1) The chief manifestations are dizziness and blurred vision. The mild case can be relieved by closing one's eyes; the severe case is characterized by a rotatary feeling like sitting in a sailing boat or moving car, even fainting.

(2) There may be accompanying symptoms such as nausea, vomiting, nystagmus, tinnitus, deafness, sweating and pale complexion.

(3) Slow onset, gradual aggravation, or repeated attacks.

(4) To make a clear diagnosis, hemoglobin, red cell count, blood pressure, electrocardiogram, cervical vertabrae X-ray radiography, Doppler transcranial ultrasonic examination, CT and MRI examinations may be done.

In TCM, a disease or a symptom might be caused by one pathogenic factor, even two or three pathogenic factors. When diagnosing a disease or a symptom, TCM doctors must follow the principle of "Syndrome Dfferentiation", and then "Suit the Remedy to the Case". In order to gain a more definite and valuable diagnosis, it's important and necessary for the doctor to learn the detailed health information of the patient, including his/her disease duration, age, sex, height, weight, family history, urine, stool, diet, sleep, sweat, energy, mood (emotion), as well as the tongue conditions and the palm conditions, etc. If you would want our expert to create a TCM diagnosis, you're welcome to contact us.
