A 38 year-old female came to me with "progressive fatigue and limb pain for more than 4 months".
Symptoms gradually increased to the point that she could not even tolerate a short distance of walking.
I thought of Toxicant test on the patient’s urine ( given her prior flawless routine reports) to exclude the poisoning caused by physical or chemical intoxication which showed that urine mercury level were significantly elevated
In order to further identify the source of the poison and the mercury concentration changes in the hair in the past six months, a strand of proximal hair of about 13 cm, was taken.
According to the test results and the hair growth rate of 1-1.5 cm per month, it could be estimated that the mercury content in the measured hair would be the highest from July to September 2020, and there was a trough from November to December 2020, and then it rose again.
Following this pattern, I asked the patient about her daily contacts and environmental history. After careful recollection, she recounted that she purchased a kind of cosmetic online about half a year ago (May 2020). Her symptoms started after using it for more than two months. Since the symptoms were mild and this did not bring to her attention. She began to see a doctor in September 2020 due to severe symptoms.
Her condition was severely affecting her daily life, so she rarely used those cosmetics from November to December of that year, then the symptoms were slightly relieved. However, she resumed using them again and the symptoms worsened. This cosmetic was mailed to a Beijing poison testing center, and the result showed that the mercury content was 9856.2 µg/g (allowable limit value <1µg/g).
PS: You're naturally beautiful !
