Cases of lead poisoning due to the use of Ayurvedic medicines demonstrate the importance of patient medical history in diagnosis and the need for public health cooperation to prevent similar risks.
Article CMAJ (Canadian Medical Association Journal) highlights a case of lead poisoning from an Ayurvedic drug in a young woman and the complexity of diagnosing this rare condition.
“Given that lead toxicity is rare and its symptoms are non-specific, patients are often seen by many health care providers before a diagnosis is made,” said Dalla Lana Public Health, University of Toronto. Dr. Julian Gitelman of the Graduate School writes with co-authors. “A careful exposure history is essential to suggest a diagnosis.”
ayurvedic medicineAlso known as Ayurveda, it is one of the world’s oldest holistic healing systems. Originating in India more than 3,000 years ago, it is based on the belief that health depends on a balance between mind, body, and spirit. Ayurveda emphasizes the importance of maintaining this balance through diet, herbal remedies, meditation, yoga, and other lifestyle practices. Its approach to health is tailored to an individual’s unique constitution or “dosha” with the aim of treating the root cause of symptoms and promoting long-term health.
Patient case and diagnosis
The patient was a 39-year-old woman who presented to the emergency department three times in a six-week period with abdominal pain, constipation, nausea, and vomiting. On her third visit, she was admitted for anemia and possible gastrointestinal bleeding. Many invasive investigations revealed no cause for her symptoms.
At a follow-up visit a few weeks later, she reported that she had been taking Ayurvedic medicines daily for over a year to treat her infertility. Her blood lead level was high at 55 µg/dL, and the normal value was less than 2 µg/dL. The patient discontinued Ayurvedic treatment and started chelation therapy. Her blood lead levels decreased and her symptoms resolved.
Public health response and investigation
Once the diagnosis of lead toxicity was made, the medical team contacted Public Health Ontario (PHO) and tested 17 pill samples provided by the patient. After testing revealed that most of the tablets contained high levels of lead, the PHO engaged the local public health authority that regulates natural health products, the Toronto Public Health Agency, and Health Canada. I did. As a result of a joint investigation by an Ayurvedic clinic, hundreds of tablets were seized due to violation of regulations. Regulations regarding natural health products. Health Canada and Toronto Public Health have both issued public advisories warning people that this particular company’s products pose a health risk.
The authors emphasize the importance of communication and collaboration between clinicians and public health to minimize the health risks of lead in consumer products. “A recent systematic review of case reports on lead poisoning found that traditional and herbal medicines were common causes,” the authors write. “Heavy metals are sometimes added intentionally for perceived healing properties.”
“When a consumer product may be contaminated with lead, or when lead exposure is associated with a community source, public health can be involved to identify other people at risk. “This may encourage broader actions to reduce and prevent human exposure,” the researchers concluded.
