ICD-10: E67.2

Megavitamin-B6 syndrome, classified under ICD-10 code E67.2, refers to a condition resulting from excessive intake of vitamin B6 (pyridoxine). This syndrome is characterized by a range of symptoms that arise due to the toxicity associated with high doses of vitamin B6, which is often taken in supplement form.

Clinical Description

Definition and Causes

Megavitamin-B6 syndrome occurs when an individual consumes vitamin B6 in amounts significantly exceeding the recommended dietary allowance (RDA). While vitamin B6 is essential for various bodily functions, including amino acid metabolism, neurotransmitter synthesis, and the production of hemoglobin, excessive intake can lead to adverse effects. The syndrome is typically associated with the use of high-dose vitamin B6 supplements, often taken for conditions such as depression, carpal tunnel syndrome, or other neurological disorders.

Symptoms

The symptoms of Megavitamin-B6 syndrome can vary but commonly include:

• Neuropathy: One of the most notable effects is peripheral neuropathy, which manifests as numbness, tingling, or pain in the extremities. This is due to nerve damage caused by high levels of pyridoxine.
• Sensory Disturbances: Patients may experience altered sensations, including heightened sensitivity to touch or temperature changes.
• Gastrointestinal Issues: Symptoms may also include nausea, abdominal pain, and diarrhea.
• Fatigue and Weakness: General feelings of tiredness and muscle weakness can occur.
• Mood Changes: Some individuals report mood swings or changes in mental status, potentially linked to the role of vitamin B6 in neurotransmitter synthesis.

Diagnosis

Diagnosis of Megavitamin-B6 syndrome is primarily clinical, based on the patient's history of vitamin B6 supplementation and the presence of characteristic symptoms. Laboratory tests may be conducted to measure serum levels of vitamin B6, but these are not always necessary for diagnosis. The ICD-10 code E67.2 is used for billing and documentation purposes in healthcare settings.

Treatment

The primary treatment for Megavitamin-B6 syndrome involves discontinuing the excessive intake of vitamin B6. In most cases, symptoms improve once the source of excess vitamin B6 is removed. Supportive care may be necessary for managing symptoms, particularly neuropathy, which can take time to resolve.

Conclusion

Megavitamin-B6 syndrome, represented by ICD-10 code E67.2, highlights the importance of adhering to recommended vitamin intake levels.
