Which complication can arise from the ingestion of activated charcoal?

Activated charcoal is a common treatment used in the emergency management of certain types of poisoning or overdose. While it can effectively bind to various toxins in the gastrointestinal tract and prevent their absorption into the bloodstream, one of the complications that can arise from its ingestion is bowel obstruction. This occurs particularly if the activated charcoal is given in large amounts or in individuals with pre-existing gastrointestinal conditions that inhibit proper movement through the intestines.

Bowel obstruction can manifest through symptoms such as abdominal pain, bloating, vomiting, and the inability to pass stool. It's critical for EMTs and medical personnel to be aware of this potential risk, particularly when administering activated charcoal in a clinical setting. Proper dosing and monitoring can help mitigate this risk.

Other complications listed, such as hypertension, seizures, and diabetic coma, are not commonly associated with the ingestion of activated charcoal. They are more likely related to the underlying conditions prompting the activated charcoal treatment, rather than being direct side effects of activated charcoal itself. Therefore, recognizing bowel obstruction as a complication emphasizes the need for careful assessment and monitoring of patients receiving this treatment.
