Which symptoms are associated with acute lithium toxicity?

• A. Nausea, vomiting, diarrhea
• B. Tremors
• C. Confusion
• D. Weight gain

Answer: (A)

Acute lithium toxicity often begins with gastrointestinal symptoms because a rapid rise in lithium level irritates the GI tract directly. Nausea, vomiting, and diarrhea are common early signs as the drug accumulates after ingestion. Tremors and confusion are CNS symptoms that can develop as toxicity progresses to higher levels, but they are not the initial presentation in an acute exposure. Weight gain is more associated with long-term use rather than an acute toxic event. When GI symptoms suggest possible lithium excess, it’s important to check the serum lithium level and assess hydration, coordinating with a clinician to adjust or pause the medication as needed.
