Which symptoms are associated with lithium toxicity?

Lithium is a mood stabilizer commonly used in treating bipolar disorder, and its therapeutic range is narrow. This means that the difference between a therapeutic dose and a toxic dose is quite small. When lithium levels become elevated, various symptoms of toxicity may arise.

The symptoms associated with lithium toxicity include tremors, nausea, and vomiting. Tremors can occur as a result of lithium affecting the nervous system, leading to involuntary muscle movements. Nausea and vomiting often arise due to gastrointestinal irritation or the body's reaction to elevated lithium levels. Recognizing these symptoms is crucial for early intervention, as severe lithium toxicity can lead to more serious complications, including renal impairment and neurological dysfunction.

Understanding the associated symptoms can help in assessing a patient who is on lithium therapy, especially if they present with signs of toxicity. The other listed symptoms, such as headaches, fatigue, or confusion, may occur in various clinical situations but are not specific indicators of lithium toxicity.
