Lithium works by calming the brain’s overactive signals and strengthening the weaker ones, so mood stays steady instead of swinging between highs and lows. It acts like a balance keeper, preventing the brain’s “messages” from becoming too loud or too quiet, which helps control mood changes in people with bipolar disorder.

Lithium is a mood stabilizer used mainly for bipolar disorders to prevent mood swings. It works by balancing brain signals to keep moods steady. Doctors also use it to reduce suicide risk and sometimes to boost antidepressants. Common side effects are thirst, frequent urination, tremors, and stomach upset, while high levels can cause confusion, severe shaking, kidney, or thyroid problems. Because the safety range is narrow, regular blood tests are needed. While using the medicine, water intake should be high, since dehydration or heavy sweating can raise lithium levels, while too much caffeine can lower its effect. In short, lithium is effective but requires careful monitoring.
