Lithium is an effective medicine for bipolar disorder, but during pregnancy, it must be used with careful medical supervision. Studies show a small increased risk of heart defects in the baby, particularly a rare condition called Ebstein anomaly (affects the tricuspid valve, which controls blood flow on the right side of the heart), mainly when lithium is taken during the first trimester. Some newborns may also have temporary problems such as feeding difficulty, low muscle tone, or thyroid and kidney issues after birth. Because of these risks, doctors monitor lithium blood levels closely during pregnancy, as they can change with fluid balance and kidney function. In some women, lithium may still be continued if the benefits outweigh the risks, but this decision must be guided by a specialist. Alternative options may include certain antipsychotic medications, such as quetiapine or olanzapine, or lamotrigine for mood stability in selected cases. Medicines like valproate are usually avoided in pregnancy due to the higher risk of birth defects. Careful planning before conception and regular prenatal check-ups, including heart scans of the baby, are very important.

A slightly low serum lithium level means that the amount of lithium in your blood is below the usual therapeutic range needed to effectively control mood symptoms. This may happen if a dose is missed, the dose is too low, or due to factors such as changes in kidney function, fluid intake, or interactions with other medicines. It is important not to adjust or stop your medication on your own. You should discuss this result with your doctor or psychiatrist. Your doctor may ask how regularly you take your medication and check for any recent changes in your routine, diet, or other medicines. Based on this, they might adjust your lithium dose or repeat the blood test to confirm the result. It is also important to continue regular monitoring of kidney function and thyroid function while on lithium. Taking the medicine at the same time each day and staying well hydrated can help maintain stable levels.

Bipolar disorder is a long-term mental health condition that affects mood, causing episodes of depression and sometimes periods of unusually high energy or mania. Medicines such as lithium and quetiapine help to stabilise mood and reduce the risk of relapse. For many people, treatment is needed for a long time, and some may need to continue medicines for many years or even lifelong to stay well. This is because stopping treatment too early can increase the chance of symptoms returning. However, with proper treatment, most people can still live a normal and fulfilling life, including working, studying, and maintaining relationships. Along with medicines, regular sleep, reducing stress, and psychological support also play an important role in staying stable. In some cases, if a person remains stable for a long time, a doctor may review and adjust the treatment. However, any change or stopping of medicines should always be done under medical supervision. Regular follow-up with your doctor is essential to maintain stability and prevent future episodes.
