Can lithium cause weight loss?

I was told by my doctor that lithium usually causes weight gain, so I am a bit confused. Is weight loss also a common thing? I just started this medication and I am really worried about how my body will change.

In my long life, I have seen that different bodies react uniquely to psychiatric medicines. While weight gain is typical with lithium, some people do experience weight loss, especially if they have thyroid changes or stomach issues initially. Don't worry, just keep your doctor informed.

I know how frustrating it is when your weight starts fluctuating on these heavy medications. When I had appetite issues, I used to drink ginger tea and eat small, frequent home-cooked meals to keep my digestion stable. But if you are losing too much weight, a doctor's advice is a must.

Since lithium can affect the thyroid, any sudden change in weight should be checked out immediately. If it triggers hyperthyroidism (which is rare but possible), it can cause weight loss. Please get your TSH and lithium levels checked and discuss it with your specialist.

Lithium typically causes water retention and weight gain for most people, but some might lose weight due to side effects like a metallic taste or nausea. If your health allows, keep up with a structured routine of walking and eating balanced meals to keep your metabolism steady.

Usually, people talk about weight gain with this medicine, so weight loss is thoda unusual. Make sure you are not skipping meals because of nausea or loss of taste. Try to eat nutrient-dense vegetarian foods like nuts, paneer, and dals to maintain your strength, and talk to your doctor.
