Does levothyroxine cause weight gain or weight loss?

I just started Levothyroxine for my thyroid imbalance, and I'm a bit confused about its effect on weight. Does this medication usually cause weight gain or weight loss?

I was reading up on this because my sister just got diagnosed with hypothyroidism. From what I understand, levothyroxine should actually help you lose weight because it speeds up a slow metabolism. But I guess if the dose is too low, you might still struggle with weight gain.

Levothyroxine is a hormone replacement therapy, so its effect on weight depends entirely on your dosage. An underdose might cause persistent weight gain, while an overdose could lead to hyperthyroidism and weight loss. It is crucial to have your doctor evaluate your TSH levels to find the sweet spot.

Along with taking your prescribed morning pill, drinking coriander seed water can help with thyroid health. However, you cannot manage your weight or thyroid levels solely with home tips. If your weight is fluctuating drastically, please consult your doctor for a dose check.

I always get so stressed out reading about hormone medicines and their side effects. I kept checking my weight twice a day when my doctor prescribed this, fearing the worst. But honestly, it usually helps stabilize your weight once your body gets used to the correct dosage.

Do not worry too much about these physical changes; focus on healing your body from within. Levothyroxine is just helping your system find its natural balance, which will eventually stabilize your weight. Stay positive, eat clean, and trust the medical process.

I love my pani puri and biryani too much to blame only my thyroid pill for weight issues! Levothyroxine actually helps improve your metabolism so you can process food better. Just don't use it as an excuse to ignore healthy eating habits like I sometimes do.

When my 12-year-old was started on thyroid medication, his weight had been rising rapidly. After three months of the correct levothyroxine dosage, his weight stopped climbing and gradually normalized. It helps with weight loss if your body actually needs the hormone.
