Does synthroid cause weight loss?

I recently started on Synthroid for my underactive thyroid. I've heard some people say that managing thyroid can lead to weight loss. Does Synthroid actually cause weight loss, or is that not typically the case?

I can only speak from my own journey, but once my doctor put me on the correct dose of Synthroid, I slowly lost about 5 kgs of water weight and bloating. My metabolism had completely shut down before that, so the medicine just brought my body back to its normal state.

Thyroid medicine must be taken exactly as the doctor says, first thing in the morning on an empty stomach. Along with the pill, you can drink warm water with coriander seeds soaked overnight to support your thyroid naturally. Regular routine is very important for health.

Yes, it causes weight loss but only if you actually have hypothyroidism. The medicine replaces the hormone your body is lacking, which restores your normal metabolic rate. Don't expect dramatic weight loss overnight, it takes about 6-8 weeks of consistent usage to see changes.

It definitely helped me shed the stubborn puffiness around my face and ankles! Once your thyroid levels are back in the green zone, losing weight becomes much easier. Just keep a healthy diet and stay happy! 😊

I ignored my extreme fatigue and sudden weight gain for two years, thinking it was just stress. When I finally got checked, my TSH was over 50. Please get your thyroid levels tested properly before expecting any medicine to solve your weight issues.

Hello, I was recently diagnosed with mild hypothyroidism and prescribed this medicine. I am hoping to lose some weight that I gained recently. Does the weight loss happen automatically, or do I need to strictly diet as well? Thank you so much.
