Will taking Euthyrox cause weight gain?

Levothyroxine sodium tablets, also known as Euthyrox, generally do not cause weight gain if the dosage is appropriate and thyroid function is normal. However, insufficient dosage leading to uncorrected hypothyroidism may result in weight gain. If any abnormalities occur, timely medical consultation is recommended. Detailed analysis is as follows:

With an appropriate dosage of levothyroxine sodium tablets, the body's thyroid hormone levels can be maintained at normal levels, ensuring a stable metabolic rate and balance between energy consumption and intake. Thus, weight will not experience abnormal changes due to the medication. Most people can maintain a healthy weight for a long time under such conditions, with no significant fluctuation compared to before medication.

If the dosage of levothyroxine sodium tablets is inadequate and hypothyroidism remains unimproved, persistent hormone deficiency will slow down the metabolic rate and reduce calorie consumption. Even without an increase in food intake, excess energy will be converted into fat, leading to weight gain and a plumper body shape. This may also be accompanied by symptoms such as fatigue, cold intolerance, and dry skin.

Regular thyroid function tests are necessary while taking levothyroxine sodium tablets, and the dosage should be adjusted according to medical advice. At the same time, maintaining a balanced diet and moderate exercise is important to prevent abnormal weight changes.
