Hi, I have gone through your question & understand your concern. As your thyroid gland is removed surgically, it means you are hypothyroid. If you do not take levothyroxine, you can have serious consequences. It will decrease your metabolic rate leading to weight gain, lethargy, weakness, sleepiness, hair loss, increased sensitivity to cold, dry skin, impaired memory, slow heart rate & constipation. So do not skip your medication. I hope, my answer will help you. Regards, Dr. Maria Daud
