Final answer:
The most likely cause of sudden strider 24-96 hours after thyroidectomy is Graves' disease, which is characterized by overproduction of thyroid hormones.
Step-by-step explanation:
The most likely cause of sudden strider 24-96 hours after thyroidectomy is Grave's disease, which is characterized by overproduction of thyroid hormones. This excess thyroid hormone can lead to an increased basal metabolic rate (BMR), resulting in symptoms such as weight loss, rapid heart rate, and difficulty sleeping. Graves' disease is caused by long-acting thyroid stimulator (LATS) and LATS protector, which mimic the action of thyroid-stimulating hormone (TSH).
