A thick neck is not necessarily caused by hyperthyroidism. While a swollen neck is commonly seen in hyperthyroidism, it may also result from obesity, or from thyroid enlargement due to tumors or local inflammation in the thyroid area. Patients should visit a正规 hospital for examination to determine the exact cause of the neck thickening and receive appropriate, targeted treatment.
