Autoimmune Attack: The Most Common Culprit
Hashimoto's thyroiditis, an autoimmune disorder, is the leading cause of hypothyroidism in iodine-sufficient areas. It's like your immune system declaring war on your thyroid gland. Over time, this friendly fire damages the thyroid, reducing its ability to produce hormones. While we don't fully understand why this happens, genetics and environmental factors likely play a role.
Iodine: A Delicate Balance
Iodine is crucial for thyroid function, but too much or too little can cause problems. Iodine deficiency is the most common cause of hypothyroidism worldwide, especially in mountainous regions. Surprisingly, excessive iodine intake can also trigger hypothyroidism in some people, particularly those with underlying thyroid issues. It's like overwatering a plant - sometimes too much of a good thing can be harmful.

Medical Treatments and Medications
Some medical treatments can inadvertently lead to hypothyroidism. Radioactive iodine therapy or surgery for hyperthyroidism often results in an underactive thyroid. Certain medications, like lithium for bipolar disorder or amiodarone for heart rhythm problems, can interfere with thyroid function. Even some cancer treatments, such as checkpoint inhibitors, can affect the thyroid.
