7Smoking
Some studies have shown some shreds of evidence that smoking might increase the risk of developing goiter, no matter how many cigarettes you smoke. This cause is more common in older people and women. The elderly often have multinodular goiters, while young women are likely to have diffuse thyroid enlargement. However, the exact reason is still unknown and further research is needed to learn more about this association. The risk can be highest in those individuals with a deficiency of iodine. By stop smoking, you can reduce the risk or improve your symptoms. [7]
