hyperthyroidism and cysts

Hello! I am 43 years old female. Through my life I have rarely suffered from diseases or illnesses and the problem I have now comes as a shock to me. In my neck ( front ) I have developed a cyst. It grew pretty much and is soft. I don’t have any additional problems like hoarseness or difficulty swallowing but I certainly don’t like the look of it. I am wondering if this cyst means I have a hyperthyroidism. I would appreciate all the info you have! Thank you in advance!

Hello! This may not even be a cyst as cysts are filled with fluid, and other thyroid nodules are filled with thyroid tissue. A person can develop nodules when thyroid hormone levels are normal, elevated, or decreased. So, thyroid nodules don’t necessarily mean you have hyperthyroidism. But, if you don’t have any other symptoms, your thyroid hormones are probably normal as increased and decreased thyroid hormones usually show symptoms. However, you should do some tests. So, make sure you visit a doctor soon.
