Anyone noticing signs of an over- or underactive thyroid should get checked, like a noticeable lump, unintended weight changes, extreme fatigue, hair loss, or feeling unusually hot or cold. It also matters if you're pregnant or trying to conceive. Thyroid symptoms mimic other conditions, so diagnosis matters. No referral needed.

It depends on the type. Hyperthyroidism often comes from Graves' disease, thyroid nodules, or too much iodine. Hypothyroidism is usually traced to Hashimoto's disease or iodine deficiency, which can also enlarge the thyroid into a goiter. A proper diagnosis pins down the cause. No referral needed to come in.

Thyroid disease falls into two main groups. Hyperthyroidism is an overactive thyroid making too much hormone, which can cause a fast heart rate, weight loss, trouble sleeping, and anxiousness. Hypothyroidism is underactive, with fatigue, weight gain, constipation, and dry skin. A clear diagnosis points you to the right treatment.

It’s a common misconception that thyroid pills make you gain weight. The goal of thyroid medications is to regulate your metabolism to prevent weight gain. You should continue your medications and speak with your physician if you have concerns about gaining weight while on thyroid medicine.

While regular exercise, maintaining a healthy weight, and managing stress are great for your overall health, they don’t directly affect your thyroid. The key factor for thyroid health is ensuring you consume the right amount of iodine. Foods like fish, healthy fats, dairy, and eggs can help you meet the daily recommended 150 mcg of iodine.

Thyroid nodules are very common, with about one in ten people having one. The good news is that nine out of ten nodules are benign. If you notice a goiter or feel a nodule, it’s important to see a doctor to rule out thyroid disease or other potential issues.

Because your thyroid affects many of your other body functions, complications can arise if your thyroid disease is left untreated or if you’re not following your treatment plan. Depending on your thyroid condition, complications may include: Atrial fibrillation (AFib) Congestive heart failure Stroke Osteoporosis Depression Increased risk of heart disease Fertility issues

No, most thyroid diseases are caused by genetics or autoimmune disorders, which are not preventable. The only condition you may be able to prevent is an iodine deficiency or excess. Talk with your physician about ways to ensure you manage your iodine intake.
