Identifying these signs in time is key for early diagnosis and treatment. Below, we will explore the 10 main thyroid symptoms, including symptoms of an inflamed thyroid and discomfort in the throat.

“Brain fog” is a common symptom in people with thyroid problems (both hypothyroidism and hyperthyroidism). It may manifest as:

10. Swelling in the neck and throat problems
The enlargement of the thyroid gland, known as multinodular goiter, can cause discomfort in the neck area. Thyroid symptoms in the throat include:
- Visible swelling in the neck.

- Difficulty swallowing or a feeling of pressure in the throat.
“Thyroid symptoms may go unnoticed, but if you experience fatigue, unexplained weight changes, or throat discomfort, it is essential to consult a specialist for early diagnosis”
When should you consult a specialist?
If you experience any of these thyroid symptoms, it is important to visit a Thyroid and Endocrine Surgery specialist. A simple blood test can determine if there is an alteration in thyroid hormone levels. In cases of thyroid nodules, additional studies will be necessary to rule out possible complications, including thyroid cancer.
