The thyroid gland is a small butterfly-shaped gland located in the middle of the lower neck, it’s responsible for a number of cell functions - from regulating your metabolism to balancing your breathing and heart rate. With these crucial roles in mind, when your thyroid isn’t functioning as it should, it can cause a range of symptoms, including fatigue, weight changes, and muscle weakness, which can greatly impact your day to day life. This is why it’s so important to stay in the know when it comes to your thyroid health.

Thyroid Health: What you Should Know

It’s estimated that over 20 million people in the United States have some form of thyroid condition - almost 60% of these people have no idea [2]. Thyroid disorders can result in a range of symptoms, some of which can cause serious health complications, such as goiter or heart problems. This is more commonly seen in those with undiagnosed thyroid disorders, as these people will not be receiving proper treatment and management of their condition. For this reason, it’s easy to understand why early diagnosis and regular testing are key.

Hypothyroidism causes

  • Hashimoto's disease
