2. Mood Changes
The Mayo Clinic explains that thyroid issues can impact your mood for the worse – namely, you can experience anxiety and depression. Mood changes can occur whether your thyroid is overactive (hyperthyroidism) or underactive, it adds.
For example, hyperthyroidism is connected to “unusual nervousness,” restlessness, and irritability, while an underachieving thyroid can usually lead to depression, explains the source.
