Thyroid & Hormones
The thyroid is small, but when it runs too fast or too slow you can feel it everywhere. Studies here look for better ways to diagnose and treat it.

- Underactive thyroid
- Overactive thyroid
- Thyroid eye disease
- Thyroid nodules
- Adrenal conditions
What studies here look at
Some thyroid studies test whether a new medicine or a different dose of an existing one helps people who still feel unwell on standard treatment. Others look at overactive thyroid and at thyroid eye disease, which can make the eyes bulge, feel gritty or see double.
Research also covers lumps in the thyroid, testing ways to tell which ones need surgery, and conditions of the adrenal and pituitary glands, which are rarer and often have fewer studies open at once.
Who studies often look for
People on thyroid tablets who still feel tired or unwell
Adults with an overactive thyroid, including Graves’ disease
People whose eyes have changed because of their thyroid
Adults who have been told they have a thyroid nodule
Each study sets its own requirements. Read this as the people who tend to be asked, not as a checklist.
