Hormones matter to everyone
Many people have an idea of what hormones are, but do not really know what hormones do or how individuals can improve their endocrine (hormone) health.
ESE works with many medical professionals, patient groups and national endocrine societies to improve diagnosis and treatment. This includes raising awareness of the vital role hormones play in health and disease. For example, our videos below provide information about why hormones matter and what you can do to improve your hormone health.
We also have infographics that explain You Endocrine System and suggest 10 Recommendations for Good Hormone Health. You'll find more graphics in our Patient Zone.
The annual World Hormone Day focuses on raising public awareness. You can join in on social media using the hashtag #BecauseHormonesMatter. Keep an eye out for activities led by national societies and patient groups in your area!

Hormones are biological messengers that travel throughout the body, telling cells and tissues what to do. When they are out of balance or fail, this can lead to the development of prevalent chronic diseases such as diabetes, thyroid disorders, cancer, osteoporosis and obesity, and other health challenges such as infertility. There are also more than 440 rare endocrine conditions that affect millions of people in Europe, but often go undetected.

Endocrinology is the study of hormones, which are essential for health and wellbeing. In this patient information video, some of our clinical experts discuss the role of the endocrine system and organs in health and disease.
