The first World Hormone Day takes place on April 24th to raise awareness of the vital role of hormones in rare and chronic disease. Under the banner of #BecauseHormonesMatter, the campaign brings together the global endocrine community to share the small steps everyone can take to improve hormone health and to raise awareness of the signs of endocrine disease.

The Pituitary Foundation joins the European Society of Endocrinology (ESE), the European Hormone and Metabolism Foundation (ESE Foundation), and partners worldwide to put hormones in the spotlight. Building on the success of European Hormone Day over the last three years, this new global event calls for action to put hormones at the forefront of public health conversations.

Why we’re supporting #BecauseHormonesMatter

The pituitary gland plays a key role in producing important hormones, like cortisol, growth hormone, oxytocin and more. It is often referred to as the ‘master gland’ because of its essential role in hormone production. This World Hormone Day, we’re putting the pituitary in the spotlight and highlighting the role of pituitary hormones in health and disease.

Hormones and pituitary conditions

Around 70,000 people in the UK live with a pituitary condition, yet delays in diagnosis and treatment are common partly due to lack of awareness of these conditions and their symptoms. To combat this, we want to help everyone recognise the early signs and symptoms of endocrine disease.

These include:

  1. Unexplained weight gain/loss
  2. Sensitivity to cold
  3. Changes in appetite
  4. Brittle hair and nails
  5. Fatigue
  6. Dry and flaky skin
  7. Onset of depression
  8. Excessive thirst
  9. Signs of early or late puberty (outside ages 8-13 in girls and 9-14 in boys)
  10. Adult-specific: loss of libido, irregular menstrual cycles, infertility
