About the Seeds of Change initiative
Welcome to Seeds of Change in the UK.
Seeds of Change is an initiative that brings together and empowers people impacted by hypoparathyroidism (also known as hypopara). Inspired by nature, gardens and the outdoors, Seeds of Change captures the positive concept of taking action today for a brighter tomorrow.
Whether you are living with, know someone living with or are caring for someone with hypopara, we hope that by shining a light on this condition and community, you will feel empowered and ready to advocate for improved care and quality of life.
Our Partners
We are proud to work alongside Parathyroid UK and the Society for Endocrinology on the Seeds of Change initiative. Find out more about each organisation below:

Parathyroid UK
Parathyroid UK is a charity for people living with rare and hidden parathyroid disorders, just like hypoparathyroidism. It is the only patient organisation in the UK and Ireland devoted specifically to their needs. They are dedicated to patient-centred support, advocacy, and education for those affected by both rare hypoparathyroidism and more common hyperparathyroidism conditions. Their work includes raising awareness, campaigning for improved care, and bringing together healthcare professionals to advance research and create vital resources.

Society for Endocrinology
The Society for Endocrinology is a professional membership organisation that supports scientists, clinicians, and nurses throughout their careers in the field of hormone science. They actively engage with policymakers, journalists, patients, and the public to promote informed health decisions and showcase the importance of endocrinology. Their mission is to advance scientific and clinical education and research in endocrinology while raising its profile across the UK.
What is Hypopara?
Hypopara is a rare endocrine disease, caused by insufficient levels of parathyroid hormone (PTH) in the body.1 The parathyroid glands lie behind the thyroid gland in the neck. They produce PTH, which plays a major role in regulating the body’s blood levels of calcium and phosphorus by acting directly on bones and kidneys and indirectly on the intestine.2,3 If the parathyroid glands are removed, destroyed, or defective, this may lead to insufficient levels of PTH.2,4
Hypopara may result from:2,5

Recognising Symptoms
Hypopara affects numerous systems in the body and is associated with a range of short-term symptoms and long-term complications. These include neuromuscular irritability, kidney complications, calcification outside of the bone, and cognitive impairment.2,4,6 Below are some of the body systems where an imbalance of PTH levels may have an impact, , along with potential signs and symptoms*:4

*These manifestations are mostly the result of management with calcium and active vitamin D rather than the disease itself.
Living with Hypopara
People with hypopara may experience a range of physical, cognitive and emotional symptoms that may impact their employment, personal and social lives, and overall well-being.7,8
The management of hypopara can be associated with substantial economic burdens, and consequences of hypoparathyroidism may negatively impact employment status and work productivity.3,7

The insights used to inform this below video have been taken from the qualitative responses gathered from a patient survey conducted in partnership with Ascendis Pharma UK and Parathyroid UK in 2024.9 Data was reported on an aggregate level and data was provided anonymously.
The Hypopara Butterfly
Hypopara is sometimes visually represented as a butterfly, which has become a recognised symbol of thyroid awareness. Butterflies are universally understood to signify change and hope for those living with a challenging condition.
The connection between seeds and butterflies in nature take this one step further. Seeds represent the beginning of life and future potential. Butterflies symbolise freedom, transformation, and new beginnings. Together, they convey the idea of starting small – like a seed – and evolving into something beautiful and free, like a butterfly.
Just as a butterfly undergoes a profound transformation in its lifecycle, people living with hypopara experience their own journey learning to recognise the symptoms and highs and lows of living with the condition.
During 2025, the Hypopara Butterfly will be revealed in the UK as an inspiring butterfly mural that brings to life the challenges and hopes associated with hypopara.
