Hypoparathyroidism in Australia: A Guide for the Newly Diagnosed
Hypoparathyroidism is a rare, long-term condition in which the body does not make enough parathyroid hormone, causing low blood calcium. If you have just been diagnosed in Australia, CaSR Patient Support offers free peer support, a national patient community and trusted information, so you never have to face it alone.

What is hypoparathyroidism?
Hypoparathyroidism happens when the parathyroid glands (four small glands in your neck) do not make enough parathyroid hormone, or PTH. PTH is the hormone that helps keep the calcium in your blood at the right level. When there is not enough of it, blood calcium can fall too low.
A helpful way to picture this is a thermostat. Your body is meant to sense calcium and adjust it automatically to keep it in balance. In hypoparathyroidism, that balance is harder to maintain, which is why the condition needs ongoing care from a doctor.
Some people develop hypoparathyroidism after neck or thyroid surgery. Others have a non-surgical or genetic form. One genetic cause involves the calcium-sensing receptor (CaSR), which leads to a condition called ADH1 (autosomal dominant hypocalcaemia type 1). Whatever the cause, the day-to-day experience of living with low calcium is something our community understands well.

You are not alone
A diagnosis of a rare condition can feel isolating, especially when friends, family and even some healthcare providers have never heard of it. That feeling is completely understandable, and you are not the only one experiencing it.
Hypoparathyroidism is rare, but there is a whole community of Australians living with it and related calcium-sensing receptor disorders. Based on international prevalence of 6.4 to 37 per 100,000, up to 10,000 Australians are estimated to be affected. No Australia-specific prevalence study has been published. Connecting with people who genuinely understand what a low-calcium day feels like, the tingling, the cramps, the fatigue, the brain fog, can make an enormous difference to how supported you feel.
CaSR Patient Support exists to bring that community together, share reliable information, and make sure no one in Australia has to work it all out on their own.

- Peer support. Connect with other Australians living with hypoparathyroidism and calcium-sensing receptor disorders, so you can share experiences and practical tips with people who get it.
- A national patient community. Whichever state or territory you are in, you can be part of an Australia-wide community that understands your condition.
- Trusted information. Clear, patient-friendly information about your condition, written to be easy to understand and reviewed for accuracy.
- Treatment access advocacy. We advocate for Australians to have timely access to new and emerging treatments.
You do not need to be an expert, and you do not need to have all the answers. You just need to reach out.

Getting involved and the patient registry
One of the most powerful things you can do after a diagnosis is add your voice to the community. When you join CaSR Patient Support, you become part of a national patient community that helps us understand how many Australians live with these conditions and what they need most.
A united patient voice matters. It helps us advocate to government and industry for better awareness, better care and better treatment access. Every person who joins makes that voice stronger, and it costs you nothing but a few minutes.
Joining is free, confidential and open to patients, families and carers across Australia.

Treatment access advocacy
Historically, options for people with hypoparathyroidism have been limited, and standard management is usually built around calcium and active vitamin D supplements prescribed and monitored by your doctor. Treatment is always tailored to the individual, so never change your medication without speaking to your clinician.
There is real reason for hope. New treatments for CaSR disorders are in late-stage clinical trials. CaSR Patient Support advocates for Australians to have timely, equitable access to new treatments as they progress, and for the patient voice to be heard by regulators and decision-makers.
By joining our community, you help build the collective patient voice that makes this advocacy possible.

Frequently asked questions
What is hypoparathyroidism?
Hypoparathyroidism is a rare condition where the body does not make enough parathyroid hormone (PTH), the hormone that helps keep blood calcium at the right level. As a result, calcium levels can fall too low. It is usually a long-term condition that is managed with the help of an endocrinologist.
What are the common symptoms of hypoparathyroidism?
Because calcium is important for nerves and muscles, low calcium can cause tingling or numbness (often in the fingers or around the mouth), muscle cramps or spasms, fatigue, and difficulty concentrating, which is sometimes called brain fog. Symptoms vary from person to person and can change from day to day. Always discuss your symptoms with your doctor.
Is hypoparathyroidism genetic?
It can be. Some people develop hypoparathyroidism after surgery, while others have a non-surgical or genetic form. One genetic cause is a change in the calcium-sensing receptor (CaSR) gene, which leads to a condition called ADH1 (autosomal dominant hypocalcaemia type 1). Genetic testing, arranged by your specialist, can help identify the cause.
How is hypoparathyroidism treated?
Most people manage hypoparathyroidism with calcium and active vitamin D supplements prescribed by their doctor, along with regular blood tests to keep calcium in a safe range. Treatment is tailored to each person, so never change your medication without speaking to your clinician. New treatments for CaSR disorders are in late-stage clinical trials.
Can I live a normal life with hypoparathyroidism?
Many people with hypoparathyroidism live full lives with the right support and monitoring. Because the condition is long-term and can be unpredictable, connecting with others who understand, and having reliable information, makes a real difference. CaSR Patient Support is here to help you feel less alone.
Is there support for hypoparathyroidism in Australia?
Yes. CaSR Patient Support is an Australian charity for people living with hypoparathyroidism, calcium-sensing receptor disorders and ADH1. We offer free peer support, a national patient community, trusted information and advocacy for better treatment access. You can join for free at https://casr.org.au/join/.
How do I connect with other people living with hypoparathyroidism?
Joining the CaSR Patient Support community is free and takes only a few minutes. When you join, you connect with other Australians who understand what you are going through, receive trusted updates, and add your voice to advocacy for better treatment access. Sign up at https://casr.org.au/join/.
