Simon J. Clarke is an Endocrinologist based in Sydney, NSW, Australia. He works with people who have hormone-related health issues, where the body’s signals can be off in small but important ways.
In day to day practice, he sees patients dealing with problems linked to the pituitary and other hormone systems. This can include things like hypopituitarism, Sheehan syndrome, and hypophosphatemia. At times, hormone imbalance can also show up as low sodium levels, which can feel scary and confusing for patients and families.
Simon also helps people where growth and metabolism are affected. For example, he may be involved in care around gigantism. These conditions can have long timelines and can be tricky to manage without careful, steady follow up.
His work isn’t limited to hormone levels alone. He also looks after patients with nutrition and blood-related problems, such as malnutrition and vitamin B12 deficiency anaemia. When someone’s diet, weight, or blood counts are struggling, the root cause isn’t always just “food choices”, and hormone issues can play a role in some cases.
Some referrals come from people who have complex health needs alongside other conditions. For instance, attention deficit hyperactivity disorder (ADHD) may be part of a wider health picture where hormones and nutrition are worth checking. There are also situations involving subacute combined degeneration, where symptoms can overlap with vitamin and nerve health concerns.
Because hormone conditions can be lifelong, good care often comes down to practical steps and clear explanations. Over time, Simon focuses on making a plan that fits the person’s situation, then adjusting it as test results and symptoms change. Many patients find it helps to have someone who listens and takes the time to work through what the results might mean.
He stays across current research and guidelines so decisions are based on the latest evidence. If clinical trial options are relevant for a specific case, those can be discussed as part of care planning, but not every situation will need that kind of approach.
Simon J. Clarke is a Sydney endocrinologist who looks after patients with a mix of hormone, growth, nutrition, and related health concerns, including conditions like anorexia and low sodium levels. The goal is simple: keep care steady, make things understandable, and support people through treatment when their body’s systems aren’t quite working as they should.
