Richard S. Loh is an Allergist / Immunologist based in Sydney, NSW, Australia. He looks after people with allergy and immune system problems, from day-to-day symptoms to more serious reactions.
In clinic, the focus is often on conditions like anaphylaxis and food allergy. These are tough, because they can affect everyday life and can feel scary when symptoms flare up. He also helps manage asthma, especially where allergies and triggers seem to play a part.
For many people, skin problems are part of the story too. Richard works with patients who have atopic dermatitis (eczema), and he spends time thinking through what might be setting off irritation and itch in the first place. At times, it’s not just one thing. It can be seasons, stress, skin care routines, and other triggers all mixing together.
Allergic reactions can show up in different ways. Grass allergy is a common example, and it can hit hard during certain times of the year. Managing it well usually means working out the patterns, spotting likely triggers, and putting a practical plan in place for when symptoms start.
Richard also works with immune-related conditions such as Common Variable Immune Deficiency. This isn’t something people hear about every day, and it can bring ongoing health worries. In cases like this, care is about staying on top of infections and supporting the immune system in a steady, sensible way.
At times, the immune system can be involved in rarer complications too. His work includes complex situations where issues like coronary artery aneurysm may be part of the bigger medical picture. When that happens, he works alongside other clinicians so decisions are coordinated and clear.
Over time, his experience has centred on allergy and immunology care, helping people understand what’s driving their symptoms and what options may help. He aims for a calm, down-to-earth approach, because the goal is usually the same: fewer flare-ups, better day-to-day control, and a plan that fits real life.
