Markus J. Seibel is a Rheumatologist based at Gate 3, Hospital Road, Concord, NSW 2139, Australia.
Rheumatology looks after long-term problems that involve joints, bones, and the tissues around them. In day-to-day care, that can mean help with arthritis symptoms, ongoing stiffness, and pain that keeps coming back. Markus also looks at bone health issues, especially when they are linked to things like hormone changes, bone strength, or unusual bone growth.
Some people see him for conditions like rheumatoid arthritis (RA) and osteoarthritis. These can affect the way someone moves, sleep, and even how they manage basic tasks. Others come with bone-related problems such as osteoporosis, postmenopausal osteoporosis, Paget’s disease of bone, osteomalacia, and rickets. At times, there are also concerns like osteolysis and bone tumours, which can need careful assessment and ongoing follow-up.
There are also broader health issues that can show up in the bones and muscles. Markus works with people dealing with chronic pain, muscle atrophy, and malnutrition. Metabolic problems can play a role too, such as metabolic syndrome and obesity. In some cases, hormone-related conditions like Cushing’s disease or Cushing’s syndrome are part of the picture, along with issues like hypophosphatemia and x-linked hypophosphatemia.
Care isn’t just about one test or one scan. Over time, it’s about getting the story right, spotting what’s driving the symptoms, and making a plan that fits what’s going on for that person. Markus also treats people with conditions that can affect the body more widely, including systemic mastocytosis and thyroid-related problems like thyrotoxic periodic paralysis.
He works with patients who want clear explanations and a practical approach. Appointments are used to understand symptoms, review how things are changing, and talk through the next steps. The goal is to help people feel steadier and more confident managing their condition, whether the issue is mainly in the joints, mainly in bone health, or a mix of both.
