The Challenging Management of Rheumatoid Arthritis Overlapping With Graves' Disease in a Young Male: A Case Report.

Autoimmune disorders occur when the body's immune system mistakenly attacks its own tissues. Generally, these disorders are more prevalent in female patients. The presence of one autoimmune disease can alter the immune system's balance, making the individual more susceptible to developing other autoimmune conditions. Rheumatoid arthritis and Graves' disease are two examples of autoimmune conditions that can overlap in the same patient. In this case report, we present a unique scenario of a male patient initially exhibiting symptoms suggestive of gravis' disease. The subsequent emergence of signs and symptoms of rheumatoid arthritis further complicated the situation. This overlapping presentation posed significant challenges in managing his condition and balancing the treatment regimens for both conditions while minimizing potential drug interactions and adverse effects.
