Inclusion Body Myositis (IBM) is a rare inflammatory muscle disease that primarily affects older adults. It leads to progressive muscle weakness and wasting, particularly in the arms and legs. Symptoms often develop slowly and may include difficulty climbing stairs, lifting objects, or gripping items. The exact cause of IBM is not fully understood, but it is believed to involve an autoimmune response where the body's immune system mistakenly attacks muscle fibers. Diagnosis typically involves blood tests, muscle biopsies, and imaging studies to assess muscle damage and inflammation. Treatment options are limited and focus on managing symptoms and improving quality of life.
