Summary
Amyloidosis is a condition where abnormal proteins, called amyloids, build up in organs and tissues. This buildup can interfere with normal function, leading to organ damage. The disease progresses as more amyloid deposits accumulate, affecting organs like the heart, kidneys, and liver.
Amyloidosis occurs when proteins misfold and form amyloid deposits in organs. Genetic factors, chronic infections, or inflammatory diseases can increase risk. Some types are hereditary, while others are linked to conditions like multiple myeloma, which is a type of blood cancer.
Common symptoms include fatigue, swelling, and weight loss. Complications arise as amyloid deposits disrupt organ function, leading to heart failure, kidney damage, and nerve issues. These complications significantly affect health and quality of life.
Amyloidosis is diagnosed through symptoms and tests. A biopsy, which involves taking a small tissue sample, confirms amyloid deposits. Blood and urine tests detect abnormal proteins. Imaging tests like echocardiograms assess organ involvement.
Preventing amyloidosis involves managing underlying conditions like chronic infections. Treatments include chemotherapy and medications to manage symptoms and slow progression. Early diagnosis and treatment are crucial for better outcomes.
Self-care includes a balanced diet, staying active with low-impact exercises, and avoiding smoking. Regular medical check-ups and adhering to treatment plans are crucial. These actions help maintain organ function and improve quality of life.
