Amyloidosis is a disease characterized by abnormal deposits of a protein called amyloid in tissues and organs throughout the body. These deposits can impact the functioning of the affected organs, leading to a wide variety of health issues. The disease can affect different organs such as the heart, kidneys, liver, spleen, nervous system, and digestive tract.

The condition can be either systemic or localized. Systemic amyloidosis affects the entire body, whereas localized amyloidosis affects a single area. It is a rare disease, but it can be serious and even life-threatening if not diagnosed and treated appropriately.
