Usually if this initial work-up is consistent with the presentation of amyloidosis, a biopsy of the suspected organ involved is used for diagnosis, such as an abdominal fat biopsy, kidney biopsy, or a heart biopsy.<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p><strong>Treatment<\/strong><\/p>\n<p>Close medical follow-up is usually offered, with support from your healthcare team. If indicated, your doctor may recommend specialists for you to follow-up with as well.<\/p>\n<p>The treatment options can vary greatly based on the type and location of amyloid. There are several oral medications used to reduce or stabilize the amyloid deposition in your body or decrease the amount of amyloid that is produced by your body. Medications, often used in other conditions like rheumatoid arthritis, can also help the side-effects experienced with amyloid.\u00a0 In some types, chemotherapy or stem cell transplant may be used. Your doctor may also think that in cases of severe organ damage, an organ transplant such as a liver or heart transplant is indicated.<\/p>\n<p>Genetic testing in amyloidosis is a personal and complex decision, with emotional and social aspects to consider; however, it can also inform treatment.<\/p>\n<p>&nbsp;<\/p>\n<p><img src=\"https:\/\/encrypted-tbn0.gstatic.com\/images?q=tbn:ANd9GcTPEocU7peez8NNgWTex66XBLTN5TSJVTwcEQ&amp;usqp=CAU\" alt=\"CODE OF CONDUCT\" \/><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p style=\"text-align: center;\"><strong>Please consider the following resources to learn more<\/strong><\/p>\n<p>Amyloid Research Consortium CEO discusses her experiences as a patient, and the signs and symptoms of amyloidosis in the following video :<\/p>\n<div class=\"responsiveVideo responsive-youtube\"><iframe loading=\"lazy\" title=\"The Balancing Act with ARC CEO Isabelle Lousada\" width=\"500\" height=\"281\" src=\"https:\/\/www.youtube.com\/embed\/bWf-NVA3aiQ?start=100&#038;feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n<p><a href=\"http:\/\/amyloidosis.org\/wp-content\/uploads\/2020\/03\/2018-ATTR-guide.pdf\">An ATTR amyloidosis brochure created by the Amyloidosis foundation<\/a><\/p>\n<p><a href=\"http:\/\/amyloidosis.org\/wp-content\/uploads\/2020\/03\/2020-patient-overview.pdf\">An amyloidosis brochure created by the Amyloidosis Foundation<\/a><\/p>\n<p>&#8220;Amyloidosis: The Basics&#8221; created by the Amyloidosis Foundation<\/p>\n<div class=\"responsiveVideo responsive-youtube\"><iframe loading=\"lazy\" title=\"Amyloidosis Informational Video\" width=\"500\" height=\"375\" src=\"https:\/\/www.youtube.com\/embed\/Mxj2yUDg2dE?feature=oembed\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture\" allowfullscreen><\/iframe><\/div>\n","protected":false},"excerpt":{"rendered":"<p>What is amyloidosis?
