Signs and symptoms of amyloidosis overview

Amyloidosis occurs when amyloid proteins collect in tissues and organs, causing them to function less effectively. These deposits may develop over time and can affect different areas of the body, including the heart, kidneys, liver, and nervous system. As amyloid builds up, people may experience symptoms such as fatigue, swelling, shortness of breath, and unexplained weight loss. Since these symptoms can resemble those of other conditions, recognizing them can be challenging. Early awareness of possible signs encourages people to seek medical advice, as doctors need specific tests to confirm the presence of amyloidosis and determine the best course of treatment.

Common Signs and Symptoms of Amyloidosis

Since amyloidosis can affect multiple organ systems, its symptoms vary depending on which parts of the body are involved. Some of the most frequently observed signs include fatigue, weakness, and swelling. These symptoms often develop gradually, making early detection challenging.

Cardiac Symptoms

When amyloid proteins deposit in the heart, they can cause restrictive cardiomyopathy. This may lead to symptoms such as shortness of breath, especially during exertion or when lying down, and swelling in the legs or ankles. Patients might also experience irregular heartbeats or a sensation of fullness in the chest.

Renal Symptoms

Amyloid deposits in the kidneys can impair their ability to filter waste, resulting in proteinuria—excess protein in the urine—which may be detected through laboratory tests. Swelling in the legs, ankles, or face can also occur due to fluid retention caused by kidney dysfunction.

Gastrointestinal Symptoms

Involvement of the gastrointestinal tract can lead to symptoms such as difficulty swallowing, nausea, diarrhea, or constipation. Some individuals may notice unintentional weight loss or a feeling of fullness after eating small amounts of food.

Neurological Manifestations

Nerve involvement may produce sensations of numbness, tingling, or weakness, especially in the extremities. Autonomic nerve damage can cause symptoms like dizziness upon standing, abnormal sweating, or gastrointestinal motility issues.

Other Possible Signs

Skin changes, such as purplish or waxy patches, can sometimes appear in areas where amyloid deposits are present. Additionally, enlarged organs like the liver or spleen are detectable during physical examinations or imaging studies. Unexplained weight loss and general malaise are also common.
