What is sarcoidosis?

Sarcoidosis happens when inflammation causes small clusters of immune cells, called granulomas, to form in the body. These granulomas can appear in different organs and may interfere with how those organs work.

Because sarcoidosis can affect people differently, no two experiences are the same.

• Lungs & Breathing — Shortness of breath, cough, chest discomfort, and lung inflammation.
• Lymph Nodes — Swollen lymph nodes in the neck, chest, or other areas.
• Skin — Rashes, nodules, lupus pernio, and other skin changes.
• Eyes — Dry eyes, irritation, inflammation, and vision-related changes.
• Heart & Nervous System — In some cases, sarcoidosis may affect the heart or nervous system.
• Whole-Body Impact — Fatigue, pain, inflammation, and symptoms that can affect daily life.

• fatigue
• shortness of breath
• persistent cough
• chest discomfort
• swollen lymph nodes
• joint pain
• skin changes
• eye irritation or vision changes
• fever or night sweats
• unexplained weight changes
• general pain or weakness

Symptoms vary from person to person. This list is for general awareness only and should not be used to self-diagnose.

Doctors may use medical history, physical exams, imaging, blood tests, lung function tests, biopsies, or specialist evaluations to better understand what is happening.

Treatment depends on the person, the organs involved, and the severity of the disease. Some cases may be monitored over time, while others may require medication or ongoing specialist care.
