Rheumatoid Arthritis – Rheumatoid arthritis is a chronic inflammatory disorder that primarily affects the joints. It typically causes swelling, pain, and stiffness, often in the hands and feet. Over time, it can lead to joint damage and deformities. The disease progresses through periods of flares and remissions. It can also affect other parts of the body, including the skin, eyes, and lungs. The exact cause is unknown, but it involves the immune system attacking the body’s own tissues.
Systemic Lupus Erythematosus – Systemic lupus erythematosus is an autoimmune disease where the immune system attacks healthy tissues. It can affect the skin, joints, kidneys, brain, and other organs. Symptoms vary widely but often include fatigue, joint pain, and skin rashes. The disease can progress with periods of increased activity, known as flares, and times of remission. The exact cause is not fully understood, but it involves genetic and environmental factors. It is more common in women than men.
Sarcoidosis – Sarcoidosis is an inflammatory disease characterized by the formation of small clumps of inflammatory cells, called granulomas, in various organs. It most commonly affects the lungs and lymph nodes but can involve any organ. Symptoms can include cough, shortness of breath, and fatigue. The progression of sarcoidosis varies; it can resolve on its own or become chronic. The cause of sarcoidosis is unknown, but it is thought to involve an abnormal immune response. It can affect people of any age, but it is more common in adults.
Idiopathic Pulmonary Fibrosis – Idiopathic pulmonary fibrosis is a chronic lung disease that results in scarring of the lung tissue. This scarring makes it difficult for the lungs to work properly, leading to symptoms like shortness of breath and a persistent dry cough. The disease progresses over time, with lung function gradually declining. The cause of idiopathic pulmonary fibrosis is unknown, but it is believed to involve genetic and environmental factors. It primarily affects older adults. The progression rate can vary significantly among individuals.
Scleroderma – Scleroderma is a group of autoimmune diseases that cause hardening and tightening of the skin and connective tissues. It can affect only the skin or involve internal organs, such as the heart, lungs, and kidneys. Symptoms include skin thickening, joint pain, and digestive issues. The disease progresses differently in each person, with some experiencing mild symptoms and others having severe complications. The exact cause is unknown, but it involves the immune system attacking the body’s own tissues. It is more common in women than men.
