Immune System Dysfunction Diseases

• Autoimmune diseases occur when the immune system mistakenly attacks the body's own tissues, examples include lupus and rheumatoid arthritis.
• Immunodeficiency diseases result from impaired immune responses, leading to increased susceptibility to infections, such as HIV/AIDS.
• Allergies arise from an overactive immune response to harmless substances, resulting in symptoms like asthma or eczema.

• Diseases can range from infectious pathogens to genetic disorders and chronic conditions affecting various systems.

Possible Causes of Diseases

• Genetic mutations can lead to hereditary diseases, influencing a range of conditions from cancers to cystic fibrosis.
• Environmental factors, such as pollution or radiation, can trigger diseases by damaging cells or altering physiological processes.
• Lifestyle choices, including diet and exercise, significantly impact health and can lead to diseases like diabetes and cardiovascular conditions.

Common Outcomes of Diseases

• Diseases often result in pain, discomfort, or limitations in daily activities, affecting quality of life.
• Chronic diseases may lead to permanent damage to organs and systems, causing long-term health complications.

Adverse Effects on Organisms

• Diseases can disrupt homeostasis, leading to significant physiological imbalances that jeopardize health.
• Immunological diseases can impair the organism's ability to defend against infections, increasing vulnerability to further health issues.
