Lists of diseases

Human diseases and disorders refer to the wide range of medical conditions that can affect the health and well-being of individuals. They can be caused by various factors, including genetic predisposition, environmental factors, lifestyle choices, infections, and psychological conditions.

Classification

Diseases and disorders can be classified in several ways, including by cause, by symptoms, or by the organ system affected.

By Cause

• Infectious diseases - Caused by pathogenic microorganisms, such as bacteria, viruses, parasites, or fungi.
• Genetic disorders - Caused by abnormalities in an individual's DNA.
• Lifestyle diseases - Associated with the way a person or group of people live, such as heart disease and diabetes mellitus.
• Environmental diseases - Resulting from exposure to environmental toxins or allergens.

By Symptoms or Signs

• Autoimmune diseases - Where the immune system attacks healthy cells in the body by mistake.
• Cancer - Characterized by the uncontrolled growth and spread of abnormal cells.
• Chronic diseases - Long-lasting conditions that can be controlled but not cured.

By Organ or System Affected

• Cardiovascular diseases - Affecting the heart or blood vessels.
• Neurological disorders - Affecting the nervous system.
• Respiratory diseases - Impacting the lungs and the ability to breathe.
• Digestive diseases - Affecting the gastrointestinal tract.

Prevention and Treatment

Prevention and treatment measures vary widely depending on the specific disease or disorder, ranging from vaccines and lifestyle modifications to pharmaceutical interventions and surgery.

Prevention

• Vaccination - For preventable infectious diseases.
• Healthy lifestyle - Including proper diet, exercise, and avoidance of tobacco and excessive alcohol consumption.
• Public health - Measures to control the spread of diseases, such as sanitation and food safety standards.

Treatment

• Medication - Pharmaceutical drugs to treat or manage symptoms.
• Surgery - Invasive procedures to remove or repair damaged tissues or organs.
• Psychotherapy - For mental health disorders.
• Physical therapy - To rehabilitate after injuries or surgeries and to manage chronic conditions.

Epidemiology

The study of the patterns, causes, and effects of health and disease conditions in defined populations is known as epidemiology. It is the cornerstone of public health and shapes policy decisions by identifying risk factors for disease and targets for preventive healthcare.

Challenges

The global burden of disease is a critical concern, with challenges including emerging infectious diseases, antibiotic resistance, and the increase in chronic diseases due to aging populations.
