Understanding Non-Infectious Diseases and Transplants

Non-Infectious Diseases

Non-infectious diseases are conditions that are not caused by infectious agents. They are often chronic and require long-term care.

Cancer

Cancer is a disease that occurs when cells in a body tissue undergo transformation, reproducing abnormally and uncontrollably. It is the second leading cause of unnatural death after cardiovascular diseases.

Major cancers include lung, colon, skin (epithelial), and pancreatic cancer.

Cancer Causes

• Genetic factors
• Chemical exposure
• Physical factors (e.g., ionizing radiation)
• Viruses
• Environmental factors
• Diet

Cancer Prevention

• Maintain a healthy diet
• Avoid tobacco use
• Engage in regular physical exercise
• Avoid excessive exposure to the sun
• Comply with legislation on carcinogens in the workplace

Cardiovascular Disease

Cardiovascular diseases are conditions that affect the heart and blood vessels. They are the leading cause of death in Western societies. They may have a genetic origin, but the most well-known cardiovascular risk factors are inadequate diet, lack of physical activity, and tobacco use.

Cardiovascular Disease Prevention

Individual Prevention Measures

• Maintain a healthy diet
• Reduce salt consumption
• Control hypertension (high blood pressure)
• Engage in regular moderate exercise
• Avoid protracted anxiety and stress
• Prevent or moderate alcohol consumption

Collective Prevention Measures

Policy measures recommended by organizations like the WHO:

• Raising taxes on alcohol and tobacco
• Creating infrastructure for pedestrians and bicycles
• Inspecting school canteens and food companies

Mental Illness

Mental illnesses are chemical disorders in the brain that affect how people think, feel, and relate to others. They can often be treated medically.

Types of Mental Illness

• Depression
• Schizophrenia
• Anxiety disorders
• Bipolar disorder
• Alzheimer's disease
• Parkinson's disease

Transplantation

The Transplantation Process

Transplantation is surgery that replaces diseased tissues or organs with those from another person. The main problem is preventing rejection. Before transplantation, checks ensure donor and recipient compatibility. After surgery, the recipient receives specific chemical substances to help prevent rejection.

Organ and Tissue Transplantation

The increasing demand for organ transplants is a worldwide call for solidarity among people: donors, recipients, and families.

Important transplanted organs and tissues include:

• Kidney
• Liver
• Heart
• Lung
• Intestine
• Bones
• Heart valves
• Corneas
• Skin

Global Health Challenges

Health Problems in Developing Nations

Significant health challenges in the developing world include:

• Public health issues
• Lack of medical staff capacity
• Insufficient clinics and hospitals
• Inadequate medical benefits
