Study Notes
Respiratory Diseases
Definition
Respiratory diseases affect the lungs and other parts of the respiratory system, making it difficult to breathe and get oxygen to the body.
Types of Respiratory Diseases
- Chronic Obstructive Pulmonary Disease (COPD): a progressive lung disease that makes it hard to breathe, including emphysema and chronic bronchitis
- Asthma: a condition that causes recurring episodes of wheezing, coughing, chest tightness, and shortness of breath
- Pneumonia: an infection that inflames the air sacs in the lungs, filling them with fluid
- Lung Cancer: a type of cancer that affects the lungs, often caused by smoking
- Cystic Fibrosis: a genetic disorder that affects the respiratory, digestive, and reproductive systems
Causes and Risk Factors
- Smoking and secondhand smoke
- Air pollution
- Genetic predisposition
- Infections
- Allergies
- Occupation-related exposures (e.g., asbestos)
Symptoms
- Shortness of breath
- Wheezing
- Coughing
- Chest tightness
- Fatigue
- Blue-tinged lips or fingers (in severe cases)
Treatment and Prevention
- Quitting smoking and avoiding secondhand smoke
- Vaccinations (e.g., flu, pneumonia)
- Medications (e.g., bronchodilators, corticosteroids)
- Lifestyle changes (e.g., exercise, healthy diet)
- Avoiding triggers (e.g., allergens, pollution)
Infectious Diseases
Definition
Infectious diseases are caused by pathogens (e.g., bacteria, viruses, fungi) that enter the body and cause harm.
Types of Infectious Diseases
- Bacterial Infections: caused by bacteria, such as tuberculosis, salmonella, and E. coli
- Viral Infections: caused by viruses, such as influenza, HIV, and herpes
- Fungal Infections: caused by fungi, such as ringworm and athlete's foot
- Parasitic Infections: caused by parasites, such as malaria and tapeworms
Causes and Risk Factors
- Poor hygiene
- Contaminated food and water
- Inadequate vaccination
- Weakened immune system
- Close contact with infected individuals
- International travel
Symptoms
- Fever
- Fatigue
- Pain or discomfort
- Swelling or inflammation
- Nausea and vomiting
- Diarrhea or abdominal cramps
Treatment and Prevention
- Vaccinations
- Antibiotics (for bacterial infections)
- Antiviral medications (for viral infections)
- Antifungal medications (for fungal infections)
- Personal protective equipment (e.g., masks, gloves)
- Improved hygiene practices (e.g., handwashing, proper food handling)
Sexually Transmitted Diseases (STDs)
Definition
STDs are infections spread through sexual contact, including vaginal, anal, and oral sex.
Types of STDs
- Bacterial STDs: caused by bacteria, such as chlamydia, gonorrhea, and syphilis
- Viral STDs: caused by viruses, such as herpes, HIV, and human papillomavirus (HPV)
- Parasitic STDs: caused by parasites, such as pubic lice and scabies
Causes and Risk Factors
- Unprotected sex
- Multiple sexual partners
- Sharing needles or injecting equipment
- Poor sexual hygiene
- Lack of knowledge about STDs
Symptoms
- Unusual discharge or odor
- Pain or burning during urination
- Itching or redness in the genital area
- Sores or lesions on the genitals
- Swollen lymph nodes
Treatment and Prevention
- Antibiotics (for bacterial STDs)
- Antiviral medications (for viral STDs)
- Condoms and other barrier methods
- Vaccinations (e.g., HPV vaccine)
- Regular STD testing
- Abstinence or monogamy
