Skin Infections: Types, Symptoms and Treatment
Learn how bacterial, fungal and viral infections affect the skin and how to care for your skin safely.
What are skin infections?
Skin infections occur when microorganisms such as bacteria, fungi or viruses affect the skin. Some parasitic infestations, such as scabies, can also cause intense itching and skin irritation. The appearance and severity depend on the cause and the part of the body affected.
Common types
- Fungal infections: Ring-shaped, scaly or itchy patches; athlete's foot may affect the spaces between the toes.
- Bacterial infections: May cause redness, warmth, swelling, tenderness or pus.
- Viral infections: Some cause blisters, warts or painful skin eruptions.
- Parasitic infestations: Scabies may cause intense itching, particularly at night.
Causes and risk factors
Heat, sweating, skin-to-skin contact, shared personal items, minor skin injuries and weakened skin barriers can contribute to certain infections. Risk factors differ according to the organism.
Prevention and treatment
Keep skin clean and dry, avoid sharing towels and seek medical advice for persistent rashes. Treatment may involve an appropriate antifungal, antibiotic or other medicine, depending on the diagnosis. Avoid using steroid combination creams without medical guidance.
When to consult a doctor
Seek assessment for spreading redness, persistent lesions, recurring infections or a rash that does not improve. Fever, severe pain or rapidly spreading swelling requires prompt medical attention.
Hair Fall: Causes, Diagnosis and Treatment
Understand common reasons for hair shedding, thinning hair and available treatment approaches.
What is hair fall?
Hair naturally sheds as part of its growth cycle. When shedding becomes excessive or hair density decreases, it may indicate a condition that needs evaluation. Hair loss can be temporary, progressive or associated with scalp disease.
Common causes
- Illness, major stress or surgery followed by temporary shedding.
- Iron deficiency, inadequate nutrition or certain medical conditions.
- Hereditary pattern hair loss and hormonal influences.
- Thyroid disorders, scalp inflammation or certain medicines.
- Tight hairstyles and repeated chemical or heat damage.
Symptoms to notice
Hair may thin gradually, shed more during washing, form patches or break easily. Scalp itching, scaling, pain or scarring may suggest a separate scalp condition.
Diagnosis and treatment
A dermatologist may examine the scalp, review family history and recent health changes, and request blood tests when appropriate. Treatment depends on the cause and may include targeted medicines, correcting nutritional deficiencies, treating scalp disease or suitable hair-loss therapies. PRP or other procedures may be considered for selected patients after assessment.
Hair care and prevention
Eat a balanced diet with adequate protein, avoid tight hairstyles and reduce excessive heat styling. Do not take high-dose supplements without confirming whether they are needed.
When to consult a doctor
Arrange an assessment for sudden, patchy or persistent hair loss, scalp pain or visible scarring. Early diagnosis can help protect hair follicles in some conditions.
Nail Infections: Signs and Treatment Options
Discover why nails may become thick, brittle, discolored or painful.
What are nail infections?
Nail infections affect the nail plate, the skin surrounding the nail or the tissue beneath it. Fungal infections are common, but not every nail discoloration or thickened nail is caused by fungus.
Common signs
- Yellow, white or brown discoloration.
- Thickened, brittle or crumbly nails.
- Separation of the nail from the nail bed.
- Redness, swelling or pain around the nail.
Causes and risk factors
Moist environments, repeated nail trauma, shared nail equipment and certain medical conditions can increase risk. Nail biting and frequent exposure to water may also damage the surrounding skin.
Diagnosis and treatment
A clinician may examine the nail and collect a sample before prescribing antifungal treatment. Depending on the infection, treatment may be topical or oral. Oral antifungals require medical assessment because of possible side effects and drug interactions.
Prevention
Keep nails clean and dry, wear footwear in communal wet areas, avoid sharing nail tools and have manicure equipment properly sterilized. Do not cover a painful or infected nail with artificial nails without assessment.
When to seek care
Consult a dermatologist for persistent discoloration, nail separation or recurring infections. Increasing redness, pus, fever or severe pain requires prompt assessment.
Laser Tattoo Removal: Procedure and Aftercare
Understand how laser treatment breaks down tattoo pigment and what to expect.
How does tattoo removal work?
Professional laser tattoo removal uses selected wavelengths of light to target tattoo pigment. The body's immune system gradually clears fragmented pigment. Several treatment sessions are commonly needed, with recovery time between sessions.
What affects the results?
- Ink color, depth and quantity.
- Age, size and location of the tattoo.
- Skin type and the laser technology used.
- Individual healing and immune response.
What happens during treatment?
The skin is assessed first and protective eyewear is used. Treatment may feel like repeated snapping sensations. A temporary whitening effect, redness or swelling may occur immediately afterward.
Risks and aftercare
Possible risks include blistering, infection, scarring and lighter or darker patches of skin. Follow the clinician's wound-care instructions, avoid picking blisters and protect the area from sunlight during healing.
Is complete removal guaranteed?
No. Some tattoos fade considerably, while others leave residual pigment or a shadow. Cosmetic tattoos may change color during treatment, so careful assessment is important.
Who should perform it?
Consult a qualified dermatologist or appropriately trained medical professional working within their scope. A personal assessment helps determine suitability, expected results and risks.
Laser Hair Removal: Benefits and Skin Care
Learn about long-term hair reduction, treatment sessions and safe aftercare.
What is laser hair removal?
Laser hair removal uses concentrated light absorbed by pigment in hair follicles. It can reduce unwanted hair growth over time. It is often called laser hair reduction because complete permanent removal cannot be guaranteed.
Which areas can be treated?
Common treatment areas include the face, upper lip, chin, underarms, arms, legs, back and bikini area, depending on individual suitability.
How many sessions are needed?
Hair grows in different phases, so multiple sessions spaced several weeks apart are generally required. Maintenance sessions may be needed. Results vary with hair color, skin type, hormonal factors and the treatment device.
Benefits and possible risks
Potential benefits include longer-lasting hair reduction and fewer ingrown hairs for some people. Temporary redness and swelling can occur. Burns, scarring and pigmentation changes are possible if the procedure is unsuitable or incorrectly performed.
Before and after treatment
Follow the clinic's shaving and preparation instructions. Avoid tanning and disclose medicines or skin conditions. After treatment, use gentle skin care and sun protection as advised. Avoid waxing or plucking between sessions if instructed, because these remove the targeted hair.
Who needs extra assessment?
People with recent tanning, active skin infections or medicines that increase light sensitivity should discuss these factors with their clinician before treatment. A qualified provider should select the device and settings for the individual's skin and hair.
Acne and Pimples: Causes and Treatment
Learn why acne develops and how consistent skin care can help manage breakouts.
What is acne?
Acne is a common skin condition that develops when hair follicles become blocked with oil and dead skin cells. It may cause blackheads, whiteheads, inflamed pimples, deeper lumps and, in some cases, permanent scars.
Why does acne develop?
- Increased oil production and blocked pores.
- Hormonal changes, particularly during adolescence.
- Inflammation and changes in bacteria within follicles.
- Some medicines, cosmetics and individual lifestyle factors.
Common acne myths
Acne is not simply caused by dirty skin. Scrubbing aggressively can irritate it, and squeezing pimples may increase inflammation and scarring. Diet can influence acne in some people, but triggers vary.
Skin care tips
Wash gently twice daily, choose non-comedogenic products and avoid picking lesions. Use sunscreen suitable for your skin. Introduce acne products gradually to reduce irritation.
Treatment options
Depending on severity, treatment may include topical retinoids, benzoyl peroxide, other topical medicines, oral medicines or selected procedures. Some treatments are unsuitable during pregnancy. A dermatologist can select an appropriate plan and help prevent scars.
When to consult a dermatologist
Seek care for painful nodules, persistent acne, scarring or acne affecting confidence and daily life. Early treatment can reduce the risk of lasting scars.
Dark Spots and Pigmentation: Causes and Care
Understand melasma, sun-related spots and pigmentation left after inflammation.
What is skin pigmentation?
Pigmentation refers to areas of skin that appear darker than the surrounding skin. It can result from increased melanin, the pigment responsible for skin color. The pattern and cause help determine suitable treatment.
Common causes
- Sun exposure and visible light contributing to certain pigment conditions.
- Melasma, which can be associated with hormonal changes.
- Dark marks left after acne, eczema or skin injury.
- Irritation caused by unsuitable cosmetic products.
Prevention and daily care
Use broad-spectrum sunscreen and reapply as directed, particularly outdoors. A hat and shade can provide additional protection. Avoid harsh scrubs, unregulated skin-lightening creams and products that cause burning or irritation.
Treatment options
Depending on the diagnosis, a dermatologist may recommend topical treatments, chemical peels or selected laser procedures. Results often take time, and pigmentation may return if triggers persist. Some products require special precautions during pregnancy.
When to seek assessment
Consult a dermatologist for persistent or unexplained dark patches. A new spot that changes in size, shape or color, or bleeds, should be medically assessed rather than treated as routine pigmentation.
Warts and Skin Tags: Differences and Removal
Understand these common skin growths and why correct identification matters.
What are warts?
Common warts are usually caused by human papillomavirus (HPV) affecting the skin. They may appear as rough, raised growths on the hands, feet or other areas. Some can spread through direct contact.
What are skin tags?
Skin tags are usually soft, benign growths that often develop around the neck, underarms, groin or eyelids. Friction may contribute to their development. They are different from viral warts.
How are they diagnosed?
A dermatologist examines the growth and may recommend further testing if it looks unusual. Not every raised or pigmented growth is a wart or skin tag.
Removal options
Depending on the diagnosis and location, treatment may include freezing, carefully selected cautery, surgical removal or other procedures. Warts may require more than one session and can recur.
Safety and aftercare
Do not cut, burn or tie off growths at home, especially around the eyes or genitals. Home removal may cause bleeding, infection, burns or scars. Follow wound-care advice after professional removal.
When to seek medical advice
Have a growth assessed if it grows rapidly, changes color, bleeds, becomes painful or repeatedly returns. A correct diagnosis is essential before removal.
Chemical Peels: Benefits, Procedure and Aftercare
Explore how professionally selected chemical peels may improve certain skin concerns.
What is a chemical peel?
A chemical peel uses a selected chemical solution to exfoliate controlled layers of skin. Depending on the type and depth, it may help improve acne, uneven tone, selected pigmentation and skin texture.
Types of chemical peels
- Superficial peels: Target the outermost layers of skin.
- Medium-depth peels: Reach deeper layers and generally require more recovery.
- Deep peels: Have greater risks and are suitable only for selected cases under appropriate specialist care.
What happens during treatment?
The clinician assesses the skin, medical history, medicines and the condition being treated. Mild tingling or temporary redness may occur. The product and treatment duration should be selected according to the patient's skin and goals.
Aftercare
Use gentle cleansing, moisturizer and broad-spectrum sunscreen. Do not peel or pick flaking skin. Avoid irritating active ingredients until your clinician advises that they can be restarted.
Possible side effects
Redness, dryness, peeling and temporary sensitivity are possible. Burns, infection, scarring and persistent pigmentation changes can occur, particularly with inappropriate treatment or aftercare.
Who should consult a dermatologist first?
People with active skin infections, irritated skin, a history of abnormal scarring or recent use of certain medicines need individual assessment. The best peel depends on the skin condition and skin type; more intense treatment is not always better.
Asthma: Symptoms, Triggers and Management
Learn about asthma symptoms, common triggers and the importance of an individual treatment plan.
What is asthma?
Asthma is a long-term condition in which the airways become inflamed and sensitive. The airways can narrow at times, making it harder to breathe. Symptoms may vary from day to day and can worsen at night or early in the morning.
Common symptoms
- Wheezing or a whistling sound when breathing.
- Coughing, particularly at night or during exercise.
- Chest tightness and shortness of breath.
- Symptoms triggered by respiratory infections, allergens or irritants.
What can trigger asthma?
Triggers vary and may include dust mites, pollen, smoke, air pollution, respiratory infections, exercise or cold air. Identifying personal triggers can help with control.
How is asthma diagnosed?
A clinician reviews symptoms and medical history and may perform spirometry or other breathing tests. These tests help assess airflow and support the diagnosis.
Treatment and prevention
Asthma treatment commonly includes inhaled medicines. Inhaled corticosteroids are important in many treatment plans because they control airway inflammation. The correct inhaler, technique and treatment plan should be selected by a clinician. Do not stop prescribed controller treatment without medical advice.
Reduce exposure to identified triggers, avoid smoking and keep an asthma action plan. Regular follow-up helps assess symptom control.
When is asthma an emergency?
Severe breathlessness, difficulty speaking, blue or grey lips, confusion or rapidly worsening symptoms require emergency medical assistance. Follow the prescribed emergency action plan while seeking help.
Tuberculosis (TB): Symptoms, Testing and Treatment
Learn about TB transmission, warning signs, diagnosis and the importance of completing treatment.
What is tuberculosis?
Tuberculosis is an infectious disease caused by bacteria, most commonly affecting the lungs. It can also affect other organs. TB is preventable and treatable, and early diagnosis helps protect both the patient and the community.
Common symptoms of lung TB
- A persistent cough, sometimes with blood.
- Fever or night sweats.
- Unexplained weight loss and reduced appetite.
- Fatigue and sometimes chest pain.
How does TB spread?
TB bacteria can spread through the air when a person with infectious TB disease of the lungs or throat coughs, speaks or sings. It does not usually spread through sharing food, handshakes or touching surfaces.
How is TB diagnosed?
Assessment may include sputum tests, rapid molecular testing, chest X-rays and other investigations. A positive TB infection test alone does not necessarily mean that a person has active TB disease.
Treatment and prevention
TB requires a specific combination of medicines taken for the prescribed duration. Do not skip doses or stop treatment early without medical advice. Testing and treatment for eligible close contacts, good ventilation and appropriate infection-control measures help reduce transmission.
When should you consult a doctor?
Seek medical evaluation for a persistent cough, unexplained fever, night sweats or weight loss, particularly after contact with someone who has TB. Coughing up blood requires urgent medical assessment.
COPD: Understanding Chronic Lung Disease
Understand persistent breathlessness, chronic cough, lung testing and treatment options.
What is COPD?
Chronic obstructive pulmonary disease (COPD) is a long-term lung condition that restricts airflow and makes breathing difficult. It includes conditions such as emphysema and chronic bronchitis. Symptoms often develop gradually.
Common symptoms
- Shortness of breath, especially during activity.
- A persistent cough or phlegm production.
- Wheezing, chest tightness or reduced exercise tolerance.
- Repeated chest infections or worsening breathing symptoms.
Causes and risk factors
Smoking is a major risk factor. Exposure to indoor cooking smoke, outdoor air pollution, workplace dust and fumes can also contribute. A genetic condition called alpha-1 antitrypsin deficiency causes COPD in a small proportion of people.
How is COPD diagnosed?
A clinician reviews symptoms and exposure history and may request spirometry. This breathing test measures airflow and helps confirm persistent airflow obstruction. Other tests may be required to assess severity or exclude other causes.
Treatment and daily management
Treatment may include inhaled bronchodilators, selected additional inhaled medicines, smoking cessation support, vaccinations, pulmonary rehabilitation and oxygen therapy for people who meet appropriate criteria. Inhaler technique and regular review are important.
Preventing flare-ups
Avoid tobacco smoke, reduce harmful exposure, follow prescribed treatment and discuss recommended vaccinations. Seek medical advice if breathlessness, sputum or cough suddenly worsens.
When to seek urgent care
Severe or sudden breathing difficulty, blue lips, confusion or chest pain requires emergency assessment. Do not assume every episode of breathlessness is caused by COPD.
Pneumonia: Symptoms, Causes and Recovery
Understand this lung infection, its warning signs and how it is assessed and treated.
What is pneumonia?
Pneumonia is an infection that inflames the air sacs in one or both lungs. The air sacs may fill with fluid or pus, which can make breathing uncomfortable and reduce oxygen exchange.
Common symptoms
- Cough, sometimes producing sputum.
- Fever, chills or sweating.
- Shortness of breath and chest pain when breathing or coughing.
- Fatigue and reduced appetite.
Older adults may develop confusion or weakness, sometimes without a prominent fever.
What causes pneumonia?
Bacteria and viruses are common causes; less commonly, fungi may be responsible. The likely cause depends on age, health status, exposure and other clinical factors.
Diagnosis and treatment
A doctor may examine breathing, measure oxygen levels and order a chest X-ray or other tests when needed. Treatment depends on the cause and severity. Antibiotics treat bacterial pneumonia but do not treat viral infections themselves.
Prevention and recovery
Stay up to date with recommended vaccinations, practise hand hygiene, avoid smoking and manage chronic health conditions. Rest, fluids and prescribed treatment support recovery. Recovery time varies, and cough or tiredness may persist for a period after the infection improves.
When to seek medical attention
Seek prompt care for suspected pneumonia. Severe breathlessness, confusion, blue lips or significant chest pain requires emergency assessment. Older adults and people with chronic heart or lung disease may need earlier evaluation.
Lung Function Tests: What Is Spirometry?
Discover how breathing tests help doctors assess airflow and investigate respiratory symptoms.
What is spirometry?
Spirometry is a common pulmonary function test (PFT) that measures how much air a person can breathe out and how quickly they can do so. It helps doctors assess airflow and investigate certain lung conditions.
Why might a doctor recommend it?
- Persistent cough or wheezing.
- Breathlessness during activity.
- Assessment of suspected asthma or COPD.
- Monitoring certain respiratory conditions over time.
What happens during the test?
The patient breathes into a mouthpiece connected to a spirometer, following instructions to take a deep breath and blow out forcefully. Several attempts may be needed to obtain reliable results. A bronchodilator test may be performed before and after medicine in selected cases.
How should you prepare?
Follow the testing centre's instructions about smoking, meals, exercise and inhalers. Do not stop prescribed medicines unless the healthcare team specifically advises you to do so.
Understanding the results
Results are interpreted using age, height, sex-related reference equations, symptoms and other clinical findings. Spirometry can help support a diagnosis but does not independently explain every cause of breathing difficulty.
Is it safe?
Spirometry is generally safe, but forceful breathing can cause temporary dizziness or coughing. Tell the clinician about recent illness, chest pain, recent surgery or other concerns before the test.
Sleep Apnea: Snoring and Breathing During Sleep
Learn why interrupted breathing during sleep needs attention and how it can be diagnosed.
What is sleep apnea?
Obstructive sleep apnea is a condition in which the upper airway repeatedly narrows or closes during sleep. This interrupts normal breathing and may lower oxygen levels and disturb sleep quality.
Common warning signs
- Loud, habitual snoring.
- Pauses in breathing noticed by another person.
- Gasping or choking during sleep.
- Morning headaches, unrefreshing sleep or daytime sleepiness.
- Difficulty concentrating or irritability.
Risk factors
Risk factors include excess body weight, certain airway structures, increasing age and some medical conditions. Sleep apnea can also occur in people who are not overweight.
Diagnosis and treatment
A healthcare professional assesses symptoms and may recommend a home sleep apnea test or an overnight sleep study. Depending on the diagnosis and severity, treatment may include positive airway pressure therapy, weight management when appropriate, selected oral appliances or specialist procedures.
Why should it be treated?
Untreated sleep apnea can affect daytime alertness and is associated with cardiovascular and metabolic health risks. Effective treatment may improve sleep quality and daytime functioning.
When to seek advice
Consult a doctor for repeated breathing pauses, loud snoring with daytime sleepiness or unrefreshing sleep. Avoid driving when excessively sleepy.
Protect Your Lungs: Benefits of Quitting Smoking
Understand how smoking affects the lungs and how professional support can help you quit.
How does smoking affect the lungs?
Tobacco smoke contains harmful chemicals that irritate airways, damage lung tissue and impair the natural mechanisms that clear mucus and particles. Long-term smoking increases the risk of COPD, lung cancer and respiratory infections.
Warning signs of respiratory damage
- Persistent cough or phlegm.
- Wheezing or shortness of breath.
- Reduced exercise tolerance.
- Frequent respiratory infections.
These symptoms can have several causes and should be assessed rather than automatically attributed to smoking.
Benefits of quitting
Quitting reduces exposure to harmful chemicals and lowers future health risks. Circulation and respiratory symptoms may improve over time, although existing lung damage may not completely reverse. Quitting remains beneficial even after many years of smoking.
How can you quit?
Set a quit date, identify triggers and seek support from a healthcare professional. Counselling and evidence-based medicines can improve the chance of success. The best approach depends on individual health and nicotine dependence.
Protecting your lungs
Avoid secondhand smoke, improve ventilation where possible, reduce exposure to harmful dust and fumes, and discuss appropriate vaccinations with your clinician. People with persistent symptoms may need a lung assessment.
When to consult a pulmonologist
Seek medical evaluation for ongoing cough, unexplained breathlessness or repeated chest infections. Coughing up blood, severe breathlessness or sudden chest pain requires urgent medical care.
