Health Essentials: Your Guide to Understanding Medical Conditions
Personal Health Assessment Tool
Understanding your basic health metrics can help you have more informed conversations with your healthcare provider. This simple calculator provides insights based on standard health measurements, but remember—these are just starting points for discussion, not diagnostic tools.
Your Health Assessment Results
Heart & Circulatory Conditions
Your cardiovascular system—heart, blood vessels, and blood—forms the essential highway that delivers oxygen and nutrients throughout your body. Understanding these conditions can help you recognize warning signs and take preventive steps.
Heart Attack
When blood flow to part of your heart becomes blocked, heart muscle begins to die. I explain the warning signs (which can be surprisingly subtle, especially in women), what happens during a heart attack, and how to reduce your risk factors.
Coronary Heart Disease
The most common type of heart disease develops when your coronary arteries narrow or become blocked. I explore how this condition develops over decades, often silently, and the lifestyle changes that can dramatically reduce your risk.
Atrial Fibrillation
This irregular heart rhythm affects millions but remains underdiagnosed. I explain how this chaotic electrical activity impacts heart function, why it increases stroke risk, and the treatment approaches from medication to minimally invasive procedures.
Deep Vein Thrombosis
Blood clots forming in deep veins (usually in the legs) can be life-threatening if they break loose. I cover the risk factors many people don't know about, warning signs beyond leg pain, and when to seek immediate medical attention.
Congenital Heart Disease
Heart defects present at birth range from simple to complex. I explain the most common types, how they affect heart function, and the remarkable advances in treatment that have transformed outcomes for children born with these conditions.
Hypertension (High Blood Pressure)
Often called the "silent killer," hypertension rarely causes symptoms while damaging vital organs. I break down what your blood pressure numbers actually mean, why even mild elevation matters, and evidence-based approaches to bring it under control.
Abdominal Aortic Aneurysm
When the major blood vessel supplying your abdomen and lower body bulges dangerously, it often causes no symptoms until a life-threatening rupture. I explain who should be screened, how they're monitored, and treatment options.
Arterial Thrombosis
Blood clots forming in arteries can rapidly cut off blood supply to vital organs. I explain the difference between arterial and venous clots, why they require different treatments, and prevention strategies that could save your life.
Respiratory Conditions
Your respiratory system—lungs, airways, and blood vessels—brings oxygen into your body while removing carbon dioxide. These conditions affect your breathing and overall oxygen supply.
Asthma
This chronic condition causes airways to narrow and produce extra mucus, making breathing difficult. I cover how to identify triggers, recognize worsening symptoms, and build an effective management plan that lets you live fully despite asthma.
Chronic Obstructive Pulmonary Disease (COPD)
This progressive lung disease makes breathing increasingly difficult over time. I explain the differences between emphysema and chronic bronchitis (the two main forms of COPD), management strategies, and why early intervention matters.
Bronchitis
Inflammation of the bronchial tubes can be acute (short-term) or chronic (ongoing). I explain the typical progression of symptoms, when antibiotics are and aren't helpful, and how to distinguish bronchitis from more serious conditions.
Bronchiectasis
When airways become abnormally widened and scarred, mucus accumulates and creates a breeding ground for infections. I cover the surprising causes, why diagnosis is often delayed, and treatment approaches that break the infection cycle.
Asbestosis
Lung scarring from asbestos exposure typically develops decades after exposure. I explain which occupations carry highest risk, how doctors diagnose this condition, and palliative approaches that can improve quality of life.
Cough
Though not a disease itself, persistent cough often signals an underlying condition. I help you decode different types of coughs, understand when self-care is appropriate versus when to see a doctor, and effective management strategies.
Croup
This childhood condition causes a distinctive "barking" cough that can frighten parents. I explain why it happens, how to distinguish it from more serious conditions, and when home management is sufficient versus when to seek medical care.
Digestive & Gastrointestinal Conditions
Your digestive system breaks down food into nutrients your body can absorb while eliminating waste. These conditions affect digestion, nutrient absorption, or regular elimination.
Appendicitis
Inflammation of the appendix requires prompt medical attention. I explain how symptoms typically progress (often starting around the navel before moving to the lower right abdomen), diagnostic approaches, and treatment options including when surgery is necessary.
Constipation
Occasional constipation affects most people, but chronic issues signal something's wrong. I explore the many causes beyond simply "not enough fiber," when medication might be causing the problem, and evidence-based remedies that actually work.
Crohn's Disease
This inflammatory bowel disease can affect any part of your digestive tract. I explain the complex interplay of genetic and environmental factors, the often-subtle initial symptoms, and the multi-faceted treatment approach that's transformed outcomes.
Diverticular Disease and Diverticulitis
Small pouches that bulge outward through weak spots in your colon (diverticula) can become inflamed or infected. I cover why these develop, how to reduce your risk, and the dramatic difference between uncomplicated diverticulosis and acute diverticulitis.
Bowel Polyps
These small growths on the lining of the colon or rectum are typically harmless but can develop into cancer. I explain the different types, screening recommendations, removal procedures, and follow-up care to minimize colorectal cancer risk.
Bowel Incontinence
Though rarely discussed openly, this condition affects millions and significantly impacts quality of life. I cover the many causes beyond aging, the diagnostic process, and the surprising number of effective treatments available today.
Coeliac Disease
This immune reaction to eating gluten damages the small intestine and prevents nutrient absorption. I explore the wide range of symptoms beyond digestive issues, why diagnosis is often missed, and how dietary management has evolved.
Acute Pancreatitis
Sudden inflammation of the pancreas can be life-threatening. I explain the most common causes, why the pain is typically so severe, treatment approaches, and preventive measures to avoid recurrence.
Cancer & Oncological Conditions
Cancer develops when cells begin to grow uncontrollably. Early detection often significantly improves outcomes, making awareness of warning signs and screening recommendations vitally important.
Bowel Cancer
Also called colorectal cancer, this common cancer often develops slowly over years. I explain the screening tests that can catch it early or even prevent it entirely, warning signs people often attribute to hemorrhoids, and treatment advances improving survival rates.
Breast Cancer (female)
Beyond being the most common cancer in women, breast cancer encompasses several different types with varying treatments and prognoses. I cover risk assessment, the latest screening guidelines, and the personalized treatment approaches transforming care.
Breast Cancer (male)
Though rare, men can develop breast cancer too, and diagnosis is often delayed due to low awareness. I explain risk factors specific to men, symptoms that shouldn't be ignored, and treatment considerations for male patients.
Brain Tumours
These growths in or around the brain vary widely in their behavior and treatment. I explain the difference between primary and secondary tumours, how location affects symptoms and treatment options, and advances in surgical and radiation techniques.
Cervical Cancer
Nearly always caused by HPV infection, cervical cancer is highly preventable with screening and vaccination. I explain the Pap test and HPV testing recommendations, warning signs, and the remarkably high cure rates when caught early.
Acute Myeloid Leukaemia
This aggressive blood cancer requires prompt treatment. I cover how it differs from other leukemias, why symptoms can appear suddenly, and the intensive treatment approach that offers the best chance of remission.
Chronic Lymphocytic Leukaemia
The most common adult leukemia often progresses so slowly that treatment isn't immediately needed. I explain the "watch and wait" approach that surprises many patients, signs indicating treatment should begin, and how therapeutic options have expanded dramatically.
Bile Duct Cancer (Cholangiocarcinoma)
This rare cancer affecting the bile ducts is challenging to diagnose early. I explore risk factors including liver flukes in certain regions, why jaundice is often the first noticeable symptom, and treatment options including specialized radiation approaches.
Brain & Neurological Conditions
Your nervous system—brain, spinal cord, and nerves—controls virtually everything your body does. These conditions affect cognition, movement, sensation, or other neurological functions.
Stroke
When blood flow to part of the brain is blocked or when a blood vessel ruptures, brain cells begin to die. I cover the FAST warning signs, why immediate treatment is crucial, and the remarkable recovery possible with prompt care.
Alzheimer's Disease
The most common cause of dementia involves progressive brain changes that affect memory, thinking, and behavior. I explain current understanding of its development, the difference between normal aging and concerning symptoms, and care approaches.
Epilepsy
This brain disorder causes recurring seizures that vary widely in appearance. I cover the different seizure types (many don't look like the dramatic convulsions people expect), diagnostic approaches, and the multiple treatment options providing seizure control for most patients.
Concussion
This mild traumatic brain injury temporarily affects brain function. I explain why symptoms might not appear immediately, the critical importance of proper recovery (especially in children and teens), and current guidelines for returning to activities.
Migraine
Far more than "just a headache," migraine is a neurological disorder causing severe, often debilitating symptoms. I cover the four distinct phases, triggers identification strategies, and the exciting new preventive treatments revolutionizing care.
Parkinson's Disease
This progressive nervous system disorder affects movement and causes numerous non-motor symptoms. I explain the underlying brain changes, early symptoms often missed or misattributed, and the multidisciplinary approach offering best quality of life.
Cerebral Palsy
This group of disorders affects movement, muscle tone, and posture due to abnormal brain development or damage. I explore the different types, early intervention approaches, and the personalized therapy plans that maximize functional abilities.
Coma
This state of prolonged unconsciousness can result from various causes. I explain the Glasgow Coma Scale used to assess severity, what medical teams are monitoring, and factors that influence recovery potential.
Infectious Diseases
Infections occur when organisms like bacteria, viruses, fungi, or parasites enter your body and cause disease. Understanding transmission, prevention, and treatment is essential for managing these conditions.
Coronavirus (COVID-19)
This viral infection ranges from mild to severe and continues to evolve. I cover the current understanding of transmission, symptom patterns, testing options, treatment approaches, and prevention strategies including vaccination and boosters.
Common Cold
This viral infection of your nose and throat is usually harmless but annoying. I explain why antibiotics don't help, which remedies actually have evidence behind them, and when complications might require medical attention.
Chickenpox
This highly contagious viral infection causes an itchy rash with fluid-filled blisters. I cover why vaccination has dramatically reduced cases, why adults typically experience more severe symptoms, and when antivirals might be recommended.
Sepsis
This life-threatening response to infection can lead to tissue damage, organ failure, and death if not promptly treated. I explain who's at highest risk, the early warning signs many people miss, and why rapid treatment is absolutely critical.
Dental Abscess
This painful collection of pus can form in different parts of a tooth or gum. I explain why this infection should never be ignored, how it's treated, and preventive steps to avoid recurrence.
Cellulitis
This common bacterial skin infection can rapidly spread and become serious. I cover risk factors many people don't realize they have, when to seek medical attention, and how to prevent recurrent infections.
Clostridium Difficile
This bacterial infection can cause symptoms ranging from diarrhea to life-threatening inflammation of the colon. I explain its strong association with antibiotic use, why recurrence is common, and new treatment approaches showing promise.
Bacterial Vaginosis
This common vaginal infection occurs when the normal bacterial balance is disrupted. I cover the risk factors, why it often recurs despite treatment, and strategies to restore healthy vaginal flora.
Finding Reliable Health Information
In an era of information overload, finding trustworthy health resources can be challenging. Consider these tips when researching health topics:
- Check the source—government health agencies, academic medical centers, and major health organizations typically provide evidence-based information
- Look for recent publication dates, especially for rapidly evolving topics
- Be wary of websites primarily selling products or services related to the condition
- Verify information across multiple reputable sources
- Discuss what you find with healthcare providers, who can help interpret information in the context of your specific situation
Health literacy isn't just about understanding medical terms—it's about having the confidence to ask questions, evaluate information, and participate actively in your own care. My hope is that these resources help empower you to have more productive conversations with your healthcare team and make informed decisions about your wellbeing.
