Irritable Bowel Syndrome (IBS)
Overview Complex chronic syndrome characterised by recurrent abdominal pain and bowel dysfunction, in the absence of a structural abnormality. It is not associated with an increase in mortality, however, it is associated with substantial morbidity and a significant decrease in an individual’s quality of life. IBS belongs to a group of disorders collectively known as Functional Gastrointestinal Disorders.…

X-linked Agammaglobulinaemia (XLA / Bruton’s Disease)
Overview X-linked agammaglobulinaemia (XLA) is a rare primary immunodeficiency caused by mutations in the Bruton’s tyrosine kinase (BTK) gene , leading to failure of B-cell maturation. It results in profound hypogammaglobulinaemia and susceptibility to recurrent bacterial infections, particularly with encapsulated organisms. It usually presents after 6 months of age (once maternal IgG wanes). Prevalence is…

Otitis Externa
Overview Otitis externa is an acute or chronic inflammation of the external auditory canal, which extends from the tympanic membrane to the pinna. It is predominantly a localized bacterial infection caused by a breakdown in the natural protective barriers of the ear canal—namely cerumen, an acidic pH, and an intact epithelial lining. Frequently referred to…

Stroke (Ischaemic and Haemorrhagic)
Overview Third most common cause of death worldwide and most common cause of neurological disability. It is subdivided into ischaemic stroke (caused by vascular occlusion or stenosis) and haemorrhagic stroke (caused by vascular rupture, resulting in intra-parenchymal and/or subarachnoid haemorrhage). Stroke: Acute onset of a focal neurologic deficit due to a cerebral infarction or hemorrhage. Transient Ischaemic…

Enteropathic Arthritis
Overview Enteropathic arthritis is a subtype of spondyloarthropathy associated with inflammatory bowel disease (IBD), particularly Crohn’s disease and ulcerative colitis. It affects up to 20% of IBD patients, with a variable presentation involving axial and/or peripheral joints. The arthritis may run parallel to intestinal disease activity or occur independently, often with enthesitis or dactylitis. It…

Diabetes Mellitus type I
Overview Type 1 Diabetes Mellitus (T1DM) is a chronic, autoimmune metabolic disorder characterized by the progressive, T-cell-mediated destruction of insulin-producing pancreatic beta-cells within the Islets of Langerhans. This severe loss of functional beta-cell mass results in absolute insulin deficiency, leaving affected individuals entirely dependent on exogenous insulin for survival. Without sufficient insulin, tissues cannot take…

Alcohol Withdrawal Delirium (delirium tremens)
Overview Alcohol withdrawal delirium , traditionally called delirium tremens , is the most severe manifestation of alcohol withdrawal. It is characterised by acute , fluctuating disturbances in attention , awareness and cognition accompanied by marked autonomic hyperactivity. It is a medical emergency requiring hospital admission , intensive monitoring and prompt benzodiazepine treatment. 1–3 Symptoms typically…

Cephalosporin
Explore cephalosporins, a widely used class of β-lactam antibiotics, including their mechanism of action, spectrum of activity, and classification into generations. This video covers clinical uses, resistance patterns, and important considerations for safe and effective treatment.
Mitral Valve Prolapse
Mitral valve prolapse is described as bulging of one or more of the mitral leaflets into the left atrium in systoleIt is said to be the MOST common valvular abnormality and often benign. 5% of the population and more common in females. Mitral valve prolapse is a cause of mitral regurgitation. In men, MVP is…
Idiopathic Pulmonary Fibrosis – pathophysiology, signs and symptoms, investigation and treatment
Learn about idiopathic pulmonary fibrosis, a chronic lung disease characterized by progressive scarring of the lung tissue. This video covers its pathophysiology, clinical presentation, diagnostic approach, and current treatment strategies aimed at slowing disease progression and managing symptoms.
Our mission
Medical science is complex. Understanding it should feel possible.
Armando Hasudungan turns difficult medical science into clear visual explanations and connected learning experiences—so learners can see the whole picture, remember what matters and find a clearer way forward.
See it clearly
Turn abstract processes and invisible relationships into something the learner can picture.
Connect the pieces
Build understanding around how concepts fit together—not a pile of isolated facts.
Make it useful
Help learners move from explanation to recall, revision and the next logical step.
What clarity feels like
When the topic stops being a blur.
Learners do not come back because the subject became easy. They come back because the explanation gave them a picture they could work with.
“Armando's teaching style gives me the foundational knowledge.
Jessica Payne-Burnett
Medical Student, Charles Sturt University
“The notes I make during his videos help me retain everything better.
Ayesha RaiStudent, Islamabad Medical and Dental College
“The drawings are amazing and super easy to remember.

Coming soon: the AH study platform
The explanation is only the start.
The free library helps you find a clear explanation. The AH platform is being built to help you connect the resources, follow a clearer path and check what actually stuck.
- Watch in a focused, ad-free study environment.
- Move between connected videos, notes, diagrams and questions.
- Know what belongs next instead of rebuilding the study path yourself.
- Test your understanding while the topic is still fresh.
New and worth a look
Keep building the picture.
Chronic inflammatory demyelinating polyneuropathy (CIDP)
Overview Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is an acquired immune-mediated disorder of peripheral nerves and nerve roots, causing demyelination, impaired nerve conduction, weakness, sensory disturbance and reduced or absent reflexes. Typical CIDP causes progressive or relapsing symmetrical proximal and distal weakness with sensory loss developing over at least 8 weeks . This time course helps…
