Overview Hyperemesis gravidarum (HG) exists on a spectrum of nausea and vomiting in pregnancy (NVP). NVP refers to symptoms of nausea, vomiting or dry retching commencing in the first trimester, with no other cause identified. 1 HG refers to severe, persistent vomiting that may result in malnutrition, dehydration, weight loss and debility due to illness.…

Overview Rhinosinusitis is one of the more prevalent chronic illnesses worldwide, affecting individuals of all ages. It is an inflammatory process that involves the nose and paranasal sinuses. Rhinosinusitis may be acute or chronic. Chronic rhinosinusitis can be subject to acute exacerbations. Rhinitis: Irritation and inflammation of the mucosa lining the nasal cavity Sinusitis: Inflammation…

Overview Gastroenteritis continues to cause significant morbidity in developed and developing countries. The most common cause are viral and bacterial including: Norovirus Enteric adenoviruses E-coli Salmonella spp. and Shigella spp. Campylobater jejuni Diarrhoea: Loose, water like stools that occur with increased frequency and an increased volume of >200g per day Gastroenteritis: >3 or more loose…
View topic ↗Spondylarthropathy
Overview The spondyloarthropathies are a diverse group of inflammatory arthritides that share certain genetic predisposing factors and clinical features. Their most characteristic feature is inflammatory back pain. Enthesitis, another characteristic feature, involves inflammation at sites where tendons, ligaments, or joint capsules attach to bone. Features of Spondylarthropathy Sacroiliac and spinal (axial involvement) Enthesitis at long attachments…

Good places to begin
Explanations learners return to.
Lambert-Eaton Myasthenic Syndrome – pathophysiology, signs and symptoms and treatment
Learn about Lambert-Eaton Myasthenic Syndrome (LEMS), a rare autoimmune disorder affecting neuromuscular transmission due to impaired calcium channel function. This video explains its pathophysiology, hallmark signs such as proximal muscle weakness and autonomic symptoms, along with current diagnostic and treatment strategies.
Atherosclerosis – Pathophysiology
Explore the pathophysiology of atherosclerosis, a chronic condition characterized by plaque buildup within arterial walls leading to narrowed and stiffened arteries. This video explains the processes of endothelial injury, lipid accumulation, inflammation, and plaque formation that contribute to cardiovascular disease.
Bacterial Vaginosis
Learn about bacterial vaginosis, a common vaginal condition caused by an imbalance in the normal bacterial flora. This video explains its symptoms, underlying microbiology, risk factors, diagnostic methods, and available treatments.
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.
Lambert-Eaton Myasthenic Syndrome
Overview Lambert–Eaton myasthenic syndrome (LEMS) is a rare autoimmune disorder of the presynaptic neuromuscular junction. It causes impaired acetylcholine release, producing the characteristic triad of proximal muscle weakness, reduced reflexes and autonomic dysfunction. LEMS may occur as a paraneoplastic syndrome—most commonly associated with small-cell lung cancer (SCLC)—or as a non-tumour-associated autoimmune disorder. Neuromuscular junction: connection…
