Diabetes Mellitus Type II
Overview Diabetes Mellitus type II is a progressive disorder defined by deficits in insulin secretion and action (insulin resistance). 1 in 12 people have diabetes (50% do not know they have it). Diabetes type II accounts for over 90% of all diabetes cases. The remaining 10% include type I diabetes. People with type II diabetes…
View topic ↗Addison's Disease
Overview Addison's disease is a disease characterised by adrenal insufficiency. Adrenal insufficiency results in a decrease of the adrenal gland hormones: mineralocorticoids, glucocorticoids and to an extent androgens. There are many causes of addison's disease. The most common cause in the developed world is autoimmune (approximately 70% cases). Signs and symptoms of adrenal sufficiency don't…
View topic ↗Aortic Regurgitation (incompetence)
Overview Aortic regurgitation (AR) is backward flow of blood from the aorta into the left ventricle during diastole because the aortic valve does not close completely. AR may result from disease of the valve leaflets, dilatation of the aortic root or both. Chronic AR causes progressive left-ventricular volume overload and dilatation, whereas acute severe AR…
View topic ↗Cushing's Disease
Overview Cushing's disease is a ACTH dependent syndrome characterised by excess corticosteroid production from the adrenal glands. It is ACTH dependent because it is triggered by an ACTH-secreting pituitary tumour. Cushing's syndrome is an over arching term to describe hypercortisolaemia dependent of independent of ACTH. Adrenal Cushing's syndrome is different because it is hypercortisolaemia independent…

Overview Antiphospholipid Syndrome (APS) is an acquired autoimmune thrombophilia characterized by recurrent venous or arterial thromboses and/or pregnancy morbidity in the presence of persistent antiphospholipid antibodies (aPL). APS may occur as a primary condition or secondary to systemic lupus erythematosus (SLE). Prevalence of aPL in the general population is ~2%, but true APS is rare…
View topic ↗Sexual Transmitted Infection
Overview Sexually transmitted infections (STI) are a significant public health worldwide. STI can result in chronic disease, pregnancy complications, infertility, and even death. Globally, congenital syphilis is still a leading cause of stillbirth and neonatal death. Antibiotic-resistant Neisseria gonorrhoeae continues to be a significant public health concern. Chlamydia trachomatis infection is the most frequently reported…
View topic ↗Anal Abscess
Overview Anorectal abscess is an infection of soft tissue around the anus. It causes severe perianal pain and swelling. 30% to 70% of anorectal abscesses are associated with an anorectal fistula. It is two times more likely to present in males. 1 2 Anal Abscess Anorectal abscess: collection of pus in anorectal spaces resulting from…

Hiccups in Babies: Why do they do it so much?
Hiccups in infants are common and usually harmless, often caused by feeding, swallowing air, or a developing digestive system. Most infant hiccups resolve on their own and don’t require treatment, but burping and upright positioning can help reduce episodes.
Mental Health
Explore the fundamentals of mental health, including its impact on emotional, psychological, and social well-being. This video discusses common mental health conditions, factors that influence mental wellness, and the importance of early recognition and support.
Endocrinology – Calcium and Phosphate Regulation
Understand calcium and phosphate regulation in endocrinology, focusing on the roles of PTH, vitamin D, and calcitonin. This video breaks down hormonal control mechanisms and their impact on bone, kidney, and gut physiology for clear clinical insight.
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.

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…
