100+ condition draft library
Search across heart, lung, gut, liver, kidney, infections, STIs, autoimmune, bone, skin, brain, eye, ear, endocrine, blood and mental health conditions. This is a treatment map for an established or clinician-suspected diagnosis, which may still be wrong or incomplete. It is not a way to self-diagnose from the internet or AI.
Important caveats
Names, symptoms and treatment lists are educational prompts after a diagnosis is established or suspected by a clinician. Diagnoses can still be wrong, incomplete or out of date; new red flags or poor response should trigger review.
Reflux, indigestion, gallbladder pain and panic can mimic heart disease. Chest pressure, breathlessness, sweating, fainting or pain radiating to jaw/arm/back needs urgent assessment.
For major surgery, lifelong immune therapy, cancer treatment, ablation, device implantation, long-term opioids or uncertain diagnosis, a second specialist opinion can be wise.
Clinical trial links open live searches. Trial drugs are not automatically better or safer, and many are only available in research settings.
Babies, young children, older adults, pregnant people and immunocompromised patients can deteriorate faster and may need earlier testing, antivirals, antibiotics or hospital care.
Many conditions need vaccines, procedures, surgery, rehabilitation, diet, exercise, sleep, psychology, wound care, infection control or social support.
Measles, diphtheria, tetanus and pertussis can return when vaccination rates fall. Check local vaccine schedules with a clinician or public health source.
Doctor-guided care
Over-the-counter medicines, vitamins, supplements and alternative treatments can be useful in some settings, but they can also delay diagnosis, interact with medicines or cause harm. Use them with clinical guidance, especially when symptoms persist, worsen or do not fit a simple explanation.
Simple options such as paracetamol/acetaminophen can be useful for short-term pain or fever, but dosing matters. Ibuprofen, naproxen and similar anti-inflammatory drugs can worsen ulcers, reflux, kidney disease, heart failure, blood pressure and bleeding risk.
Some medicines are reasonable in the right setting, such as sublingual ondansetron for nausea or loperamide for non-bloody diarrhea. If symptoms persist, are severe or you are unsure, seek GP, clinic, specialist or emergency care.
More is not always safer. Vitamin A, D, iron, potassium, iodine and many herbal products can be toxic or interact with prescribed medicines.
Complementary care should not replace urgent assessment, cancer workup, antibiotics for serious infection, insulin, anticoagulation or proven emergency treatment.
Persistent bleeding, weight loss, anemia, new lumps, progressive swallowing trouble, changing moles, night sweats or ongoing pain need proper investigation before disease progresses too far.
If the course is unusual, treatment is not working, symptoms evolve or the diagnosis was made without appropriate tests, ask for reassessment or a second opinion.
Some problems sit between specialties. Neurological symptoms may be endocrine, metabolic, vascular, autoimmune or medication-related; endocrine symptoms may be neurological or psychiatric. A different specialist type can change the answer.
Many tendon, joint and nerve problems improve with time, physiotherapy, splints or injections. Surgery is usually for clear structural problems, progression or failure of appropriate non-surgical care.
Personal story
This site grew from the experience of trying to make sense of symptoms when the usual tests were normal and the usual diagnoses did not quite fit.
The journey started with fainting and symptoms that seemed cardiac or neurological. A cardiologist found the usual tests normal. A neurologist also found no clear answer. Two endocrinology opinions did not reach the diagnosis. The eventual answer was an insulinoma, a very rare insulin-producing pancreatic neuroendocrine tumour. During documented hypoglycaemia, the insulin level was about 40 times the upper limit of normal.
The turning point was persistence: recognizing that the episodes still needed an explanation, then convincing a third expert professor to order specialized imaging, including a Dotatate PET scan. That scan helped find the lesion. Rare diseases are difficult because most clinicians quite reasonably start with common causes, but a rare diagnosis can still be real when the pattern keeps pointing there.
This is only one example of a wider problem. Some diseases are missed, diagnosed late or given the wrong label because they are rare, because early tests are normal, because symptoms cross specialty boundaries, or because the right measurement is not captured at the right time. People with hypoglycaemia, for example, can look faint, confused, anxious, neurological or psychiatric if low glucose and inappropriate insulin are not documented during an episode.
The lesson is not to self-diagnose from the internet or AI. The lesson is to use information to ask better questions, keep records, notice patterns, seek the right specialty, and ask for reassessment or a second opinion when the diagnosis does not fit. Normal tests can be reassuring, but they do not always close the case.

Hospital expertise
Many treatments can happen locally. But rare diseases, complex operations, advanced imaging, transplant, cancer subtyping, clinical trials and multidisciplinary care may require a hospital with particular expertise.
Emergency care should not wait for a perfect hospital. Once stable, ask whether referral to a disease-focused centre would change options.

Use plain terms like “reflux”, “AF”, “eczema”, “kidney stone”, “frozen shoulder”, “carpal tunnel”, “depression”, “MASH” or “glaucoma”.
Area or body part
This filters the library by broad body region for an established or suspected diagnosis, which still may be wrong. It does not diagnose pain. Chest, upper-abdominal, back, jaw or arm symptoms can still be heart, lung, vascular or nerve disease.
Reference hubs
This draft uses guideline and registry hubs rather than pretending a short website can replace a clinician's full workup. Disease cards link to a reference hub or article plus a live ClinicalTrials.gov search; this is a starting bibliography, not an exhaustive evidence review. Last checked: 5 June 2026.
