1 · Diabetic ketoacidosis
High sugar without enough insulin pushes the body to burn fat in a toxic acidic way. Watch for: intense thirst and urination, nausea and abdominal pain, deep rapid breathing, and breath smelling of acetone (nail polish remover). It strikes type 1 diabetics especially — and can be diabetes' first-ever appearance in a child or young adult.
2 · Thyroid storm
An overactive thyroid spinning out of control — often after infection or stopped treatment: high fever, severe palpitations, agitation and confusion, vomiting. Rare, but fatal without rapid treatment.
3 · Adrenal crisis
Its greatest danger is striking those least aware of it: anyone on months of steroid tablets who stops suddenly, or an adrenal-insufficiency patient hit by infection. Signs: low blood pressure, vomiting, abdominal pain, and profound exhaustion up to collapse.
Life-preserving rules
- Type 1 diabetic + vomiting or abdominal pain = check sugar and ketones, and go to the ER if they are high.
- Never stop long-term steroids suddenly — they are tapered gradually under a doctor's supervision.
- A steroid or adrenal patient with fever or a stomach bug usually needs a dose increase — the "sick day rules" — ask your doctor about them today, before you need them.
Worth knowing
A medical bracelet or wallet card saying "adrenal insufficiency — needs emergency steroids" or "type 1 diabetes" can save the ambulance crew precious diagnostic minutes while you are unconscious.
