Where it strikes
Medical treatment
- Metformin first — cheap, with decades of safety data trials support
- SGLT2 inhibitors and GLP-1 agonists — fewer heart and kidney events, at a price, and the trials are run by the makers trials support
- Insulin when the pancreas gives out trials support
- Statin and ACE inhibitor, weighed on your own risk mixed evidence
- Yearly eye, foot and kidney checks — cheap and they catch damage early trials support
- Tirzepatide — approved (FDA, EMA 2022) trials support
Natural & lifestyle
- Weight loss of 10–15 kg can put it into remission — about half of DiRECT participants at a year
- low-carbohydrate or Mediterranean diet
- 150 min exercise + resistance training
- sleep repair
- fibre
- walking after meals
Emerging & experimental
- Retatrutide
- closed-loop insulin systems
- islet cell transplants from stem cells (VX-880)
- bariatric surgery as metabolic therapy
Alternative, off-label & anecdotal
Approaches used outside the guidelines, with what their supporters report and what testing has found so far.
- Berberine — trials lower HbA1c about as much as metformin; it interacts with many drugs mixed evidence
- Low-carbohydrate and ketogenic diets — trials show lower HbA1c and fewer drugs needed; long-term data are limited mixed evidence
- Intermittent fasting — small trials, remission in some early / small studies
- Cinnamon — meta-analyses show small falls in fasting glucose; effect on HbA1c unclear mixed evidence
- Bitter melon, fenugreek, gymnema — small trials, small effects early / small studies
- Apple cider vinegar — tiny glucose effects in small studies anecdotal / traditional
