Sources
Every article on this website ends with a section headed "Where this comes from", listing the public pages it was written from, linking straight to them, and showing the date we last opened them. This page explains which organisations those come from and why we limit ourselves to them.
The organisations we use
- CDC — the US Centers for Disease Control and Prevention, for public-health baseline material on managing sick days with diabetes, on influenza and people with diabetes, and on the immune system. cdc.gov
- American Diabetes Association — for the structure of planning sick days in advance with a care team, and what a sick-day kit is for. diabetes.org
- NIDDK — the National Institute of Diabetes and Digestive and Kidney Diseases, part of the NIH, for material on managing diabetes day to day and on when to check things with a care team. niddk.nih.gov
- MedlinePlus — the US National Library of Medicine's consumer health service, for plain-language background on colds, influenza, dehydration, medicines, over-the-counter medicines, personal health records, caregivers, and emergency medical services. medlineplus.gov
Why only these
All four are US public bodies or major non-profits that publish freely readable pages, keep them current, and can be checked by you directly. That last point matters most: a source you cannot open is not a source, it is a claim.
We do not build pages from journal abstracts, press releases, news coverage, or other health sites. A single study is not clinical consensus, and neither is a search ranking. We also do not automatically collect medical news, which is a deliberate decision rather than a limitation.
How we use them
Sources are background for the shape of a page — which topics matter, what a care team will ask about, what a plan usually covers. We do not copy sentences from them, and we do not carry over their clinical specifics. Where a source contains numbers, thresholds, frequencies, or dosing, we leave all of that on the source page and link you to it rather than restating it here. Our Editorial Policy explains why.
This means a source page will often contain more clinical detail than the page here that cites it. That is intentional. Read the original, and take what you find there to your own care team.
Checking dates
The date shown on each article is the date we last opened those pages and confirmed the material we relied on was still there. It is not a claim about when the source itself was last revised — where a source publishes its own review date, read that on the source page.
Public health pages move. If a link on this site is dead, redirects somewhere unexpected, or no longer supports what the page around it says, tell us at and see Corrections.
What we are not
this website is not affiliated with, endorsed by, or connected to the CDC, the American Diabetes Association, NIDDK, the National Library of Medicine, or any other organisation named on this site. We link to their public pages; that is the whole of the relationship. Nothing here has been reviewed by a clinician.
