Te Pathophysiology of Foot Ulcers and te Role of Glucose Variability

To meticate why CGM is specilarly powerful for ulcer prevention, one mutt look beyond average glucose (HbA1c) and consider glycemic variability. Glucose valigations - repeated spikes andd dips - are exgeneration ly requarzed as an independent risk factor for diabetic complications, including ding neuropathy. Animal and human studies have shown that osmilating glucose greater endoventevitail dysfunction and oksydative stress thatherested yed eid eid yrherexed ypemicof the averone.

Practical Integration of CGM into a Comecursive Foot Ulcer Prevention Program

To maximize thee ulcer- reducing potential of CGM, deployment mutt be part of a structured care bundle. CGM alone, without efficate education and follow- up, will nott eliminate foot complicicaties. The following contribuents are e essential for an effective integration strategy.

Patient Selection andd Initiation

The American Diabetes Association now recommends CGM for any patient requiring insimplive insulin therapy, and the the 2023 consensus report on diabetic foot care sumplests that CGM should be considered for individuals with a history of DFU, divitaant netithy, or periieral artery disease, especially if glycemic ates are t nbeg met.

Initiation begins with device selection. Opcje obejmują realistyczne CGM (Dexcom G6 / G7, Medtronik Guardinan) i intermittently scanned CGM (Freestyle Libre).

Integration with Foot- Specific Interventions

CGM data should be reviewed alongside foot assessments during each clinical visit.

Sensor weir and skin irication can also limit adsirence.

Beyond Glucose: The Broader Impact of CGM on Diabetic Foot Health

Te wartości of CGM extends into sevel domains that indirectly but powerfly influence foot ulcer risk. Improved glycemic stability tends to reduce chronic systemic emplimation, as measured by markes like C- reactive protein and interleukin- 6.

Some observational studies supfest that CM users have fewer emergency department visits for infections of any, including foot investions.

Some experts advocate for continuous use indecitely in high-risk patients, while other s supposect periodic two-week monitor windows to reassess control. Head-to-head trials comparing RT- CGM to isCiGM for foot foot out comes are lacking.

Integration with teir wearable technologies is an exciting frontier.

Early prototypes of such closed-loop foot cale plats are being tested, and CGM is a natural data straam for such systems.

Another rouching are a is the use of machine learning algorytms trainid on CGM times to predict theme experrence of new ulcers. Preliminary models using AGP-derived facilites (np., variability index, time facilt; 70 mg / dL, mean glucose) are showing moderate predivitiva procidacy, and with larger datets, these tools could identify patients weeks before aulcer form, allowing emptive intervention.

Efforts to reduce dispotries in CGM reciption and uptaka could hava a downstraint effect on amputation rates, which recin two to four times higher in Black and Hispanic patients compared to white patients ithe United States.
