Risk factors for GDM include maternal obesity, advanced maternal age, family history of type 2 diabetes mellitus (T2DM), diagnosis of Polycystic ovarian syndrome (PCOS), and a prior history of GDM. GDM has both implications for the pregnant person and the offspring with increased risks of adverse pregnancy outcomes as well as increased chance of developing T2DM later in life. The first-line treatment for GDM includes behavior modification followed by pharmacologic therapy with insulin being preferred medication of choice. Standard of care for the management of continuous glucose monitors (CGM) currently includes self-monitored blood glucoses or finger sticks 4× per day and this can increase stress and anxiety in pregnancies. Continuous glucose monitorings have been used commonly in nonpregnant diabetic patients and patients with type 1 diabetes but their use in patients with GDM are increasing. Although there are no specific Continuous glucose monitoring targets for patients with GDM, CGMs have been used to help determine normative data in patients without GDM, which has helped provide expert opinion on GDM targets. In research studies, CGMs have also been used to explore glycemic profiles for patients early in pregnancy who go on to develop GDM as well as looking at adverse pregnancy outcomes in patients with higher Continuous glucose monitoring metrics. Using CGMs has the potential to provide more information about glycemia, ultimately leading to treatment recommendations in patients with GDM with the ultimate goal to improve adverse pregnancy outcomes and improve health and well-being at large.</p>","PeriodicalId":11159,"journal":{"name":"Diabetes technology & therapeutics","volume":" ","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144559484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the glycemic impact of snacking after dinner (\"bedtime snacking\") without prandial insulin administration has not been previously explored. We present an analysis of the impact of delayed mealtime insulin administration and bedtime snacking on inpatient glycemic control. <b><i>Research Design and Methods:</i></b> We conducted a post hoc analysis from the In-Fi study: a randomized controlled trial comparing Fiasp versus insulin aspart (Novolog) in inpatients with type 2 diabetes. Glycemic outcomes were assessed using the Dexcom G6 PRO continuous glucose monitoring (CGM). We analyzed CGM and insulin administration data from 122 randomized subjects who completed the primary study protocol, which included wearing a CGM for ≥4 meals. This analysis evaluates the impact of delayed mealtime insulin administration and bedtime snacking on glucose control. <b><i>Results:</i></b> Four-hour postprandial time in range (TIR<sub>70-180</sub>) was 48% for insulin boluses administered before meals (<i>n</i> = 149) versus 24% when a meal bolus was delayed for >5 min after a meal (mean delay 58.7 min; <i>n</i> = 112; <i>P</i> < 0.001). Bedtime snacking (9 pm-12 am) was associated with significantly higher fasting glucose the next morning (35.2 mg/dL, standard error [SE] = 15.4, <i>P</i> = 0.026) and with a reduced overnight (9 pm-6 am) TIR<sub>70-180</sub> (31.9%, SE = 8.06, <i>P</i> < 0.001), adjusting for bedtime sensor glucose. Bedtime snacking was associated with higher overnight glucose standard deviation (12.3 mg/dL, SE = 3.46, <i>P</i> < 0.001) and with higher overnight glucose percentage coefficient of variation (3.6%; SE = 1.7, <i>P</i> = 0.044), adjusting for initial bedtime sensor glucose. <b><i>Conclusions:</i></b> Delayed mealtime insulin administration and bedtime snacking without insulin administration are significant causes of postprandial and overnight hyperglycemia in hospitalized inpatients. Adjustments in mealtime insulin protocols, attention to food intake, and the potential inpatient adoption of technology, such as CGM and automated insulin delivery systems, are needed to address this shortcoming in inpatient diabetes care.</p>","PeriodicalId":11159,"journal":{"name":"Diabetes technology & therapeutics","volume":" ","pages":"511-516"},"PeriodicalIF":5.7,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143604173","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
