Purpose Of Review:
Type 2 diabetes (T2DM) is a major comorbidity of coronavirus disease 2019 (COVID-19) but less is known about COVID-19 and type 1 diabetes (T1DM). Thus, our goal was to review the literature on COVID and T1DM.
Recent Findings:
We identified 21 reports focusing on COVID-19 infections among patients with preexisting T1DM (n = 7), incident T1DM presentations during the COVID-19 quarantine (n = 6), and outpatient management of T1DM during the COVID-19 quarantine (n = 8). These studies showed that patients with preexisting T1DM and COVID-19 infection often present with hyperglycemia and/or diabetic ketoacidosis (DKA). Although the risk of in-hospital mortality may be increased, hospitalization rates among patients with T1DM mirror that of the general population. The numbers of patients presenting with incident T1DM during COVID-19 quarantine have remained stable, but cases with severe DKA may have increased. COVID-19 quarantine has also impacted outpatient T1DM management and studies examining changes in glycemic control have shown mixed results.
Summary:
COVID-19 has important implications for patients with type 1 diabetes, but additional studies with larger numbers of patients and longer term follow-up are needed to confirm the early findings highlighted in this review.

Diabetes Mellitus: Overview and Type I Subtype
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Pathophysiology of Diabetes
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
