In a medical context, the term "environment" refers to the forces or factors outside a person's body, or even any factor influencing a disease that lacks a genetic source. Researchers have studied many possible environmental factors that might contribute to or protect against the development or progression of type 1 diabetes, from viruses, to the intestinal immune system, and even to weight gain. This section summarizes some of these findings, although is not yet comprehensive. 

 

Some environmental factors could be involved in the development of type 1 diabetes even if they are not responsible for the rising incidence of type 1 diabetes in children. Diabetes, after all, has been around since ancient times (Christopoulou-Aletra and Papavramidou 2008). Either increasing risk factors or decreasing protective factors could lead to rising rates of disease, and indeed, many different environmental factors may interact to affect disease incidence.

 

Toxic chemicals are also considered environmental factors, and are addressed in the environmental contaminants section. Very few studies that focus on type 1 diabetes include measurements of contaminant exposures, or even mention environmental contaminants as possible factors in disease development at all. Yet, a variety of environmental factors that have been associated with type 1 diabetes may be influenced by contaminant exposures, from viruses, to the intestinal immune system, and even to weight gain. These interactions are included on the pages within this section. See the list of subpages below or to the side for a list of these pages.

 

See the hypotheses page for ideas that researchers have proposed to explain the rising incidence of type 1 diabetes disease in children, how the disease develops, and how various environmental factors may act in tandem.
