Glucose tolerance refers to the body's ability to regulate and maintain healthy levels of glucose (sugar) in the blood. This area of research focuses on understanding how the body processes glucose, particularly in relation to insulin production and sensitivity. Impaired glucose tolerance can lead to conditions such as prediabetes and diabetes, making this an important field for studying and developing interventions to prevent and manage these conditions. Researchers may study factors such as diet, lifestyle, genetics, and medical conditions that influence glucose tolerance, as well as potential treatments and strategies to improve it.
