This work describes methods to establish acute and chronic hyperglycemia models in zebrafish. The aim is to investigate the impact of hyperglycemia on physiological processes, such as constitutive and injury-induced neurogenesis. The work also highlights the use of zebrafish to follow radiolabeled molecules (here, [18F]-FDG) using PET/CT.

Hyperglycemia is an abnormally high blood glucose level. It is diagnosed by fasting glucose ≥126 mg/dL, 2-hour oral glucose tolerance test (or OGTT) ≥200 mg/dL, random glucose ≥200 mg/dL with symptoms, or HbA1c ≥6.5%. However, HbA1c results may be unreliable in certain conditions, such as anemia or hemoglobinopathies, and the diagnosis should be confirmed unless classic symptoms are present. Postprandial hyperglycemia is typically considered significant when glucose levels exceed 180 mg/dL two...

Asthma, a common chronic respiratory condition, is classified considering the frequency and severity of symptoms alongside lung function impairment. Understanding this classification is essential for appropriate treatment and management. Here's a detailed look at the classification of asthma and its clinical features and complications: Classification of Asthma Intermittent Asthma: Symptoms occur fewer than twice a week. Night-time awakenings due to asthma occur fewer than twice a month.
FAQs
When blood glucose rises beyond the kidney’s reabsorption capacity, glucose remains in the urine and draws water with it. This osmotic movement increases urine production rather than representing simply increased fluid intake. The resulting water loss helps explain why frequent urination is a particularly informative physiological sign of disrupted glucose regulation.
Increased thirst develops as the body responds to fluid lost through glucose-associated urination. This response encourages replacement of water, linking a subjective symptom with kidney handling of glucose and body-fluid balance. Considering thirst together with urinary frequency can help researchers interpret how altered blood glucose affects whole-body physiology.
Fatigue can arise when cells do not use glucose efficiently, even while glucose remains elevated in the blood. This connects the symptom to insulin action and cellular metabolism rather than to glucose concentration alone. In biology, that relationship helps researchers examine how endocrine regulation influences energy availability across tissues.
Blurred vision is associated with changes in lens hydration when blood glucose remains high. Because the lens depends on a stable fluid environment to maintain its optical properties, altered hydration can interfere with clear vision. This symptom provides a useful connection between systemic glucose imbalance and the physical function of a specialized sensory structure.
A pattern combining frequent urination, thirst, fatigue, or blurred vision can serve as a clue prompting earlier testing and continued monitoring. The value lies in the pattern’s connection to glucose regulation, insulin action, and cellular metabolism. Tracking these signs helps investigators and healthcare researchers relate observed changes to possible metabolic disorders.
These symptoms give observable evidence of processes occurring across several biological levels. Kidney water handling, cellular glucose use, lens hydration, endocrine control, and insulin action can be considered together rather than as isolated events. Studying those links supports investigation of diabetes and other metabolic disorders, including complications associated with sustained high blood glucose.
