If a patient with type 1 diabetes mistakenly injects twice their prescribed insulin dose, which consequence follows?

💡 Explanation

A double dose of insulin triggers excessive glucose uptake by cells, primarily in muscle and adipose tissue, resulting in a rapid and severe drop in blood glucose levels, leading to hypoglycemia because of the increased glucose transport. Therefore, severe hypoglycemia occurs, rather than glycogen synthesis or immediate glucagon release, which are longer-term responses.

• Which mechanism explains why repeated drug use leads to decreased sensitivity in the mesolimbic reward circuit?
• If gene therapy successfully restores function to retinal pigment epithelium cells in a patient with age-related macular degeneration, which consequence follows regarding waste removal from photoreceptor cells?
• Why does craving intensify during drug withdrawal in addiction, overriding normal reward responses?
• A patient with a genetic defect has non-functional cytotoxic T-cells. Why does this immune deficiency increase the risk of virally-induced cancers more than bacterial infections?
• If sustained liver damage prompts hepatic stellate cell activation and extracellular matrix deposition during cirrhosis, which consequence follows?
• Why does chronic B12 deficiency lead to neurological damage in the dorsal columns of the spinal cord, rather than primarily affecting motor neurons?
