Which risk increases for hibernating mammals during interbout arousal with disrupted vasodilation?

💡 Explanation

When vasodilation is disrupted during arousal from hibernation, peripheral tissues receive insufficient blood flow because blood viscosity is elevated at low temperatures, increasing risk of local hypoxia. Therefore tissue ischemia/necrosis risk increases specifically, rather than infection, depleted fat, or microbiome disruption, which relate to different physiological processes.
