Feeling sleepy
Daytime napping and drowsiness are one of the clear indications of hypoglycemia. Sleepiness is one of the non-specific symptoms of hypoglycemia which causes daytime drowsiness, especially in older adults. The lower glucose levels in the blood lead the body to feel lethargic and sleepy almost all day long, and the feeling of sleepiness does not go away even after getting sound sleep at night.
