14 Signs Showing That Your Blood Sugar Is Very High | May 17, 2025

The blood sugar level in the body indicates the amount of glucose in the blood, which is a type of sugar which is the main energy source for the body.

We consume glucose through food, and it is being distributed to all cells throughout the body.

High blood glucose(blood sugar), or technically, hyperglycemia, occurs when the body cannot use glucose properly( type2 diabetes), or it has insufficient amounts of it (type 1 diabetes).

If this condition lasts longer, for instance, for months and years, it will permanently damage certain body parts, including the kidneys, blood vessels, nerves, and eyes.

In diabetics, the blood sugar levels can be increased due to various different factors, including:

• over-treating an episode of hypoglycemia (low blood sugar)
• missing a dose or taking a wrong dose of the diabetes medication
• a lack of exercise
• stress
• an illness, like a common cold
• dehydration
• overeating, such as snacking between meals
• certain medicines, like steroid medication

Additionally, children and young adults may also experience occasional episodes of hyperglycemia during growth spurts.
