What is High Blood Sugar or Hyperglycemia?

Your body gets glucose from the foods you eat. Insulin is a hormone made in your pancreas that moves glucose into your cells and it regulates the amount of glucose in your bloodstream. When the insulin hormone is not able to do its work properly or there is an obstruction in its work, then the sugar level increases.

Apart from this, when the pancreas is not able to make insulin as per the requirement, then the sugar starts accumulating in the blood instead of going into the cells and the blood sugar level increases. This is called Hyperglycemia.

Causes of High Blood Sugar

  • Due to diabetes– Those who have diabetes, there is a risk of high blood sugar level. It can occur in type 1, type 2 and even gestational diabetes (diabetes occurring in pregnancy).
  • Due to excessive stress- During stress, hormones called Adrenaline and Cortisol increase in the body. These hormones can interfere with the action of insulin, which can increase the blood sugar level. And cause many complications such as mood swings, depression, insomnia, high blood pressure, heart disease.
  • Having too many snacks in between meals- If you eat frequently or eat too much at one go and also take unhealthy snacks like junk food, fried, soda-rich drinks in between meals, then this can also increase your sugar level. Actually, they contain added sugar and carbohydrates and they can increase blood sugar rapidly.
  • Lack of physical exercise/activities- Due to not so much physically active, the sensitivity of insulin is affected and the blood sugar level can increase. Due to lack of exercise, a person’s body is not able to use insulin properly. In fact, lack of exercise can cause muscle cells to lose their sensitivity to insulin, which can lead to diabetes or increased blood sugar levels.
  • Not taking diabetes medicines properly- If you are diabetic and do not take your medicine at the right time or take more or less dose of medicine, then your blood glucose can also increase.
  • Taking steroids- Steroids can increase your blood sugar level in different ways. Due to this, more glucose is released from the liver. Muscle and fat cells stop absorbing glucose. Also, reduce the body’s sensitivity to insulin, which can increase blood sugar levels.
