High Blood Sugar – 13 Causes of Glucose Elevation

Blood sugar fluctuates all through the day. However, having persistently excessive blood glucose ranges can result in persistent well being points. Hyperglycemia, typically often known as excessive blood sugar, is a big downside for individuals with diabetes. Not taking the appropriate actions might lead to lengthy-time period metabolic well being impairment.

The physique wants sufficient vitality to outlive and carry out at its greatest. The physique’s inner methods require vitality to take care of life, even whereas resting. The solely supply of vitality for the human physique is meals. It accommodates carbohydrates, proteins, fat, and hint quantities of nutritional vitamins, minerals, and salts. The physique breaks down this advanced ingested meals into numerous less complicated elements. 

Carbohydrates make up a good portion of the food regimen. They break down into glucose (a kind of sugar) within the abdomen and the small intestines. The bloodstream then absorbs glucose from the physique. As a consequence, the phrases “blood sugar levels” and “blood glucose levels” are synonymous.

Glucose is the first vitality supply for nearly all physique elements. It is the one vitality supply for the mind and is thus extraordinarily essential for survival. Maintaining an optimum stage is crucial as all of the organs obtain glucose by means of blood. The regulation of the blood glucose stage depends on many interdependent processes involving a number of physique methods. When these processes operate harmoniously, the blood sugar ranges keep inside regular ranges. Certain inner or exterior elements, nonetheless, do disturb regular functioning resulting in instability of blood glucose ranges.

Blood Sugar Levels: Measurement and Normal Values

The greatest method to forestall hyperglycemia is by practising diabetes administration. In addition, early detection of the hyperglycemic situation will help in treating it earlier than it worsens. Several varieties of assessments to measure blood sugar ranges are:

Fasting Blood Glucose

Fasting blood glucose works by checking the blood glucose stage after 8 – 10 hours of fasting, ideally in a single day. The acceptable worth per the American Diabetes Association (ADA) is under 100 mg/dL. Also, ADA stratifies the topics in response to check outcomes.

  • Normal Range: <100 mg/dL
  • Prediabetes: 100 mg/dL to 125 mg/dL
  • Diabetes: >125 mg/dL

Post-Prandial Blood Glucose Test

Post-prandial blood glucose check measures blood glucose roughly 2 hours after a meal. 

  • Normal: Values lower than 140 ml/dL
  • Prediabetes: Values between 140 ml/dL – 200 mg/dL
  • Diabetes: Values greater than 200 mg/dL

Random Blood Sugar Test

Random blood sugar stage monitoring can measure blood sugar vary at any time all through the day.

  • Normal: Values lower than 140 ml/dL
  • Prediabetes: Values between 140 ml/dL – 200 mg/dL
  • Diabetes: Values greater than 200 mg/dL

(*13*)Oral Glucose Tolerance Test

This check entails the administration of a syrupy liquid after 8 hours of fasting. The liquid accommodates about 75 grams of glucose. Also, the blood glucose stage is measured 2 hours after administration of this liquid.

  • Normal: Values lower than 140 ml/dL
  • Prediabetes: Values between 140 ml/dL
  • Diabetes: Values greater than 200 mg/dL

Out of all these assessments, any two values over 200 mg/dL want medical consideration.

A1C Test

The A1C check reveals the common blood glucose ranges for the final three or six months. So, one other identify for the check is the Estimated Average Glucose (eAG) Level check. 

The marketing consultant doctor decides the frequency of A1C assessments. It can vary from 2 to six instances a yr. Results under 5.7% are regular. An A1C stage of 7% corresponds to an estimated common glucose (eAG) stage of 154 mg/dL. 

The categorisation of A1C outcomes consists of:

  • Normal: Below 5.7%
  • Prediabetes: 5.7% to six.4%
  • Diabetes: Above 6.5% 

13 Reasons that Raise Blood Glucose Levels

Excess Body Fat and Insulin Resistance

Research infers weight problems is a big trigger of excessive blood sugar. Excess physique fats influences the insulin taken up by physique tissues. It steadily results in a dysfunction known as insulin resistance.

In this dysfunction, the muscle tissues, liver, and fats tissue can’t utilise glucose from the blood. It occurs because of numerous causes like weight problems and immune response to insulin.

The pancreas retains on producing insulin in growing quantities. This excessive insulin focus both makes the physique insensitive or develops insulin resistance. Finally, the pancreas can’t meet growing insulin necessities and is in hyperglycemic situation.

According to a examine, about 25% of adults above 20 develop insulin resistance. In 10 to fifteen years of prevalence, it might probably result in sort 2 diabetes mellitus.

Hormonal Changes

Hormones kind the idea of glucose steadiness within the bloodstream. Therefore, elements like bodily ache and trauma, menopause or menstruation, stress, and sleep deprivation could cause hormonal imbalance, leading to hyperglycemia. 


Administration of sure medication like steroids, beta-blockers, some antipsychotics, and some antibiotics intervene with numerous chemical processes within the physique to trigger raised blood sugar.

Damage to Intestinal Microbes

Extensive use of antibiotics or resistant infections damages the important, wholesome microbes within the intestines. Research reveals a hyperlink between broken intestinal microbes and elevated blood glucose ranges. In addition, it reveals that glucose metabolism associated to sort 2 diabetes may result from harm to the intestinal microbes.

The intestinal microbes can improve the manufacturing of the incretin hormone, a intestine peptide that promotes insulin manufacturing. They additionally produce quick-chain fatty acids which can be key in controlling blood sugar.

Gut microorganisms have an anti-weight problems impact by modifying the fats tissue. It additionally aids in sustaining wholesome blood glucose ranges. There are a number of research supporting this phenomenon.


Genes play an enormous function in inflicting diabetes. Autoimmune ailments like diabetes, a mixture of genetics, way of life elements, and surroundings play a significant function.

The danger of growing diabetes will increase by particular variants of the HLA-DQA1, HLA-DQB1, and HLA-DRB1 genes. However, the precise causes of diabetes usually are not but recognized.

Processed Foods and Artificial Sweeteners

Diet impacts each particular person in another way. But there’s an observable development of sure meals susceptible to trigger diabetes. For instance, processed meals with extra sugar, fats, and synthetic sweeteners can spike blood sugar. Research highlights the function of synthetic sweetener sucralose in elevating serum glucose.


It was an outdated suggestion to maintain chewing on one thing to stabilise the degrees. Modern analysis, nonetheless, negates this norm. So as a substitute, an info replace advises simply two giant meals and strict fasting for about 12 hours. 

A examine confirmed that consuming two giant meals helped cut back blood glucose higher than six small meals (day by day). Having acceptable quantities at supper time is another piece of recommendation. Having a sense of 75 to 80% abdomen fullness is fascinating. Overeating, too, causes a blood sugar surge. 


Research states that the quantity of water you drink is inversely proportional to the chance of growing diabetes mellitus. One cause is that diminished water content material mechanically will increase blood sugar focus. But, a vasopressin mechanism can be in motion. 

Dehydration causes the discharge of the vasopressin hormone. It will make the kidneys retain extra water, and the liver secrete extra glucose. Having much less water in response to environmental circumstances is one doable trigger of hyperglycemia. 

Vitamin and Mineral Deficiencies

Studies counsel a deficiency in micronutrients like chromium, magnesium, or vitamin D contributes to excessive blood glucose. There have additionally been a number of experiments administering vitamin dietary supplements to individuals with diabetes. They have efficiently managed blood sugar in some circumstances.

Physical Inactivity

Muscles soak up about 70% of the glucose within the blood. Movement of the physique and bodily stress make muscle tissues work extra, resulting in elevated glucose consumption. It will ultimately decrease blood glucose ranges.

A examine means that bodily inactivity is intently associated to insulin resistance by way of at the very least 9 molecular mechanisms. Many different analysis papers level out a hyperlink between the 2. In addition, bodily inactivity reduces weight problems and thereby reduces diabetes and in addition the interplay between the 2 issues.


Stress might take any kind starting from despair and anger to hostility. Research states that not solely despair however stress in any kind can predispose to sort 2 diabetes mellitus. The mechanism is sort of easy, which incorporates the manufacturing of further glucose comprising the physique’s struggle-or-flight response.

Stress of any type is one major stimulus that triggers this mechanism. In addition, this mechanism releases the hormone cortisol, which reduces insulin sensitivity. As a consequence, it is going to attenuate insulin resistance and enhance blood sugar ranges. 

Poor Sleeping Patterns

Sleep deprivation results in a discount in insulin manufacturing. Extensive analysis into numerous mechanisms means that sleep deprivation will increase diabetes danger.

It is extra frequent amongst individuals working alternate evening shifts. Apart from these, some physiological and routine phenomena trigger frequent spikes, particularly in individuals with diabetes. These are:

  • Sunburn
  • Coffee
  • Skipping breakfast results in elevated blood sugar after having lunch and dinner.
  • Late within the day, there could be a rise within the blood sugar stage.
  • Dawn phenomenon: The hormone ranges rise early within the morning. In diabetics, this may increase blood sugar ranges.

Other Health Conditions

Certain ailments or sicknesses also can contribute to excessive blood sugar. It consists of Cushing’s illness, acromegaly, polycystic ovarian syndrome, hypothyroidism, gestational diabetes, pancreatic most cancers, cystic fibrosis, pancreatitis, and different circumstances. Surgery, trauma, and even the frequent chilly or flu might be different doable causes.
