Blood Sugar Level.
Blood sugar levels outside the normal range may be an indicator of a medical condition. If the blood sugar level stays high, the condition is referred to as hypErglycemia; If the blood sugar level are low, the condition is referred to as hypOglycemia.
A temporarily elevated blood sugar level may also result from severe stress, surgery and other major illnesses. Intake of excess food and/or drinks, causes a surge in blood sugar. Also, certain drugs can increase or decrease blood sugar levels. Without medical conditions blood sugars return to acceptable levels.
Normal value of blood sugar ranges may vary slightly among different laboratories. Many personal factors affect a person's blood sugar level. A body's normal controls, when operating normally, restore the blood sugar level to a narrow range. The laboratory where someone’s blood sugar is drawn will provide acceptable levels for high, normal and low blood sugar.
Despite widely varying intervals between meals or the occasional consumption of meals with a substantial sugar load, human blood sugar levels tend to remain within the normal range. However, shortly after eating, the blood sugar level may rise, in non-diabetics, temporarily up to 7.8 mmol/L (140 mg/dL) or a bit more. The American Diabetes Association recommends a post-meal blood sugar level of less than 10 mmol/L (180 mg/dL) and a fasting blood sugar level of 5 to 7.2 mmol/L (90–130 mg/dL).
What can cause HIGH Blood Sugar?
Common causes of high blood sugar can include: Too much food, Too little exercise or physical activity, Stress, illness, infection, injury or surgery. These are just some of the many possible causes of high blood glucose or hyperglycemia.
What can cause LOW Blood Sugar?
Common causes of high blood sugar can include: Use of alcohol, Missed meals, Severe infection. These are just some of the many possible causes of low blood glucose or hypoglycemia.
Effects of Blood Sugar on Overall Health.
If blood sugar levels drop too low, a potentially fatal condition called hypoglycemia (low blood sugar) develops. c include tired, impaired thinking; irritability; shaking, twitching, weakness in arm and leg muscles; pale complexion; sweating; paranoid or aggressive mentality and loss of consciousness. Brain damage is even possible.
If blood sugar levels remain too high, appetite is suppressed over the short term. Ther may not be any symptoms of high blood sugar so it is worth being tested if there is a family history of high blood sugar. Extended periods of hyperglycemia (high blood sugar) causes many of the long-term health problems associated with diabetes, including heart disease, eye, kidney, and nerve damage.
Mechanisms that restore satisfactory blood sugar levels after low blood sugar must be quick and effective to prevent extremely serious consequences of low blood sugar: confusion or unsteadiness and, in the extreme, coma. It is far more dangerous to have too little sugar in the blood than too much, at least temporarily. In healthy individuals, blood sugar-regulating mechanisms are generally quite effective. Symptomatic low blood sugar is generally found only in diabetics using insulin or other pharmacological treatment. Low blood sugar episodes can vary greatly between persons and from time to time, both in severity and swiftness of onset. For severe cases, prompt medical assistance is essential, as damage to brain and other tissues and even death will result from sufficiently low blood-sugar levels.
What should you do in an emergency?
If mild or moderate hypoglycemia isn't treated right away, it can turn into severe hypoglycemia. People with severe hypoglycemia usually pass out. If you pass out, someone should call 911 right away. It is a good idea to teach your family, friends, and coworkers ahead of time about the symptoms of low blood sugar so they'll know what to do.
You should consult your doctor if you have any of the symptoms we have discussed above.
