FAQ - Hyperglycemia
(Powered by Yahoo! Answers)


I recently found out I have hyperglycemia and bought a home glucose monitering kit. My levels are all over the place, though. The readings I got were 9.1, 7.4, 7.3, 6.8, 5.8, 7.6 mmol in that order. whats going on, whats causing these changes?
Could different glucose readings be caused by water retention, because the body soaks up water to cope with higher glucose levels?

the numbers you gave are fine for the mmol reading... it translates that blood sugar levels are between about 90 and 175. The 5.8 and 6.8 readings are within the "normal" range and shouldn't alarm you. the 7.3, 7.4, 7.6, and 9.1 are a bit high. The things you eat and the time of day will effect your readings. Drink only sugar free soda (diet) . . . stay away from a lot of juices, no sweets, when baking or in coffee use Splenda in place of sugar.... it really isn't all that bad!.... Eat carbs only 2-3 times a week, no fatty meats.. that kind of thing. Your doc should have a handout on meal plans and things to avoid...  (+ info)

What does hyperglycemia physiologically do to the body?

I am not looking for symptoms, I want to know what is going on inside the body while one has hyperglycemia.

I don't know why this question is in this section. Hyperglycemia is diabetes. It destroys nerves and blood vessels in the extremeties, damages kidneys, enhances chance of stroke and heart attacks. Ultimately resulting in the amputation of feet or legs and the requirement for dialysis.  (+ info)

Why does hyperglycemia make one feel hungry?

Hypoglycemia resulting in insulin deficiency/resistance does this as well, but the two conditions are polar opposites in terms of blood sugar. How can they both cause hunger?

Shouldn't hyperglycemia provide ample energy for the body's cells? I understand that the cells are surrounded by glucose, so why can't they access it? What mechanism is being triggered (in, I assume, the insulin-glucagon axis)?

Also, why does hyperglycemia cause mental fatigue? Doesn't the glucose supply fuel the brain?

Just because there's glucose in the blood, doesn't necessarily mean it's getting to where it needs to go. Look up insulin resistance and/or hyperinsulinemia, or read this:

Is it worth it to get a home blood sugar monitor if you have hypo/hyperglycemia?

I have a mild case of hypo/hyperglycemia (hyper at night hypo in the morning) and was wondering if it was worth it to get a blood sugar monitor so i can track it and know when i should be worrying about weather i need to eat something before i don't feel good. just to use in the morning and at night. that way i don't feel sick as often. please answer if you have any opinion about it.

If you have a long standing diabetes, where sugar level fluctuates too much, there is no alternative for a glucometer. Glucometer will give an instant answer to your questions.
If you are persistently having hyper at night and hypo at morning you need to increase the morning dose and reduce the night dose. (This is because the morning dose will control the pre-dinner sugar level and the night dose will control the morning sugar level). I will suggest, you first control your morning sugar level and then try to control your night one.
Always check for the pre-meal sugar level, because if you try to control your post-meal sugar level you can be sure to have hypo afterwards. So don't try to control that unless that is too high.
Wish you best of luck.  (+ info)

What are hyperglycemia and hypoglycemia's effects on heart rate and blood pressure?

Basically, does hyperglycemia increase/decrease heart rate? Blood pressure? And does hypoglycemia increase/decrease heart rate? Blood pressure?

Cardiac arrhythmia may be associated with acute or chronic hyperglycemia. Secondary hypertension may also be due to diabetes.(chronic hyperglycemia)
The classic hyperglycaemic triad are:-
* Polyphagia - frequent hunger, especially pronounced hunger
* Polydipsia - frequent thirst, especially excessive thirst
* Polyuria - frequent urination, especially excessive urination
Hypoglycemia occurs when:
* Your body's sugar (glucose) is used up too quickly
* Glucose is released into the bloodstream too slowly
* Too much insulin is released into the bloodstream
Hypoglycemia can cause rapid heart rate and pounding heartbeat (heartbeat sensations). Home monitoring of blood glucose levels will show readings lower than 50 mg/dL.  (+ info)

Can you have hyperglycemia without having diabetes?

I went to an internal medicine doctor, who found out that I am slightly anemic and I have hyperglycemia (borderline). I don't know what the borderline thing means. My paternal grandfather had type I diabetes, most other women and men in the upper ages 50 and over have type II diabetes. I am always thirsty (even at night when i'm asleep), urination, I get really really really irritated if I haven't eaten anything and I feel extremely weak and tired if I haven't eaten.
Now, from what I read, you have to have diabetes to have hyperglycemia. But I don't. I've never been in a diabetic coma or anything. Should I go back to a doctor? No insurance right now, so I'm trying to think about everything b4 I walk in there ya know.
Yeah, it's interesting, I also have a minor heart murmur that can only be heard lying down, which could be a symptom of HYPOglycemia, but most of my personal symptoms are more like HYPERglyc. It's strange. I haven't been to that doctor since 2001 or so, and that was in another state. I used to pass out a lot when I was younger, and blackout, hasn't much happened lately, but sometimes I feel close to it. I don't know, something is for sure wrong. It kinda feels like when you drink too many pepsi's or something, it's a funny feeling, like I can almost feel sugar but I have nothing to go on so I feel weak. I don't know. I tried to change my eating habits (vegetarian) but I was getting weaker more often. So I don't know whats going on.

yes, i was reactive hypo- glycemic, and was told i didn't have diabetes, but needed to lose weight, because diabetes would be the next step.

(hypo= low blood sugar, hyper= high blood sugar) from your symptoms, are you sure it's not hypo, instead of hyper??

yes, you should go to a dr. and get on a good diet, avoid carbs, and eat more protien, fruits & veggie, a diabetic diet would suit you very well. that's what i did.
good luck.  (+ info)

does hyperglycemia include polyphagia as one of the symptoms or lack of appetite?

I am confused with hyperglycemia vs. hypoglycemia symptoms and some sources say one thing, some say something else, but basically I need to know if either of conditions includes lack of appetite or both have polyphagia?

Both hyperglycaemia [hyperglycemia] and hypoglycaemia [hypoglycemia] have polyphagia as a symptom.

In the case of hyperglycaemia, the glucose that's present in the bloodstream can't get into the body's cells for the creation of energy. (In type 1 diabetes this is because there's either no insulin being produced, or very limited quantities. In type 2 diabetes, the body's cells are resistant to the effects of the insulin that is still being produced.) Because of this, the body believes it is starving, causing the polyphagia.

In the case of hypoglycaemia, the blood glucose (sugar) level has fallen very low. Instinctively, the body wants you to eat, and thereby increase the blood sugar level. Again, polyphagia is the result ... at least, until blood sugar levels are back to 'normal'.  (+ info)

Why is it that a sugary drink will not harm a person having a hyperglycemia diabetic emergency?

Recently I took a St John Ambulance course and it said that if you come across someone in a diabetic emergency and if your not sure what type of diabetes they have that you should call an ambulance then give them a sugary drink, because the drink will help someone who has hypoglycemia and wont harm someone who has hyperglycemia, A friend asked me how it could not harm someone already suffering from high blood sugar and I couldn't answer...can anyone help me out here? thank you

Another way to look at it is by ratio.

Say the drink will cause a 30 point rise in blood sugar.

If someone with hypoglycemia has a level at 50, you give them the drink, that's a 60% increase in blood sugar (big increase - and 80 points will keep them alive).

Someone with hyperglycemia of 600 given the same drink only goes to 630, which is 5% (so not much of an increase at all and won't make anything worse).

insulin has the same ration kind of effect, but it's negative. Using the same 30 points for example, 50 drops to 20. 600 only drops to 570.

Always assume it's a low sugar level. Always. If it isn't, you haven't done any real harm. If you guess wrong and give insulin without knowing for absolute certain, you will.  (+ info)

What the difference between hypoglycemia and hyperglycemia?

Hypoglycemia has to do with low blood sugar, hyperglycemia has to do with high blood sugar.  (+ info)

What's the difference between hyperglycemia and diabetes?

one of my friends has diabetes....the other is hyperglycemic... and they were trying to explain to me that they're the opposite of each other but i don't get it. help??

Hyperglycemia, or high blood glucose, happens when there is too much sugar in the blood.
Causes of hyperglycemia
* Skipping or forgetting your insulin or oral glucose-lowering medication
* Eating the wrong foods
* Eating too much food
* Infection
* Illness
* Increased stress
* Decreased activity

Diabetes is a disease in which blood glucose levels are above normal. Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. When you have diabetes, your body either doesn't make enough insulin or can't use its own insulin as well as it should. This causes sugar to build up in your blood.

Diabetes can cause serious health complications including heart disease, blindness, kidney failure, and lower-extremity amputations. Diabetes is the sixth leading cause of death in the United States.

Interesting.. they look the same to me - are you sure they weren't talking about HYPO-glycemic??  (+ info)
