I bought a glucose monitor because diabetes runs in the family and wanted to keep myself in check. I have gotten both high and low readings but not sure what it could be. I’ve gotten readings so far of 58, 69, 130, 132, 136. The high numbers were taken 2-4 hours after eating and I noticed I got shaky and dizzy and my breathing increased rapidly whenever I got them. As for the low numbers, the 58 was taken after I had eaten in the morning, and the 69 was a fasting test. What do you think this is? Should I keep monitoring myself or is just a waste of time and money since strips can be expensive?

Angel asked:


I have seizures from a head injury. they got Bad this last june without warning. some have happened to happen after eating recently. Today I had a tester handy and tested at 137 and began to have seizures. ive been testing at 90 to just over 100 this week. I also hadnt eatin anything other then some chicken nuggets and didnt even want to eat that. Im always thersty and always having to pee even tho I Deny my self water due to the excessive urination Id never get any sleep.

I used a tester several years ago when I was having black outs directly related to sugar. I was testing then in the 50 to simply LO range. I do control my diet ever since then. The issue went away for the most part until now.

137 shouldnt cause me to seize-but it is.

I dated a diabetic once who liked to drink and do stupid s… So I learned real quick how to use the tester, insalin on him, and glucose tabs. So Im no idiot. I use a brand new one touch tester i program to every new set of strips.

so what are ideas here? Im thinking for Me thats High because of the seizures frequently happening after eating Anything now-and im not a junk food person or candy person.

ugh asked:


Let me try to explain what is happening to me. I keep getting hypoglycemia even thought I’m not diabetic.

It happens 2 ways, one…sometimes despite eating a 500 calorie balanced non sugary meal within the hour of working out, I get hypo during my routine daily 30 minute cardio workout. I have had some success in countering this by eating a banana 10 mins before I begin working out, but still I feel it’s not normal I have to do this.

The other way is at some point a couple hours after a meal I will start feeling lightheaded/weird and get a pounding heart and very anxious…this is the other way I get it. Then it seems even if I eat my sugar only stays up briefly as I’ve checked serially with many glucose test strips, I have never seen my sugar rise above 115 or so unless I drink a TON of soda or something like that, and even then it’s back down in the 80’s really quick. Again I used a box of nearly 50 test strips in a day to watch just what was going on at 15 minute intervals.

At the doctor I’ve had metabolic panels, a CT scan of my abdomen to look at my pancreas… nothing is seen. Any ideas?
1 thing to point out is that with over night fasts, I am never hypoglycemic, it’s almost always in the 80’s when I wake up
sorry but these answers are stupid so far, anyone else?

Leighlia asked:


I had gestational diabetes with both my kids. The youngest is now four. I’ve been good since the birth of the kids but here lately I’ve felt….well…off. I’m easily irritable, my concentration is seriously lacking at times, though I’m not overly thirsty, nor am I peeing more than I ever have. This morning for breakfast I had raisin bran (6:30am). At 11am I was feeling shakey and nervous. A fruit cup helped with the feeling and I continued my day as normal but with that nagging thought in the back of my head. I’ve had boughts of this “shaky” symptomatic feelings off and on the last year or so, feeling “Low”. So tonight after I ate dinner (2 bratwurst with buns, a little ketchup and onions, and about 5 ounces of coca-cola. Yes, I know the coke is bad).

I had my husband search for my old Accu-Chek Compact meter during the day since I was at work and thirty minutes after eating I took a reading. It read 308.

So my questions are this:

1) Do meter test strips (in a sealed drum) have a shelf life? (mine are now 4 years old.)
2) If so how would that affect the reading? Other than being way off.
3) If I’m really over 300, shouldn’t I feel all bad or something? I feel fine.

Any suggestions will help. I’ve started a meal diary and will be taking glucose levels with the strips I’ve got on hand for this week to have info to take in to the doctor when I go.

Just-Me asked:


1.A dialysis membrane separates two different sucrose solutions (sucrose dissolved in water):

* Solution A contains a 30% sucrose solution.
* Solution B contains a 15% sucrose solution.

Which of the following best predicts the movement of water molecules through the membrane?

A.)Water molecules will move equally from Solution A into Solution B and from Solution B into Solution A.
B.)Water molecules will not pass through the membrane.
C.)Water molecules will move in both directions through the membrane, but more water molecules will move from Solution A into Solution B than from Solution B into Solution A.
D.)Water molecules will move in both directions through the membrane, but more water molecules will move from Solution B into Solution A than from Solution A into Solution B.

2.If you wanted water to experience a net flow out of a dialysis bag filled with a 50% solution of sucrose, what would the minimum concentration of the beaker solution need to be?

A.The beaker solution concentration would have to be greater than 50%.
B.The beaker solution concentration would have to be 50%.
C.The beaker solution concentration wouldn’t really matter, since water can flow freely into and out of the bag.
D.The beaker solution concentration wouldn’t really matter, since sucrose cannot move out of the bag.

3.A dialysis membrane separates two different solutions:

* Solution A contains glucose dissolved in water.
* Solution B contains starch dissolved in water.

The molecular weight of the starch molecules is greater than that of the glucose molecules. Which of the following is most likely to occur?

A.Both sugar molecules and starch molecules will pass through the membrane, but water molecules will not.
B.Both starch molecules and water molecules will pass through the membrane, but glucose molecules will not.
C.Only sugar molecules will pass through the membrane; neither starch molecules nor water molecules will pass through the membrane.
D.Both sugar molecules and water molecules will pass through the membrane, but starch molecules will not.

4.Two potato strips were cut from the same potato. Each strip was placed in a salt water solution. Strip A was placed in a solution containing 20% salt; Strip B was placed in a solution containing 40% salt. How would the two strips be expected to compare in volume at the end of one hour in the respective salt solutions?

A.Strip A should have a greater volume then Strip B.
B.The volumes of the two strips should be equal.
C.Strip B should have a greater volume then Strip A.

i’m doing my science fair project on measuring the glucose concentration in a type of drink. i’m using a glucose test strip but i don’t know how to use it. please tell and do i need a “meter” - whatever it is- to use with the test strips. thank you so much for answering.
