Hi, during sport i often faint or get very lightheaded, my doctor thinks it may be due to a sudden drop in blood sugar levels. The other day my blood sugar levels dropped from 7.3 mmol/L to 4.4 mmol/L within 20 minutes of exercise. Is this bad or normal? How much should your blood sugar levels fall by when doing exercise?
Thanks in advance.

It is not guaranteed that glucose levels will fall during exercise. some people’s glucose will fall and some people’s will rise.

faintness and lightheadedness can also be caused by blood pressures changing.

Hi im 13 and my blood sugar is 185. Is that a normal for my age.
Today it went down to 130 i figured it really gets high and acts up when u eat sugar really. I am no longer worried.

To get a better and safer response to your questions explain when you took this measurement.

How soon after eating.
What was the last meal you ate. What you ate.

Remember you reading is a spot reading and could really be wild after eating several pancakes for breakfast.

Update your question accordingly.

Best Wishes.

I had a blood test done on my sugar and cholesterol at about 7 PM. My blood sugar was 113. I know under 100 is normal when fasting, which I obviously was not. The nurse said that 113 is fine because I was not fasting. Is that true? Does that mean that I am in normal range?

yes i have diabetes type 2 and my doctor told me that between 80 and 150 is normal

I am a prediabetic and I need to go to a clinic to check my fasting blood sugar. I am not sure whether 10 hours of absolute fasting (only water during this period) or 12 hours of absolute fasting will give an near accurate result. Experienced people please help.

A fasting blood test just means that you are not supposed to eat or drink eight to 12 hours before having blood taken. However, you can–and should–drink water. You should consult your doctor about whether your should avoid medications. The reason for fasting prior to a blood test is so that food and beverages do not influence your test ratings. Your doctor is trying to gauge specific information before any external substances create a false outcome.

I don’t know why, but I have never been a fan of sugar… I rarely eat chocolate, sweets, etc. But I notice, that sometimes, when I miss lunch, I become dizzy… Or, that I can not fall asleep without eating anything. But, I don’t see this problem in anyone else in my family.

If I have low blood sugar, is that why I have to eat right before I go to sleep? I don’t know… Thoughts?

what ur experiencing is a condition called ‘hypoglycemic’ which means ur body dont have enough sugar.
symptoms of hypo include
-dizziness
-hunger
-shaky hands
-lethargic
-blurred vision

I’ve had low blood sugar before but this feeling is different.
I’m on Metformin, not for diabetes though. I am trying to concieve and have PCOS.
I was feeling weird the other day and it went away about 45 minutes after I took my metformin. I’ve done that exact same things a couple more times. So it’s making me think I’m getting this feeling from high blood sugar.

Can’t concentrate and will feel moody. You may have muscle cramps and temporary blurred vision. You feel tired and thirsty and with a need to urinate often. You may also have a yeast infection. These are the common symptoms of high blood sugar.Metformin is an oral antidiabetic – non insulin dependent. In your case,having PCOS -Polycystic ovary disease or many cysts in the ovaries,the medication Metformin makes ovulation normal and that’s why you are taking the medication. I would like to add that in case you are overweight, losing weight may help you reduce insulin levels,stimulate ovulation and improve fertiity. Hope this help. Good luck!  Neida

What causes the frequent urination when blood sugar is high? I know it’s because high blood sugar dehydrates the body by making the body diurese fluids but why? Please explain it to me the best you can.

blood sugar is called glucose

glucose is negatively charged. water molecules always surround something that has a charge in order to neutralize the charge

when you have high glucose in the blood, its so much that it gets into the urine as well. the glucose in the urine draws water into the urine. Then you pee out the water. That is how water is lost from the body when you have high blood sugar

At my last physical, my doctor told me by blood sugar levels were just SLIGHTLY above the normal range.

Are there any foods that will actually lower blood sugar? I’m not asking for which foods to avoid, just if there are any foods that actually counteract high blood sugar.

ALL foods raise blood sugar, because ALL foods are burned for energy. Physical activity can help lower your blood sugar.

Im ill at the moment and my blood sugar shot down to 2.8. now im worried that il have to be admitted to hospital..does anyone know how low it will have to go before im admitted? and any good ideas on what to it to raise it up? thanks

Generally speaking, LOW blood sugar does not require hospitalization.

However, if this is CHRONIC (happens frequently) then hospitalization may be required "for observation" to determine the cause of the problem.

To raise you blood sugar — EAT! Eat a donut, a couple of piece of breads or some crackers, or some hard sweet candy.

YOUR blood sugar is probably low because you are not eating correctly due to your illness. FORCE YOURSELF to eat SOMETHING.

This is the meal I have after breaking fast(of almost 14 hours). Also, before breaking the fast, the blood sugar levels have been 76 and 79. Is that normal too?

yes. below 71 is too low and above 147 is too high.
