Low blood sugar can result in weakness, confusion, headache, irritability, excessive hunger, excessive sweating or fatigue.

The normal range of blood sugar is 80 - 120 mg/dL (milligrams per deciliter) in the morning (after fasting for at least 8 hours). Normally, if the level drops below 70 mg/dL, the person is said to suffer from hypoglycemia or low blood sugar levels.

You may experience trembling and if your blood sugar still drops down, you could have a seizure. Increasing glucose intake, like drinking fruit juice, can help raise your blood glucose.

The ideal blood glucose levels range for you may be different from another person's and the level of glucose in blood would keep on changing throughout the day.

Similarly, the point at which the severe effects of insufficient blood sugar would be experienced may vary from person to person.
For some, sugar level below 70 mg/dL can be hypoglycemic, while for others the 'trigger point' can be at 60 mg/dL.

So, you need to consult your doctor about how much of blood sugar should be running, to keep you safe. He will tell you what blood sugar range is normal for you.

Lows are extremely dangerous, people who continue to go low often quit getting the warning signs. That is right your system will quit warning you until you like a light switch go into seizures and coma. One of my best friends has experienced this two times because he quit getting warnings. Had his wife not found him this last time when she did he would be dead. They sent him to a large hospital by lifeflight because the local hospital didn't have the specialists needed to save his life. It takes a few months of regular blood glucose numbers to reset your warning system if you have caused it to lower or go away totaly. Yes some people feel it at different times because they have lowered their body thermostat warning system lower by continually going to low. This information come from a book written by a diabetes specialists name Dr Bernstein ( Diabetes Solution ).
Just be very careful, don't play roulette with low blood glucose it can be as deadly as a gun.

My lowest low was 29, a couple months ago, while I was asleep. I only woke up because I had to go to the bathroom, and I figured I should check my blood sugar because I was pretty dizzy. Last night, I had a low of 39. I almost never feel lows until I'm in the 50's or 40's. My doc is concerned about nighttime hypoglycemia because my A1Cs are always lower than what they should be, considering my highs. I've only been diagnosed with type 1 for 2 1/2 years, but I stopped feeling symptoms of highs and lows around 6 months in, so at this point I'm fundraising for a diabetic alert dog.

You are so lucky to have woken up. I'm up right now scared to sleep. I have hard candy and juice right next to me. I've been diabetic for 11 years now. I had a low of 58 today. My husband noticed I looked drowsy. Luckily he is able to tell just by looking at me but I've lose the symptoms I used to get. I don't get shaky or extremely hungry anymore. I probably would have collapsed if my husband hadn't had me check my glucose level. Take care

I remember my husband telling me it was 29 before he rushed me to the hospital last July. I'd known I was low and had tried to correct it but couldn't get it back up fast enough. Those scary lows were one of the reasons for changing to an insulin pump. While on the pump, I've been in the 50's (usually because I overestimated the carbs I was eating) but I haven't experienced any hypos where I wasn't able to handle it myself. I guess, for me, the answer is no lower than 50. (And luckily I don't frequently get that low!)

Deana,I am good at letting my blood sugars go to low.You should see your doctor or find another that you are comfortable with because everyones body reacts differently .When my husbands goes below 80 he feels weak,tired and gets shakes.I on the other hand have been down to 39 and that was after 3 pc.of hard candy.I don't want to think about how low it was before I tested.My doctor recommended I keep some hard candy on my night table.
Another good thing to know is milk will get your B.S. up too.a 4oz. serving of juice(orange or grape is especially sweet) . Milk and and graham crackers work to.I was told to eat protein both to help me heal and to keep my B.S. up during the night. I am sure you know that proteins include things like milk,cheese,peanut butter,nuts eggs and not just meats.I like to have cottage cheese and pineapple as a late evening snack,I like to get grapes and cheese(I like colby jack )but you could use what you like.My husband likes those motzerella cheese sticks.I was told to eat every 2 1/2 hrs.just smaller portions.That is hard for me so I eat more often sometimes but not always. I hope this helps some.I have been diabetic for 23 + years now and I am at least 5 generation of diabetics.

my only recorded low was 40.

I really don't remember what alerted me to the low condition, it has been so long ago. I drank a whole can of regular orange soda warm to bring my BG up. Maybe a bit of overkill, but that was before I knew about DC. If I had other hypo events I was not aware of them.
