How Is Hypoglycemia Diagnosed

Why do diabetics get low blood sugars at night?

The only way to know if you have hypoglycemia is to check your blood sugar with a blood glucose meter. Its a small machine that measures blood sugar. Most of these devices use a tiny prick of the finger to take a small amount of blood.

People with hypoglycemia unawareness may need a continuous glucose monitor. These wearable devices measure glucose every few minutes, day and night. An alarm sounds if blood sugar drops too low.

What Signs And Symptoms Do You Have If You Have Low Blood Sugar

Low blood sugar symptoms might strike without warning. They are as follows:

vision unclear due to light skin


unexplained weariness and unexpected nervousness


Inability to think properly or concentrate

loss of consciousness

seizure, or coma

Hypoglycemic unawareness occurs when a person is unaware that their blood sugar is decreasing. Your blood sugar may drop without you realizing it if you have this illness. You could pass out, have a seizure, or even slip into a coma if you dont get help very away.

Recognizing Hypoglycemia: Symptoms To Look For

Early symptoms of hypoglycemia include:

  • Shaking
  • Stubborn behavior
  • Extreme sleepiness

If your childs blood sugar levels stay low and continue to drop, symptoms will get worse. This can lead to seizures or unconsciousness if not treated immediately.

If seizures or unconsciousness occur or if your child cannot safely swallow do not give them anything by mouth. You need to give them Glucagon or Baqsimi right away.

How To Avoid Low Blood Sugar During The Night

Individuals with type 1 or type 2 diabetes experience low blood sugar while sleeping more often than they or their doctors may realize, according to a 2013 study reported in the Quality of Life Research journal. Fortunately, there are simple ways to prevent nighttime low blood sugar, or hypoglycemia.

Avoiding Nighttime Hypoglycemia: 8 Tips

1. Know the symptoms of hypoglycemia. Feeling anxious and/or having a rapid pulse before bedtime can indicate approaching hypoglycemia. When blood sugar drops below 70 mg/dl during the night, you may experience sweating, shakiness, headache, confusion and even nightmares. You can also wake up to a high glucose reading owed to your body compensating for the nighttime low.

2. Before turning in at night, check your blood sugar. A typical bedtime target is 140 mg/dl. If your glucose is low, a healthy snack in proportion to the drop in blood sugar will help if your blood sugar is slightly low, eat a small-sized snack. Pump users, consider a reduction in insulin dosing.

3. Avoid strenuous late-night exercise. Complete your exercise routine at least two hours before bedtime. Strenuous exercise before turning in can contribute to low overnight glucose levels. If you exercise late and your glucose is less than desirable at lights out, you may need to increase your bedtime snack.

6. Keep a remedy at hand. Keep juice or glucose tablets near your bed to quickly treat nighttime lows, especially if this is a recurring problem for you.

    How To Prevent Low Blood Sugars In The Future

    There is probably no way to completely eliminate low blood sugars at night, but I have learned how to limit them quite a bit. What I do is pretty simple I try to learn from my mistakes. If I have a low during the night, Ill go back and see how my bolus and basal patterns were the day before, what I ate, and what I did.

    For example, my last low blood sugar was at 4 am a few nights ago, and when I went back and analyzed the data, this is what I found:

    Since it was 4 am and my last snack was at 11 pm, the low couldnt be due to my last bolus. I also hadnt changed my basal amount. However, I had moved my workout to later in the evening. So my conclusion was that to limit future nighttime lows, I should take less basal insulin before I go to bed if I work out later in the evening. Thats a pretty easy fix. I reduced my nightly basal and now Im sleeping through the night again and waking up with perfect sugars.
