You could start to experience worse symptoms when your blood sugar drops below 70 mg/dL. If you’ve had diabetes for a number of years, you might not always get or notice symptoms of slightly low blood sugar. Very young children might not be able to recognize or understand low blood sugar symptoms. Other children can, not all the time. To be totally safe, parents should do home blood sugar tests whenever they think their child has low blood sugar.
Symptoms of mild low blood sugar include sweating, nervousness, trembling, shakiness, weakness, strong hunger pangs, and mild nausea, headache and dizziness, blurred vision, a feeling of anxiety, and a rapid heartbeat. These symptoms might disappear after you have something with sugar in it, like orange juice or a candy bar. Symptoms of moderate or severe low blood sugar can be much worse, including unsteadiness, slurred speech, personality changes, and even loss of consciousness.
1. Sweating
You’ll almost always feel sweaty if your blood sugar drops too low and too suddenly. Have you ever gotten that clammy feeling on your hands and the back of your neck when you’re about to have a panic attack? That’s the kind of sweating you’ll have. Be sure to check the back of your neck and your hairline for sweat. It’s almost always there. Sweating, low blood sugar, and panic attacks are also connected. If your blood sugar drops too low, and you feel you’re about to faint, you could have a panic attack.
Clammy hands, neck sweating, and a general feeling of queasiness or uneasiness are often seen together. The sweating seen in low blood sugar is under the control of the autonomic nervous system, which is the part of the CNS that has control over the skin, among other parts of the body – and is often one of the first signs of low blood sugar. The excessive sweating comes on without any warning at all. It isn’t related to exercise or anything else you’ve been doing. And, it occurs no matter how cold or hot it is in the room.
