Since you usually get less sleep, please talk to your doctor about your sleep patterns. Poor quality sleep can affect many areas of your life and health, and your doctor may be able to help you if you have insomnia, another sleep disorder, or conditions affecting your sleep.
Symptoms can be different depending on how low your blood sugar level drops. 1  Mild hypoglycemia can make you feel hungry or like you want to vomit. 2  You could also feel jittery or nervous. 3  Your heart may beat fast. 4  You may sweat. 5  Or your skin might turn cold and clammy.
Low blood sugar (hypoglycemia) usually occurs while fasting. Signs and symptoms of reactive hypoglycemia may include hunger, weakness, shakiness, sleepiness, sweating, lightheadedness, anxiety and confusion. It's possible to have symptoms that are similar to reactive hypoglycemia without actually having low blood sugar. True reactive hypoglycemia symptoms that are caused by low blood sugar occurring after eating are uncommon.
