When your blood sugar drops below that range, your body, in a sense, overreacts. Warning signs of low blood sugar include shaking, sweating, clumsy movements, confusion, headache, hunger, paleness and mood and behavior changes. Possible causes of low blood sugar include too much exercise, too much insulin, not enough food and not eating on time. Stress or illness, such as a cold or influenza, also may cause high blood sugar. Symptoms may include frequent urination, increased thirst and fatigue.
Diabetic ketoacidosis is another condition to be aware of.
It's caused by increased levels of ketones, a blood acid that results when your cells lack glucose and your body begins to break down fat for energy. Ketones, a byproduct of fat metabolism, can build up in your blood and become dangerous to your health and the baby's. Use of this site signifies your agreement to the terms of use .
