Pregnant women sometimes experience episodes of low blood sugar, known as hypoglycemia. There are many signs, both mental and physical, of a hypoglycemic episode. All symptoms can be alleviated by eating, which puts sugar back into the body.
Shaking
When a pregnant woman is hungry, and her hands shake or tremble, it is possible that she is having a hypoglycemic reaction.
Light-headedness
A lack of sugar in the blood can affect the brain's function, leading a pregnant woman to become confused, dizzy or light-headed.
Anxiety
Mood changes can occur as a result of low blood sugar. A pregnant woman might experience anxiety, nervousness or irritability when her blood sugar is low.
Fatigue
Low energy levels are also a result of hypoglycemia. Sugar is the body's energy, so when a woman experiences low blood sugar during pregnancy, she may feel tired or weak.
