Your regular eating habits change when you become pregnant and probably sooner than you may think. You could already feel fatigued and queasy by the time you receive a positive pregnancy test (via Parents). Yet, even if you don’t notice any pregnancy symptoms right away, there is much going on behind the scenes. Since your body is busy creating a human, as well as a placenta and a much larger blood supply, you’ll require a steady level of blood sugar to stay balanced.
In addition, your baby is continuously using the available blood sugar in your body (as noted by Healthline). So if you’re not eating or you’re missing meals, it’s more likely your blood sugar will dip.
If you skip breakfast, or wait too long to eat between meals, you may get signs of low blood sugar. These include feeling dizzy or light-headed, cranky, headachy, fatigued, and weak (via Mayo Clinic). In order to prevent this, it’s important to take the time to eat regularly throughout the day.
