"What causes it?
Fainting is usually a result of a combination of factors, all of which are more likely to occur during pregnancy. Low blood pressure, low blood sugar, and surging levels of pregnancy hormones, which make blood flow away from the head, are all common contributors to fainting during pregnancy.
Tips?
If you feel dizzy or lightheaded, it’s a good idea not to get up too quickly, as this could bring on a fainting spell. Staying properly hydrated and maintaining a healthy, high-energy diet can help prevent fainting. If fainting is a problem for you, it’s important to avoid putting yourself in situations where fainting could result in physical harm. If you are feeling dizzy, you may want to have someone bring you a snack, and if you are prone to dizzy spells, it's probably a good idea to keep water and snacks nearby at all times. If you do faint, it's probably a good idea to let your healthcare provider know."
