How might a high BMI affect my pregnancy?

Having a high BMI during pregnancy raises the risk of various health conditions, including:

• Loss of a pregnancy due to miscarriage or stillbirth. There's also a risk of repeated miscarriages.
• Diabetes during pregnancy, also called gestational diabetes.
• A condition called preeclampsia in which a pregnant person has high blood pressure. The pregnant person also may have signs of damage to the kidneys or other organs.
• Heart conditions.
• A serious condition called obstructive sleep apnea in which breathing stops and starts many times during sleep.
• The need for surgery called a C-section to deliver a baby. There's also a higher risk of health concerns linked to a C-section such as wound infections.
