Which risks are assessed?
Gestational diabetes, high blood pressure and pre-eclampsia, blood clots and birth complications are among the concerns. Attend antenatal appointments and recommended assessments regularly.
Weight management
Before pregnancy, you can plan to improve metabolic health. Do not start a weight-loss diet on your own during pregnancy. Nutrition, activity and weight changes should be managed with the maternity team.
Frequently asked questions
Is a healthy pregnancy possible with a high BMI?
Yes. Increased risk does not mean a complication will definitely occur.
Is a standard BMI calculator suitable during pregnancy?
Current pregnancy weight is not appropriate for standard BMI interpretation. Assessment depends on pre-pregnancy weight and pregnancy circumstances.
When can I become pregnant after bariatric surgery?
Discuss timing with the surgical and maternity teams after reviewing weight stability and nutrition. Avoid trying to conceive during rapid weight loss.
