How It Works
CDC singleton total-gain ranges: BMI<18.5: 28–40 lb; 18.5–<25: 25–35 lb; 25–<30: 15–25 lb; BMI≥30: 11–20 lb.
Observed gain=current weight−pre-pregnancy weight. These are total-pregnancy ranges, not week-specific targets.
Scope and Limitations
- Singleton pregnancy only; not for multiple gestation or individual clinical treatment. Compare timing and personal needs with a prenatal clinician.
