Weight loss in the third trimester can occur, but the context matters. Losing 1.5 kg over a few weeks while managing GDM through diet and regular walking is generally considered acceptable, especially if:
You're maintaining consistent energy levels and feeling well
Your baby's growth is tracking normally (confirmed by your OB-GYN)
You're eating adequate, balanced meals (not restricting calories)
Your walking routine is moderate, not excessive
However, here's what's important:
During pregnancy, especially with GDM, the focus should be on stable, consistent weight rather than active weight loss. Your body needs sufficient nutrition to support both your health and baby's development. A modest weight loss is different from intentional calorie restriction, which can be risky.
My recommendations:
Confirm with your OB-GYN — Share this weight loss at your next visit to rule out any underlying concerns
Review your meal frequency — Ensure you're eating 4-5 balanced meals daily (protein, complex carbs, healthy fats)
Track blood sugar levels — Continue monitoring to ensure GDM remains well-controlled
Hydration matters — Sometimes perceived weight loss is fluid fluctuation; stay well-hydrated
Continue safe movement — Walks are excellent; avoid high-intensity exercise without medical clearance
Red flags to watch for:
Persistent nausea or vomiting
Extreme fatigue
Dizziness or weakness
Reduced fetal movement
If you experience any of these, contact your doctor immediately.
You're doing brilliantly managing your GDM during pregnancy! Keep prioritizing balanced nutrition and regular check-ups. Every pregnancy is unique, so personalized guidance from your healthcare team is essential.
Wishing you a healthy remainder of your pregnancy! 💚
