Why Are You Losing Weight While Breastfeeding?
There are several factors that may contribute to weight loss during breastfeeding.Your body burns more calories
Breast milk production requires extra energy. Therefore, your body naturally burns more calories, even while you are resting.
Your body uses stored fat
During pregnancy, your body stores extra fat to support breastfeeding later. As breastfeeding continues, these fat stores may gradually be used for milk production.
You may be eating less than you need
Looking after a newborn can make regular meals difficult.
You may:
- Skip meals
- Eat smaller portions
- Forget to snack
- Drink less water
You are more active than before
Caring for your baby involves frequent lifting, walking, feeding, and interrupted sleep. Although it may not feel like exercise, these daily activities increase your energy expenditure.
An underlying medical condition
If your doctor suspects that your weight loss is unrelated to breastfeeding, they may investigate other conditions, including:
- An overactive thyroid
- Poorly managed diabetes
- Long-term infections
- Digestive conditions that affect nutrient absorption
