You at 27 weeks pregnant: healthy weight gain, stretch marks and digestion
Healthy weight in pregnancy
Healthy weight in pregnancy is part of overall health for you and your baby.
This is why your health professional might check your weight at pregnancy visits.
Your recommended weight gain for pregnancy will depend on your body mass index (BMI) before you became pregnant. But it’s important to talk with your doctor or midwife about the best amount of weight gain for you during pregnancy.
Healthy eating and regular physical activity during pregnancy can help you maintain a healthy weight.
Stretch marks
You might start to see marks on the skin of your breasts, tummy or thighs as your bump grows. These are called stretch marks. They might look brown, purple, red or pink, depending on your skin tone. They usually fade over time.
Digestive symptoms
Some women might also feel constipated or bloated.
