Day 168 baby development and maternal changes

A: After fasting for 8-12 hours, draw blood once first → drink 75g glucose water within 5 minutes → draw blood once at 1 hour and once at 2 hours after drinking, three draws in total lasting about 2-3 hours. During the gaps, rest quietly and move little; after the test you can eat something to refuel.

A: Diagnostic criteria (GDM is diagnosed if any is met or exceeded): fasting ≥5.1 mmol/L, 1-hour ≥10.0 mmol/L, 2-hour ≥8.5 mmol/L. If all three are below these, it’s normal. Once GDM is confirmed you adjust your diet under nutrition-department guidance and monitor blood sugar; most cases are well controlled through diet and exercise.

A: Yes, you need to fast (no eating for 8-12 hours the night before; a little plain water is fine). Eat normally for the 3 days before — don’t deliberately restrict food or binge on carbohydrates, or it may affect the result. Arrive at the hospital fasting that morning, and bring water and a small snack for after the test.

A: Don’t over-anxietise. Most GDM is well controlled through diet management guided by a nutrition department (split meals, control refined sugar, mix coarse and fine grains) plus moderate exercise and daily blood-sugar monitoring; a few need insulin under a doctor’s guidance. Good control greatly lowers the risks of a large baby and newborn hypoglycaemia.

A: Week 24 is considered the "viability" threshold; under active NICU care the survival rate varies greatly by region and hospital care level (different studies report anywhere from very low to above half), and each extra week clearly raises survival (for week 25 different studies report roughly a third to over two-thirds). Ask your hospital’s neonatology department to assess the specific outlook. Preterm babies still have high complication risks, so keeping the pregnancy to term is best for the baby — seek care promptly at any preterm-labour sign.

A: Blood volume rises in the second and third trimesters, so dilutional anaemia is common. Food first: red meat, animal liver (≤50g a week), spinach with vitamin C; if the prenatal visit confirms iron-deficiency anaemia, the doctor prescribes iron, and taking it separate from calcium, milk, strong tea and coffee improves absorption — don’t take large doses on your own.

A: The three measurements at 24 weeks: BPD (biparietal diameter) about 58.6mm, AC (abdominal circumference) about 194.3mm, and FL (femur length) about 41.7mm, reflecting head, abdomen and leg development. If the three are in step, growth is good; a single slight deviation isn’t necessarily abnormal — go by your obstetrician’s overall assessment.

A: For a standard BMI, about 0.4-0.5kg a week in the second trimester, with a cumulative gain of roughly 6-9kg by week 24 being common. Watch the overall trend — use a weight-gain calculator to manage by BMI — and discuss with the doctor if it’s too fast or too slow.

A: You can start making a list in batches from week 24 and buy slowly, basically having it ready before week 34. The bag sorts into three: mum’s supplies (maternity pads, nursing bra, toiletries), baby’s supplies (NB nappies, swaddle, going-home outfit), and documents (ID card, social-security card, prenatal records).

A: ACOG advises women without complications about 150 minutes of moderate-intensity exercise accumulated weekly (walking, prenatal yoga, swimming), split over 5 days at about 30 minutes a day. Avoid intense exercise and pressure on the abdomen; stop and seek care for pain or bleeding.

A: It’s recommended. The CDC and ACOG recommend that pregnant women receive the inactivated flu vaccine: pregnant women are at higher risk of severe flu, the vaccine protects mother and baby, and it is safe at every stage. During flu season (September to April) you can get vaccinated; tell them you’re pregnant.

A: If there’s no placenta praevia, bleeding, cervical insufficiency or threatened preterm labour, gentle sex is fine using positions that don’t press on the belly and with gentle movements. Pause if you feel unwell or the doctor advises against it; see a doctor for post-sex bleeding or pain.

A: Practise sleeping on your left side to increase uterine-placental blood flow, using a pregnancy pillow to support your lower back, belly and legs; you don’t need to stay that way all night — comfort and good sleep matter; avoid prolonged lying on your back and face-down on the belly.

A: When a cramp hits, flex the foot and massage the calf. Prevention: supplement calcium and magnesium, drink water, stretch before bed, wear support stockings, and avoid long standing or sitting. If cramps are frequent with weakness and numbness, check blood calcium, magnesium and electrolytes at a prenatal visit.

A: Avoid raw or undercooked meat, fish and eggs, high-mercury large fish, unpasteurised dairy, alcohol, caffeine over 200mg a day, and excess animal liver (excess vitamin A). If you have GDM, strictly control refined sugar and sugary drinks as well.

A: Eat smaller meals more often and chew slowly, sit or stand for 30 minutes after meals before lying down, avoid eating in the 2-3 hours before bed, and avoid spicy, greasy, overly sweet food and carbonated drinks. In serious cases, use a pregnancy-safe antacid under a doctor’s guidance.

A: This week movements are strong and forceful, with obvious active periods (after meals, at night). Start to notice your baby’s daily routine in preparation for formally counting movements after week 28; if one day movements clearly drop by more than half, seek care promptly.

A: Eat more coarse grains and vegetables for dietary fiber, drink 1.5-2L of water daily, walk after meals, and toilet on a regular schedule without squatting long. In serious cases consult a doctor about a pregnancy-safe laxative rather than buying a stimulant laxative yourself; iron supplements can worsen constipation — discuss an adjustment with your doctor.
