임신 23주

23주 차에 아기는 키 약 29-30cm, 몸무게는 500-600g 정도가 됩니다. 이번 주 가장 기적적인 변화는 폐에서 일어납니다. 아기의 폐 속에 허파꽈리(폐포)가 형성되기 시작하고, 폐가 서로 달라붙지 않게 하여 호흡을 가능하게 돕는 계면활성제가 생성되기 시작합니다. 폐가 완전히 기능하려면 아직 시간이 더 필요하지만, 이 발달은 아기가 세상 밖에서 스스로 생존할 수 있는 확률을 매일 높여줍니다. 또한 아기의 피부는 여전히 쭈글쭈글하지만, 이번 주부터 피부색에 변화가 생깁니다. 모세혈관이 피부 표면과 가까워지면서 피부가 분홍빛을 띠게 됩니다. 아기의 췌장에서는 성장에 필수적인 호르몬인 인슐린을 분비하기 시작합니다. 감각 또한 전문가 수준으로 발달하여 외부 소음이나 갑작스러운 빛, 엄마의 목소리에 훨씬 더 뚜렷하게 반응합니다. 이제 단순히 발로 차는 것뿐만 아니라 몸 전체를 돌려 자세를 바꾸기도 합니다. 뱃속의 이 작은 가지는 매 순간 더 독립적인 생명체로 성장하고 있습니다.

23주가 되면 자궁이 배꼽 위로 약 3-4 cm 정도 올라옵니다. 이러한 성장은 체내 수분 균형에 영향을 주어, 특히 하루 일과가 끝날 무렵 발과 발목에 부종이 나타날 수 있습니다. 혈액량이 크게 증가하고 자궁이 골반 혈관을 압박하면서 혈액이 심장으로 돌아가는 흐름이 어려워지기 때문입니다. 신발이 꽉 끼거나 양말 자국이 선명하게 남는 것은 이 시기에 흔히 나타나는 증상입니다. 이번 주에는 브랙스턴 힉스(Braxton Hicks)라고 불리는 가진통을 경험할 수도 있습니다. 배가 갑자기 공처럼 딱딱해졌다가 몇 초 후에 다시 부드러워지는 것을 느낄 수 있습니다. 이는 실제 분만 진통이 아니라 자궁이 출산을 대비해 연습하는 과정입니다. 대개 통증이 없으며 자세를 바꾸거나 물을 마시면 사라집니다. 하지만 수축이 규칙적으로 변하거나 강해진다면 반드시 의사와 상담해야 합니다. 또한 자궁이 위를 압박해 생기는 속 쓰림(역류)과 흉곽이 확장되는 느낌도 이번 주의 신체적 변화 중 하나입니다. 몸이 점점 무거워지는 만큼 자신에게 더 많은 휴식 시간을 선물해 주세요.

During this time when your hands and feet start to swell, you should pay close attention to the amount of sodium in your diet. Salt causes the body to retain water and increases swelling. However, cutting out salt completely is not recommended; a small amount of high-quality salt is necessary for balanced iodine intake. The key is to stay away from hidden salts in packaged foods, pickles, and processed meats. The most effective way to reduce swelling is to drink more water. When your body is dehydrated, it tries to hold onto existing water in your cells, which leads to bloating. Drinking at least 3 liters of water a day helps your kidneys flush out sodium and cleanse your system. Additionally, potassium-rich foods help maintain fluid balance in the body. Your appetite might be very high this week; to manage sweet cravings, choose nuts containing magnesium or fruit yogurts. To prevent nighttime cramps, give your digestive system a break by avoiding heavy and spicy meals in the evening. Remember, the more fluids you consume, the lighter you will feel.

Week 23 marks the medical milestone of fetal viability, which can sometimes trigger fears of preterm labor for some expectant parents. Every little ache or Braxton Hicks contraction might lead you to wonder if labor is starting. This anxiety is simply your maternal instinct's way of trying to protect your baby, but try not to let these worries overwhelm your daily life. To support your mental well-being, try practicing mindfulness and reminding yourself of your body's strength. Learning the signs of preterm labor, such as regular contractions, water breaking, or bleeding, should not be frightening; instead, being informed can provide a greater sense of control. Share your fears with your partner so you do not have to manage this journey alone. Additionally, focusing on baby’s movements is a wonderful way to feel reassured of their health. Keeping your mind occupied and peaceful is a beautiful gift for both you and your baby.

You may have focused on aesthetics while preparing the nursery, but as of week 23, it is time to look at home safety from a broader perspective. Even though your baby won't crawl right away when they are born, taking safety precautions while you still have energy and before your bump gets too big will make things easier for you. Safety Checklist: Paint and Chemicals: Make sure the paints used in the nursery are water-based and VOC-free (volatile organic compounds). Securing Furniture: Get the necessary hardware now to anchor heavy furniture that could tip over, such as dressers and bookshelves, to the wall. Outlets and Corners: Make a list to buy outlet covers and protective pads for sharp table corners around the house. Safety Detectors: Check if you have smoke and carbon monoxide detectors in your home and test their batteries. When shopping, set aside a budget not just for clothes, but also for medical safety products like baby monitors, thermometers, and nasal aspirators. Being prepared will greatly reduce the chaos when a new member joins the family.

Don't be surprised if you hear your partner say, "You snored a bit last night," during week 23. Increased blood volume and estrogen levels cause the nasal lining to swell (pregnancy rhinitis). This can make breathing more difficult and lead to snoring. Additionally, as your belly grows, lying on your back can make it harder to breathe. Weekly Tip: Propping your head up with an extra pillow while you sleep helps keep your nasal passages more open. Using nasal strips can offer a safe, drug-free solution. Air out the room well before bed and use a humidifier to prevent the air from getting too dry. If your snoring is accompanied by gasping for breath or extreme daytime sleepiness, be sure to consult your doctor (this could be related to pregnancy-induced high blood pressure). Sleeping on your left side and placing a pillow between your legs not only increases blood flow to your baby but also helps you breathe more comfortably.
