懷孕第 23 週

在第23周，您的宝宝身长约29-30厘米，体重约500-600克。本周最神奇的进展发生在肺部。宝宝肺部的肺泡开始形成，并且开始产生肺表面活性物质，这种物质可以防止肺部粘连，使呼吸成为可能。虽然肺部要达到完全运作还需要时间，但这一进展让宝宝在外界生存的机会与日俱增。 此外，虽然宝宝的皮肤仍然皱巴巴的，但本周肤色开始发生变化。毛细血管更接近皮肤表面，使皮肤呈现出粉红色。宝宝的胰腺开始产生胰岛素，这是生长发育至关重要的激素。他的感官现在已经非常敏锐，对外界的噪音、突然的光亮以及您的说话声会有更明显的反应。现在他不仅会踢腿，还会通过转动整个身体来尝试改变姿势。肚子里这个小茄子，每一秒都在向更独立的生命形式转变。

At week 23, your uterus has risen about 3-4 cm above your belly button. This growth affects your body's fluid balance, and you may notice swelling in your feet and ankles, especially at the end of the day. The massive increase in your blood volume and the pressure your uterus puts on pelvic veins make it harder for blood to return to your heart. Tight-fitting shoes or sock elastics leaving marks are common complaints this week. This week, you may also encounter practice contractions called Braxton Hicks. You might notice your belly suddenly tightening like a ball and relaxing after a few seconds. These are not labor pains; they are your uterus practicing for birth. They are usually painless and subside when you change positions or drink water. However, if these contractions become regular or intensify, you should definitely consult your doctor. Additionally, heartburn (reflux) caused by the uterus pressing on the stomach and a feeling of expansion in the rib cage are among this week's physical changes. As your body feels heavier, you should give it more time to rest.

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.
