At A Glance


Rapid lung development

Rapid development of baby's lungs in preparation for birth. The blood vessels in your baby's heart are also developing, but it will be several weeks before the entire heart is fully developed.

Your baby can move their muscles

At the 23rd week of pregnancy, your baby can already move the muscles of their whole body, becoming stronger and stronger, moving freely in the uterus, no longer just twitching unconsciously.

Baby Development at 23 Weeks

lung development

Rapid lung development

The blood vessels in the baby's lungs are developing, practicing the breathing manoeuvre that moves amniotic fluid in and out of the lungs. Surfactant, a substance made up of proteins and fats begins to form in the baby's lungs. This keeps the lungs inflated and prevents them from collapsing

sudatory system matures

Well-developed hearing

Your baby's hearing is getting better and better, and they will respond to sudden loud noises, such as a dog barking, a door closing, or a car engine.

Bones are beginning to harden

Bone hardening

Your baby's bones are also starting to harden, so remember to take in enough calcium every day!

Digestive tips

Although they cannot eat yet, their digestive system has started to practice pushing food, just like practicing swallowing, so the baby will be able to drink milk as soon as he is born. 

Your Pregnancy Symptoms at Week 23

Center of gravity changes, movements may become harder

As your baby grows rapidly and the hormones make the joints and ligaments loose, the pregnant woman's belly becomes bigger, making it difficult to see things at her feet. Your movements may appear clumsy, and you may experience leg edema and cramps. Remember to slow down the pace of daily life and be careful to avoid tripping accidentally.

Sweating and odor

Your body temperature is higher than usual, coupled with changes in metabolic rate and hormonal surges, causing you to sweat more than usual and have a more obvious odour, especially in the less ventilated areas such as armpits. This can be mitigated through simple good hygiene habits. 

Heartburn or indigestion

The body produces a lot of estrogen during pregnancy, which relaxes the lower esophageal sphincter, causing acid reflux, resulting in a burning sensation in the chest, which can lead to indigestion.


Headaches due to hormonal changes are very common. Stress and exhaustion can also make headaches worse. You should try to avoid overheating or dehydration. If you experience headaches, try lying in a dark and quiet room to rest or eating a snack.

Advice from OT&P Obstetricians

At the 23rd week of pregnancy, the belly has increased significantly, and there may be symptoms such as increased appetite and sweating. It is recommended that you:

  • Do pregnancy appropriate stretching and exercises or exercises to keep healthy and flexible. Speak to a women’s health physiotherapist for advice
  • If your blood pressure is high, it is recommended to receive a pregnancy toxaemia test. Severe pregnancy toxaemia will reduce the blood flow to the placenta.
  • Remember not to miss your monthly prenatal check-up
  • Choose loose, airy clothing to keep your body clean and dry
  • Do not squeeze the nipple deliberately, if there is milk, it should be cleaned with water

Tips for 23 Weeks Pregnant

  • Drink 2L of water per day to keep the body hydrated and prevent oedema
  • Increase your fibre intake with healthy foods such as vegetables, fruits and some grains. Burdock, sweet potato leaves, oats and bananas are all good. You can also eat cheese to increase the good bacteria in the gastrointestinal tract and help prevent constipation
  • Slow down the pace of life, especially when first waking up, to avoid tripping and injury
  • Avoid high-sugar diets and use fluoride toothpaste to clean your teeth
