29th Week of Pregnancy: A Comprehensive Guide
The 29th week of pregnancy marks the beginning of the third trimester, a period of significant growth and development for both the mother and the baby. During this week, the baby’s organs are maturing rapidly, and the mother’s body is preparing for labor and delivery.
Fetal Development
At 29 weeks, the baby weighs approximately 2.5 pounds (1.1 kilograms) and measures about 15 inches (38 centimeters) in length from crown to heel. The baby’s skin is still thin and wrinkled, but it is beginning to thicken and develop a layer of fat.
The baby’s lungs are also continuing to develop, and they are now capable of producing surfactant, a substance that helps the lungs expand and contract. The baby’s brain is also growing rapidly, and the baby is beginning to develop a sense of hearing.
Maternal Changes
During the 29th week of pregnancy, the mother’s body is undergoing a number of changes to prepare for labor and delivery. These changes include:
- Increased blood volume: The mother’s blood volume increases by about 50% during pregnancy. This is necessary to meet the increased oxygen and nutrient demands of the baby.
- Weight gain: The mother will typically gain about 1 pound (0.5 kilograms) per week during the third trimester. This weight gain is due to the growth of the baby, the placenta, and the amniotic fluid.
- Uterine enlargement: The uterus continues to enlarge as the baby grows. This can cause the mother to experience abdominal pain, back pain, and shortness of breath.
- Frequent urination: The mother may need to urinate more frequently as the uterus puts pressure on the bladder.
- Hemorrhoids: Hemorrhoids are swollen veins in the rectum. They are common during pregnancy due to the increased pressure on the veins in the pelvis.
- Varicose veins: Varicose veins are swollen, twisted veins that can occur in the legs or vulva during pregnancy. They are caused by the increased pressure on the veins in the pelvis.
- Constipation: Constipation is common during pregnancy due to the hormonal changes that slow down the digestive system.
- Heartburn: Heartburn is a burning sensation in the chest that can occur during pregnancy due to the relaxation of the esophageal sphincter.
- Insomnia: Insomnia is common during pregnancy due to the physical and emotional changes that the mother is experiencing.
