labor process

Previously, We have had a detailed discussion on Changes that happens in the body of pregnant women in the first trimester and second trimester. The third trimester of a woman’s pregnancy starts from week 29 to week 40, months seven, eight, and nine. Feelings at this stage of pregnancy tend to go from tiredness and worry to excitement about the baby coming into this world. Your baby continues to grow, and your changes in your body start to slow down. As the third trimester progresses, they’ll have a better chance of being born early, i.e., premature. 

Body Changes During Third Trimester

These are the following Top 10 changes that happen during the third trimester in the body of pregnant women :

Braxton Hicks Contractions

These are the pre-labor contractions that a woman goes through in the third trimester. Your cervix starts to get thin and soft in preparation for labor. Braxton hicks contractions are normal and happen to all pregnant women. When you start to get Braxton hicks, you might want to start packing your labor kit and be ready to go to the hospital for birth anytime soon.

Women can also face difficulty in sleeping. The overwhelming emotions of having a baby and other hormonal changes can cause issues with sleeping. Since taking a good amount of sleep is necessary for your and the baby’s health, it’s important to practice regular sleep habits. You might have to stay more active during the day, so you feel tired and eventually sleep at night without any difficulty.

Fatigue –

There is a subsequent increase in feeling more tired and weak. This happens due to low nutrient levels in your body. It would be best to have a healthy diet and rest more to avoid increased fatigue. You can always ask someone to do the chores and take mid-day naps to feel more active and less tired.

Stretch Marks

Stretch marks are normal. They tend to appear on your body during pregnancy since your skin stretches out as the baby grows. When the baby is finally born, your skin tends to go back to the initial stretch, thereby leaving stretch marks. Stretch marks can’t be avoided. Eventually, these turn into whitish and tan-colored lines, which aren’t visible after some time.

Dry Skin

Dry Skin As Skin Problem

This is one of the common Skin Problem Faced By Women During Pregnancy. Your skin may start to turn dry and itchy during the third trimester. The dry skin can be easily healed. You can always use oils and lotions to nourish the skin, so it doesn’t get drier. Glycerin is advised to reduce skin itchiness and dryness. If the itching is severe, you must contact your doctor and take proper medical assistance.

Heartburn In Third  Trimester

Tips To Prevent Or Control Heartburn:

  • Eating healthy food.
  • Having frequent meals.
  • Eating small portions at one time.
  • Eating now and then.
  • Avoiding fried food.
  • Spicy food increases heartburn.
  • Avoid taking junk foods.
  • Citrus fruits help to improve the taste.
