Most pregnant women experience shortness of breath. While some feel breathless right from the first trimester, some others experience it in the final trimester. If you are one among them, do not worry as the condition is completely normal and it will not harm you or your baby. Momjunction is here to tell you what causes breathlessness during pregnancy, under what circumstances it is not normal and when you should consult a doctor.

Is Shortness Of Breath During Pregnancy Normal?

It is common to experience shortness of breath especially in the third trimester and also in the early pregnancy. Nearly 75% of women who never felt breathless earlier feel short of breath during pregnancy (1).

If the breathlessness is due to some physical strain like climbing the stairs, then it is completely normal and harmless.

What Causes Shortness Of Breath In Pregnancy?

Breathing difficulties in pregnancy arise mainly due to the natural changes the body undergoes to adapt itself for holding a baby. This condition is also called Dyspnea or Dyspnoea (2). Here are a few trimester-wise body changes that could lead to breathlessness.

In The First Trimester:

  • The ribcage becomes broader to increase lung capacity. It moves upwards and outwards, thus making it difficult for you to get into tight-fitting tops.
  • Progesterone hormone is also responsible for your breathlessness. It makes your body absorb more oxygen into the bloodstream thus increasing the lung capacity. Your body will, therefore, get overwhelmed to breathe out excess levels of carbon dioxide.
  • Though your breathing rate is same as before your conception, you will take the breath more deeply, and this is the reason you will feel breathless (3).
  • Also, in the early pregnancy, the blood volume swells by about 50%, for which you heart has to work harder than before. This makes you breathe more even when you are resting.

In The Second Trimester:

  • The pregnancy hormones, as in the first trimester, allow your body to take more oxygen, therefore stimulating your brain to increase the number and depths of your breaths.
  • The hormones also cause swelling of the capillaries in the respiratory tract making you feel like you are breathing hard.

In the Third Trimester:

  • Your growing baby and expanding uterus push the diaphragm (the muscle that lies under the ribcage), restricting the amount of space for your lungs and making it hard for them to expand (4).
  • It will, therefore, make you to breathe faster, as if you have just run a marathon. It is quite normal and completely harmless to you and your fetus.
  • You will feel short of breath during the final trimester especially when you are carrying the fetus high or there is excess amniotic fluid.

You may also go out of breath when you take stairs, carry heavy weights or have gained weight unusually during pregnancy.

Shortness of breath can also happen when you are carrying twin or more babies. You need to take as much rest as you can.

Sometimes, breathlessness can indicate that something is wrong. The conditions include:

  • Anemia: If you are deficient in iron, you will have low red blood cell count(red blood cells carry oxygen from lungs to rest of the body and return carbon dioxide from the body to lungs) and your body works harder to provide oxygen for you and your baby. Breathlessness develops as one of the symptoms of anemia.

  • Asthma can be another reason for breathlessness (5), and you should check with your doctor if your breathing problem is due to this condition or pregnancy hormones.
  • If you have breathlessness along with heart burn, racing pulse, palpitations or cold fingers and toes, it could indicate a serious complication of heart or lungs. You should immediately check with your doctor.

Are upper back pain and shortness of breath common during pregnancy?

It’s quite common for expectant women to be short of breath. Breathing may become more difficult with time as enlarging uterus takes up more space, resulting in pressure against your diaphragm (the muscle below your lungs). This causes pain in the upper back and shoulders. The changes in your body, mainly because of your growing breasts, can also cause ache in the upper back.

How To Ease Shortness Of Breath During Pregnancy?

1. Practice Good Posture:

  • Good posture will relieve shortness of breath (6). While sitting, keep your chest lifted and your shoulder placed back. This gives enough room for your lungs to expand.
  • While sleeping, prop your body upwards using some pillows, to expand the space in your abdominal cavity, giving you relief.
  • Also, if you are lying by side, use an extra pillow to elevate your head.

2. Change Your Position:

If you feel breathless by being in the same position for long, shift your position to breathe easily. You may stand up straight as it will relieve pressure on your diaphragm.

3. Slow Down:

Listen to your body’s signals and rest whenever you feel like relaxing. When you feel out of breath, try to relax. Just stop from what you are doing and take a few deep breaths until you start feeling better. Give a break of about 20 minutes and then resume your activity.

4. Practice Breathing Exercises:

Breathing exercises (7) will help increase your lung capacity and offer more chest breathing (as abdominal breathing is difficult due to expanding uterus). You can try this breathing exercise:

  • Inhale deeply while raising your arms upwards and sides.
  • Then exhale while bringing back your arms down on sides.
  • Raise your head while inhaling and lower while exhaling.
  • Take a longer breathe into your chest than your abdomen by placing your hands on the rib cage.
  • Push your ribs against the hands while you are inhaling deeply. Practice deep breathing so that you can switch to it whenever abdominal breathing becomes hard.

How Long Will Shortness Of Breath Last?

If you are a first-time mother, your baby drops down to your pelvis around 36 weeks. This is the time when your breathing issues last. If you were pregnant before, your baby will not fall until the end of your pregnancy (10).

After delivery, the progesterone hormone naturally comes down, relieving pressure on your diaphragm and uterus. But, it takes at least a couple of months for your breathing system to resume to normal.

Does Shortness Of Breath Hurt Your Baby?

As long as you do not suffer from any other worrying symptoms, feeling short of breath is common and will not harm your baby since he will get plenty of oxygen through the placenta. Your deep and efficient breathing will supply your fetus with oxygenated blood.
