During pregnancy, the rapid rise of progesterone and estrogen levels affects the woman’s entire body, including the vocal cords (3) (4).

2. Increase in body fluids

Voice deepening or alternation can also be due to the increase in body fluids during pregnancy. Pregnancy increases blood volume by 45% and body fluids by three pounds (5) (6).

3. Edema or swelling of the vocal cords

Just like the other parts of the body, the vocal cords also swell during pregnancy. It causes heaviness in the vocal folds, altering the singing range. Pregnant women lose top notes but gain notes at the bottom. Do not strain your throat to reach the top notes. The blood vessels are extremely fragile during this time and may rupture if you strain to reach the top notes. It may also cause the vocal cords to tear.

4. Shift in voice range

During pregnancy, the blood vessels dilate across the whole body, including the vocal cords. Fragility of the vocal cord can also lead to change in voice.

5. Decrease in lung capacity

You may experience difficulty in breathing during pregnancy. It is because the growing baby in your womb pushes the diaphragm and every other organ upwards. It results in a decrease in lung capacity, endurance, vocal fatigue, and a decrease in phonation time (2).

6. Prone to LPR

During pregnancy, hormones lead to Laryngopharyngeal reflux (LPR). It results in the relaxation of the sphincter, which keeps the food in the stomach and prevents it from coming to the larynx. When the stomach capacity reduces, you are more likely to regurgitate acid. You may experience excessive throat clearing, postnasal drip, and altered voice (2).

7. Decrease In Nasal Resonance

During pregnancy there could be decrease in the nasal resonance, which may result in deep and husky voice (2).

8. Change In Posture

During pregnancy, there is a shift in the pelvis, back, and chest. It alters the entire support mechanism of a woman’s body, so much that she may not be able to sing in her last trimester (2).

  • If you notice a significant loss of voice during pregnancy.

Voice change during pregnancy is not uncommon and is seldom a reason for concern. The sudden shift in hormonal levels, vocal cord swelling, change in breathing patterns, and other medical reasons may lead to a change in your voice while pregnant. This change is more prevalent as you reach the last trimester. Moreover, your voice will return to normalcy in most cases soon after your baby’s birth. Nonetheless, it is important to consult a specialist if you have intense pain, detect sudden changes while speaking or singing, or have considerable voice loss during pregnancy.
