From shortness of breath to heartburn…the effect of uterine expansion on the pregnant woman’s organs

Fetal pressure on the internal organs is one of the most disturbing symptoms during pregnancy, especially in the last months, as a result of the natural expansion of the uterus, which moves from a small size below the navel to approximately the level of the rib cage before birth. This expansion leads to a change in the positions of a number of vital organs within the body, which explains a group of common symptoms in pregnant women.

The effect of uterine growth on internal organs
• Stomach and intestines: The uterus pushes the stomach and intestines upward, which slows down the digestive process and increases the feeling of fullness, bloating, and heartburn, especially with the effect of the hormone progesterone, which relaxes the muscles of the digestive system.
• Bladder: Its functional volume decreases due to direct pressure, which causes frequent urination during the day and at night.
• Lungs and diaphragm: The elevation of the uterus reduces lung capacity, causing a feeling of shortness of breath, especially in the last third of pregnancy.
• Spine and muscles: The growth of the uterus changes the body’s center of gravity, which increases pressure on the lower back and leads to muscle pain and impaired balance.
• Liver and spleen: They may move slightly from their normal position, but they adapt gradually without significant impact on their functions.

How can these symptoms be alleviated?
• Modifying sleeping and sitting positions: Sleeping on the left side and sitting upright with lower back support helps reduce pressure and improve blood circulation.
• Small, frequent meals: reduces pressure on the stomach and reduces reflux and heartburn.
• Gentle movement and stretching: Walking and daily stretching exercises improve blood circulation and relieve back pain and constipation.
• Breathing exercises or light yoga: help improve lung capacity and relieve the feeling of shortness of breath.
• Hydration and fiber intake: Drinking water and eating vegetables, fruits, and whole grains support digestion and reduce constipation.
• Regular rest: Rest periods and elevation of the feet relieve fatigue and reduce swelling.

When should you see a doctor?

Medical consultation is required immediately if abnormal symptoms appear, such as severe or sudden pain, bleeding, severe shortness of breath, dizziness or fainting, a noticeable change in fetal movement, persistent difficulty urinating, or severe swelling in the extremities.

When do the organs return to normal?

After birth, as the uterus gradually returns to its normal size, the organs regain their original positions within a period of approximately two months, with a noticeable improvement in breathing and general comfort during the first days after birth.
