2Changes in the Mother’s Body During the Second Trimester

A myriad of physical changes occur in an expecting mother’s body during this trimester.

  • As the baby grows, a mother’s breasts and belly will expand, and her uterus will enlarge to accommodate the developing child.
  • Afternoons and evenings may be marked by Braxton Hicks contractions, which are practice contractions that prepare the body for labor.
  • Skin changes are common, including the appearance of a dark line down the center of the abdomen, as well as changes in pigmentation on the breasts, buttocks, and abdomen.
  • Nosebleeds, a stuffy nose, and nasal congestion may occur due to increased blood flow to the mucous membranes.
  • Dental issues such as gum bleeding and tooth decay can arise, so maintaining oral hygiene is crucial.
  • Leg cramps and dizziness are also possible side effects of the changing body.
  • Urinary tract infections can lead to cloudy or foul-smelling urine and a loss of bladder control, so prompt treatment is essential.

Emotionally, expectant mothers may experience a range of feelings during this trimester.

It is common for mothers-to-be to feel anxious about the upcoming birth. However, it is important to prioritize rest and adopt a healthy lifestyle to ensure a safe and healthy delivery.

Frequently asked questions

The second trimester of pregnancy is often referred to as the ‘honeymoon phase’. It spans from week 13 to week 27 of pregnancy, and is typically a time when many of the unpleasant symptoms of early pregnancy subside, and energy levels return.

During this period, a woman’s body continues to undergo significant changes. The growing uterus pushes against the stomach, which can cause heartburn and indigestion. Back pain and round ligament pain are also common as the body adjusts to support the increasing weight of the baby. Breast changes, such as enlargement and darkening of the areolas, also occur.

Symptoms like nausea and fatigue often improve, but new discomforts may arise. These can include backache, leg cramps, varicose veins, hemorrhoids, and skin changes such as stretch marks and dark patches on the face (chloasma). Vaginal discharge and increased urinary frequency may also be experienced.

A healthy diet is crucial. Iron-rich foods, such as lean meats, leafy greens, and legumes, are essential to support the increased blood volume and prevent anemia. Calcium and vitamin D are also important for bone health, and can be obtained from dairy products, dark leafy greens, and fatty fish like salmon. Folic acid supplementation should continue to reduce the risk of neural tube defects.

Moderate-intensity exercises like walking, swimming, and prenatal yoga are encouraged to maintain fitness and prepare the body for labor. Kegel exercises are also beneficial for strengthening the pelvic floor muscles. However, it’s important to avoid strenuous activities and to consult with a healthcare provider before starting any new exercise routine.

The anatomy scan, or level II ultrasound, is usually performed between weeks 18 and 22. This detailed ultrasound examines the baby’s organs, bones, and overall development. Blood tests, such as the quad screen or sequential integrated screening, may also be offered to assess the risk of chromosomal abnormalities. Glucose screening is done to check for gestational diabetes.

Besides a healthy diet and regular exercise, adequate rest and sleep are crucial. Managing stress through relaxation techniques, such as meditation or prenatal massage, can also be beneficial. It’s important to stay hydrated, and to avoid harmful substances like alcohol, tobacco, and illicit drugs. Regular prenatal care and prompt reporting of any concerns to a healthcare provider are essential for a healthy pregnancy.
