What symptoms of pregnancy do you experience in the 27th week?

As the body changes, you experience the following symptoms this week:

  • Weight gain, as per the BMI (7):
BMIBelow 18.518.5 – 24.925 – 29.930 and Above
Weight gain (Pounds)15-2414-217-166-12
  • Leg cramps are a discomfort usually experienced during the night time. Magnesium or calcium deficiency could also be a reason for this.
  • Backaches due to the pressure exerted by the extra weight of the baby on the hips and the lower back.
  • The digestion process slows down as the progesterone hormone relaxes the digestive tract, leading to constipation.
  • An extra pressure exerted on the nerves in the pelvic and rectal areas causing hemorrhoids.
  • Pressure on the nerves of hands and wrists, due to an increased blood volume, causes a tingling effect called the Carpal Tunnel Syndrome.
  • The extra weight of the baby, body aches, cramps, and frequent urination leads to insomnia.
  • The bladder is compressed by the growing uterus, increasing the frequency of urination.
  • Due to the pressure on the bladder, you may unexpectedly pee while you sneeze, a phenomenon nicknamed ‘snissing’.
  • Excess retention of water in the body causes swelling of the legs, hands, and face, also known as edema. Drinking a lot of water helps expel the excess water.
  • The loosening of the gums, due to hormonal fluctuations, make it more sensitive causing bleeding of the gums.
  • Increased blood flow to the lower part of the body results in reduced blood flow to the brain, causing dizziness.
  • Restless Leg Syndrome (RLS) is the uncontrollable urge to move the legs to relieve the uncomfortable tingling effects. This disorder is also known as Willis-Ekbom Disease. Low hemoglobin (<11 g/dl) level, low folate or iron levels, a history of RLS before conception, or RLS during the previous pregnancy could be a reason for this syndrome (8).
  • The nasal membranes open up due to hormonal changes, resulting in more mucus secretion that further leads to a stuffy nose or nasal congestion.
  • Round ligament pain due to the stretching of muscles and ligaments in the lower abdomen.
  • Braxton Hicks contractions are irregular and less painful contractions that help prepare the body for labor. They go away after you try switching your positions.

Your OB/GYN Visit

The OB/GYN visit this week will include:

  • Weight and blood pressure check-up
  • Measuring the fundal height
  • Urine test
  • Ultrasound scanning in case of twin pregnancy or high-risk pregnancies to monitor the fetal growth.
  • Glucose tolerance test: This is a screening test to check the blood sugar level. It involves two approaches, one step or two step (14).
  • One step (OGTT): Fasting blood sugar levels are tested, following which you have to drink 75 gm of glucose. The blood is drawn again for testing, at intervals of 1 hour and 2 hours to measure the glucose levels.
  • Two-step: A blood sample is drawn one hour after you drink 50 gm of glucose. This test is called the glucose challenge test. In case of an abnormal test result, a glucose tolerance test is done. Blood is drawn during fasting, and later at intervals of one, two, and three hours to check the glucose levels. Any abnormality in the test result indicates gestational diabetes.

Take the prescribed medications, if any, and follow the lifestyle and dietary changes that the doctor recommends to keep gestational diabetes and other conditions at bay.
