What Symptoms Of Pregnancy Do You Experience In The 25th Week?

The common symptoms in this week include:

  1. Weight gain: The weight gain should be based on the BMI (8):
BMIBelow 18.518.5 – 24.925 – 29.930 and Above
Weight gain (Pounds)14-2112-198-145-11
  1. Trouble sleeping: Besides the bodily discomforts, frequent breaks to the bathroom during the night can disturb the sleep.
  1. Frequent urination: The pressure exerted by the growing uterus on the bladder increases the urge to urinate.
  1. Constipation: Progesterone relaxes the muscles of the digestive tract, which slows down the digestion process causing constipation.
  1. Hemorrhoids: Increased blood flow and constipation cause the veins in the rectal area to swell.
  1. Gas and bloating: Indigestion generates gas and makes you feel bloated.
  1. Heartburn: The growing uterus puts pressure on the stomach, which pushes the gastric acids up into the esophagus, causing heartburn.
  1. Back pain: The pressure exerted by the extra weight of the baby on the lower back can cause aches in the region.
  1. Fatigue: Since the body is working harder to nurture the baby, you’ll feel tired than usual.
  1. Edema: The water retention in the body causes swelling of hands and feet.
  1. Braxton Hicks contractions: You may experience irregular and less painful contractions that go away when you switch positions. The contractions are the body’s way of preparing for labor and delivery.
  1. Carpal tunnel syndrome: A tingling effect is felt in the hands and wrist, due to the increased blood volume that exerts pressure on the nerves.
  1. Snoring: An increase in the blood flow to the mucous membranes can cause nasal congestion and make you snore.
  1. Symphysis pubis dysfunction (SPD): This is a condition where the ligaments and the muscles of the pelvic joints are stretched, causing pain in the pelvic area. Pelvic tilts and kegel exercises help strengthen the muscles of pelvic area (9).
  1. Restless leg syndrome (RLS): Also known as Willis-Ekbom Disease, this condition causes a tingling effect in the legs along with an uncontrollable urge to move them. A low ferritin level in the blood (hemoglobin <11 g/dl), low folate, history of RLS before conception, RLS during the previous pregnancy are a few common reasons for this syndrome (10).

In addition to these, you might experience certain emotional and physical changes in this week.

Preterm Labor At 25 Weeks Of Pregnancy

Preterm labor is when the labor starts between 20 and 37 weeks of pregnancy (12). Babies born between 24 and 28 weeks of pregnancy are considered to be extremely premature with their weight less than 1000g (2.2lb) (13). They are usually kept in the neonatal intensive care unit (NICU) with life support systems and have an 82% chance of survival if they weigh in the range of 751-1000g.

Extremely premature babies can develop severe disabilities like chronic lung disease, cerebral palsy, blindness, SIDS (sudden infant death syndrome), mental retardation, and deafness (14, 15).

Your OB/GYN Visit

Here is what you can expect during your OB/GYN visit:

  • Weight check
  • Blood pressure
  • Glucose tolerance test: If the glucose challenge test results are abnormal, the doctor would suggest the glucose tolerance test to measure the sugar level in the mother’s bloodstream.

For the glucose challenge test, blood is drawn an hour after you drink glucose water, and is checked for increased blood sugar levels. In case of a positive test result, a glucose tolerance test will be done. This requires overnight fasting and blood will be drawn before you break the fast and is tested for sugar levels.

This is followed by an hourly blood test for the next three hours. An abnormal test result is an indication of gestational diabetes (11).

The doctor would recommend a healthy, low-sugar diet to keep gestational diabetes, if you have it, in control. Otherwise, you can follow a healthy diet and lifestyle to keep yourself and your baby healthy.
