Pregnancy week 25
At a whopping 1 1/2 pounds and a massive 9 inches at week 25, the baby is developing spinal structures, lung blood vessels, nostrils, and layers of fat that will soon take away the transparency of it’s skin. Also at this point, the baby can make a fist with it’s new formed dexterity. Sever back pain is a common symptom of week 25 of pregnancy because of the expanding uterus and the pressure it places on the back and pelvic bones. Sciatica can develop as a result of the baby’s head pressing against the nerves in the lower back and legs. This painful condition can be alleviated or helped by a hot or cold ice pack, a firm mattress, good posture at all times, a body pillow in bed, and sometimes physical therapy if the situation warrants and if a physician recommends it. At this point, pre-term labor symptoms should be talked about with a physician and thoroughly understood by a mother to be. Meals become harder to digest as the weeks progress because progesterone makes a woman more prone to heartburn and indigestion. Vitamin C is good at helping the body absorb iron from the food it takes in. Also at week 25 of pregnancy, because of the pressure on the uterus, it is not uncommon for the bladder to leak, especially during a fit of laughter or a cough. However, if the fluid is suspected to be anything but urine, a physician should be consulted immediately. An ultrasound and vaginal examination can help determine the cause.
At week 25 of pregnancy, the baby’s brain is developing the aspects that allow it to distinguish sensations, observation, thought, and emotions. These developments allow the baby to remember, after it’s birth, events that happened while it was still in the womb. The baby’s bones continue to harder and the fingerprints are completely formed. The baby can even express preference towards the use of it’s right or left hand at this point. The heart of the baby can also be heard by placing an ear to the womb.
Current guidance (today's medical sources): By week twenty-five the baby is building fat, the skin is becoming less see-through, and it may respond to familiar voices. Digestive symptoms such as heartburn and constipation are common, as is difficulty sleeping. Eating smaller meals, staying hydrated, and gentle activity are commonly suggested general comfort measures.
Contact your healthcare provider promptly about heavy vaginal bleeding, severe or persistent abdominal pain, a high fever, severe or sudden headache, vision changes, or fainting. Seek urgent care if you are worried — these can be signs that need medical attention.
