Pregnancy is the biological process that involves the fertilization and following development of a single or multiple embryos. A normal pregnancy lasts about thirty eight weeks after conception and is many societies is divided into three trimesters, in which the first trimester is characterized by a high miscarriage risk. Miscarriage refers to the natural death of the embryo or fetus. The second trimester brings about easy monitoring and diagnosing of the condition of the fetus. In the third trimester, we can determine whether the fetus can survive outside the uterus, either with out or with required medications. During pregnancy, the body undergoes major changes to foster the development of the fetus, there are also increased levels of HCG and Progesterone and can cause great discomfort in many women. Most of these changes have been classified as symptoms that are common to all pregnancies.
The symptoms of pregnancy can vary among women, some experience associated discomfort within days of conception, others within weeks, while some women don’t experience any discomfort at all. Symptoms may include nausea and vomiting which can begin around the first week of pregnancy, you could try eating small frequent meals or saltine crackers for some relief, drinking a protein- carbohydrate at night may decrease morning nausea. There is no explanation behind morning sickness and therefore no solution. The increased levels of HCG hormone cause the breasts to enlarge and become tender it will also make you feel tired and irritable due to major hormonal upheavals, increased amount of progesterone circulating in your body will also cause a spike in body temperature. Other symptoms of pregnancy include light bleeding occurring around eight to ten days from ovulation or a missed menstrual cycle. You will feel dizzy, especially when standing in one position, this is because the uterus applies pressure to major arteries present in the legs causing low blood pressure, it is not advisable to skip meals as it will cause low blood sugar which is a primary source of food for the growing fetus. Digestion will slow down to allow optimum absorption of nutrients, a decrease in the digestion rate will also lead to heartburn. Other symptoms of pregnancy may include changes in appetite, bloating and stomach cramps.
Aside from hormonal changes, there are also physical changes that take place during pregnancy, these are completely normal and take place only to accommodate the growing fetus; there is an increased level of breathing output, cardiac output and blood sugar. The pelvis will tilt backwards while arching your back to help you keep balance, muscles will begin to stretch and low contraction will put your lower back in the right alignment. Weight gain and swelling of the feet, estrogen and relaxin will remodel the ligaments; soft tissue and cartilage are just some of the major physical changes that take place during pregnancy.
The best source of information about pregnancy is probably your doctor, only a trained medical professional will be able to point out any complications that may arise, and will also tell you about the developmental status of your baby. He will also explain what medications to take to ease any physical pain. There are many centers that teach expectant mothers about pregnancy right from dealing with associated symptoms, dealing with back pains, healthy eating habits and techniques to ease labor pain and speed up delivery.
