You look and feel like a fat cow trust me, I know this from experience. You feel bloated. You have to piss like Seabiscuit every 20 minutes. Medical disability requiring full bed rest frequently ordered during part of many pregnancies varying from days to months for health of either mother or baby. Aggravation of pre-pregnancy diseases and conditions e.
Research now indicates a possible link between ovarian cancer and female fertility treatments, including "egg harvesting" from infertile women and donors research also now indicates correlations between lower breast cancer survival rates and proximity in time to onset of cancer of last pregnancy. Research also indicates a correlation between having six or more pregnancies and a risk of coronary and cardiovascular disease The effects of pregnancy.
But hey, the fetus does "benefit" the mother! By making her feel like she's dying! That's the spirit! One more thing I would like to point out. The zygote actually overpowers the woman's immune system in the same way a parasite does. Isn't that interesting!? Here are some scientific findings:. There you have it, folks. A fetus is a damn parasite and it invades the mother's body like one too. I am the kind of woman who prefers science, studies, and medical facts over throwing pregnancy on the " magical miracle " band wagon.
It is not magical, it's called genetics and biology. God has nothing to do with it either. And it is not a damn miracle! If it happens every damn day, how is that even close to a miracle!? A miracle would be a man conceiving and gestating a fetus full term. It may feel magical, but it really isn't. It's just biology! The fetus is a parasite.

NEET Question. Answer to Question. Parasites are invasive organism that come from an outside or external source. A fetus comes from an inside or internal source ie fertilized egg Parasites are generally harmful to the hosts, fetuses may make a pregnant woman experience adverse health effects, but not nearly to the same level that a parasite generally does. A parasite makes direct contact with the host's living tissues.
A fetus lives in the placenta, fed by the umbilical cord, both of which are fetal tissue ie the cells come from the baby. When a parasite invades a host, the host tissue will usually respond by encapsulating the parasite in order to cut it off from other surrounding tissue. Through all this manipulation and mutual reprisal, most of the time the foetus ultimately gets about the right amount of blood, and about the right amount of sugar, allowing it to grow fat and healthy in time for birth.
As long as each side holds its end up, nobody gets hurt. B ut what happens when things go wrong? Since the turn of the millennium, the Human Genome Project has provided a wealth of data, most of which remains incomprehensible to us.
Yet by looking for signs of genomic imprinting — that is, genes that are expressed differently depending on whether they are inherited from the father or the mother — researchers have been able to pin down the genetic causes of numerous diseases of pregnancy and childhoods. Genomic imprinting, and the maternal-fetal battle behind it, have been shown to account for gestational diabetes, Prader-Willi Syndrome, Angelman Syndrome, childhood obesity and several cancers.
Researchers suspect that it may also underlie devastating psychiatric conditions such as schizophrenia, bipolar disorder and autism. In , Ian Morison and colleagues compiled a database of more than 40 imprinted genes. That number had doubled by ; by , it had nearly doubled again.
Identifying genetic mechanisms does not in itself provide a cure for these complex diseases, but it is a vital step towards one. Preeclampsia, perhaps the most mysterious disease of pregnancy, turns out to be a particularly good example of the way in which the evolutionary, genetic and medical pictures are all lining up.
More than two decades ago, Haig suggested that it resulted from a breakdown in communication between mother and foetus. In , Jenny Graves expanded on this idea, suggesting that it could be explained by failure of imprinting on a maternally inherited gene. This story shows how, with the help of evolutionary theory, we are at last starting to make sense of the grim, tangled mess that is human development. Foetal hormones counter this effect by raising her blood pressure.
Several hormones are involved when the maternal arteries expand during early pregnancy. If these chemicals get out of balance, those arteries can fail to expand, starving the foetus of oxygen.
If that happens, the foetus sometimes resorts to more extreme measures. This risks kidney and liver damage, if not stroke: the symptoms of preeclampsia. In , researchers showed that the maternally inherited gene H19 is strongly associated with the disease. This was just as Jenny Graves predicted.
H19 is known to be crucial to early growth of the placenta. Changes in several other maternally inherited genes, and some paternally inherited ones, are also suspected of being involved. Our huge brains and our traumatic gestation seem intimately connected; at the very least, they are both extraordinary features of humanity.
Did the ancients guess this connection when they crafted their mythologies? Be that as it may, if we want to reduce the danger and suffering of pregnancy, the only way out is through. We need more knowledge — lots of it. Space exploration. Instead of treating Mars and the Moon as sites of conquest and settlement, we need a radical new ethics of space exploration. Ramin Skibba. Modern biomedicine sees the body as a closed mechanistic system. But illness shows us to be permeable, ecological beings.

Even with the help of modern medicine, pregnancy still kills about women every day worldwide That insight led Haig to found the theory of genomic imprinting , which explains how certain genes are expressed differently depending on whether they come from your father or your mother.
