There are those who can no longer enter a bar, to avoid the smell of coffee, and those who can no longer open the refrigerator or bear the scent of their colleagues.

It is a phenomenon very common during pregnancy, but what is it about? "In the first trimester of gestation, some women develop greater olfactory sensitivity, which is called"iperosmia gravidica"It is a biological phenomenon, linked to hormonal changes and the increase in olfactory cells. It ensures that smells are perceived more clearly, even if faint or distant," explains Scavello, midwife of the Santagostino Medical Center in our city. It may happen that some of these scents, previously appreciated, become intolerable, but also the opposite.

Unpleasant odors in pregnancy

Among the smells that are most disgusting to expectant mothers are:

  • fish, both cooked and raw;
  • raw meat;
  • the eggs;
  • the coffee;
  • intense aromas;
  • the sweat;
  • food for animals and the animals themselves;
  • the smoke;
  • chemicals;
  • the interiors of the cars
  • and gasoline.

One of the worst annoyances caused by these odors in predisposed women is the sense of nausea. The natural remedies to combat it are different and among these there is the consumption of ginger and chamomile.

Scholars believe that this condition, due to the increase in hormones in the body of pregnant women, has two purposes: «one is protective and consists in removing the woman from things that could be harmful, such as polluted foods or environments; the other is evolutionary. The greater sensitivity to odors would in fact be a natural adaptation, which occurs in all mammals, to ensure olfactory recognition between the mother and the baby after childbirth ».

Smells in pregnancy, when they start (and end)

This hypersensitivity to odors is a very common symptom of pregnancy and occurs as early as fifth-seventh week.

It can be more or less marked depending on the person: «In general, there are women who are more olfactory than others and this regardless of pregnancy».

With time, the discomfort tends to disappear and already from the fourth month it is much lessened. "But don't worry if you don't notice any changes: each woman is unique and lives the nine months of pregnancy differently".
