Morning Sickness

Morning sickness

Early on in pregnancy has its share of discomforts. Some, such as mild nausea and fatigue, are almost universal. Others, including nosebleeds and bladder infections, are less common.

Soon after you conceive, your body begins a series of major changes that enable it to sustain your baby through 37 weeks of growth and development. The glands of your endocrine system and placenta step up hormone production. Your blood volume increases and your uterus expands.

By the fourth month of pregnancy, you’ll begin to feel much more like your old self, presumably because your body has adjusted somewhat to these dramatic changes. Until then, you can rest assured that first-trimester symptoms are almost always associated with normal pregnancies that have good outcomes. Morning sickness and the other ailments that occur around this time are almost always mild enough to manage on your own. Here’s a rundown of the most common first-trimester symptoms.

How common morning sickness?

Up to 70 percent of expectant mothers have nausea, sometimes with vomiting, early in pregnancy. Queasiness may be most noticeable in the morning, but it can occur at any time. Even if you aren’t nauseated, you may develop aversions to certain foods, such as coffee and meat, partly because of their odors. As long as you continue to eat a healthy diet and get all the nutrients you need, food aversions aren’t a cause for concern.

What causes it?

The exact cause is unclear, but pregnancy hormones that relax the stomach may play a role.

How long does it last?

It generally improves by the 13th or 14th week of pregnancy, but some women continue to feel queasy from time to time well into the second trimester.
