Overview

Morning sickness is feeling like throwing up, also called nausea, and throwing up, also called vomiting, that occurs during pregnancy. Despite its name, morning sickness can strike at any time of the day or night.

Many people have morning sickness, especially during the first three months of pregnancy. But some people have morning sickness all through pregnancy. Home remedies, such as snacking during the day and sipping ginger ale or taking medicine you can buy without a prescription, might help relieve nausea.

Rarely, morning sickness is so bad that it turns into hyperemesis gravidarum. This is when the nausea and vomiting cause serious fluid loss or loss of more than 5% of pre-pregnancy body weight. Hyperemesis gravidarum might require going to a hospital for treatment.

Symptoms

Nausea, with or without vomiting, is common in pregnancy. Morning sickness is often brought on by smelling certain odors or eating certain foods.

Morning sickness is most common during the first three months of pregnancy. It typically starts before nine weeks. Symptoms usually improve by the middle or end of the second three months of pregnancy.

When to see a doctor

Contact your health care provider if:

  • You produce no urine or only a little urine that's a dark color
  • You can't keep liquids down
  • You feel dizzy or faint when you stand up
  • Your heart races

Causes

The cause of morning sickness is not known. Hormone changes might play a role. Rarely, a medical condition not related to pregnancy, such as thyroid or gallbladder disease, can cause serious nausea or vomiting.

Risk factors

Morning sickness can affect anyone who's pregnant, but it might be more likely for those who:

  • Had nausea or vomiting from other causes before becoming pregnant, such as motion sickness or migraines
  • Had morning sickness during a prior pregnancy
  • Are pregnant with twins or other multiples

Hyperemesis gravidarum might be more likely for those who:

  • Are pregnant with a girl
  • Have a family history of hyperemesis gravidarum
  • Have had hyperemesis gravidarum during an earlier pregnancy

Complications

Mild nausea and vomiting of pregnancy usually won't cause harm.

If left untreated, severe nausea and vomiting can cause a lack of bodily fluids, a condition known as dehydration. It also may lead to an imbalance in electrolytes — the salts in blood that control the balance of fluids in the body. Severe nausea and vomiting may result in less urine output. Research is mixed on whether hyperemesis gravidarum causes poor weight gain for the baby during pregnancy.

Prevention

There's no sure way to prevent morning sickness. However, taking a daily vitamin supplement before and during pregnancy might help.

Can you feel nauseous 3 days after conception?

It's unlikely that you will experience any pregnancy symptoms at 3 DPO. The luteal phase starts the day that you ovulate and continues until you have your first day of bleeding (not spotting).

Is it possible to feel nauseous immediately after conception?

Nausea immediately after sex is something you may question as a sign of pregnancy. However, your body doesn't have enough time to react to produce that symptom due to a pregnancy resulting from recent intercourse. For most pregnant people, pregnancy-related nausea begins two to eight weeks following conception.

How quickly do you get nausea when pregnant?

Also called morning sickness, nausea usually begins at around six weeks, peaks between weeks 8-11, and typically fades near the end of the first trimester. However, some women experience nausea as both a second trimester and third trimester symptom.

What symptoms do you have at 1 week pregnant?

The first signs of pregnancy won't occur right away—in fact, many women miss their period at week 4 before they begin to feel “different.” But some common early signs of pregnancy in the first weeks after fertilization include breast soreness or tenderness, nausea, fatigue and the frequent urge to pee.
