When Does Morning Sickness Start?

When Does Morning Sickness Start?

For most pregnant women, morning sickness starts in the first trimester. More often than not, it is when it is around the mid-half of the first trimester. Roughly, it should be noticed around the moment women are 6 weeks gone in pregnancy.

Does Morning Sickness Happen in the Morning?

Although it goes by the name “morning sickness”, the symptoms associated with this pregnancy sign can happen any other time of the day. It could be in the evening, afternoon, or at night. The discomfort of morning sickness is one of the numerous things expectant moms will have to bear. This is even before they start showing visible signs of pregnancy.

What Are the Symptoms of Morning Sickness?

Of course, expectant women feel sick and this is usually characterized by vomiting & nausea. It is not by accident that it is termed morning sickness. This is because these symptoms are more likely to show up in the morning’s early hours. But as mentioned earlier, the morning sickness symptoms can also show up at other times in the day.

So, you should not be surprised if it shows up at unexpected hours. But also worth knowing is that the uncomfortable symptoms will subside as time goes on. It might not completely subside, but it should get better from the middle or towards the latter week and days of the second trimester. That would be weeks 13 – 27.

Will Every Pregnant Woman Experience Morning Sickness?

Not all women experience morning sickness during pregnancy. A few have a smoother sail void of this pregnancy’s signs and symptoms. However, the chances of experiencing morning sickness for pregnant women are very high.

It is such that between 3 – 4 out of every 5 pregnant women will experience it. However, it is more intense for some, and less intense for others. For the record, some people claim that natural remedies like drinking ginger ale will help relieve the symptoms. Well, you can find out more about that.

Causes of Morning Sickness during Pregnancy

Causes of Morning Sickness during Pregnancy

Of course, there are clinically proven reasons why this experience shows up during pregnancy. But to be completely honest, there are still studies as some things are not clear. Now that you are aware of that, some proven reasons based on medical studies include:

  • Reduced level of blood sugar
  • Increased activities of certain hormones
  • Fatigue & stress
  • Effects of certain foods and smells as triggered by a heightened sense of taste and smell

As common as it is, most cases of morning sickness will not require seeing the doctor, going to the clinic, or seeing a health care specialist. This is because the health of the baby and expectant mom is not adversely affected. Of course, this is except for prenatal or antenatal appointments.

However, very chronic and intense morning sickness feeling may be suggestive of a condition called Hyperemesis Gravidarum. It is an extreme measure of the same symptoms and more. But in addition to that, such people feel headaches and quickly get dehydrated.

Seeing a doctor, a healthcare professional, or going to the clinic, is the right thing to do for those with Hyperemesis Gravidarum. But first, deal with the adverse effects of dehydration by drinking enough water.

Things can get worse for pregnant women and people with Hyperemesis Gravidarum who do not seek medical attention on time. This is why you should be aware of the symptoms and signs of this condition which include:

  • Drastic weight loss – weight loss accounting for over 10 pounds while pregnant
  • Constant vomiting
  • Very prone to symptoms & signs of dehydration – Heart beating at a very fast pace, constant thirst, and frequent urination
  • You are fond of feeling lightheaded and/or dizzy

Seeing your doctor is essential if you experience any of these feelings during pregnancy, as it could get worse with time. So, time is of the essence.


Morning sickness is not something strange during pregnancy (for the many pregnant women that experience it). However, very chronic and severe signs and symptoms may suggest something else – Hyperemesis Gravidarum. This would require seeing your doctor.
