How Long Does Morning Sickness Last?
If you are in the grip of morning sickness, one of the first questions you will have is how long it will last. The good news is that for most women it is a temporary phase tied to the first trimester, though the exact duration varies. Here is a clear guide to the typical timeline and what to do if it lingers.

The Typical Duration
For the majority of women, morning sickness lasts from around week 6 to week 12 or 14, easing as the first trimester ends. Symptoms usually build gradually, peak between weeks 8 and 10, and then taper off. Some women find nausea disappears suddenly, while for others it fades slowly over several days. Both patterns are normal, and the duration does not indicate anything about the health of your pregnancy.Why It Eases
Morning sickness tends to improve as hCG levels plateau and then decline after the first trimester. By around week 10 to 12, the placenta takes over hormone production and levels stabilise, which for many women brings relief. Progesterone levels also stabilise, and the body adjusts to the hormonal changes, reducing nausea and sensitivity.When It Lasts Longer
Some women continue to feel nauseous into the second trimester, and a smaller number experience symptoms throughout pregnancy. This is more common in women carrying twins or higher multiples, those with a history of motion sickness, and those who had nausea in previous pregnancies. Persistent nausea beyond the first trimester is usually manageable, but speak to your midwife if it affects your eating or wellbeing.Hyperemesis Gravidarum
If nausea and vomiting are severe, persistent, and prevent you from keeping food or fluids down, you may have hyperemesis gravidarum. This is a more serious condition that can lead to dehydration and weight loss and may require treatment with anti-sickness medication, fluids or hospital care. Do not struggle alone; seek medical help if you are vomiting multiple times a day, feel dizzy, or notice dark urine.FAQ
### Does morning sickness lasting longer mean a healthier pregnancy?Not necessarily. Studies do not consistently show that longer nausea means a better outcome. Duration varies between individuals and pregnancies.
Can morning sickness come back in the third trimester?
Yes, some women experience a return of nausea late in pregnancy due to hormones, pressure on the stomach, or acid reflux. Mention it to your midwife so they can rule out other causes.
Is it normal to still feel sick at 16 weeks?
A minority of women still have nausea at 16 weeks. It often continues to ease after this point, but if it is affecting your daily life, ask your midwife about anti-sickness options.
