When Does Morning Sickness Start? A Comprehensive Guide to Understanding and Managing Early Pregnancy Symptoms

If you're expecting a little one, you might be wondering when morning sickness starts and how to manage this common, yet often challenging, early pregnancy symptom. In this comprehensive guide, we'll explore everything you need to know about morning sickness, from its onset to effective management strategies.

Pregnancy is a beautiful journey filled with excitement, anticipation, and, unfortunately, some uncomfortable symptoms. Morning sickness is one such common symptom that many pregnant individuals experience. Understanding when morning sickness starts and how to manage it effectively can make a significant difference in your overall well-being during pregnancy. In this article, we'll dive deep into the world of morning sickness, providing you with valuable insights and practical tips to help you navigate this often challenging phase of pregnancy.

When Does Morning Sickness Start?

Morning sickness typically begins around the sixth week of pregnancy and tends to subside by the fourteenth week. However, it's essential to note that every pregnancy is unique, and some individuals may experience morning sickness for a longer duration or even throughout their entire pregnancy.

It's also worth mentioning that morning sickness can start as early as a few weeks after conception, making it one of the first signs of pregnancy for some people. So, if you've recently discovered that you're pregnant and are already experiencing nausea and vomiting, you're not alone.

Morning Sickness: Not Just a Morning Issue

Despite its name, morning sickness can occur at any time of the day or night. Some pregnant individuals may feel nauseous all day long, while others may experience nausea triggered by specific smells or foods. This variation in symptoms can make morning sickness a particularly challenging aspect of pregnancy to navigate, as it can be difficult to predict when and how it will manifest.

In some cases, pregnant individuals may find that their morning sickness is more severe during the morning hours, possibly due to low blood sugar levels after a night of fasting. However, it's essential to recognize that morning sickness is not limited to the morning and can strike at any time.

Causes of Morning Sickness

The exact cause of morning sickness remains unknown, but several factors are believed to contribute to its onset. Some of the possible causes of morning sickness include:

  • Hormonal changes: During pregnancy, the body undergoes significant hormonal changes, particularly in the levels of human chorionic gonadotropin (hCG) and estrogen. These hormonal fluctuations are believed to play a role in the development of morning sickness.

  • Slowed gastric emptying: Pregnancy can slow down the rate at which food moves through the gastrointestinal tract, leading to a condition known as gastric stasis. This slowed gastric emptying may contribute to feelings of nausea and vomiting.

  • Genetic factors: Research suggests that there may be a genetic component to morning sickness, with some individuals being more predisposed to experiencing it than others.

  • Psychological factors: Some studies have indicated that psychological factors, such as stress and anxiety, may play a role in the development of morning sickness. However, more research is needed to fully understand the relationship between psychological factors and morning sickness.

Morning Sickness and Its Impact on the Baby

In most cases, morning sickness is not harmful to the baby. However, if morning sickness becomes severe and leads to dehydration or significant weight loss, it can pose risks to both the pregnant individual and the baby. This severe form of morning sickness is called hyperemesis gravidarum and affects between 0.3% to 3% of all pregnancies.

Hyperemesis gravidarum can potentially lead to complications such as electrolyte imbalances, malnutrition, and an increased risk of preterm birth. If you suspect that you may be experiencing hyperemesis gravidarum, it's crucial to consult your healthcare provider as soon as possible to receive appropriate treatment and support.

Managing Morning Sickness

While morning sickness can be an uncomfortable and challenging aspect of pregnancy, there are several strategies you can implement to help manage your symptoms effectively. Some of these include:

  • Eating small and frequent meals: Consuming smaller meals more frequently throughout the day can help stabilize your blood sugar levels and prevent feelings of nausea associated with an empty stomach.

  • Avoiding spicy and fatty foods: Spicy and fatty foods can be harder to digest and may exacerbate morning sickness symptoms. Opt for bland, easy-to-digest foods, such as crackers, toast, and rice, to help alleviate nausea.

  • Drinking plenty of fluids: Staying well-hydrated is essential during pregnancy, particularly if you're experiencing morning sickness. Aim to drink at least eight cups of water per day, and consider adding electrolyte-rich beverages like coconut water or sports drinks if you're struggling with dehydration.

  • Brushing your teeth after eating: Brushing your teeth after meals can help remove any lingering tastes or smells that may trigger nausea.

  • Avoiding triggers: If you've identified specific triggers for your morning sickness, such as strong odors or heat, do your best to avoid these triggers whenever possible.

In addition to these lifestyle and dietary changes, some individuals may benefit from taking vitamin B6 supplements, ginger products, or anti-nausea medications prescribed by their healthcare provider. However, it's essential to consult with your healthcare provider before starting any new supplements or medications during pregnancy to ensure they are safe and appropriate for your unique situation.


Morning sickness is a common and often challenging aspect of pregnancy, but understanding when it starts and how to manage it effectively can make a significant difference in your overall well-being. By implementing dietary and lifestyle changes, consulting with your healthcare provider, and staying informed about your pregnancy journey, you can navigate morning sickness with confidence and ease.

Remember, every pregnancy is unique, and it's essential to listen to your body and seek personalized advice and support from your healthcare provider throughout your pregnancy journey.
