Understanding Night Sickness During Pregnancy: Causes, Symptoms, and Treatment

Pregnancy is an exciting moment for any woman, but it comes with various experiences. One of these experiences is morning sickness, a term used to describe nausea and vomiting during pregnancy.

However, some women may experience sickness at night, often referred to as night sickness. While not abnormal, it can be a challenging experience that affects the overall wellbeing of a pregnant woman.

Understanding the causes, symptoms, and treatment of night sickness is crucial to ensure a smooth pregnancy. This article explores night sickness in detail.

What is Night Sickness?

As the name suggests, night sickness is nausea and vomiting during the night, or right before bed. While it can occur at any stage of pregnancy, it is more common in the first trimester. It is estimated that up to 80% of women experience morning sickness, but not all of them experience night sickness.

What Causes Night Sickness?

The exact cause of night sickness remains unknown. However, it is believed to be related to the hormonal changes that occur during pregnancy. Pregnant women experience a surge in hormone levels, including human chorionic gonadotropin (HCG), estrogen, and progesterone. These hormones are responsible for various pregnancy symptoms, including morning sickness and night sickness.

Other factors that may cause or worsen night sickness include stress, fatigue, hunger, and changes in blood sugar levels. Poor diet, dehydration, and certain smells or foods may trigger nausea and vomiting at night.

Symptoms of Night Sickness

Night sickness is characterized by nausea and vomiting. The severity and frequency of these symptoms vary from woman to woman. Some women may experience mild nausea, while others may have severe vomiting that disrupts sleep. Other symptoms may include dizziness, fatigue, and loss of appetite.

It is crucial to note that while night sickness is generally not harmful, severe vomiting can result in dehydration, electrolyte imbalances, and weight loss. If vomiting persists and is accompanied by other severe symptoms, seeking medical attention is necessary.

Tips for Managing Night Sickness

While there is no one-size-fits-all solution for managing night sickness, the following tips may help ease the symptoms:

  • Eat small, frequent meals throughout the day to avoid an empty stomach.
  • Avoid foods that trigger nausea and vomiting.
  • Stay hydrated by drinking plenty of fluids, such as water and electrolyte drinks.
  • Get plenty of rest and avoid stressful situations.
  • Practice relaxation techniques, such as deep breathing and yoga.
  • Take prenatal vitamins as prescribed by your healthcare provider.

It is also essential to seek medical attention if night sickness persists or worsens despite trying various remedies.

Treatment for Night Sickness

Treatment for night sickness depends on the severity and cause of the symptoms. In most cases, home remedies such as eating small meals, staying hydrated, and avoiding triggers help to ease the symptoms. However, if the symptoms are severe, medication may be necessary.

Antiemetic medications, such as doxylamine and pyridoxine (Diclegis), are often used to treat morning sickness and night sickness. These medications are considered safe for pregnant women and effectively reduce nausea and vomiting. Other medications, such as ondansetron (Zofran), may be prescribed for severe cases of vomiting.

It is essential to discuss any medications with your healthcare provider to ensure their safety during pregnancy.

When to Seek Medical Attention

While night sickness is generally not harmful, severe vomiting can result in dehydration, electrolyte imbalances, and weight loss. You should seek medical attention if:

  • You cannot keep food or fluids down for more than 24 hours
  • You show signs of dehydration, such as a dry mouth, dark urine, and dizziness
  • You experience rapid weight loss
  • You have severe abdominal pain or chest pain
  • You have a fever or other signs of infection


Night sickness is an experience that some pregnant women undergo, and it can be challenging to manage. However, understanding the causes, symptoms, and treatment options can ease the experience and ensure a smooth pregnancy. Home remedies, such as eating small meals, staying hydrated, and avoiding triggers, are generally effective in managing night sickness.

However, if symptoms persist or worsen, medication and medical attention may be necessary. Remember to consult with your healthcare provider before taking any medications to ensure their safety during pregnancy.
