When to consult a doctor for morning sickness?

If vomiting is severe or ongoing

See a doctor if you are unable to keep food or fluids down for more than 24 hours, as persistent vomiting can quickly lead to dehydration and complications.

If there are signs of dehydration or weight loss

Consult a doctor if you notice dark urine, dizziness, infrequent urination, or significant weight loss due to ongoing nausea and vomiting.

If symptoms are extreme or suggest hyperemesis gravidarum

Seek medical attention if nausea and vomiting are severe, persistent, and interfere with daily activities, or if they lead to weakness, dehydration, or poor nutrition.

Causes

Causes of morning sickness include a combination of hormonal, physical, and lifestyle factors, such as: 

  • Hormonal changes: Increased levels of pregnancy hormones such as human chorionic gonadotropin (hCG) and estrogen can trigger nausea and vomiting. 
  • Gastric changes: Slower digestion during pregnancy and having an empty stomach can contribute to feelings of nausea. 

Common triggers

Triggers of morning sickness may include: 

  • Sensitivity to odours: Heightened sensitivity to certain smells, such as food, perfumes, or smoke, can trigger nausea. 
  • Time of day: Symptoms are often worse in the early morning or when the stomach is empty. 

Is morning sickness dangerous for the baby?

Mild to moderate morning sickness usually doesn’t harm the baby. However, severe morning sickness may lead to dehydration and weight loss, requiring medical attention.

Home remedies

Many people find relief by trying safe and practical home remedies for morning sickness at home. 

  • Eat smaller, frequent meals – Helps prevent an empty stomach and reduces nausea triggers. 
  • Stay well hydrated – Sipping water or clear fluids can ease nausea and prevent dehydration. 
  • Avoid strong smells – Limiting exposure to strong odours may reduce nausea episodes. 
  • Try ginger – Ginger tea, biscuits, or supplements can help calm the stomach.
