Morning sickness is a common symptom of nausea and vomiting experienced by pregnant women in the early stages of pregnancy, typically starting around 4-5 weeks and improving by 12-14 weeks. This article provides accurate information on the causes, symptoms, management methods, and treatment support policies of morning sickness based on official sources to assist expectant mothers.

What is Morning Sickness?

Morning sickness is a symptom accompanied by nausea and vomiting caused by hormonal changes during pregnancy. Approximately 70-85% of pregnant women experience it, starting between 4-5 weeks after the last menstrual period and peaking at 11-13 weeks.

It naturally improves around 14-16 weeks for most women, though some may continue into later pregnancy. The exact cause is unknown, but changes in hormone levels such as human chorionic gonadotropin (hCG) and estrogen are identified as main factors.

Morning Sickness Symptoms and Severity

Main Symptoms

The primary symptoms of morning sickness are nausea and vomiting, which are especially severe in the morning. Loss of appetite, dizziness, hypersensitivity to smells, fatigue, and general malaise may also accompany these symptoms.

Severity Classification

If morning sickness becomes severe and progresses to hyperemesis gravidarum (extreme vomiting causing dehydration and malnutrition), hospitalization is required. Criteria include more than 5% body weight loss, ketonuria, and electrolyte imbalances. This can threaten the health of both mother and fetus.

Morning sickness severity can be classified as follows. Mild cases feature light nausea and occasional vomiting, manageable through lifestyle improvements. Moderate cases involve frequent vomiting and difficulty eating, requiring consideration of medication. Severe hyperemesis gravidarum involves dehydration and over 5% weight loss, necessitating hospital admission and IV fluid therapy.

Morning Sickness Management and Prevention Methods

Management of morning sickness primarily involves dietary and lifestyle adjustments. Follow official guidelines by eating small amounts frequently and avoiding stimulating foods.

• Avoid greasy and spicy foods, and prefer cold foods.
• Consume foods like ginger tea and lemon that alleviate nausea.
• Maintain adequate hydration by drinking small amounts frequently rather than large quantities at once.
• Get sufficient rest and avoid unpleasant odors.

Taking prenatal multivitamins before pregnancy may help prevent morning sickness.

Treatment and Health Insurance Support

Starting June 2024, morning sickness medication (doxylamine succinate + pyridoxine hydrochloride) has been covered by national health insurance. It can be prescribed if conservative treatments fail, reducing out-of-pocket costs to about 35,000 KRW per month (previously 180,000 KRW without coverage).

The ceiling price for morning sickness medication is 1,303 KRW per tablet for Diclectin sustained-release tablets (original licensed drug) and 1,175 KRW for Prillectin sustained-release tablets (generic drug).

This policy may change annually, so check the latest notices. Registered pregnant women at public health centers can also receive iron and folic acid supplements.

Common Misconceptions and Precautions

A common misconception is that morning sickness is a natural symptom that must be endured. However, severe cases can lead to nutritional deficiencies and impaired fetal development, making early management essential.

• Visit a medical institution immediately if signs of dehydration (dizziness, reduced urine output) appear.
• Avoid self-diagnosis and consult a specialist.
• Confirm with a doctor’s prescription before taking any medication.

Refer to official announcements considering possible policy changes.

Essential Checks Before Applying for Morning Sickness Support

Before receiving morning sickness-related support or treatment, verify the following directly on official government or public institution websites.

• Your pregnancy week and symptom severity (mild/severe classification criteria).
• Health insurance coverage conditions and out-of-pocket costs for morning sickness medication (varies by year).
• Public health center pregnancy registration status and additional support (iron supplements, etc.).
• Regional medical institution availability hours and emergency response methods.

This verification process allows accurate grasp of the latest information.

Next Steps for Morning Sickness Relief and Health Management

If morning sickness symptoms persist, visit a nearby obstetrics and gynecology clinic or public health center for consultation. Practice ongoing health management by checking the latest policies and guidelines through official announcements from the Ministry of Health and Welfare or Korea Disease Control and Prevention Agency.
