Morning Sickness

Overview of Morning Sickness

Morning sickness is a condition which occurs during pregnancy that affects approximately more than half of all pregnant women, but it may also be experienced by women using hormonal contraception or hormone replacement therapy. Usually prominent during the early hours of the morning, morning sickness can occur during any part of the day including during the night.

This condition may be experienced only as mild nausea, or it may cause actual vomiting. In only about 1% of all pregnancies, vomiting may become severe enough to cause dehydration, weight loss, alkalosis (a condition in which the pH of the blood is elevated beyond normal and results in hypoventilation as an attempt to balance the pH), and hypokalemia (a condition in which the concentration of potassium (K+) in the blood is low which may result in elevated blood pressure, cardiac arrhythmias, and/or muscle weakness); this severe form of morning sickness is known as hyperemesis gravidarum.

Morning sickness may be one of the earliest signs that a woman may be expecting a child and usually begins around the 6th week of pregnancy, and it seems to cease around the 12th week of pregnancy for most pregnant women which marks the end of the first trimester and the beginning of the second trimester of pregnancy. However, morning sickness may continue throughout the entire pregnancy for some women.

Alternative names of Morning Sickness

  • Nausea gravidarum
  • Nausea

Symptoms of Morning Sickness

Nausea during pregnancy which may or may not be accompanied by vomiting.

Causes of Morning Sickness

  • Some women are sensitive to the hundredfold increase in the hormone estrogen circulating in their blood.
  • Progesterone also increases which relaxes the smooth muscles of the uterus as well as the smooth muscles of the stomach and intestines resulting in excessive amounts of stomach acids which leads to heartburn, or gastrointestinal reflux.
  • Hypoglycemia, or low blood sugar, may be to blame for nausea and/or vomiting in pregnancy due to the placenta taking energy from the expectant mother.
  • A sudden increase in the pregnancy hormone, HCG (human chorionic gonadotropin), may inevitably cause nausea.
  • Increases in the hormone cholecystokinin causes slowed digestion in order for more efficient nutrient absorption to take place both for the mother as well as the growing fetus.
  • Perhaps as a built-in defense mechanism against harmful substances, pregnant women tend to experience an increase in sensitivity to odors, which therefore over stimulates the nausea center of the brain.

Risk Factors of Morning Sickness

  • A pregnant woman may be at risk for pregnancy-related nausea if she has ever experienced any of the following prior to the current pregnancy: motion sickness, migraines, sensitivity to certain smells or tastes, sensitivity to estrogen in birth control pills, or she has experienced morning sickness during a previous pregnancy
  • An expectant woman may also be at risk for morning sickness if she is pregnant with more than one fetus.

Complications of Morning Sickness

Complications that could jeopardize the pregnancy may arise as a result of more severe morning sickness, hyperemesis gravidarum, and include the following:

  • Dehydration
  • Malnutrition
  • Weight loss
  • Alkalosis
  • Hypokalemia
  • Acid reflux
  • High blood pressure

  • Expose yourself to the smell of freshly cut citrus fruits such as lemons.
  • Accommodate food cravings (things you want) and aversions (things that aggravate your morning sickness) when possible.
  • Pregnant women tend to crave or get nauseated by things typically because their bodies are telling them what they need or what they need to avoid in order to have a healthy pregnancy outcome.
  • Consume fruits and vegetables with a high water concentration such as tomatoes, melons, citrus fruits, strawberries, leafy vegetables, and grapes.
  • Try the BRATT diet to keep your stomach settled. The BRATT diet is simply made up of bananas, rice, applesauce, toast and tea.

  • Rest as often as humanly possible!
  • Avoid getting overheated which exacerbates pregnancy nausea.
  • Try to work in some light exercise such as walking and/or swimming, but don’t over do it.
  • Avoid laying down immediately after eating. Try to allow 2-3 hours after eating to avoid stomach upset caused from acid.

Testing and diagnosis for Morning Sickness

There are no specific tests available to diagnosis morning sickness in itself due to the fact that morning sickness is merely a symptom of pregnancy. On that note, a positive pregnancy test may tell a woman the cause of the nausea and/or vomiting she has been experiencing.

However, sever morning sickness known as hyperemesis gravidarum, or HEG, may require further testing in order to rule out other complications in the pregnancy.

Further testing may include the following:

  • Amylase
  • Blood calcium level
  • Serum electrolytes, which can show low potassium or sodium levels in blood. Low levels can mean dehydration or acid-base imbalance.
  • Hematocrit, part of a blood count, which may become high due to dehydration
  • Liver enzymes and bilirubin
  • Urinalysis for ketones and specific gravity. Ketones are a sign of starvation. Specific gravity can show dehydration.
  • An ultrasound may also be done to check the condition of the baby and the womb.
  • If a woman has abdominal pain or vomits blood, the doctor may do an endoscopy. This is a test where a small tube is passed through a woman’s mouth and throat down to her stomach. The tube has a light at the end, which helps the doctor to look for problems in the stomach.
  • Serum for hepatitis testing
  • Liver function tests
  • Ultrasound to look at gallbladder
  • Urinalysis and culture to test for bacteria
  • Ultrasound to look for twins or a tumorous growth of the placenta

Treatment Options for Morning Sickness

Herbal & Home Remedies
