What Causes Morning Sickness During Pregnancy


Morning sickness is a common symptom of pregnancy that affects most women to some degree. It typically begins around 5-6 weeks of pregnancy and it is estimated that about 70 percent of pregnant women experience some degree of morning sickness. Despite its name, morning sickness can actually occur at any time of day. It is sometimes accompanied by other symptoms like dizziness, nausea, exhaustion and poor sleep.

So what exactly causes morning sickness during pregnancy? The exact cause remains unknown, however there are a number of factors believed to contribute to it. Research suggests that hormone shifts play a key role in causing morning sickness. During the early stages of pregnancy, rising levels of hormones like estrogen and progesterone can cause changes in digestive function which can then lead to feelings of nausea. Additionally, lower glucose levels have been linked to nausea in some cases as well as stress or fatigue, dietary factors and increased sensitivity to smell or odors.

Causes of Morning Sickness During Pregnancy

Hormonal Changes: Many pregnant women experience nausea during the earliest stages of their pregnancy due to rapidly changing levels of hormones such as estrogen, progesterone and human chorionic gonadotropin. These hormones are responsible for the nourishment and growth of the fetus, and typically begin to surge soon after conception. As the body adjusts to these changes, some people find themselves experiencing symptoms of morning sickness.

Changes in Metabolism: Metabolism naturally accelerates during pregnancy as the body adjusts to diet and nutrient requirements with an increased demand for glucose, vitamins and minerals by the fetus. This can cause intense hunger pangs or excessive fullness, making it difficult to find foods that satisfy or easily digestible foods that don’t trigger symptoms of nausea and vomiting.

Food Aversions: Although food cravings are often associated with pregnancy, they could also be accompanied by extreme aversions to certain smells or even whole categories of food (i.e. vegetables) which can lead to GI problems including limited appetite and bouts of nausea throughout the day.

Psychological: Some medical professionals suspect an emotional response also plays a role in having morning sickness due to heightened stress reactions during pregnancy. When faced with new roles or responsibilities associated with motherhood along with physical changes experienced through pregnancy, anxiety may worsen existing gastro intestinal problems leading to more frequent episodes of nausea throughout the day.

Environmental Factors: Smells from different sources in our environment like perfumes, food preparation ingredients and garbage can all cause feelings of nausea due to their intensity and chemical composition causing over-sensitivity in pregnant women’s bodies. Additionally, triggers like motion sickness (car rides), medications, alcohol consumption teratogenic substances must be avoided at all times during this fragile state when feeling nauseous seems unavoidable

Symptoms of Morning Sickness During Pregnancy

Common symptoms of morning sickness during pregnancy include nausea, vomiting and fatigue. Nausea can occur with or without vomiting and is most noticeable in the morning, but can also come and go throughout the day. Vomiting may happen regularly, in some cases up to several times a day. Fatigue accompanies these symptoms since they are energy-sapping. Other less common symptoms may include lower back pain, dizziness, irritability, indigestion, constipation or diarrhea and heartburn. Some women also report food aversions or cravings during this time. Women who experience HG (hyperemesis gravidarum), which is extreme nausea and vomiting that requires medical intervention, may exhibit additional signs such as dehydration, electrolyte imbalance (too high or too low), fainting spells and confusion.

Treatment Options for Morning Sickness During Pregnancy

Over-the-counter medications such as antihistamines, antiemetics, and antacids can help with the symptoms of morning sickness. Several prescription medications may also be prescribed including promethazine, olanzapine, prochlorperazine, and metoclopramide.

Dietary changes that can help alleviate the symptoms of morning sickness include drinking lots of fluids and avoiding certain trigger foods like spicy meals or acidic fruits. Eating five to six small meals throughout the day may also help control nausea. Taking vitamin B6 supplements has been linked to reducing morning sickness in many women.

Herbal remedies like ginger root tea and acupuncture may also be used to treat morning sickness during pregnancy. Ginger teas or candies have been shown to reduce nausea; in some cases it can even eliminate the need for medication. Acupuncture is another option that is becoming more popular as an alternative treatment for morning sickness because it is thought to decrease nausea by stimulating pressure points in the body associated with nausea relief.

How to Cope With Morning Sickness During Pregnancy

Morning sickness, otherwise known as nausea and vomiting of pregnancy (NVP), is a common symptom of pregnancy. It typically begins around the fifth week of pregnancy and can last through the first trimester or even until birth. The exact cause isn’t known, but there are several factors associated with morning sickness—including hormonal changes such as an increase in estrogen levels and hCG, the pregnancy hormone. An increase in blood flow to the uterus may also put pressure on the stomach leading to nausea and vomiting. Additionally, fatigue or emotional stress can also lead to the onset of morning sickness.

In order to cope with morning sickness during pregnancy it’s important for pregnant women to take care of their physical and mental health. Pregnant women should aim for smaller, more frequent meals since eating large amounts may worsen nausea. Consuming foods that are known triggers—such as spicy or fatty meals—should also be avoided when possible. It’s also critical that pregnant women get adequate sleep each night and practice self-care such as yoga, meditation, massage therapy or spending time outdoors in nature. These strategies help reduce stress levels and can make a huge difference in how you feel each day. And finally, don’t be afraid to ask for support from family members or close friends if you need a helping hand!

Wrapping Up

Morning sickness is a very common symptom experienced by pregnant women. Although the exact cause of morning sickness is unknown, experts believe it is due to the hormones released during pregnancy which lead to changes in the body and an increased sense of smell. Some helpful tips to assist with morning sickness include: eating smaller meals more frequently throughout the day; avoiding foods that are strong-smelling; staying hydrated; and getting plenty of rest. However, if symptoms persist or become worse over time, it’s important to seek medical advice from your doctor or midwife.
