8 Major Causes of Vomiting During Pregnancy

Vomiting during pregnancy, often known as morning sickness, is a common and sometimes challenging symptom many women experience during pregnancy. It usually happens in the first trimester but can last longer for some. The severity ranges from mild nausea to intense vomiting and dehydration, known as hyperemesis gravidarum. Although the exact reason is unknown, hormone fluctuations and noticeably elevated levels of estrogen and human chorionic gonadotropin (hCG) are thought to be involved. 

In this article, we will explore 8 major causes of vomiting during pregnancy, shedding light on why they occur and how they can be addressed to ensure a healthier and more comfortable pregnancy journey.

What Causes Emesis In Pregnancy?

Nausea and morning sickness are common phenomena during pregnancy. It is a multifaceted phenomenon influenced by various biological and environmental factors. Although its exact causes are not entirely elucidated, several fundamental mechanisms are believed to contribute to emesis during pregnancy:

1. Hormonal Fluctuations

Dynamic changes in hormone levels, notably the surge in human chorionic gonadotropin (hCG) and estrogen, are pivotal in triggering morning sickness. These hormonal shifts impact the gastrointestinal tract and interact with the central nervous system, affecting the brain's areas responsible for regulating nausea and vomiting.

2. Heightened Sensitivity to Odours

Pregnant women frequently report an increased sensitivity to odours, with certain smells triggering feelings of nausea and vomiting. This heightened olfactory sensitivity may stem from hormonal alterations or other physiological adaptations during pregnancy.

3. Gastric Acid Secretion

Pregnancy is associated with elevated gastric acid secretion, potentially leading to increased stomach acidity. Higher levels of stomach acid can contribute to gastrointestinal discomfort and nausea, mainly when the stomach is empty or during periods of prolonged fasting.

4. Psychological And Emotional Factors

Stress, anxiety, and emotional upheaval can exacerbate symptoms of morning sickness. The psychological strain associated with pregnancy, coupled with the anticipation of childbirth and parenthood, may influence the frequency and severity of nausea and vomiting episodes.

5. Glycemic Variability

Fluctuations in blood sugar levels, especially when skipped meals or intervals between eating are prolonged, can provoke nausea and vomiting. Maintaining stable blood glucose levels through regular, balanced meals and low-calorie snacks can help mitigate these symptoms.

6. Genetic Susceptibility

Emerging evidence suggests that genetic predispositions may contribute to an individual's susceptibility to morning sickness. Women with a family history of severe nausea and vomiting during pregnancy may have a higher likelihood of experiencing similar symptoms themselves.

7. Physiological Changes In The Digestive System

Pregnancy induces various alterations in the digestive system, including slowed gastric emptying and relaxation of the stomach muscles. These physiological adaptations may contribute to feelings of gastrointestinal discomfort and nausea.

8. Multiparity

Women carrying multiple fetuses, such as twins or triplets, often experience more pronounced symptoms of morning sickness. The increased hormonal load associated with numerous pregnancies can intensify nausea and vomiting.

Dietitian’s Recommendation

As a dietitian, I recommend frequent, small meals to prevent an empty stomach, which can worsen nausea. Choose easily digestible foods like crackers, toast, or plain rice. Incorporate ginger, known for its anti-nausea properties, into your diet through ginger tea, ginger ale, or ginger candies. Avoid spicy, greasy, or intensely flavoured foods and those with strong odours. Stay hydrated by sipping fluids throughout the day, but avoid drinking during meals. Experiment with different foods to find what works best for you.

The Final Say

In summary, vomiting during pregnancy, or morning sickness, is influenced by various factors such as hormonal changes, sensitivity to smells, increased stomach acid, and emotional stress. Genetic predispositions may also play a role. While understanding its exact causes remains incomplete, recognising these diverse factors highlights the complexity of managing symptoms. Despite its discomfort, morning sickness is a common aspect of pregnancy, manageable with personalised care and support.                                                                                        

FAQs

1. How can we manage extreme vomiting during pregnancy?

Extreme vomiting during pregnancy requires medical intervention, including anti-nausea medications, IV fluids, and nutritional support. Prompt medical attention is essential for managing severe symptoms and ensuring the health of both mother and baby.

2. Is it okay for a pregnant woman to throw up?

It is normal for pregnant women to vomit, especially in the first trimester. However, medical advice should be sought if it's severe or persistent.
