Pregnancy Without Morning Sickness First Trimester
Pregnancy Without Morning Sickness First Trimester: Morning sickness is one of those topics that gets thrown around in casual conversation as something that everyone has experienced or knows someone who has experienced. Most people have an opinion on how bad it can be, what causes it, whether there are any remedies for it, etc., but most don’t really understand why it happens in the first place. In this article we’ll discuss some theories about why pregnancy without morning sickness might not be such a great thing after all.
First off, let’s start by talking about what exactly does cause nausea? Nausea occurs because our bodies produce hormones called “medullary thyroid hormones” (also known as thyroxine). These hormones regulate several important functions including metabolism, growth and development, energy production, nervous system function, muscle contraction, heart rate, blood pressure and temperature regulation [Source: Mayo Clinic].
A disruption in these hormone levels results in nausea — which makes sense since they also help control appetite! But why do pregnant women experience less nausea than non-pregnant women? The answer lies in another set of hormones produced by the placenta called “prostaglandins.” Prostaglandin F2 alpha stimulates contractions of smooth muscles throughout the body, especially within the gastrointestinal tract where they play a role in stimulating gastric emptying and intestinal peristalsis [Source: WebMD].
During pregnancy, prostaglandins are increased dramatically due to the fact that the uterus must grow larger to accommodate a growing fetus [Source: Pregnancy Without Nausea]. This increase in prostaglandins explains a lot! If you’ve ever had diarrhea while pregnant, then you know just how much work the digestive system needs to get done every day. And if you’re like me, you probably already knew that getting sick from food poisoning isn’t nearly as fun as experiencing pregnancy sickness. But did you know that the same type of prostaglandins responsible for triggering nausea and vomiting could be responsible for making you feel better after eating too spicy chili peppers?
That’s right, prostaglandins may actually be used by the immune system to aid in healing wounds [Source: Medical News Today]. So, naturally occurring prostaglandins can trigger both nausea AND reduce pain…weird, huh?!
Now that we’ve established what causes nausea, let’s talk about the difference between normal nausea and severe nausea. Normal nausea usually starts in the second trimester and lasts until delivery. Severe nausea usually begins in the first trimester and continues into the third and sometimes even the fourth depending upon the severity of the symptoms. One major symptom of severe nausea is frequent urination. Frequent urination is caused by fluid buildup in the stomach which puts pressure on the bladder causing frequent urges to urinate. Other common symptoms include dizziness, fatigue, weight gain, headaches, constipation, dry mouth, exhaustion, backache, gas pains and general discomfort [Source: NetDoctor].
So now that we’ve discussed what causes nausea, let’s talk about why having no morning sickness doesn’t mean everything is fine with your pregnancy. Many women report being so relieved to hear that their pregnancy is completely normal that they don’t go to see a doctor for fear of hearing words that will confirm their worst fears. However, a healthy pregnancy should never be considered abnormal. Some women simply have more nausea than others, and that’s OK! There are many other factors that determine how well you tolerate pregnancy, such as genetics, diet, environment, emotional state, stress, nutrition and overall health.
One study found that certain foods affected the intensity of nausea differently amongst participants. For example, citrus fruits (such as oranges) were associated with reduced nausea compared to bananas [Source: Journal of Nutrition Education and Behaviors] so make sure to stay away from the fruit that seems to give you the most trouble! Also, try to eat smaller meals throughout the day rather than three large meals spaced apart by hours.
Eating frequently helps keep digestion moving smoothly along, reduces feelings of hunger pangs and keeps blood sugar regulated [Source: Health Lifestyles]. Finally, avoid alcohol consumption and smoking cigarettes to decrease the effects of nicotine withdrawal on mood and nausea. Nicotine increases the release of dopamine in the brain, which triggers nausea [Source: Science Daily].
In conclusion, it’s important to remember that pregnancy is perfectly normal and nothing should be considered abnormal unless complications arise. Your doctor is trained to identify problems before they become serious issues, so always consult him/her if you notice anything unusual during your prenatal visits.
