Every pregnancy is different and every pregnant woman will experience a different pregnancy journey.

About half to two thirds of all pregnant women will experience nausea, especially in the first trimester.
For most women, pregnancy nausea starts around the fourth week of pregnancy and gets better by 12 to 14 weeks.

There is no single definite cause of nausea during pregnancy, and its severity varies among pregnant women. However, there are several risk factors that contribute to nausea and vomiting during pregnancy such as:

1. Hormone Changes

Research suggests that nausea and vomiting during pregnancy may be due to the effects of a hormone produced by the placenta called human chorionic gonadotropin (HCG). Pregnant women start producing HCG as soon as the fertilized egg attaches to the uterine lining.

In addition, the hormone estrogen also slows down transit time and gastric emptying through nitric oxide-mediated mechanisms, which may further contribute to the phenomenon. morning sickness and nausea. Progesterone can also do the same.

2. Blood Sugar

Under normal conditions, various hormones work to keep blood sugar levels under control. However, during pregnancy, hormone levels change, making it harder for the body to process blood sugar efficiently.

Hyperglycemia (increased blood sugar levels) or hypoglycemia (blood sugar levels that are too low) can cause nausea.

3. Blood Pressure Fluctuations

As pregnancy progresses, her blood pressure can undergo changes. There are several possible causes, one of which is the increasing amount of blood in the body of pregnant women.

According to the journal Circulation, pregnant women’s blood volume will increase by as much as 45 percent during pregnancy which is the extra blood that the heart must pump throughout the body.

The left ventricle (the left side of the heart that pumps a lot) will become thicker and larger. This temporary effect allows the heart to work harder to support the increased blood volume, thereby increasing blood pressure.

In early pregnancy, usually from 5 weeks to the middle of the second trimester, the blood pressure of pregnant women tends to decrease. This is because pregnancy hormones can stimulate blood vessels to dilate.

Both high and low blood pressure can cause dizziness, nausea, and vomiting.

High blood pressure during pregnancy is defined as a systolic of 140 mm Hg or higher, with a diastolic of 90 mm Hg or higher, while there are no definitive figures for blood pressure that is too low.

4. Changes in Body Metabolism

The body will burn more calories during pregnancy due to increased body weight and surface area. Basically, the body must burn calories to keep the heart pumping, brain function, blood flow, and muscles working. It also contributes to a risk factor for morning sickness.

5. A Sensitive Sense of Smell

Many pregnant women experience changes in the sensitivity of their sense of smell during the first trimester. Experts consider that for some pregnant women, this increased sense of smell can trigger morning sickness.

This increased sense of smell occurs as a result of olfactory hyperacuity induced by the hormone estrogen, which increases during pregnancy.

1. Pay attention to food intake

Fatty and spicy foods and caffeine can increase the chances of triggering the release of stomach acid, especially as pregnancy progresses and the fetus pushes against the digestive tract.

Eating small meals can help reduce the chance of vomiting but keep the stomach full. An empty stomach can make nausea worse because the stomach produces acid, but there is nothing to digest, except the stomach lining. This can trigger nausea.

At breakfast, eat apples, pears, bananas, or citrus fruits in addition to help you feel full earlier. Potassium contained in the fruit can help prevent morning sickness.

You can also eat cold or cold food to reduce the smell of food that can trigger nausea and vomiting.

In the evening, having a high-protein snack before bed will help regulate blood glucose levels at night, thereby reducing nausea and vomiting.

2. Maintain Fluid Intake

It is important to stay hydrated for good health, especially during pregnancy. When you vomit, fluid intake can also come out.

It can be difficult to drink 8 glasses of water a day when you have nausea, but dehydration can make nausea worse. Drink water by adding apple cider vinegar and honey to the water to make it more palatable.

Drink ginger tea or tea peppermint to help soothe the stomach. Ginger has long been used to aid digestion and reduce stomach discomfort. Studies show that ginger can also help relieve symptoms of nausea in pregnant women.

3. Lots of Rest

When pregnant. Adequate sleep is a must. Go to bed early and wake up early. Napping during the day can also help, but shouldn’t be taken immediately after eating as this can increase nausea.

When night falls, try not to be exposed to light, both from lights and gadgets to help the body rest better and get quality sleep.

As time goes on and the tummy gets bigger, a maternity pillow can help provide comfort to the back and tummy. Do not use sleeping pills unless prescribed by a doctor.

4. Take Pregnancy Supplements

Supplements should only be used under a doctor’s supervision. If you are taking vitamins, the best time to take them is before bed.

Vitamin B6 can help reduce nausea. You can ask your doctor for a prescription if you feel nausea and vomiting are enough to interfere with your daily activities.

Iron supplements prescribed during pregnancy can sometimes cause nausea. Your doctor may recommend a slower-release supplement or a lower dose.

Take iron supplements with orange juice or other drinks with vitamin C to increase absorption.

When to see a doctor?

Excessive vomiting during pregnancy is known as hyperemesis gravidarum. This condition can lead to dehydration, malnutrition, and weight loss.

Hyperemesis occurs in 1 in every 300 women during pregnancy, and usually only occurs during the first 20 weeks of pregnancy.

See a doctor immediately if you experience:

  • Vomiting blood, which may be red or black
  • Vomiting more than four times in one day
  • Unable to eat or drink at all for more than a day
  • Drastic weight loss

Your doctor may recommend dietary changes, plenty of rest and the use of antacids. In severe cases, hyperemetic patients may need to receive fluids and nutrition intravenously.
