It’s not a secret that many pregnant women experience dizziness. For some of them it is insignificant, and for others, on the contrary, strong and, sometimes, results in fainting. Is dizziness a sign of pregnancy? Why does it happen? Doctors say that this symptom of toxicosis is not as dangerous as, for example, vomiting. Nevertheless, it is useful for a pregnant woman to know why this happens and how to deal with dizziness.
Is Dizziness a Sign of Pregnancy?
As you may know, the very first symptoms of pregnancy and its main signs are manifested in the first few weeks after the conception. Thus, a woman may understand whether pregnancy has occurred or not.
Indeed, dizziness or fainting can be one of the early signs of pregnancy. However, not always these signs mean that you are pregnant. Dizziness or fainting can also be a manifestation of a serious illness.
At the same time, it is interesting that almost 8-10% of women do not suspect about their pregnancy, and it is nausea and dizziness in their case that is a kind of an alarm sign and a reason for buying a pregnancy test.
At the same time, many doctors say that the fact that dizziness is a sign of pregnancy is a fairly common misconception, although not groundless. So, is dizziness a sign of pregnancy? In fact, for a normal pregnancy, with the correct rhythm of life, the occurrence of dizziness and fainting is not absolutely necessary.
Dizziness during Pregnancy
The opinion that dizziness is a sign of pregnancy has a scientific basis. However, this does not mean that this is true for all pregnant women. During pregnancy, there are a number of changes in the blood supply system:
- increase of the vasculature in the small pelvis;
- redistribution of blood – the blood supply of the uterus significantly increases. In a non-pregnant woman, the uterine blood flow accounts for about 2% of the total blood volume. By the end of pregnancy it is more than 20-30%.
These physiological mechanisms at the beginning of pregnancy are not yet perfect and do not always compensate for the increased needs of the body. Therefore, periodically, there may be deterioration in the blood supply of the brain and developing in response to this hypoxia of its tissues. This is manifested by dizziness, and sometimes fainting.
Dizziness may be a symptom of the toxicosis of the first half of pregnancy. It may also manifest as weakness, nausea and vomiting. When vomiting occurs, there is dehydration of the body. It leads to a decrease in blood volume and to deterioration in the supply of blood to the brain.
In the second half of pregnancy, the damage of the blood supply to the brain due to the increase in the size of the uterus is also possible. Large venous vessels are squeezed, thereby reducing the flow of blood to the heart (especially in the prone position). Therefore, a sharp transition to a vertical position causes a temporary decrease in the flow of blood to the brain and to internal organs.
Is Dizziness a Sign of Pregnancy or a Symptom of a Disease?
Dizziness can indeed be a sign of pregnancy. At the same time, even more often dizziness is a symptom of a disease. In general, dizziness is the feeling that the space around you is moving or the body is moving in space. If these feelings arise in a future mother only after sudden changes in the position of the body, then this is normal. There is nothing to be afraid of, but only if dizziness is weak and short.
The fact that dizziness is a sign of pregnancy does not mean that such a state can be ignored. To avoid falling and possible injury (which can be very dangerous for the embryo and for the future mother), the woman should sit down and, even better, lie down. This will allow blood to enter the brain in the required quantity and normalize the state of health.
The Main Causes of Dizziness
Usually dizziness is harmless and occurs in many people without visible signs. There can be various reasons for this.
The most common reason is the violation of vascular tone in the brain. It happens when stagnation of blood occurs in excessively dilated, or, conversely, too narrowed vessels. This can lead to thrombosis. The rate of blood flow is significantly reduced and a certain amount of oxygen enters the brain. But this amount of oxygen is not enough for proper nutrition of the brain.
This problem even before pregnancy causes troubles while travelling by different types of transport. A person may suffer from high sensitivity to temperature changes and loss of balance with sudden movements. During pregnancy these ailments aggravate. Now they cause not only discomfort, but also significant health problems.
It is important not to ignore such symptoms and respond to them correctly and without panic. If you feel dizziness and nausea, lie or at least sit down. These positions contribute to forced blood flow to the head and improves well-being.
The main causes of dizziness:
- low blood pressure;
- low hemoglobin level in the blood;
- cervical osteochondrosis;
- cold, flu;
- head injury;
- circulatory disturbance in the brain;
- taking certain medications;
- alcohol abuse;
- Meniere’s disease.
Low blood pressure can also be a cause of dizziness. Do not ignore this problem.
Dizziness associated with anemia or poor irregular eating can be caused by a fall in blood sugar levels. A woman in this case should avoid malnutrition. Eat 4-5 times a day, without waiting for a feeling of hunger, but meals should not be big. Be sure to consult a doctor and start a full treatment. This must be done to prevent problems with your own and your baby’s health.
Natural Causes of Dizziness
It happens that a slight dizziness may appear after a change in body position or a sharp rise in every person. Women during the first and the second trimester are not an exception. What’s more, in the early stages of pregnancy lack of oxygen may also cause dizziness. The reasons for this are different:
- Sometimes there is simply not enough fresh air in the room. In that case, everything is simple. It is necessary to open the window and help the pregnant woman to free herself from the tight collar or the outer clothing restraining the breathing.
- In the second case, oxygen does not flow to the brain and the reasons are hidden. Most likely, pregnancy itself has nothing to do with it. The reason may be a disease of an ischemic nature, a vascular system or cervical osteochondrosis.
When we feel dizzy, it seems that things are spinning around, and the ground is running out from under the feet. It doesn’t differ from the feeling of dizziness in pregnant women at 35, 38 or 39 weeks. And if usually this condition is harmless, then in the future mothers it can cause anxiety.
Most often in later terms, the head is spinning because of the weakened tonus of the vessels of the brain. The organism is quite naturally “exhausted” by the 35th week, not to mention 38-39 weeks and beyond. In addition, already in the early stages of pregnancy, blood pressure starts to rise and fall. It leads to possible spasm or the formation of blood clot in the vessels.
Some women naturally have underdeveloped vestibular system. They do not know what to do during the slightest shake or pitching and have an increased sensitivity to atmospheric pressure. During pregnancy everything can become worse. A woman often experiences a loss of balance by the 35th week. By the 38th and 39th week a future mom may refuse traveling by any transport and practically does not go out. It is important to prevent such causes in time, before pregnancy begins. If there was no such an opportunity, it is still not a reason to panic.
How Dangerous Is Dizziness during Pregnancy?
If dizziness during pregnancy doesn’t occur often and is caused by external reasons – heat, stuffiness, hunger, nervous tension, fright, sharp movement, then you should not worry. The only danger of such dizziness is that a woman can suddenly lose consciousness. This can happen unexpectedly to others and cause unpleasant consequences in the form of bruises, abrasions, etc.
Severe dizziness during pregnancy, accompanied by fainting, profuse sweating, ringing in the ears, trembling, black dots in the eyes may be a symptom of various diseases in which a woman needs medical help, often immediate. Therefore, when there is dizziness during pregnancy, it is necessary to consult a doctor in any case. The doctor will prescribe tests and find out the cause of the trouble.
To avoid dizziness in pregnancy, follow the simple rules:
- Avoid sudden movements;
- During sitting or standing, change the position more often;
- Eat more often, do not wait until you feel hunger (it would be nice to always have a snack along);
- Try to avoid places with large crowds of people;
- Air the room more often;
- Do not neglect moderate sport activities;
- Take a contrast shower.
