Frequent sneezing, runny nose and cough in pregnancy
Medical expert of the article
Last reviewed: 05.07.2025

Sneezing during pregnancy does not have any special distinguishing features from sneezing in an ordinary person. The causes and symptoms are very similar, whether it is a pregnant woman or a child. But when it comes to approaches to treatment, pregnancy is a special condition that you should take into account even with the most common illness. Here is why you need to know about it.
Causes sneezing during pregnancy
It is important to note that sneezing is the most common protective symptom created by nature. This reflex is expressed in every person, and it helps to provide the highest level of protection of our respiratory tract from various mechanical and biological irritants. When an irritant gets into the upper respiratory tract, meaning the nasopharynx or nasal cavity, the nerve fibers immediately react to it. These fibers are in the mucous membrane, and their main function is to perceive such irritations. Under normal conditions, there are small cilia on the epithelium in the nasal cavity, which do not allow all bad bacteria or dust particles to pass through. But when there are many pathogens, the cilia do not fully cope with this function. Or the function of the cilia can be reduced after an illness, for example, after rhinitis. Therefore, it is immediately necessary to identify a risk factor - this is a previous illness of the upper respiratory tract. So, when pathogens do get on the mucous membrane, the neurons immediately perceive this and send a signal about this to the structures of the brain. In fact, the brain does not even have time to "think" about sneezing, because it would take a lot of time. Therefore, the information is processed not at the level of the brain itself, but at the level of reflex connections with which each person is born. Therefore, the pathogenesis lies precisely in the sneezing reflex, which is developed in each person.
The main purpose of the sneeze reflex is to eliminate a foreign body from the respiratory tract in order to protect the lower respiratory tract.
Therefore, the main reason for sneezing in all people is the entry of a foreign agent into the mucous membranes. But sneezing can also be caused by a disease, and in pregnant women this reason is more common, simply because they are more susceptible to various diseases.
Among the pathologies that cause sneezing, infectious and allergic causes can be distinguished.
Infections can be caused by viruses (flu virus, adenoviruses, rhinoviruses ), which is more common, but can also be caused by bacteria. When a virus gets on the mucous membrane, it also causes irritation and sneezing. This can be the first manifestation even before other symptoms develop. The virus multiplies at the site of entry, in this case, in the upper respiratory tract, which subsequently causes detachment of epithelial cells and rhinorrhea. Constant irritation of the nasal cavity during rhinitis during the course of the disease is the cause of sneezing.
Seasonal or year-round allergies can be the cause or even a symptom of sneezing. When an allergy occurs to flowering plants, then the symptoms bother exactly during the period when these plants bloom. But also, an allergy can be not only to flowering, but to pollen, to the petals of the plant itself, or to household irritants, then the allergy bothers all year round.
Pathogenesis
The pathogenesis of allergic diseases is associated with the release of excess histamine. This is a substance that is released from cells under the influence of an allergen. Histamine is able to dilate blood vessels at the site of action, it promotes the secretion of cells, thus, the symptoms of allergic rhinitis develop. Such constant irritation against the background of histamine is the main cause of sneezing, and at the same time a symptom of allergy.
Sneezing as a sign of pregnancy is not quite the same thing. After all, it is not a symptom at all, since it is not related to the pregnancy process. Pregnant women, especially in the first trimester, are simply more sensitive to various irritants, and they may sneeze more often. But if a woman begins to sneeze more often, this does not mean that you are expecting a child.
There is a nuance that needs to be taken into account. In the third trimester of pregnancy, when the fetus is quite large, it often happens that the mucous membrane of the nasal cavity swells and there is a feeling of nasal congestion without symptoms of infection. In this case, there may be sneezing. But this symptom is very dangerous, especially if the woman has high blood pressure. This can be one of the symptoms of a threatening condition - preeclampsia. Therefore, the duration of pregnancy and your well-being play a huge role, even with the appearance of such an insignificant symptom as sneezing.
Symptoms sneezing during pregnancy
Sneezing during pregnancy is a symptom of illness when there are other manifestations. When it comes to a simple viral disease, sneezing can be one of the symptoms that appear first.
The first signs of a viral infection may begin with sneezing. When a huge amount of the virus gets on the mucous membrane, and they begin to increase in number, this happens in the epithelial cells. At the same time, the neural endings are irritated, which causes mechanical irritation and sneezing, as a protective reflex. This can eliminate a certain number of viruses, but they have already begun to multiply. Therefore, other symptoms of the disease develop further - nasal congestion, discharge, runny nose and sneezing during pregnancy, which is dangerous in the early stages. Sneezing during pregnancy in the early stages is dangerous if it is a symptom of a viral infection, since it is during this period that the child is very vulnerable. All organs and systems are being laid down, and therefore any virus at this time can be very dangerous. And when sneezing appears in the early stages, you need to be wary of the manifestation of infection. Therefore, it is already necessary to take preventive measures.
Coughing and sneezing during pregnancy are more serious symptoms that indicate possible damage to the lower respiratory tract. A simple viral infection, which could start with sneezing, can lead to the inflammatory process not being limited to the upper respiratory tract. In this case, pathogens will penetrate the lower respiratory tract, causing inflammation of the bronchi - bronchitis. Cough is precisely a symptom of the development of bronchitis. This is a more serious condition, because in such cases bacteria can often join the viruses, which requires other, more aggressive treatment.
Allergic sneezing during pregnancy is easy to identify, because it occurs after contact with an allergen. Then, in addition to sneezing, other symptoms appear. There is swelling under the eyes, lacrimation, nasal discharge is mucous in nature, or there may simply be nasal congestion. But the main distinguishing feature is still the appearance of symptoms after contact with an allergen.
What are the consequences and complications of sneezing in pregnant women? Is sneezing dangerous and harmful during pregnancy? An infectious disease can be dangerous if it is complicated by a bacterial infection, such as bronchitis or pneumonia.
If we are talking about allergic sneezing, then during pregnancy, women become more sensitive to the action of allergens. Therefore, simple allergic rhinitis can even be complicated by the development of an asthma attack.
A sharp sneeze during pregnancy causes active contraction of the diaphragm and abdominal muscles. At the same time, pain may occur when sneezing in the lower abdomen, in the area of the ovaries during pregnancy, which may seem like a threatening factor for the child. But if the pregnancy is stable, then you should not worry.
Frequent and strong sneezing during pregnancy in the third trimester can lead to such unpleasant things as involuntary urination. In fact, urinary incontinence when sneezing during pregnancy can be easily explained. When the uterus is significantly enlarged in size, it presses on the bladder. At the same time, the sphincter cannot work so actively, and with such a strong effort during sneezing, it can relax. This leads to such an unpleasant phenomenon. How to sneeze correctly during pregnancy to avoid such phenomena? First, you should not do it so abruptly. You need to relax, then sneeze, but without holding back the effort in yourself.
Can sneezing harm pregnancy if the cause is not infectious? Theoretically speaking, if the pregnancy is healthy, then sneezing will not affect it in any way. But if there is a pathology of pregnancy, for example, placenta previa, then any excessive force can cause premature birth. Only in this case, theoretically, sneezing can harm.
Diagnostics sneezing during pregnancy
Diagnostics is not particularly difficult. If there are other symptoms besides sneezing, then this may be due to a viral infection or an allergy. Differential diagnostics of a viral infection is not difficult. And if there is an increase in body temperature, then this is clearly not an allergic cause of sneezing. Considering that there is pregnancy, then diagnostics should always be complete. Therefore, you cannot self-medicate and you should always consult a doctor.
General tests should be performed for women, which include a general blood test and a general urine test. This will help to exclude bacterial inflammation. Additional tests are performed if necessary. As a rule, if we are talking about a simple viral disease, then monitoring of the fetus is not performed if there are no complaints. Just routine examinations are performed. Instrumental diagnostics can be used to monitor the fetus if the woman has complications or a problematic pregnancy. Then an additional ultrasound examination or cardiotocography of the fetus may be performed.

Treatment sneezing during pregnancy
There is no treatment for sneezing as a symptom of a disease. It is important to first establish the cause and, based on this, use medications that are approved for pregnant women.

Prevention
Prevention of sneezing in pregnant women should be especially thorough, since women in this position are especially vulnerable. Pregnant women are more prone to allergic reactions, so sneezing may be associated with this. Therefore, preventive measures are recommended for pregnant women. It is necessary to use frequent wet cleaning with hypoallergenic products. It is also necessary to use hypoallergenic hygiene products. It is very important to eat healthy food with a high content of vegetables and fruits, which provides the body with vitamins. It is also necessary to prevent colds by avoiding contact with infectious patients.
Forecast

Sneezing during pregnancy is not always a harmless symptom, sometimes it is the first manifestation of an infectious disease. The second reason for frequent sneezing can be an allergic disease. Therefore, before starting treatment, you need to find out the cause, and then decide on treatment methods that will not harm the baby.
