Sneezing is a very common action in our daily life. Pregnant women are normal human beings and sneeze too, sneezing can cause an increase in abdominal pressure, which in turn may cause abdominal pain and bleeding, and should be taken with a certain degree of seriousness. There are three main reasons that cause pregnant women to sneeze, one is allergy, the second is rhinitis, and the third is cold. 1, allergy: in the whole population, allergy is not a lot of people, after pregnancy, under the action of estrogen and progesterone and other hormones, it may be aggravated. 2, pregnancy rhinitis: this is the most common cause of sneezing after pregnancy, the symptoms are somewhat similar to allergies. After pregnancy, under the action of estrogen and progesterone, the capillaries in the nasal cavity will be swollen and congested, and will secrete a lot of mucus. At this time, your nasal cavity will be sensitive to a lot of external substances, and will be prone to allergy-like reactions, and you will have sneezing, stuffy nose and runny nose, and even a headache. When you are not pregnant, your nose may be allergic to certain external substances, but after pregnancy, what causes your allergic sneezing may be some external substances that you were not allergic to before, which is rhinitis during pregnancy. You can use simple saline drops for your nose, and if that is not effective, you can use some nose drops to relieve the sneezing and nasal congestion. Sometimes a hot bath or a humidifier in the room can also help relieve the symptoms. 3. Colds and flu: After pregnancy, your immune system drops, and you may be more prone to colds and flu, as well as sneezing, nasal congestion and a runny nose. Usually, for colds, you don’t need to take medication and just drink plenty of hot water and take rest. However, if the symptoms of sneezing, nasal congestion and runny nose are more serious, you can still use some nose drops to control the symptoms properly. Sneezing matters: 1, do not pinch the nose: sneezing do not pinch the nose, to give the mouth and nose to leave a certain amount of space to decompression, to avoid sneezing the huge pressure generated by the Eustachian tube through the role of the tympanic membrane in the ear canal. 2.Don’t sneeze on people: when you want to sneeze, you should immediately turn your face back to others and cover your mouth and nose with a clean handkerchief or tissue. 3.Avoid bending over to sneeze: Many people will habitually do the action of bending over and lowering the head when sneezing, in fact, it is easy to cause lumbar muscle injury and disc herniation due to strong reactive lumbar muscle twisting and uncoordinated contraction. 4, squatting sneezing: squatting sneezing can reduce the pressure changes in the chest and abdominal cavity, reducing the possibility of danger caused by sneezing. When sneezing standing, it is best to put one hand on the waist to support the body, or consciously contract the neck and waist muscles to fight against the impact and protect the spine. A semi-squatting position is also a good position to take immediately in case of emergency. Symptoms caused by sneezing during pregnancy: 1, abdominal pain: under normal circumstances, sneezing may cause mild pain, but the symptoms are mild and short-lived, which is normal. 2, Bleeding: If it causes severe abdominal pain and bleeding, medication is needed with the aim of controlling the pain and bleeding. If it causes more serious symptoms, targeted treatment is needed for the cause of the sneezing.
