Obstetrics is different from other departments, some cases may be delayed if you do not consult a doctor in time, and even cause a bad situation, recently I have seen several cases of delayed mothers-to-be, and some of them have particularly serious consequences. The first hospital of Chongqing Medical University has a lot of people who are worried about the fetal lack of oxygen. 3, after 32 weeks, fetal movement disappears, decreases or suddenly increases (for fear of the baby lacking oxygen, causing 4, pregnancy complications of pain in sensitive areas: full abdominal pain, right lower abdominal pain, localized pain in the waist, headache and eye pain (fear of combined medical and surgical diseases, appendicitis, urinary stones, hypertension, etc.); 5, serious cold symptoms during pregnancy, such as fever, chills, general weakness, etc. (fear of delaying the condition and causing miscarriage and preterm delivery or even stillbirth); 6, sudden onset of diarrhea and vomiting (untreated gastroenteritis There may be induced contractions); 7, labor (I am not a woman, can not text to describe the feelings of labor, but if there is a regular progressive aggravation of contractions should be consulted) 8, sudden onset of periodontitis (there is evidence that periodontitis without treatment may cause miscarriage or preterm delivery); the reality of more than these, but these are very common, we should pay more attention to da, do not delay.
