Women’s physiological structure and hormone levels are changed during pregnancy, which can easily lead to urinary tract infections. The following measures should be taken to improve or eliminate the symptoms: 1. drink more water, keep the amount of water at 1500-2000ml; at the same time, nutrition should be sufficient, eat more fiber-rich food; 2. change underwear regularly to avoid bacterial growth; 3. avoid uncontrolled sex to prevent vaginal secretions or anal excretions from contaminating the urethra; 4. sleep in a side-lying position, preferably on the left side. Especially in the middle and late pregnancy, we should pay attention to this. 5. If the symptoms of urinary tract infection are obvious, or accompanied by fever and other symptoms, you should consult a doctor in time and take the full amount of medication under the guidance of the doctor to actively treat the problem, avoiding unauthorized use of drugs, which may affect the fetus.
