If you experience a strong smell of urine after pregnancy, priority should be given to whether it is caused by physiological factors. Firstly, after pregnancy, the level of estrogen and progesterone in the body will increase, leading to endocrine disorders and the possibility of producing a strong smell of urine. Secondly, the metabolic level of the pregnant woman’s body increases, which may lead to an increase in nitrogenous metabolites in the urine and an increase in the smell of urine. If the urine smells bad due to the above two reasons, it can usually recover on its own without intervention. In addition, fire during pregnancy may also cause urine to smell worse, which can usually be relieved by drinking more water and eating more fresh fruits and vegetables. If it is not caused by physiological factors, then pregnant women need to consider whether they are suffering from gynecological diseases. An increase in vaginal discharge may irritate the urethra and cause a urinary tract infection. Pregnant women can be tested for the disease through routine urination and white belt routine and be treated under the guidance of a doctor. At the same time, pregnant women who have urinary tract infections should drink more water so as to help the discharge of inflammation, pay attention to their diet and strengthen their immune system.
