What causes frequent urination during pregnancy?

Patient's question:

At 28 weeks pregnant, frequent urination, always leaking urine, underwear always wet, what's going on

Doctor's answer:

At 28 weeks of pregnancy, as the months progress, the overdistension of the uterus decreases, reducing pressure on surrounding structures, including the bladder. This can lead to frequent urination. If the bladder sphincter is relatively relaxed, there may be a recurrence of incontinence. Therefore, it is important not to hold urine. This issue usually resolves after childbirth.
In addition, during the treatment of male urological conditions, besides medication, the patient's dietary habits and psychological state are also particularly important. It is essential for patients to maintain a positive mood and eat a balanced diet to avoid unnecessary interference with the recovery of male urological conditions.
