As pregnancy progresses, physical changes can place pressure on the bladder. Hormonal changes and changes in fluid balance can also affect urination.
Some women may continue to experience bladder-related symptoms after childbirth, particularly if the pelvic floor muscles have become weaker.
5. Diabetes
Frequent urination can sometimes be associated with diabetes.
When blood glucose levels remain high, the kidneys may remove more glucose through the urine. This can cause the body to produce more urine.
Nighttime urination accompanied by excessive thirst, unexplained weight loss, unusual fatigue, or other symptoms should be discussed with a healthcare professional.
6. Enlarged Prostate
In men, an enlarged prostate can interfere with the normal flow of urine and cause urinary symptoms.
These may include:
- Frequent urination
- Difficulty starting urination
- A weak urine stream
- A feeling that the bladder has not completely emptied
- Getting up several times during the night
Persistent urinary symptoms should be evaluated by a doctor.
7. Heart or Kidney Problems
Certain heart and kidney conditions can affect the body’s fluid balance and contribute to nighttime urination.
For example, people with some forms of heart failure may retain fluid in their legs during the day. When they lie down at night, some of that fluid can return to the bloodstream and eventually be processed by the kidneys.
