Frequent Urination During Pregnancy When does it start

In most cases, frequent urination mainly is experienced in the first and the third trimester. Doctors claim that it may change due to a number of factors including hormone levels and increased body fluids.

You will experience frequent urination as early as the first 2-3 weeks of the pregnancy. Mostly, it is noticed during the 10-13th week when your uterus starts exerting pressure on the bladder. This is according to G. Thomas Ruiz, MD, who is an ob-gyn in Orange Coast Memorial Medical Center located Fountain Valley, California.

The urge to urinate regularly will reduce during the 2nd trimester. At this stage, the uterus goes past the pelvis, thereby relieving pressure on the bladder. The urge will, however, come back around the 30th week. Here, the baby’s head presses against the bladder.

Causes of Frequent Urination During Pregnancy

In case you experience frequent urination during pregnancy, below are some factors to blame.

Increased Blood in the body

The urge to pee a lot can be caused by an increased amount of blood in the body. In order to process the increased blood flow, your kidneys must produce additional fluids.

In fact, during pregnancy, body fluids increase twice as compared to normal levels.

According to research, the blood flow towards the kidney increases by approximately 35-60%. This results in about 25% more urine production especially immediately after conception.

For instance, causes increased blood flow towards the kidneys and the pelvic region. Since your body is getting rid of waste products quickly, it will expel it through the urinary tract.

Pressure On The Bladder

Pressure on the bladder is another common cause of increased urination in pregnant mothers. This is experienced during the last 3 months to delivery. As the baby to grow bigger, the baby tends to move down further into the pelvis. Your uterus will then begin to expand as the baby moves towards the bladder. As the baby grows, it will exert pressure on your bladder. This limits the duration of your bladder can last before it is emptied.

Urinary Tract Infection

It’s rare but possible that frequent urination can be as a result of bladder infection and if left untreated for long, it can cause serious complications. Urinary Tract Infection can also present other symptoms such as a burning sensation when urinating, blood spots in the urine, and pain at the end of urination.
