When you feel like you still have to pee even after peeing it's a common sign of having a urinary tract infection.
However other conditions can also cause you to fee like you still have to pee after peeing which includes interstitial cystitis, pregnancy, weak pelvic floor muscles, alcohol consumption, caffeine consumption or an overactive bladder.
Urinary tract infections are a common cause of having to urinate frequently and having an incomplete bladder emptying that is often accompanied with a burning feeling during peeing or urination.
Having an overactive bladder is a condition in which your bladder muscle contracts too often and leads to a strong urge to pee or urinate even when your bladder is not full.
Bladder irritants such as consuming alcohol, spicy foods, caffeine, or acidic drinks can irritate your bladder and lead to frequent urination.
Weakened pelvic floor muscles can lead to urinary incontinence and a feeling of an incomplete bladder.
The pelvic floor muscles support the bladder and your urethra.
Hormonal changes during pregnancy can also increase the frequency of needing to urinate.
Interstitial cystitis is a chronic bladder condition that causes pelvic pain and frequent urination and often with a feeling of urgency.
Prostate issues in men can also lead to feeling like you still have to pee after you pee and an enlarged prostate can obstruct urine flow and lead to a feeling of incomplete bladder emptying.
If you experience any frequent urination and it doesn't get better or you continue to still feel like you have to pee after peeing you should see a doctor to find out the exact cause although most times it's nothing serious.
