There are different factors on how sexual intercourse can cause UTI. First, thrusting while having sex can introduce more bacteria up the urethra and into the bladder.
Second, sexually transmitted diseases like chlamydia and gonorrhea can trigger UTI. You can get STDs from having multiple sexual partners and by not practicing good after-sex hygiene.
Men older than 50 are more vulnerable to prostate problems as well as UTI. Prostate problems like prostate gland enlargement can block the flow of urine coming from the bladder. When this happens, bacteria gets stuck in the bladder and continues to multiply, which results in UTI.
People with diabetes have weak immune systems that leave them unprotected from infections and other diseases. Diabetes can cause UTI due to high glucose levels and nerve problems.
Diabetics who suffer from nerve damage can find it difficult to urinate normally. This results in the retention of large amounts of urine in their bladder, which can set off UTI.
Stool build-up in the rectum and colon can press on the bladder and urinary tract, making it difficult for someone to empty their bladder completely. When urine is left in the bladder for too long, bacteria will grow and cause infection.
Menopause can cause UTI since hormonal changes can alter the balance of bacteria in a woman’s vagina. In addition, there are changes in their reproductive organs like the urethra, which makes it more susceptible to UTI.
Old age can cause UTI since older people are more vulnerable to infections due to poor immunity. They can easily develop UTI as they may have difficulty reaching the restroom and emptying their bladder.
Those people who are in the hospital, bedridden, or are incapable of visiting the restroom by themselves use urinary catheters to collect urine. However, a urinary catheter is also an easy access point for bacteria to travel up the urinary tract.
A urinary catheter can also gather bacteria before it is inserted, or it can accumulate bacteria during its time in the bladder.
Invasive surgeries or procedures within the urinary system can make one more prone to UTI. Surgeries that involve the urinary system include kidney removal (nephrectomy), bladder surgery, and surgery of the urethra.
