What Causes Uti Infections
Infections are invasions of some other organism (fungus, bacteria, parasite) or viruses into places where they do not belong. For instance, we have normal gut bacteria that live within us without causing problems; however, when those penetrate the bowel wall and enter the bloodstream, ...Read more
Candida (overgrowth): Candida is the usual cause of yeast infections in a person. Candida is always in or on our bodies, in small amounts that are invisible. Candida lives with us, normally. It causes symptoms if it invades into parts of our bodies where candida is not supposed to go, or it causes symptoms if it is indeed staying where it should but is overgrowing in large amounts (such as with oral or vaginal thrush). ...Read more
Bacteria: Utis are caused by bacterial migration into the urethra/bladder. Hygeine (not wiping front to back, etc) may be an issue. Urinating before and after intercourse helps to decrease risk of uti. Cranberry juice and increasing water intake may help prevent bacteria from sticking to the bladder wall. Recurrence may indicate anatomical or medical (diabetes, hiv, etc) problems and warrant a work up. ...Read moreSee 1 more doctor answer
Fungus: Yeasts are microscopic organisms that are a type of fungus. Abnormal overgrowth of these fungi happen in a "yeast infection". This can be triggered by changes in ph (acidity) of the environment / anatomic location or by other factors such as taking antibiotics (which cause altered flora). Decreased immune system function may also be related to yeast infections. Hope that this helps. ...Read more
More than natural: Having more yeast than there naturally should be in a particular part of the body... is what causes a yeast infection. Yeast and fungi are part of our lives on Earth. They are always with us, but when they end up in places or in numbers that are not natural, we call it an infection. Sometimes we call it an overgrowth, if the location is normal but the yeast numbers are too high. ...Read more
Many: Bacteria multiplying in bladder. Not urinating after sex, allowing bacteria which reached bladder ; multiply. Using bubble-bath and tub baths rather than taking a shower, severe constipation, sub-optimal toilet hygiene- not wiping front to back or holding thighs together with urinating + trapping urine behind labia, witholding urination, thongs and non-cotton underwear. ...Read more
Varies.: For females, it ismore common compared to male, due to the proximity of the bladder opening( urethra)to the anal opening.So wiping backwards is one way to reduce the risk.An abnormality of the urinary tract in both sexes such as posterior urethral valve in men, or polycystic kidney disease in both sexes will be another reason for frequent infections. ...Read more
Bacteria: I think you are referring to bladder infection or "cystitis".Bacteria can go up the urethra,which is short & straight in females,into the bladder. Always empty your bladder by urinating after sex.Always wipe from the front backward after urinating and not the other way so bacteria from the rectal area are not brought forward.Hope this answers. ...Read more
Several factors: Several factors can cause chronic yeast infections- 1. Local balance of normal flora is disrupted, typically from the recent user of antibiotics; 2. Impaired immunity- this may be due to steroid use or having other illnesses such as hiv; 3. Misdiagnosis of symptoms in the absence of yeast from testing- adverse drug effects can be mistaken as a yeast infection. Consult your gyn or id specialist. ...Read more
Micro organisms!: There are several types of urinary tract infections (uti's). Urethritis is inflammation of the urethra; cystitis the bladder; pyelonephritis the kidney. Urethritis can be due to chemical irritation (soaps, sprays, medications); std's like gonorrhea, chlamydia, or herpes; or bacteria migrating from our skin and rectum. As the site of infection goes up the tract, bacteria are the primary players. ...Read more
Intercourse: Many urinary tract infections in women occur after sex because the vaginal and rectal areas are so close to the urethra where women urinate from. Sex allows bacteria from these close areas to be spread toward the urethra. Urinating immediately after sex can decrease the number of infections. If they are still frequent, sometimes doctors will prescribe a medicine to take each time after sex. ...Read more
Bacterial invasion: This is a very broad question because there are hundreds of bacteria that cause human infection and there are many causes. In general terms when a pathogenic bacteria can attach to or invade through a surface of the body or intestinal tract or lungs in a susceptable person they can initiate an infection. ...Read more
A urinary tract infection, also known as an UTI, may involve the kidney, ureter, bladder, or urethra. A common cause is an intestinal bacteria, E. coli. Common symptoms include a frequent urge to urinate, and pain or burning when urinating. Antibiotics are typically ...Read more
