I've had a recent string of infections, 4 uti's in a 6 month period. strep throat in addition to two, week long, stomach bugs. is this all related?

See below: The uti's might be related. Recurrent uti's in young women can occur after intercourse and if frequent require a dose of antibiotic after each contact. Other causes of recurrent uti's include incomplete emptying of the bladder, reflux of urine up the ureters with voiding and urinary stones. Get checked out by a urologist or infectious disease specialist.

Multiple infections: There is a possibility that all the infecions may be related.You should see your doctor and have a panel of blood tests to make sure your immune system is intact.These tests should include gamma globulins, complement levels as well as a complete CBC and urinanalysis. Above all, institute better hygiene at home.

Difficult issue: I can't link the two separate systems together as one problem. The uti's in a young woman are more related to the design of your bladder and urethra and a tendency for germs to enter from below.Sexual activity of any sort can add to the risk.The strep throat and stomach bugs are different types of germs and involve different parts of the immune system.Bad luck rather than a bad system is likely.

That's a lot: If you haven't had utis since you were younger, then it could be related to sex. You should void after intercourse to prevent them. If that doesn't work, sometimes you need an antibiotic after sex. The strep and other bugs could be from sharing things with someone else who has different flora (germs) than you do and you are not immune to them all. If things don't change you might need testing.
