UTIs can have serious consequences, such as spreading to the kidneys or bloodstream. In these cases, seeking medical attention from your GP or calling 111 is crucial. UTIs are more common in certain groups, such as diabetics, who are at higher risk due to their weaker immune systems. Women are also more prone to UTIs, partly because of anatomical differences with men. Contraceptive methods, such as diaphragms, can also increase a woman's chances of developing a UTI. Pregnancy can further increase the risk due to hormonal changes and pressure on the urinary tract. Postmenopausal women and elderly individuals are also at higher risk due to lower estrogen levels and age-related bladder changes.
