&nbsp;&nbsp; A Infecção do Trato Urinário (ITU),
conhecida popularmente como infecção urinária, é um quadro infeccioso que pode
ocorrer em qualquer parte do sistema urinário, como rins, bexiga, uretra e
ureteres. Esse tipo de infecção é mais comum na parte inferior do trato
urinário, do qual fazem parte a bexiga e a uretra.





&nbsp;&nbsp;&nbsp; A infecção urinária ocorre quando uma
bactéria entra no sistema urinário por meio da uretra e começa a se multiplicar
na bexiga.





&nbsp;&nbsp;&nbsp; Alguns
fatores são considerados de risco para contrair infecção urinária, confira: 



Infecções
     urinárias são mais comuns em pessoas cuja uretra é menor, como no caso do
     sistema reprodutor feminino, ou seja, o caminho que a bactéria precisa
     percorrer para chegar até a bexiga é menor.
Ter
     vida sexualmente ativa facilita a infecção urinária, especialmente as
     vaginais.
O
     uso de alguns tipos de contraceptivos, como espermicidas, também pode ser
     considerado um fator de risco.
Após
     a menopausa, as
     infecções urinárias podem acontecer com mais frequência do que antes, uma
     vez que a baixa quantidade de estrogênio causa mudanças no trato urinário
     de modo a deixá-lo mais vulnerável à ação de bactérias.
Apresentar
     algum tipo de bloqueio no trato urinário, como pedra nos rins e aumento da
     próstata, também são fatores de risco.
Ter
     o sistema imunológico suprimido impede que as defesas do corpo atuem
     propriamente, facilitando a entrada de bactérias que causam infecções.
O
     uso de cateter para urinar também aumenta os riscos de infecção.




&nbsp;&nbsp;&nbsp; Nem
sempre uma pessoa com infecção urinária apresenta sintomas, mas quando surgem,
os mais comuns são: 



Ardência
     forte ao urinar
Forte
     necessidade de urinar, mesmo tendo acabado de voltar do banheiro
Urina
     escura
Urina
     acompanhada de sangue
Urina
     com cheiro muito forte
Dor
     pélvica
Dor
     no reto
Aumento
     da frequência de micções.




&nbsp;&nbsp;&nbsp; Procure um especialista ao perceber os
sintomas típicos de infecções urinárias. Descreva os sinais da doença e tire
todas as dúvidas.





&nbsp;&nbsp;&nbsp; O exame de urina é o método mais frequente
usado para realizar o diagnóstico. A urina é analisada a procura de leucócitos
e traços de sangue, sinais de infecção. Fica pronto em torno de duas horas.





&nbsp;&nbsp;&nbsp; O tratamento de infecções urinárias varia
muito de acordo com o tipo de cada infecção e sua gravidade também. Geralmente,
o tratamento é feito à base de antibióticos. Mas o médico também poderá
receitar um analgésico para aliviar a dor e a ardência ao urinar.
