Frequent urination and pain may indicate infection, which is related to the low urine output.

A young male patient went to the hospital for treatment and told the doctor that he felt stinging pain in the urethra when urinating, and he urinated frequently, and felt bloating in the lower abdomen and sore waist. His body temperature was measured and he had a low fever. Blood and urine routine tests confirmed that he had a urinary tract infection. After a color Doppler ultrasound of the urinary system, it was found that the kidneys were also infected and he had pyelonephritis.

The young man looked sad and said that he didn't even have a girlfriend and didn't go out to "do bad things", so how could he have a urinary tract infection? The doctor asked him if he drank a lot of water. The young man nodded and said that he always stayed at home to play games. In order to avoid "letting his teammates down" when he went to the toilet, he often held his urine when the game was intense, so he drank very little water.

1. People with less urine output are more prone to urinary tract infection. The doctor told the young man that urinary tract infection is relatively rare in young men, and more common in women. Because of the differences in the physiological structure of men and women, the male urethra is long and curved, while the female urethra is short and straight. But regardless of gender, the common cause of urinary tract infection is not drinking enough water and urinating too little.

Because the human urethra is always in a warm and humid environment, it is easy for bacteria to grow. However, normal human urine is sterile, and urination is a "cleaning" for the urinary tract. When the urine volume is sufficient, it is difficult for bacteria in the urethra to invade the urethra. If they occasionally invade, they will be washed away by urine and will not reach the concentration for reproduction, so urinary tract infection will not easily occur.

Second, never hold your urine. The human immune system has a certain ability to eliminate pathogens. Even if the urinary tract is slightly infected, it is possible to heal itself as long as a large amount of urine is flushed to reduce the concentration of pathogens in the urethra. But the young man did one thing wrong, which led to the further development of his illness, that is, habitually holding his urine.

When a urinary tract infection occurs, if the urine volume is insufficient, bacteria may enter the bladder through the urethra, causing bladder infection, and in men, prostate infection. If you hold back your urine at this time, the pressure in the bladder will increase, which may cause bacteria to retrograde from the ureter into the kidneys, causing a more serious kidney infection.

3. What to do after a urinary tract infection When a urinary tract infection occurs, the first priority is to ensure adequate urine output. Normal people usually need to drink 1500~1800ml of water every day, and people with urinary tract infections need to drink 2500~3000ml of water to ensure adequate urine output to promote the discharge of bacteria and pus in the urethra. People with mild infections can clear the infection by drinking more water, urinating more, and the role of their own immune system.

However, if the infection is severe and has invaded the prostate, bladder, or even the kidneys, antibiotics are needed for treatment. It should be noted that antibiotics must be used under the guidance of a doctor and must not be used without authorization. For example, quinolone antibiotics are effective for urinary tract infections, but they cannot be used by adolescents under 18 years old, otherwise cartilage damage will occur, affecting growth and development. Photosensitivity dermatitis may occur after taking the medicine, and direct sunlight should be avoided during medication.

If cephalosporin antibiotics are used and there is a possibility of allergy, they need to be used under medical supervision or a skin test should be done before use. During the use of cephalosporin drugs, alcoholic beverages should be prohibited to prevent side effects such as "disulfiram-like reactions". For infections caused by pathogens such as mycoplasma and chlamydia, macrolide antibiotics are needed for treatment.

That is to say, when a urinary tract infection occurs, it is necessary to determine what kind of pathogen is causing the infection in order to choose the appropriate antibiotics, and also to avoid the risks of medication. All of these require medical intervention. So when you suspect you have a urinary tract infection, you should see a doctor first, and don't take medication on your own.

To sum up, the best way to deal with diseases is to prevent them from happening. Drinking more water and maintaining urine volume are the best ways to prevent urinary tract infections. If you have symptoms of urinary tract infection, you need to see a doctor for diagnosis and treatment, and take medication under the doctor's guidance. If you have doubts about medication or find problems during medication, consult a doctor or pharmacist in time. I am pharmacist Huazi, welcome to follow me and share more health knowledge.
