For example, it controls digestion, respiration, the contractions of the heart and of smooth muscles in blood vessels, and the release, by the endocrine system, of hormones which regulate metabolism and growth. Hormones themselves can influence behaviour by their effects on specific parts of the brain.
Hematuria is also common in older men due to the use of certain medications or prostate enlargement. Blood in urine may occur due to infection, inflammation, or injury to the urinary system. Small amounts of blood are typically associated with kidney damage, while lower urinary tract conditions lead to gross hematuria. Kidney and ureter stones commonly cause hematuria in individuals younger than 40 years of age.
It might be a bladder or kidney stone, bobbling around causing irritation of the lining and therefore blood. Or it may be an early warning sign of a kidney cancer, ureteral cancer or even a bladder cancer. Whatever the cause, blood in the urine is not normal at any time and must be evaluated. Sure, if there is an infection, and thereâs no more blood after the infection is treated, then no further assessment is necessary. But that is because there was an obvious cause of blood, that when treated, resolved.
