Dear VXS,
Ordinarily, yellow, dark or red urine would evoke thoughts of about half a dozen things a)Fever, b) Dehydration; c)Drugs d) Jaundice? e)Excess Sweating? f)Bleeding in the urinary tract? Which drugs are you on that can colour your urine yellow?That is a most important but often forgotten cause. Then when you have some fever, no matter how small, the higher temperature means that you lose more water than if you were afebrile(had no fever). More than normal amounts of water escape from your body (through sweating) via the extra heat you are generating. Moreover, the excess heat also makes your metabolic processes to be more active, using up more body water. This same lack of enough water is a cause of yellow urine. Simply do a test called Urinalysis and then drink more water. Or review your use of the drugs you're using; okay?
