i am a biochemist graduate.....looking at amino acid metabolism as the key to solving dis problem. Most people suffer from hypermethioninemia...its foul smelling. Its an elevated level of methionine build up in d blood which cannot be broken down to cysteine. The second possibility is dimethylsulfonuria. If its foul smelling, just knw it has somethin to do with ur amino acid metabolism which could be hereditary or inherent. UTI is also a possibility. A few suggestions i'd make is avoid foods like eggs, milk, food containin phenylalanine, leucine, valine, methionine, also red meat, beverages, etc....PLEASE DRINK LOTS OF WATER...PLEASE PLEASE!!!
Usually urine smells bad when you are dehydrated or have a bladder infection. If you are having any pain associated with urination, see a doctor right away. Otherwise, you are more then likely just dehydrated. Start drinking more water and you should notice a difference.
Your first morning urination normally smells bad because it is most concentrated, having been stored all night long. Dehydration can also cause your urine to become concentrated, and therefore foul-smelling. Some medications, such as penicillin, may give urine a strong smell, and bacterial infection could have the same effect.
If your urine smells bad, this could mean that you have a urinary tract infection, bladder infection, or kidney infection. You need to see your doctor for confirmation, and an antibiotic. Go here for more information: www.webmd.com.
