Meth and the Brain. Meth releases a surge of dopamine, causing an intense rush of pleasure or prolonged sense of euphoria. Over time, meth destroys dopamine receptors, making it impossible to feel pleasure.
CAUSES OF HIGH AMMONIA. Ammonia is a normal by-product of processing nitrogen in the body, and is excreted as waste in the urine, in healthy people. However, elevated blood ammonia levels can occur when the kidneys or liver are not working properly, allowing this waste to remain in the bloodstream, which can be poisonous to your cells.
The Test Sample. Ammonia is a waste product formed primarily by bacteria in the intestines during the digestion of protein. If not processed and cleared from the body appropriately, excess ammonia can accumulate in the blood. This test measures the amount of ammonia in the blood. Ammonia is normally transported in the blood to the liver, where it is converted into two substances called urea and glutamine. The urea is then carried to the kidneys, where it is eliminated in the urine.
