Ammonia is a colorless gas that has a pungent smell which can be easily detected. It is composed of nitrogen and hydrogen atoms. The amino acids in the body contain nitrogen. Amino acids are converted into energy and utilized by the body for various functions. In this process the nitrogen atom is stripped off the molecular structure. The nitrogen that remains in excess is sent to the kidneys for processing where urea is created. Urea is eliminated from the body through the urine. If the nitrogen is in excess and the kidneys are unable to take the load and the nitrogen is expelled through the sweat. Since the means of excretion of ammonia is through the urine and sweat, adequate water intake is necessary. As such the sweat is likely to smell of ammonia if the body is not getting the required amount of water. This is possible also if an excess amount of amino acids are being utilized for energy.
It is usually believed that if the sweat smells like ammonia, then it is indicative of a low protein intake. This is a mistaken notion as the body turns to protein for energy only when the content of carbohydrates and fats is insufficient. The ammonia smells comes when the amino acids are processed in the body. Increasing the intake of proteins will only supply more amino acids, thereby increasing the smell of ammonia. As such it is important to provide the body with the fuel that it needs, namely carbohydrates. Eating sufficient content of carbohydrates daily will supply the body with enough fuel for daily energy. The smell of ammonia may also be countered by consuming low glycemic carbohydrates before exercise. Eating a snack of oatmeal or whole wheat bread or even an apple will ensure that your body gets the necessary fuel for daily activities.
The smell of ammonia in the urine could also be indicative of dehydration. Certain medications and vitamins may also cause the urine to take on a distinct odor. Foods such as asparagus also have this effect. In some cases, strong smelling urine could indicate an underlying condition such as an infection, in which case a consultation with the doctor is required. Ammonia odor in the urine can result from an infection by the bacteria called helicobacter, which also causes ulcers in the stomach. Cutting down on intake of foods such as fish, meat, chicken and dairy products will help to reduce the smell of ammonia in the sweat and urine.
