6 Diseases Can be Diagnosed from the Smell

If not bathe all day, clear body odor wafted others easier. But it was not just cleanliness that can be detected by smell, but also disease. In fact, there are several physical and mental ailments that can be identified by the odor sufferers.

Changes in the metabolism of the body to release some chemicals that can be detected by smell. Some dogs have been specially trained to detect cancer in humans through body odor. The scientists have also developed special tools to detect disease through body odor.

As reported by Wired, there are some diseases that can be identified from the smell, that is:



1. Lung Cancer

In patients with lung cancer, his breath smells more like ammonia or fishy smell of fish. The cause is a chemical called methyl hydrazine. To detect it, you can use a network of gold nanoparticles that are given organic layer chemiresistive.

Volatile chemicals produced from breath will make the particle sensor expands and modify electrical resistance and allow scientists to identify signs of cancer through patient breath.





2. Preeclampsia

This disease primarily affects pregnant women. The sign is an increase in blood pressure followed by increased levels of protein in the urine. It is also accompanied by swelling in the feet and hands.

In this disease, his breath smelled of lighter fluid. The reason is the 6-methyltridecane chemicals, 2-methylpentane, 5-methyltetradecane, 2-methylnonane. To detect the presence of chemical compounds, to do gas chromatography or mass spectrometry to look at markers of oxidation in the body of the pregnant woman.




3. Diabetes

Not just diabetes that can emit a certain smell, but kompilkasinya called diabetic ketoacidosis. These complications can compromise the safety of the soul because the body lacks insulin. As a result, the body will burn fatty acids and ketones produce acids that cause complications.

In patients with complications of diabetes, his breath smelled like rotten apples or cleaning polish. Its source is acidic ketone or acetone produced by the liver to produce energy because blood glucose can not be absorbed by the body.






4. Schizophrenia

Schizophrenia does not immediately bring up a particular scent because this disease is basically a mental disorder. But it turns out, this disorder is also associated with metabolic changes that cause the patient has a slightly different flavor.

Rats that had been trained were able to distinguish the sweat of schizophrenic patients and normal people. People with schizophrenia have a component called acid trans-3-methyl-2 hexenoic. The aroma of this material is described as sweet, like ripe fruit aromas.




5. Urinary Tract Infection

One sign of a urinary tract infection is a strong smell of ammonia or even a little sweet. There is also a call like odor smelled like cheese. This odor can be smelled of urine, but also can be smelled through the pores of the body.

The cause is isovaleric acid produced by the bacteria E. coli, Staphylococcus, and parasites proteus. To detect it, can use a tool called an electronic nose. This tool is equipped with 14 types of conductive polymers that can distinguish the smell of some types of bacteria.




6. Melanoma

Patients with skin cancer or melanoma often resembles a gasoline smell on her skin. The cause is phthalate, butanal, dimethylsulfone and indole. The smell is more pronounced because of cancer found in the outer portion of the body, the skin.

To detect the presence or absence of skin cancer, can be used gas sensor array. This device can analyze volatile chemicals from the tube tissue specimens to determine if the sample is positive for cancer or not.
