What is the cause of bad breath

summary

In modern society, stomach diseases are increasing, most of them are caused by (HP) Helicobacter pylori infection. As long as there is gastritis, there will be Helicobacter pylori infection. The principle of C14 breath test is: after entering the stomach through oral C14 urea capsule, if HP (Helicobacter pylori) exists in the stomach, the bacteria will decompose urease to hydrolyze urea, and then urea After being hydrolyzed, carbon dioxide will enter the lungs with the blood and be discharged as gas. Then, whether there is marked C14 in the exhaled gas of the patient will be detected. If there is, it means that there is HP. If not, it means that there is no infection. Here we will explain the reason for this situation.

What is the cause of bad breath

Reason 1: the suitable population of C14 breath test: the first diagnosis of dyspepsia (short history, less than 45 years old, no stomach disease alarm symptoms), the second follow-up, gastroduodenal ulcer, peptic ulcer, obviously abnormal chronic gastritis, gastric MALT lymphoma and other patients requiring eradication of Helicobacter pylori; 3. Prevention of gastric cancer and family history of gastric cancer; 4. Refusal of gastroscopy 5. Other Helicobacter pylori related diseases: rosacea, measles, liver disease, halitosis, cholelithiasis, liver cirrhosis, diabetes, iron deficiency anemia, child dysplasia, migraine, coronary heart disease. The figure below shows the growth rate of Helicobacter pylori positive patients.

Reason 2: contraindications before C14 breath test: anti inflammatory drugs and most cold drugs can not be taken, and drugs containing proton and ionic agents can not be taken, which will affect the test results, and may cause false negative (for example, the result < 100 is normal, your test result is 90, which is negative, and it is possible that your HP content is higher than 100, because these drugs inhibit the growth of HP Activity: part of HP is not in the active stage, the drugs taken cannot be decomposed by HP, and the gastrointestinal tract will not be absorbed, so the HP content determined may be less, resulting in false negative). It is necessary to stop the drug for one to two weeks, and then conduct 13C or 14C breath test to be accurate.

Reason 3: whether C14 breath test is harmful: because of its marker urea C14 is a radioactive marker. Therefore, many patients are worried about radiation problems. But experts said that up to now, there has been no gene mutation, alienation and other phenomena due to C14, so this test is safe. The half-life of C14 is 5000 years, and there is indeed radioactivity, but the measurement during the experiment is medically allowed, and it is almost harmless to the surrounding people. Therefore, please rest assured to check.

matters needing attention

Fasting is required before the examination, and the correct drug treatment is selected according to the results after the examination. In order not to let us cast a shadow in the social circle, we should find out the cause and then treat it.
