According to the Information Times, recently, Montmorillonite Powder, a commonly used household drug for treating diarrhea, unexpectedly became a hot search topic. The reason is actually that some netizens said that the XBB strain that has been killing everyone abroad is about to enter China, and this strain mainly attacks the heart, brain and gastrointestinal tract. Is what netizens say true?
Chen Yong, deputy chief physician of the gastric surgery department of the Sixth Affiliated Hospital of Sun Yat-sen University, and Lian Lei, chief physician of the gastric surgery department, who are supporting the hospital's new crown treatment work, verified the authenticity of the above information.
There is no evidence that XBB 1.5 causes severe diarrhea
It is reported that the two B's in the XBB strain mean the recombinant strains of BA.2.10.1 and BA.2.75. It can be understood that these two virus strains infected someone at the same time and then completed the recombination in the person's body. Therefore, it essentially belongs to the Omicron series of strains.
According to the latest data released by the US CDC, the strain XBB1.5 popular in the United States has just emerged in late November. By December 31, 2022, cases infected with this strain have accounted for 40.5% of all strains, almost half of the country.
U.S. CDC official and Boston University Dr. Barbara Mahon once pointed out that there is not much evidence that XBB 1.5 is more dangerous than past strains; there is also no evidence that XBB 1.5 will cause more severe diarrhea, but gastrointestinal symptoms such as diarrhea, nausea, and vomiting are already among the symptoms of the new coronavirus.
Chen Yong, deputy chief physician of the Gastric Surgery Department of the Sixth Affiliated Hospital of Sun Yat-sen University, explained vividly, "In other words, if you are infected with the BQ1 strain, it is like being hit with a left hook, so your body has a memory (antibody). Next time you encounter a right hook (similar strains such as BQ1.1), you will most likely be able to prevent it, but if you encounter someone who suddenly gives you a shovel (XBB 1.5), you may have been tricked again. "
Doctor: It is not necessary to stock up on anti-diarrheal drugs.
The reporter learned that some time ago, anti-diarrheal drugs such as montestone powder and norfloxacin were available online. However, starting yesterday, many citizens began to stockpile montmorillonite powder, so that the drug became a hot seller on the Internet.
In this regard, Chen Yong said that montmorillonite powder is a powdered drug. After being mixed with water and taken orally, it can cover the mucosa of the digestive tract and has a fixing and inhibitory effect on viruses , bacteria and the toxins they produce in the digestive tract. It is indeed a good choice for gastroenteritis and diarrhea caused by viruses, and it can be used safely by children and pregnant women. However, it must be noted that if the frequency of bowel movements simply increases, it is not necessary to use it. If used casually, it may cause constipation.
If the diarrhea is too severe and you have symptoms such as general weakness and collapse, you may have electrolyte imbalance . Simply taking montmorillonite powder will not be effective, so you must seek medical treatment in time.
Norfloxacin is an antibacterial drug targeting bacterial infections, especially a commonly used drug for the treatment of enteritis and dysentery. It has no direct killing effect on viruses.
Chen Yong reminded, "Don't be overly afraid of the XBB strain. If symptoms such as severe diarrhea occur, seek medical treatment in time and use medicine scientifically and rationally."
As for whether it is necessary to supplement electrolyte drinks when diarrhea occurs, Chen Yong pointed out that during diarrhea, the body will lose a large amount of electrolytes, such as potassium ions, sodium ions, etc. Oral electrolyte drinks are indeed helpful to replenish lost electrolytes and slow down the condition. However, not all electrolyte drinks can be used to treat diarrhea.
If excessive amounts of glucose and additives are added to electrolyte drinks, the osmotic pressure of the liquid will be too high. Drinking hypertonic drinks in the case of diarrhea may even aggravate the leakage of the intestinal mucosa, thereby aggravating the condition, so drink with caution.
Medication Instructions
According to the "Guidelines for Home Medication for Key Populations After Infection with COVID-19" issued by Guangdong Provincial Health Commission .
If children develop diarrhea after being infected with COVID-19, they can choose medications such as Montmorillonite Powder, Racecadotril Granules, Oral Rehydration Salt III, and Bifidobacterium Triple Live Bacteria Capsules. During diarrhea, pay attention to replenishing water and observing urine output. If vomiting is obvious and urine output is significantly reduced, intravenous rehydration treatment is required.
If pregnant women develop diarrhea after being infected with COVID-19, montmorillonite powder can be used. Note that it should be taken on an empty stomach and avoid taking it at the same time with other drugs.
According to the instructions for norfloxacin, the safety of this drug in infants and adolescents under the age of 18 has not yet been established. However, this drug can cause joint disease when used in several species of young animals. This medicine should not be used in children and adolescents under 18 years of age.
