There is no cough medicine that really works.
When a child needs to see a doctor, they often complain of symptoms such as vomiting, diarrhea, coughing, nasal issues, and fever.
The cough medicine really isn't working again.
People often say, "What should I do if I develop asthma or pneumonia with this much coughing?" However, there are treatments available for asthma and pneumonia.
But a regular cough is something you really can't stop.
Since there is no effective cough medicine, doctors may reluctantly prescribe a cough suppressant.
That is a bronchodilator, so it works for children with asthma. However, it has little effect on a typical dry cough.
In the case of children, for example, if a cough persists for 3 to 4 weeks without any other symptoms, it is generally okay..
The longer, the better, I would say.
For adults, if a cough persists for more than two weeks without a known reason, it is advised to see a doctor, as it could be a sign of lung cancer.
It's not a serious cough, but if a mild cough persists, it could be a sign of lung cancer.
By the time lung cancer is visible on an X-ray, it is often too late.
I want to find it at the point of a light cough, so that's how I refer to adults.
However, when it comes to children, we can say that lung cancer is not a concern, so if they have a persistent cough, it could be something like whooping cough.

Whooping Cough
In the case of whooping cough, the first couple of weeks may present as a regular cough, but after two weeks, it worsens significantly.
You will start to vomit everything you eat and develop a cough from even slight stimuli.It is.
It's not a cause for concern if you have a cough during the day but not at night.
Whooping cough and asthma can be particularly challenging at night.That's right.
Whooping cough can cause a state where you can't sleep at night, often described in musical terms as a staccato cough.
In short, once the coughing starts, I can't breathe.
And finally, when the cough ends, there is a loud sound, and that marks the end of it.
This is really tough and can weaken the body.
Whooping cough in adults is often mild, typically presenting as a light cough.
However, since whooping cough that affects adults can sometimes be transmitted to babies, it's actually better for adults to be cautious.
In children, whooping cough has significantly decreased, and it is a distinct and easily recognizable illness.
In the case of asthma
Asthma is a condition where the airways narrow, causing difficulty in breathing. In severe cases, this difficulty can persist from night until dawn.
It usually settles down around 10 AM.
When things get really bad, you may lose your appetite, and if it gets worse, it can become difficult to speak, leading to a reluctance to talk.
For asthma, there are medications that can widen the narrowed airways, and inhaling them can provide significant relief.
There is also a cough that comes from the nose.
It's quite common to cough when you wake up in the morning, go to bed at night, or wake up from a nap.
This is basically mucus building up in the back, causing coughing.That's right.
As adults, we blow our noses and clear our throats ourselves, but babies don't do that.
When standing, accumulated nasal mucus drips down into the throat and enters the stomach, where it is sterilized.
However, when lying down, mucus tends to accumulate in the nose while sleeping.
When you are sleeping, the cough center is suppressed, so you don't cough. However, when you wake up in the morning, you need to clear the accumulated mucus, which is why you start coughing.
There's no need to worry about this. When you go to an ENT specialist, they might tell you to treat your nose endlessly, but I think it's better to avoid that.
Many babies tend to have rhinitis, so during the seasons when they are more prone to runny noses,
It is common to have a cough due to a stuffy nose.It is.
