Hi

1
00:00:00.825 --> 00:00:04.025
I'm Hye-sun Kang from the department of pulmonology at the Catholic University of Korea Bucheon St. Mary's Hospital

2
00:00:04.275 --> 00:00:08.024
What is asthma?

3
00:00:08.024 --> 00:00:11.224
Asthma is characterized by chronic respiratory tract inflammation

4
00:00:11.474 --> 00:00:15.974
This causes limitation in airflow which results in

5
00:00:15.974 --> 00:00:20.924
shortness of breath, light breath, cough, and chest pain in patients

6
00:00:21.224 --> 00:00:24.823
We call it asthma when there are these respiratory symptoms

7
00:00:25.573 --> 00:00:28.273
What causes asthma?

8
00:00:28.823 --> 00:00:33.373
First of all, if the patient has eczema, a genetic factor that causes limitation in airflow,

9
00:00:33.673 --> 00:00:37.223
obesity, or is a female, there is a high risk of getting asthma 

10
00:00:37.723 --> 00:00:40.572
Environmental factors include house dust mites, 

11
00:00:40.572 --> 00:00:45.322
animals like dogs and cats, allergic antigens such as mold and pollen,

12
00:00:45.322 --> 00:00:46.722
infection caused by viruses,

13
00:00:46.972 --> 00:00:50.372
air pollution and smoking can cause Asthma

14
00:00:51.222 --> 00:00:55.172
Main symptoms of Asthma

15
00:00:55.172 --> 00:01:00.521
Typical symptoms of Asthma are light breath, chest pain, difficulty in breathing, and cough

16
00:01:00.871 --> 00:01:04.721
Other characteristics of Asthma besides symptoms?

17
00:01:04.921 --> 00:01:07.571
The characteristic of asthma is that the symptoms change.

18
00:01:07.571 --> 00:01:11.121
Especially the symptoms get worse in the morning or night,

19
00:01:11.620 --> 00:01:14.720
change in terms of time and degree

20
00:01:15.170 --> 00:01:20.520
or get worse after exercise or exposure to allergic antigens and cold air

21
00:01:21.070 --> 00:01:23.820
There is a high chance of Asthma especially when

22
00:01:23.820 --> 00:01:27.170
symptoms worsen after taking aspirin or beta-blockers

23
00:01:27.919 --> 00:01:32.919
In what season does Asthma usually occur?

24
00:01:32.919 --> 00:01:36.069
It depends on the allergy that patients have

25
00:01:36.419 --> 00:01:40.119
Patients who are allergic to pollen,

26
00:01:40.119 --> 00:01:42.969
symptoms may occur in spring

27
00:01:43.268 --> 00:01:47.218
In the case of patients with persistent Asthma, the symptoms can worsen

28
00:01:47.218 --> 00:01:50.118
when exposed to cold air or when they catch cold

29
00:01:50.418 --> 00:01:55.018
symptoms can worsen during the change of seasons into autumn or winter.

30
00:01:55.568 --> 00:01:58.518
Treatments for Asthma

31
00:01:58.768 --> 00:02:03.467
As I said, Asthma is characterized by chronic respiratory tract inflammation 

32
00:02:03.767 --> 00:02:08.067
it is most important to use a steroid inhaler to treat inflammation in the respiratory tract

33
00:02:08.917 --> 00:02:12.317
If symptoms are not controlled by a steroid inhaler

34
00:02:12.667 --> 00:02:16.316
which we call acute exacerbation

35
00:02:16.516 --> 00:02:20.266
It is helpful to use systemic steroids in case of acute exacerbation

36
00:02:20.766 --> 00:02:30.416
How to prevent Asthma and which food is good for Asthma?

37
00:02:30.416 --> 00:02:36.465
The most important thing is to not get exposed to allergic antigens that can trigger Asthma

38
00:02:36.765 --> 00:02:40.465
Therefore, for patients with allergies, it is  most important to

39
00:02:40.465 --> 00:02:44.665
not get exposed to allergic antigens but after getting diagnosed with Asthma

40
00:02:45.115 --> 00:02:49.064
and experiences Asthma symptoms frequently,

41
00:02:49.064 --> 00:02:51.914
it is important to consistently use a steroid inhaler to control the symptoms

42
00:02:52.414 --> 00:02:57.964
Even when utilizing a steroid inhaler, you should be aware of not getting exposed to allergic antigens

43
00:02:58.214 --> 00:03:00.564
Even if you use a steroid inhaler

44
00:03:00.964 --> 00:03:06.063
and are careful not to be exposed to allergens, there are cases where Asthma symptoms are not controlled

45
00:03:06.313 --> 00:03:11.113
In that case, it is known that using biological agents is helpful these days

46
00:03:11.463 --> 00:03:13.663
Does asthma also have complications?

47
00:03:14.513 --> 00:03:17.313
Asthma is a condition that by simply using a steroid inhaler

48
00:03:17.313 --> 00:03:22.462
relieve symptoms and preserve lung function well.

49
00:03:22.462 --> 00:03:29.462
But if asthma is not controlled well and acute exacerbations repeat, it may result in decreased lung function

50
00:03:29.462 --> 00:03:32.562
In this case, the patient can have chronic difficulty in breathing

51
00:03:32.862 --> 00:03:38.261
Use of inhalation steroid can raise the risk of pneumonia

52
00:03:38.261 --> 00:03:41.561
So in the case of patients with chronic respiratory disease like asthma patients

53
00:03:41.811 --> 00:03:44.411
Getting pneumonia vaccinated would be helpful

54
00:03:44.861 --> 00:03:49.211
Is asthma hereditary?

55
00:03:49.611 --> 00:03:55.460
When you have allergic diseases like eczema

56
00:03:55.460 --> 00:03:57.560
The prevalence of asthma increases

57
00:03:58.160 --> 00:04:01.760
If you have a family member who has a genetic factor in eczema or asthma

58
00:04:01.760 --> 00:04:05.210
The risk of asthma may increase

59
00:04:05.809 --> 00:04:08.209
That is all for asthma today

60
00:04:08.209 --> 00:04:08.959
Thank you
