I am allergic to dust. Fucking dust. Its the worst one because its everywhere, all the time and there is almost no way to avoid it.

This video focuses more on food allergies.
It would be great to have a video about allergies specific to indoor environment.
Thank you.

When a cat person is allergic to cats... feels bad

[Confuzledish]

It's difficult to avoid some food allergies though. I'm allergic to fruits and vegetables.

Allergic to: Beef, Dairy, Tree nuts, Peanuts, and I finally outgrew eggs.

Michael saying "twenty-o-seven" made me physically uncomfortable.

I had no allergies as a child, mine developed in my early twenties. I think it started with just birch, but now includes grass, dust, dogs and cats - but I'm also sensitive to anything that has a strong smell, especially perfumes (although that's apparently not an allergy).

I'm allergic to grass pollen. Which is everywhere. Fuck that, I can't escape it.

I do the immunotherapy. Time consuming early on, but definitely worth it. I'm not sure what constitutes an allergy "too severe" as I have a horrific allergy to cats and that is one of the allergens my shots target. Previously, I could just walk into a room that has at some point in the last few weeks had a cat in it and immediately start having issues with my sinuses, my eyes, skin breakouts, and asthma. After nearly two years of this treatment, I now tolerate cats with little to no allergic symptoms at all.

The shots are not something you have to do 1x-2x weekly indefinitely. You start out with twice a week, then increase the dosage and decrease the frequency. Over time, you start getting larger concentrations of allergen spread over intervals of once a week, once every two weeks, once every three weeks, and then a maintenance dose of once a month. Everyone has different degrees of tolerance (or number of allergens they are getting treated) so how long it takes to get to a maintenance dose can vary. I was able to do the accelerated process (two shots at a time) and got to the maintenance level in 6 months. Those who go for one shot at a time take about a year on average, but I have heard of it taking as long as a couple of years- all depends on how you react to them.

Air: gets cold

My immune system: seems suspicious enough

Histamine: allow us to introduce ourselves.

SciShow rocks. ive lived with allergies my entire life and they seem to get worse every year. i am so happy with how thorough they are.

Epinephrine isn't a form of adrenalin, it is adrenalin. It's simply another name for it.

Growing up I was allergic to absolutely nothing. After I had my daughter, BOOM! Seasonal allergies every spring. Itchy/watery eyes, runny nose, sneezing... It sucks. They seem to be fairly easily controlled with antihistamines and nasal decongestants luckily. I'd be really interested in learning more about how allergies develop during/after pregnancy.

Hearing him say yolk is the most vile thing I have ever experienced.

[zengrenouille]

I have a friend with so many allergies that the labs they recently started doing to help diagnose allergies was literally off of the charts. Her doctor doesn't even know how to begin treating her allergies. I've known her for 15 years, and I've never heard her real voice. She is constantly congested and nasally.

[SethWatersVlogs]

I've never been made so aware of the L in Yolk before.

[nicholepalmisano]

Nice video, but I would have liked to see something about allergies that have a delayed onset. I developed an allergy to shellfish in my mid 20s. I've never understood how I could have suddenly become allergic to something like that.

[LifeStyleTherapy]

Many things can trigger an allergic reaction. It happens when your body's defenses attack something that's usually harmless, such as pollen, animal dander, or food. The reaction can range from mild and annoying to sudden and life-threatening
I made a video in my channel about 8 Common Allergy Triggers you must know...you can watch it

[AValidPointUHave]

Wish you would have talked a bit more about season allergies and pollen allergies.
