Is it normal to be sick this often?

Eat foods that strengthen your immune system and avoid ones that weaken them. Highly processed foods weaken your system. Avoid refined sugar, alcohol, and fats. You may also have an allergy to something that is weakening you. Cut back on dairy when you are congested. Dairy causes that phlegm to thicken- gross.

I used to be like that a doctor perscribed me with an alergy medication it has helped 100%

I get sick like every two weeks, but apparently there's nothing wrong with me. Just a little low iron issue but that's it!

I was like that before I had my gallbladder out. Seriously get yourself checked for an underlying cause.

This is too often. You should talk to a doctor about this. You may have some underlying condition that is dampening your immune system and making you more susceptible to getting sick.

I was like that as a kid before I got my tonsils removed.
