Over Active Gag Reflex when swallowing anything-cant eat anything

Is this something that recently started, or is it something that's been a problem for some time?

Is there a particular type of food or does all food make you gag?

Do liquids make you gag as well?

You say you are a picky eater. What food do you eat and what foods can you eat without gagging? 

The more information you provide, the better the chances we can help you.

i like liquids and soft foods, that i can eat without gagging,if i try something that i dont like or the one which is not soft,i feel hard to swallow and i gag specially in the morning, i like shakes,the more i need to chew and focus on food the more i gag
and in summer i eat less,
i really want myself to eat like a normal person

I believe a lot of the problem stems from a learned behavior when you were younger. There were foods you didn't like because of the taste. You learned to associate the taste with the texture. You learned that when you felt certain textures in food, primarily a rough texture, you could gag to prevent yourself from having to eat them. Texture has become the signal for the gag reflex as an adult. You instinctively gag when the texture is not soft and liquid like.  

This behavior can be unlearned. Try eating small bites of the undesirable foods. Chew them into very mushy liquid states before swallowing. To make them more palatable and tasty, add cheese, salt, or some type of sauce before eating. It will take time. Stick with it and you can over come the problem.
