Most cases of dysphagia are caused by abnormalities in the brain. But as age increases, various muscles weaken and as a result, the force of swallowing decreases, which can cause swallowing problems or a feeling of food stuck in the throat.
If you try to observe carefully When our tongue hurts, it still feels like food is stuck in our throat and we have to swallow it repeatedly or swallow water.

Food that remains after swallowing is one of the causes of aspiration pneumonia. 

Why is there food stuck in my throat?

In fact, there are 2 most common locations where the stuckness in the throat is found: in the valecula area. (It is the part between the base of the tongue and the epiglottis) and the position of the piriform, which is the position where the fish bones tend to stick often.
Normal when swallowing The food will stay in the valecula area first to continue the swallowing process. Uh oh!!! Don’t think that it will last very long. This is because swallowing normally only takes place in 1-2 seconds. So it’s stuck for a moment. As soon as the food is swallowed, it will go down completely, leaving nothing left behind.

But if

Weak tongue muscles During swallowing, the base of the tongue cannot touch the back of the pharynx.

The elevation of the larynx is reduced. This is to observe that it is normal when swallowing. We will see the Adam’s apple move. It is caused by the lifting of the larynx. If it is not moved or moved little, it will cause swallowing to become stuck and food to remain.

How to manage it?

If swallowing is difficult, drink water (liquid wash) or swallow harder (effortful swallow).

Bending your neck when swallowing helps reduce food that stays in the valence.

If it is caused by sarcopenia in the elderly, they must take care of their food to meet their needs, especially protein.
