What cause loss of appetite after eating food?

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Basically, when you swallow, the vagus nerve or esophagus can trigger the heart to beat fast for a short while; some people are very sensitive to this.

The vibrating feeling in the whole body is probably from the sudden adrenaline surge or palpitations. Loss of appetite is likely because you are scared to eat now.

The symptoms are due to swallow-induced supraventricular tachycardia (SVT), vagal reflex-mediated arrhythmia, an anxiety response triggered by swallowing, or, less commonly, reflux esophagitis irritating the vagus nerve.

To investigate further, the following tests are recommended -

1. A baseline ECG (electrocardiogram), a 24-hour Holter, or an event monitor during meals to capture the rhythm.

2. Echocardiography to rule out structural heart problems.

3. Basic thyroid and electrolyte profiles.

Differential diagnoses include-

1. Swallow syncope.

2. Atrial tachycardia triggered by swallowing.

3. Severe acid reflux with autonomic symptoms.

4. Panic attacks mimic palpitations.

The most probable diagnosis is swallow-induced paroxysmal tachycardia or a vagally mediated arrhythmia.

So your treatment includes -

• Get the rhythm documented first (Holter is key).

• If it is an arrhythmia, treatment can include beta blockers or, in rare cases, ablation of the trigger pathway.

• If it is reflux-related, antacid therapy (PPI - proton pump inhibitors) can help reduce vagal irritation.

• In the meantime, patients should eat slowly, chew thoroughly, and avoid very cold or carbonated drinks.

Preventive steps include smaller, softer meals, avoiding caffeine, alcohol, and spicy food, and staying well hydrated to reduce palpitations.

Regarding follow-up, a cardiology consultation for Holter monitoring is strongly advised, and urgent care should be sought if dizziness, fainting, or chest pain occurs.

I hope this helps.

Thank you and take care.

Regards.
