I often start coughing right after the meal, which oftentimes ends up in vomiting. A small amount of food feels like I have eaten a lot. Please help.

Question

Having a bit of a cough after eating isn?t necessarily a big deal, but when you develop a chronic cough after every meal, it can be very frustrating and annoying, or worse, it could be a sign of a serious health problem.
Everybody coughs from time to time; coughing is our body?s way of clearing out irritating substances from the throat or airways.
It could be the result of something that you?ve eaten or inhaled that irritates the throat, or maybe you drank something that triggered a reaction. In any case, coughing can occur, as an attempt by the body to remove the substance.
A number of health conditions can cause a chronic cough after eating, including allergies, infections, and various gastrointestinal disorders.
1. Allergies
If you experience a cough after eating spicy food, then it?s possible that food allergies are to blame. A number of common bodily reactions may occur if you?re exposed to an allergen or an irritant, including a stuffy nose, watery eyes, and coughing. What?s really happening is that your immune system is responding after being exposed to a trigger; coughing is its way of dealing with it. Many people experience a cough after eating dairy, particularly if they are lactose intolerant. However, if you have a cough after eating ice cream, dairy isn?t always to blame?cold foods can also trigger this reaction in some people.
2. Infections
If you have an infection in your esophagus or larynx, then you may experience coughing after eating. Infections can cause inflammation in these areas of the throat, which can cause them to malfunction, and coughing may be a symptom of the inflammation. Bacteria, viruses, and fungi can all cause infections, and they require medical treatment to be corrected.
3. GERD
Gastroesophageal reflux disease (GERD) is also called acid reflux, and it?s a common cause of a chronic cough after eating (1). With GERD, the lower esophageal sphincter (which is a ring-shaped muscle that keeps the top of the stomach closed) does not function properly and allows partially digested food and stomach acid to rise into the esophagus. This acid causes irritation, which can lead to coughing, as well as other symptoms including heartburn. If you have GERD coughing after eating, then you may also have indigestion, malnutrition, and bloating.
4. Dysphagia
A persistent cough after eating may also be caused by difficulty swallowing, a condition known as dysphagia. The act of swallowing food and beverages slows and becomes harder to accomplish; sometimes it becomes impossible. It may appear that the body is rejecting the substances, with coughing and the gagging reflex that occurs during and after eating.
Dysphagia may present symptoms of choking while eating, regurgitation of food through esophageal or nasal passages, excessive drooling, or the sensation of having food stuck in the middle of the throat.
5. Asthma
With asthma, coughing with eating may result from either an allergy to the food or complications of the lung disease itself. As a chronic illness, asthma can irritate the airways, causing persistent coughing when eating. Some food and drinks contain sulphites, an additive that triggers an allergy response in some people, especially asthmatics.  
This may cause breathing difficulty along with the common asthma symptoms of wheezing, chest tightness, and early morning or late-night coughing episodes.
6. Aspiration Pneumonia

Unlike traditional pneumonia, which is typically caused by a viral or bacterial infection, aspiration pneumonia refers to food, drink, or saliva accidentally entering the lungs. This often occurs when eating or drinking too quickly or while vomiting.
Your body will respond by triggering constant coughing to stop the unfamiliar entry into the lungs. This usually signals the lungs to prevent the particles or liquid from entering. If not stopped, bacteria may develop, and aspiration pneumonia evolves. 
Symptoms may include a wet cough; heartburn; excessive saliva production; or immediate fever, coughing, and congestion after eating.
