GERD means gastro esophageal reflux disease. Some doctors also call it GORD or Acid Reflux.

It is the most common cause for coughing after eating and heart burn. For this reason sometimes cough after food is called as acid reflux cough.

As the name suggests, a reflux action in the stomach area upwards causes coughing after eating.

Semi-digested food from your stomach re-enter your food pipe when the muscles at the entry to your stomach do not close as they should after eating  or re-open during digestion.

When semi-digested food comes back into your lower esophagus, it causes irritation in your throat. When this happens, your brain causes a reflux action that results in coughing.

Cough due to acid reflux generally occurs after eating but in some cases, it may also occur during eating.

Some simple tips to deal with GERD cough include:

  • Use a bed or pillow customised for GERD relief 
  • Avoid over eating; instead have smaller meals throughout the day
  • Avoid going to bed soon after eating a meal; give it a couple of hours after a meal so you do not go to bed on a full stomach.
  • Try to eat slowly at a leisurely pace and chew all food very well before swallowing
  • Identify what foods trigger cough after eating in your case and stay away from such foods
  • Try to bring your body weight to a healthy level; lose weight if needed and avoid being obese
  • Try and drink more water throughout the day and keep your body well-hydrated

  1. Allergy

Coughing After Eating Allergy

Have you ever wondered if your body quiet does not like certain types of food or certain kinds of cooking?

That could be a food allergy. Food allergy can make you cough after you eat. 

Allergy  could be another reason why you cough after eating. It could be that certain foods or types of foods or the way food is cooked or the temperature of the food that can cause coughing after eating.

Before you eat such food next time, you may find it helpful to know what allergy means and how to suppress a cough caused by allergy. You may be allergic to certain foods or the way food is cooked.

In simple terms, allergy is a damaging immune response by your body to some foods. When you eat an allergen, your body perceives the food as a danger and produces histamine. Histamine causes allergic cough and other allergy symptoms. Allergic cough due to food can be mild or very severe.

Your body may be hypersensitive to some foods. People of any age can suffer from an allergy but it is more common in children.

Some children find their allergy disappearing as they grow into adults whereas, some adults start to show allergy symptoms to certain foods to which they were not allergic during childhood.

Most common food items that can trigger an allergic reaction in humans are nuts, fruits, shellfish, eggs and milk. The best way to deal with an allergic cough is to keep away from such foods that may cause an allergy.

You can see a doctor and seek medical advice when you feel you are being allergic to certain foods. Doctors can prescribe you medicines like antihistamines or decongestants or steroids.

In some cases, doctors may recommend immunotherapy to deal with coughing after eating.

Immunotherapy means you get exposed to an allergen in a controlled manner over a long period of time by which your body gets used to the allergen and does not react with a severe response such as a cough.

  1. Infection of Esophagus or Larynx

Infection of esophagus and larynx can cause inflammation in the areas through which food passes when you swallow. This may result in malfunction of the parts that help you swallow food.

As a result you may cough while you eat. This may even make you cough after you eat.

Infections and inflammations of esophagus and larynx can sometimes cause more serious problems than just coughing after eating.

These include difficulty in swallowing, severe irritation or even choking.

If are coughing after eating or you see any of these symptoms or you know you have such an infection, you must see a doctor as soon as possible for a medical advice. Your doctor may offer you some antibiotics.

You must use antibiotics only when necessary and in the right dosage for the right duration. Only a qualified doctor can help you with how to suppress a cough with antibiotics.

Dysphagia is a condition that causes discomfort in swallowing.

Other symptoms of dysphagia include the below. 

  • choking when eating or drinking
  • bringing food back up sometimes through the nose
  • sensation that food is stuck in your throat or chest
  • persistent drooling of saliva

If you see any of these along with coughing after eating, you must see a doctor.

If neglected, dysphagia can lead to weight loss and repeated chest infections in the long term in addition to  difficulty in swallowing.

Dysphagia is generally caused by another inherent health condition such as stroke, head injury, dementia, mouth cancer, oesophageal cancer or GERD.

Treatment of dysphagia includes:

  • changing the consistency of the food and drink thus making it easier to swallow
  • feeding from nose or direct into stomach via a tube
  • placing a stent in the esophagus to widen the food passage by surgery
  1. Asthma

Asthma is a very common condition that may cause difficulty in breathing.

It may not be a direct reason for coughing after eating. An allergic reaction or an infection of the airways that is related to your asthma is what causes coughing after eating.

If you have asthma and cough after you eat, you may want to find out if they both are related. You may refer yourself to a chest specialist.

A chest specialist would conduct some tests on you to determine if you are coughing after eating because of asthma.

If asthma is not the cause for your cough after you eat, he may look for other causes. If your cough with food is found to be a result of your asthma, doctors may do something to treat your asthma.

Common drugs used for asthma are in the form of steroids.

  1. Aspiration Pneumonia

Sometimes as you swallow food, accidentally food enters into lungs. This might happen either when you eat or drink something in a hurry or during a vomit.

In either of these cases, you may end up coughing.

So, when food or drink enters your lungs, your body responds with a cough to expel the foreign material. This is what happens in coughing after eating due to aspiration pneumonia.

So if you are coughing after eating, and you feel food or drink entered your lungs or respiratory tract, you must see a doctor to check out if it is aspiration pneumonia.

A doctor can help you with medical advice to get rid of your coughing after eating due to aspiration pneumonia.
