Apparently, the cause of the stomach stinging is caused by several things. One of them could be an indication of GERD disease, you know!

Well, this time we will discuss the causes of stomach stinging even though you have eaten and how to deal with it.

Causes of Stomach Stinging After Eating

When you eat late, you may experience symptoms of abdominal pain such as an ulcer or dyspepsia.

This condition triggers discomfort in the upper abdomen and makes a person feel full quickly, even though he has just eaten a little.

To deal with it, people will usually eat immediately as soon as they feel that their stomach is uncomfortable.

However, there are certain conditions that sometimes make people wonder. Although they have eaten, why do their stomachs still feel sore, huh?

This can be caused by several things, including:

1. Indigestion

The most common cause of stomach stinging is indigestion. Usually, the stomach will hurt or experience bloating.

This condition is caused by 2 things, namely the acid content in the stomach and the type of food/drink consumed.

The stomach contains acidic compounds that destroy food in the digestive system.

Although it is relatively safe, sometimes this content can irritate the walls of the stomach and cause indigestion.

Meanwhile, the types of foods and drinks that can trigger indigestion include:

  • Fatty foods.
  • Caffeine.
  • Drinks with high sugar content.
  • Alcohol.

Caffeine can be found in coffee, tea, soda, and energy drinks. The content is also different, namely:

  • Brewed coffee size 237 ml contains 96 mg of caffeine.
  • Brewed black tea size 237 ml contains 47 mg of caffeine.
  • Cola size 237 ml contains 22 mg of caffeine.
  • Energy drink size 237 ml contains 71.9 mg of caffeine.

The safe limit of adult caffeine consumption can reach 400 mg/day. However, this amount can change depending on each person's caffeine tolerance.

In addition to caffeine, stomach stinging is also caused by alcohol because this drink can cause bloating.

2. Food Allergies

You need to pay attention to the content of the food to be eaten. The reason is, that foods that contain allergenic ingredients can trigger stomach stinging.

More severe side effects include itching and convulsions.

Some of the ingredients that are generally avoided by many people are gluten, wheat, lactose, and seafood.

If the allergy worsens, this can cause celiac disease, which is one of a digestive disorders.

Celiac disease is generally caused by gluten allergies that are often found in wheat.

Symptoms include abdominal pain, constipation, diarrhea, and bloating.

3. Irritable Bowel Syndrome (IBS)

The next cause of stomach stinging is irritable bowel syndrome (IBS) which attacks the digestive system.

IBS can cause stomach cramps and bloat. This symptom can also occur for months, you know!

Meanwhile, no cure has been found that can cure this disease.

But you can minimize their symptoms by changing a healthier lifestyle, for example:

  • Eat slowly.
  • Avoid fatty and fast foods.
  • Reduce alcoholic beverages or those with high sugar content.
  • Eat on time.
  • Regular exercise.


Acid reflux causes acidic fluid in the stomach to rise into the esophagus ducts.

This causes discomfort such as burning in the chest or called heartburn.

You also feel like the food that has been swallowed back into the esophagus.

If you experience acid reflux at least 2 times a week, you may have GERD (gastroesophageal reflux disease).

Some of the bad habits that make this condition worse include:

  • Eat too much.
  • Lie down immediately after eating.
  • Overweight.
  • Snack before bedtime.
  • Eat spicy, fatty, and acidic foods.
  • Drink alcohol, coffee, tea, and carbonated drinks.

How to Overcome Stomach Stinging after Eating

To overcome stomach stinging due to food allergies, you need to avoid the ingredients that cause these allergies.

If you are not sure what foods make you allergic, you can do an allergy test with a nutritionist at the hospital.

Meanwhile, if the stomach is sore due to GERD disease, it can be treated medically by taking tests, including:

  • Upper endoscopy, which is inserting a flexible hose equipped with a camera into the esophagus to see the condition of the esophagus.
  • Ambulatory acid (pH) probe test, in which a flexible hose is inserted into the esophagus to find out when and how long stomach acid appears there.
  • X-ray in the upper digestive system, where you downed the drink or swallowed the pill so that the doctor could know the movement of the drink/pill in the esophagus and whether it was narrowed or normal.
  • Esophageal manometry, that is, calculates the contraction of muscles in the esophageal part when swallowing.
  • Transnasal esophagoscopy, which is to insert a flexible tube with a camera through the nostrils, then go down the esophagus to see if there is any damage or not.

That's a complete explanation of stomach stinging, its causes, and how to overcome it. Hopefully, this information is helpful for you and your family!
