Sour Stomach – Causes, Symptoms, And Remedies

Symptoms Of A Sour Stomach

The symptoms of a sour stomach are closely connected to two common gastroesophageal conditions, namely acid reflux and indigestion.

Any severe disturbance in the upper digestive tract usually exhibits the following symptoms:

Belching or Burping

It usually occurs when the stomach distends or expands because of too much or swallowed air. Burping is produced while releasing the excess air in the stomach via the mouth.


Any kind of severe irritation in the upper digestive tract can make you feel nausea. When the foods you eat do not properly go through the digestive tract, your stomach gets upset and develops nausea feeling.


The presence of an excess amount of gastric acid reaching up to your esophagus causes a burning sensation in the chest and throat.


It is the uncomfortable feeling of fullness, tightness, or swelling in the abdomen, which is usually caused by a mixture of air and food in the stomach.

Stomach Ache

One of the most common symptoms of a sour stomach is abdominal pain. It may last for a few hours and can cause severe pain if the stomach’s condition is really bad.


Regurgitation is the forceful expulsion of stomach contents backward through the esophagus and to the mouth. Regurgitation is an important mechanism of the body to get rid of noxious substances. This symptom is usually experienced by persons with an upset stomach or heartburn.


Constipation can happen because of eating foods with poor fiber and liquid content. Processed foods, red meat, and fatty foods can also result in constipation.

Other Symptoms

People who are suffering from a sour stomach could also experience symptoms like stress, mild fever, headache, physical weakness, and drowsiness.

What Causes a Sour Stomach?

Acid reflux (GERD) is the incidence of stomach acid entering the esophagus.  It is characterized by a burning pain, known as heartburn, which has the epicenter in the lower chest area of the body.

GERD syndrome is caused by overeating, excess stomach acid, and reduced tonicity of the sphincter.

Dyspepsia or indigestion causes belching, nausea, stomach pain, and bloating. Indigestion usually subsides by itself after a day.
