The reason why my stomach hurts suddenly

If you are experiencing stomach, pituitary, or back pain, you should find out the reason and deal with it.

Stomach, stomach pain and stress

Stress is closely related to gastric pain and can lead to increased gastric acid secretion, reduced blood flow, and decreased gastric mucus secretion due to disturbances in the autonomic nerves, delaying tissue recovery. Additionally, prolonged stress may cause deterioration in stomach and intestinal movement, increased digestive tract pressure, and inflammation or ulcers accompanied by pain.

Causes of stomach pain, pituitary pain, back pain

<reflux esophagitis>

The cause of stomach pain is reflux esophagitis? It is a condition in which gastric acid reflux into the esophagus is repeated for various reasons, causing inflammation in the mucous membrane of the esophagus.
It is common to experience pain in the stomach at night on an empty stomach. It is not a severe pain, but it is characterized by pain mixed with the discomfort of heartburn.

<functional dyspepsia>

Stomach pain can be caused by a condition called functional dyspepsia. In this condition, a camera test of the stomach shows no abnormalities in the mucous membrane, but people may experience chronic pain or bloating. The pain is usually felt in the upper abdomen, in an area known as the pit of the stomach. The symptoms may come and go without clear reasons and can include pain or burning in the stomach, bloating, excessive belching, nausea after eating, and an early feeling of fullness when eating. It’s important to note that functional dyspepsia is a common condition, and its exact cause is not fully understood. Treatment options for functional dyspepsia include patient education about the nature of the disorder, medication use for a limited duration, and interventions like proton-pump inhibitors and Helicobacter pylori eradication.

<esophageal cancer>

Esophageal cancer is a condition where cancer cells have multiplied in the esophagus, the long tube that connects the throat to the stomach. This type of cancer is characterized by symptoms such as tightness in the chest while swallowing food, back pain, coughing, sore throat, hoarse voice, and weight loss. However, in the early stages, there are typically very few symptoms.

Esophageal cancer can affect anyone but is more common in men than in women. It ranks as the sixth most common cause of cancer-related deaths globally. The risk factors for developing esophageal cancer include smoking, heavy alcohol consumption, chronic heartburn or acid reflux, obesity, and certain genetic factors.

The most common symptoms of esophageal cancer are difficulty swallowing, unintentional weight loss, chest pain or burning, worsening indigestion or heartburn, coughing, and hoarseness. Early-stage esophageal cancer may not cause noticeable symptoms, which is why regular check-ups and screening are essential, especially for those with risk factors such as Barrett’s esophagus.

If you experience persistent signs or symptoms that concern you, it’s crucial to make an appointment with your doctor for a thorough evaluation. Detecting esophageal cancer early increases the likelihood of successful treatment and improved outcomes.

<acute gastritis>

Acute gastritis is a sudden inflammation of the stomach lining, also known as the gastric mucosa. It can be triggered by various factors such as stress, certain medications like pain relievers, and excessive alcohol consumption. The condition may cause symptoms like sudden heartburn, nausea, vomiting, and fever. It is essential to note that acute gastritis is different from chronic gastritis, which is a long-term condition that develops gradually.

Acute gastritis can be caused by injury, bacterial or viral infections, and ingestion of irritants like alcohol, NSAIDs, steroids, or spicy food. The inflammation in the stomach lining may result in symptoms such as loss of appetite, stomach pain, black stools, and a full feeling in the upper abdomen after eating. Some symptoms, like vomiting blood that resembles coffee grounds, may indicate a bleeding ulcer.

The condition usually lasts for a short period and can resolve on its own within a few days or weeks. However, if symptoms persist for a week or longer, it is essential to seek medical attention. Acute gastritis can sometimes progress to chronic gastritis if left untreated, leading to potential complications such as stomach ulcers and gastrointestinal bleeding.

It’s crucial to identify and address the triggers of acute gastritis to manage the condition effectively. Avoiding known irritants, taking prescribed medications as directed by a healthcare provider, and adopting a healthy lifestyle can help prevent and alleviate symptoms of acute gastritis.


Duodenitis is inflammation of the lining of the duodenum, which is the first part of the small intestine located just after the stomach.
Common symptoms of duodenitis include burning or cramping pain in the stomach and back, gas or bloating, nausea, and a full feeling after meals.
The primary cause of duodenitis is infection by H. pylori bacteria, but it can also be triggered by long-term use of certain medications like NSAIDs, alcohol consumption, smoking, celiac disease, or Crohn’s disease.
Diagnosing duodenitis involves tests such as upper endoscopy with biopsy, blood, stool, gastric biopsy, or breath test to detect H. pylori or other germs.
Treatments for duodenitis may include antibiotics to kill H. pylori, medications to reduce stomach acid production, adopting a gluten-free diet if celiac disease is the cause, and lifestyle changes like avoiding alcohol and quitting smoking.
With proper treatment, most cases of duodenitis can be cured, but in some rare cases, it may become chronic or progress to a duodenal ulcer, requiring further checkups and treatments.

<stomach cancer>

Gastric cancer is a condition where cancerous cells form in the lining of the stomach, and it can cause pain in the upper part of the stomach known as epigastric pain.
In Korea, the number of deaths from gastric cancer is increasing, and it is more common in men. The main symptoms of gastric cancer include pain in the pit of the stomach, discomfort in the chest, loss of appetite, and nausea.
Gastric cancer is often discovered at an advanced stage when symptoms appear, but in early stages, there may be no symptoms at all.
Regular stomach camera inspections are crucial for early detection of gastric cancer.
Stomach cancer can occur in any part of the stomach, but most cases in the U.S. happen in the gastroesophageal junction.
The risk factors for stomach cancer include smoking, family history, H. pylori infection, stomach inflammation, and certain dietary habits.
Symptoms of stomach cancer can include difficulty swallowing, bloating, feeling full after eating small amounts, heartburn, nausea, unintentional weight loss, and vomiting.
To diagnose stomach cancer, doctors may perform an upper endoscopy, biopsy, imaging tests like CT scan or barium swallow, and additional tests to determine the extent of cancer.
Treatment options for stomach cancer include surgery, chemotherapy, radiation therapy, targeted drug therapy, and immunotherapy.
Regular check-ups and early detection are essential to improve outcomes for people with stomach cancer.

<chronic gastritis>

Chronic gastritis is when the stomach lining gets inflamed due to an infection with H. pylori or other causes. It can cause pain and discomfort in the stomach and may lead to long-term inflammation in the entire stomach.
The main symptoms of chronic gastritis are persistent pain around the stomach area, indigestion, bloating, nausea, vomiting, and loss of appetite.
Gastritis can occur suddenly (acute) or develop gradually over time (chronic). Chronic gastritis is more difficult to get rid of but usually improves with treatment.
The stomach lining produces acid and enzymes to digest food and protect from infections. Gastritis happens when the protective layer is damaged, allowing stomach acid to irritate the lining.
Chronic gastritis can be caused by bacterial infection (H. pylori), excessive alcohol consumption, drug use, stress, or certain illnesses.
Chronic gastritis is categorized into three types: Type A caused by the immune system attacking stomach cells, Type B caused by H. pylori infection, and Type C caused by chemical irritants like NSAIDs or alcohol.
Symptoms of chronic gastritis may include upper abdominal pain, indigestion, bloating, nausea, vomiting, belching, and loss of appetite.
Chronic gastritis can lead to other health problems like the growth of gastric polyps or the development of peptic ulcers in the stomach.
Lifestyle factors like high-fat, high-salt diets, smoking, and long-term alcohol consumption can increase the risk of chronic gastritis.
If you experience stomach irritation for more than a week or have symptoms of chronic gastritis, it’s essential to see a doctor for evaluation and appropriate treatment.


Cholecystitis is a condition where the gallbladder’s lining becomes inflamed. This inflammation can happen suddenly (acute cholecystitis) when a stone blocks the cystic duct or due to an injury to the gallbladder’s wall. If the inflammation occurs repeatedly, it leads to thickening of the gallbladder wall, which is known as chronic cholecystitis.

Characteristic symptoms of cholecystitis include severe pain in the upper right abdomen and back after eating. Additionally, a person may experience nausea, vomiting, and fever.

If someone has a fever, they should seek urgent surgery called cholecystectomy. It’s important to visit a hospital that can perform this surgery, especially when there’s a fever.
