When You Have Stomach Pain: Summary of Causes by Area and Warning Signs to Go to the Hospital

Understanding Abdominal Pain: 5 Key Q&A

Q1. When should I go to the emergency room for abdominal pain?

There are several warning signs to remember. If you experience sudden, severe pain like being stabbed, persistent vomiting, coughing up blood or seeing blood in your stool, or if your abdomen becomes hard and painful to touch, you should go to the emergency room immediately. Especially for women who may be pregnant, lower abdominal pain can be very dangerous due to the possibility of an ectopic pregnancy.

Q2. Can I guess the cause of pain just by its location?

Yes, it can provide very important clues. For example, pain in the upper right abdomen may indicate cholecystitis, pain in the lower left abdomen may suggest diverticulitis, and pain in the lower right abdomen may lead to suspicion of appendicitis. However, pain can also spread to other areas, and sometimes the whole abdomen can hurt, so location alone cannot provide a definitive diagnosis.

Q3. Why is lower abdominal pain dangerous when there is a possibility of pregnancy?

It is crucial to rule out the possibility of an ectopic pregnancy, which is the most dangerous emergency condition. This occurs when a fertilized egg implants in a place other than the uterus, such as the fallopian tube. If the tube ruptures as the embryo grows, it can lead to life-threatening internal bleeding. If you have lower abdominal pain along with vaginal bleeding or dizziness, you should go to the hospital immediately.

Q4. What symptoms suggest pancreatitis?

You may suspect pancreatitis if you experience severe pain near the sternum that radiates to the back. Diagnosis is typically made when this characteristic pain is accompanied by blood tests showing pancreatic enzyme levels (lipase/amylase) that are three times higher than normal.

Q5. Do I always get a CT scan when I go to the hospital?

No, it depends on the situation. If the cause is unclear or the pain is widespread, an abdominal CT scan provides the most information. However, if there is suspicion of a specific organ, such as in the case of upper right abdominal pain (gallbladder) or lower abdominal pain in women (uterus/ovaries), an ultrasound is often performed first.

Everyone experiences abdominal pain at some point. We may reach for digestive medicine thinking, "I must have overeaten," or rush to the bathroom, wondering, "Did I eat something bad?" While most abdominal pain passes lightly, some can be a serious warning sign from our body. Like a map in a fog, our body tries to indicate the source of the problem through the 'location' and 'nature' of the pain. But how should we interpret these signals? Today, we will unfold the map of our bodies, decode the various signals the abdomen sends, and learn when to stop exploring and send an urgent call for help.

Mapping Pain: Primary Classification Starting with “Where Does It Hurt?”

The first step in understanding abdominal pain is to identify the 'location of the pain.' Inside the abdomen, various organs occupy their specific places, making the area of pain a crucial clue in deducing the cause of the problem.

• Upper Right Abdomen: This is where the liver and gallbladder are located. If you experience bloating and pain after eating fatty foods, you may suspect gallstones or cholecystitis.
• Epigastric Area: This area contains the stomach, duodenum, and pancreas. Symptoms like burning pain and discomfort may indicate gastritis or a stomach ulcer, while severe pain radiating to the back can be a sign of pancreatitis.
• Lower Right Abdomen: This is the location of the appendix. Initially, pain may be around the belly button, then gradually move to the lower right abdomen, often accompanied by mild fever and nausea, suggesting a strong suspicion of appendicitis.
• Lower Left Abdomen: This area contains part of the colon, and diverticulitis is a common cause of pain here.
• Flank: If you experience sharp, stabbing pain in the flank that comes and goes, it is likely due to a stone lodged in the ureter, known as a kidney stone.

How to Assess: Key Steps in the Diagnostic Algorithm

When you arrive at the hospital, the doctor goes through several important steps to identify the cause of your abdominal pain.

The first thing they check for is 'red flags', which indicate potential emergencies. Next, they ask detailed questions about the location, nature, and accompanying symptoms of the pain, and perform a physical examination by palpating the abdomen to find the painful area. Blood tests or urine tests are conducted to check for inflammation levels or damage to specific organs, and all this information is combined to select the most appropriate imaging tests, such as CT or ultrasound, based on the suspected cause. For example, if there is a problem suspected in the gallbladder, uterus, or ovaries, an ultrasound is often performed first, while CT may be prioritized if the cause is unclear or if the entire abdomen is painful.

Episode: 20s College Student Lee Ji-eun's Appendicitis

College student Lee Ji-eun started feeling a slight pain around her belly button the night before. "I thought it was just indigestion and took some digestive medicine, but when I woke up in the morning, the pain had moved to my lower right abdomen, and I felt a throbbing sensation with every step." Noticing something was off, she visited the hospital and was diagnosed with acute appendicitis, undergoing surgery that very afternoon. "The fact that the pain moved was a really characteristic sign," she said.

Home Management and Prevention

If there are no warning signs and the abdominal pain is mild, how should you manage it at home?

First, it's important to fast for a day or consume soft foods like porridge to soothe your stomach. Staying hydrated is essential, but you should avoid greasy or spicy foods and alcohol. Taking painkillers indiscriminately can mask the cause of the pain, which is not advisable. If the pain worsens, or if you develop a fever or persistent vomiting, you should go to the hospital immediately.

To prevent abdominal pain in general, maintaining regular eating habits and a balanced diet is key. Particularly, consuming plenty of fiber-rich vegetables and fruits can greatly help in preventing diverticulitis or constipation-related abdominal pain. Avoiding excessive drinking or overeating, and staying well-hydrated to prevent kidney stones are also important habits.

Episode: 50s Office Worker Park Cheol-min's Pain

Park Cheol-min, a 50s office worker who typically enjoyed a meat-heavy diet and frequent drinking, began to feel sharp pain and fever in his lower left abdomen a few days ago. Thinking it was just simple gastroenteritis, he tried to endure it, but as the pain worsened, he eventually went to the emergency room. A CT scan revealed he was diagnosed with 'complicated diverticulitis with perforation' and required emergency surgery. After discharge, he reflected, "My lifelong eating habits ultimately created this illness," and he is now making an effort to include more vegetables and fruits in his diet.

In-Depth Exploration 1: Ectopic Pregnancy, Why Is It the Top Emergency in Gynecology?

When a woman of childbearing age complains of sudden lower abdominal pain, the worst-case scenario that comes to a doctor's mind is 'ruptured ectopic pregnancy.' An ectopic pregnancy occurs when the fertilized egg implants not in the normal location of the uterine lining but in an abnormal location like the fallopian tube.

The problem is that the fallopian tube is not a space where a baby can grow. As the fertilized egg grows, it stretches the thin walls of the fallopian tube until, at some point, it can 'burst.' This can lead to massive internal bleeding, putting the patient in life-threatening shock due to excessive hemorrhage. Therefore, when a woman who may be pregnant experiences sudden lower abdominal pain accompanied by vaginal bleeding, dizziness, or, in severe cases, pain radiating to the tip of the shoulder, urgent surgery may be necessary. This is a representative case showing how dangerous it is to delay testing due to 'what if' thoughts.

In-Depth Exploration 2: The Warning of Westernized Diets, Diverticulitis

One of the conditions suspected when experiencing localized pain and mild fever in the lower left abdomen is 'diverticulitis.' 'Diverticula' are small pouches that protrude outward from weak points in the colon wall, and when waste materials like stool get trapped in these pouches, inflammation occurs, leading to diverticulitis.

This condition, once common in the West, is now rapidly increasing in Asian countries. The primary cause identified is 'westernized diets.' Diets high in processed foods and red meats, which are low in fiber, can lead to constipation, increasing pressure inside the colon and making diverticula more likely to form. Most diverticulitis cases improve with antibiotic treatment, but in severe cases, complications like perforation or abscess may require surgery. Pain in the lower left abdomen can be a warning sign from our body to reconsider our eating habits.

FAQ: Clinical Snapshots by Situation

Q. I ate greasy food and now my upper right abdomen hurts.

This is likely related to a gallbladder issue. When the gallbladder contracts to digest greasy food, if gallstones block the bile duct or if inflammation occurs, it can lead to pain. The pain may also radiate to the right shoulder or back.

Q. I have sharp pain in my flank that comes and goes.

This is a typical symptom of kidney stones. Stones formed in the kidneys can cause severe pain as they travel down the narrow ureter. The pain can be so intense that it leads to sweating and nausea.

Q. I feel a tightness in my epigastric area and the pain radiates to my back.

You may suspect acute pancreatitis. Common causes include excessive drinking or gallstones. Bending forward can sometimes relieve the pain. Heart problems can also present as pain in the epigastric area, so don’t assume you’re safe just because you don’t have chest pain.
