Stomach pain can happen in different parts of the abdomen, and the location may offer clues about its cause. Pain in the upper abdomen may be related to acidity or the gallbladder, while pain in the lower abdomen can sometimes point to bowel, urinary or appendix-related problems.

The location alone cannot confirm a diagnosis. How the pain begins, how long it lasts and whether you have other symptoms are equally important. Understanding these differences can help you explain your symptoms to a doctor and recognise when medical attention is needed.

1. Upper Middle Abdominal Pain

Pain in the upper middle part of the abdomen, just below the breastbone, is known as epigastric pain. It may feel like burning, discomfort, pressure or a dull ache.

Common causes include:

• Acidity or acid reflux: May cause burning discomfort, sometimes with a sour taste in the mouth.

• Gastritis: Inflammation of the stomach lining that can cause upper abdominal discomfort, nausea or indigestion.

• Peptic ulcers: Open sores in the lining of the stomach or the upper small intestine.

• Pancreatitis: Inflammation of the pancreas that can cause severe upper abdominal pain, sometimes spreading to the back, with nausea or vomiting.

Mild, occasional discomfort may be related to indigestion, but persistent or severe pain should not be ignored. Sudden, intense pain, particularly with repeated vomiting, needs urgent medical assessment.

2. Upper Right Abdominal Pain

Pain below the right side of the ribs can sometimes be associated with the gallbladder or liver.

Possible causes include:

• Gallstones: Pain may occur after meals, particularly fatty meals, and can spread towards the right shoulder or back.

• Gallbladder inflammation: Pain may be persistent and accompanied by fever, nausea or vomiting.

• Liver-related conditions: Some liver problems cause discomfort in this area, although many liver conditions produce no pain in the early stages.

Seek prompt medical attention if upper-right abdominal pain occurs with fever, yellowing of the eyes or skin, or persistent vomiting. These symptoms may indicate a condition that requires timely treatment.

3. Upper Left Abdominal Pain

The upper left side of the abdomen contains parts of the stomach, pancreas, spleen and bowel. Discomfort in this region can have several causes.

Possible explanations include:

• Gastritis or stomach ulcers.

• Gas or indigestion.

• Pancreatic conditions.

• Problems involving the spleen, particularly after an injury.

Pain in the upper left abdomen can occasionally come from outside the digestive system, including the chest. Sudden pain after an injury or abdominal pain accompanied by chest pressure, breathlessness or sweating requires urgent evaluation.

4. Pain Around the Belly Button

Pain around the navel may occur with digestive problems, intestinal infections or constipation. In some cases, it can be an early sign of appendicitis.

Common causes include:

• Gastroenteritis: May cause cramping, diarrhoea, nausea or vomiting.

• Constipation: Can lead to abdominal discomfort, bloating and difficulty passing stools.

• Intestinal problems: Bowel inflammation or obstruction can cause pain and changes in bowel movements.

• Early appendicitis: Pain may begin around the navel before moving towards the lower right abdomen.

If pain around the belly button becomes progressively worse, moves to the lower right side or occurs with fever and vomiting, seek prompt medical assessment.

5. Lower Right Abdominal Pain

Lower-right abdominal pain deserves particular attention because it is a common location for appendicitis.

Possible causes include:

• Appendicitis: Pain may start near the navel and move to the lower right side, often becoming more intense over time.

• Kidney stones: Pain may spread from the side or back towards the lower abdomen or groin.

• Bowel-related conditions: Constipation and intestinal inflammation can also cause discomfort.

• Gynaecological conditions: Ovarian cysts and other pelvic conditions may cause lower-right pain in women.

Appendicitis can worsen if treatment is delayed. Seek urgent medical evaluation for worsening lower-right abdominal pain, especially when accompanied by fever, nausea, vomiting or loss of appetite.

Do not wait for every typical symptom to appear before seeking care.

6. Lower Left Abdominal Pain

Pain in the lower left abdomen may be related to the large intestine, urinary tract or pelvic organs.

Possible causes include:

• Constipation: Often associated with bloating and infrequent bowel movements.

• Diverticulitis: Inflammation or infection involving small pouches in the colon, which can cause persistent pain and fever.

• Kidney stones: May cause pain that spreads towards the groin, sometimes with blood in the urine.

• Pelvic conditions: Ovarian or other gynaecological problems may cause pain in this region.

If the pain persists, repeatedly returns or occurs with fever, blood in the stool or changes in bowel habits, arrange a medical consultation.

7. Lower Central Abdominal Pain

Pain in the lower middle abdomen, just above the pubic bone, is often described as pelvic or suprapubic pain.

Possible causes include:

• Urinary tract infection: May cause discomfort with frequent urination, burning or an urgent need to pass urine.

• Bladder conditions: Can cause pressure or pain as the bladder fills.

• Constipation: May produce discomfort in the lower abdomen.

• Gynaecological conditions: Menstrual cramps and other pelvic conditions can cause pain in this area.

Seek medical advice if the pain is persistent or associated with painful urination, blood in the urine, fever or unusual vaginal bleeding. Severe pelvic pain during pregnancy or when pregnancy is possible requires urgent assessment.

8. Generalised Abdominal Pain

Sometimes pain affects the entire abdomen rather than one specific area. It may feel like cramps, bloating, pressure or widespread tenderness.

Possible causes include:

• Gastroenteritis or food-related illness.

• Gas and constipation.

• Widespread intestinal inflammation.

• Bowel obstruction or other serious abdominal conditions.

A serious condition may begin with pain in one area and later spread across the abdomen. Severe pain with a hard, swollen or very tender abdomen is particularly concerning.

Seek emergency medical care if abdominal pain is sudden and severe, spreads rapidly or occurs with repeated vomiting, fainting or significant abdominal swelling.

Warning Signs You Should Never Ignore

Regardless of where the pain occurs, seek urgent medical attention if you experience:

• Sudden or severe abdominal pain.

• Pain that steadily worsens over several hours.

• A hard or extremely tender abdomen.

• Fever accompanied by significant abdominal pain.

• Persistent vomiting or an inability to keep fluids down.

• Blood in vomit or stools, or black, tarry stools.

• Fainting, confusion, severe dizziness or a rapid heartbeat.

• Significant abdominal pain during pregnancy or when pregnancy is possible.

Do not delay emergency care to see whether severe symptoms settle on their own.

How Is the Cause of Stomach Pain Diagnosed?

A doctor will usually begin by asking when the pain started, where it is located, whether it moves to another area and what makes it better or worse. Other symptoms, medical history, medications and recent meals may also help guide the assessment.

Depending on the findings, the evaluation may include:

• Physical examination: To assess tenderness, swelling and other signs.

• Blood tests: To check for infection, inflammation or problems involving organs such as the liver or pancreas.

• Urine tests: To investigate urinary infections or possible kidney stones.

• Ultrasound: May help identify gallstones and certain abdominal or pelvic conditions.

• CT scan or other imaging: May be needed when the cause remains unclear or a serious condition is suspected.

When to Consult a Gastroenterologist in Trichy

Occasional mild stomach discomfort may settle, but pain that persists, repeatedly returns or interferes with daily activities should be evaluated. A medical consultation is especially important if you notice changes in bowel habits, unexplained weight loss, difficulty swallowing or ongoing digestive symptoms.

At Maruti Hospital, Tiruchirappalli, a consultation can help assess your symptoms and determine whether further investigations or treatment are needed. If your pain is sudden or severe, or you have any emergency warning signs, seek immediate medical care.
