Upper Left Abdominal Pain

Many people notice pain in the upper left side of their abdomen and wonder why it happens. Digestive issues like indigestion, constipation, gastritis, and pancreatitis often cause upper left abdominal pain, but problems with the spleen, heart, or ribs can also be responsible.

Sometimes, muscle strain causes the pain, but it can also signal a more serious condition. Knowing the possible reasons for this type of pain helps people decide if they need to see a doctor or if the problem might go away on its own.

Definition of Symptom

Upper left abdominal pain is discomfort or aching that occurs on the left side of the abdomen, just below the ribs. This area is sometimes called the left upper quadrant (LUQ). The pain can range from mild to severe and may be sharp, dull, or cramping.

Common Features of Upper Left Abdominal Pain

  • Location: Upper left side, below the rib cage.
  • Quality: Sharp, aching, stabbing, or burning.
  • Duration: Short-lived or constant.

Sometimes, upper left abdominal pain is felt directly under the ribs. This pain can spread to the back or shoulder and might get worse with movement or deep breathing. The upper left abdomen contains several organs, including:

OrganFunction
StomachDigests food
SpleenFilters blood
Pancreas (part)Produces insulin/enzymes
Left kidney (top)Filters blood, forms urine
Left lung (lower)Helps with breathing

Problems with any of these organs, or with nearby muscles and bones, can cause pain in this area. Symptoms that can come with upper left abdominal pain include:

  • Nausea
  • Vomiting
  • Tenderness when touched
  • Trouble breathing
  • Bloating

Possible Causes/Diseases Condition

Many different issues can cause pain in the upper left abdomen. Some are related to digestion, while others involve organs like the spleen and kidneys. Digestive conditions are the most common source. These include gastritis (stomach lining irritation), ulcers, or irritable bowel syndrome (IBS), which can lead to cramping, bloating, and pain.

Ulcerative colitis is a long-term condition that causes swelling and sores in the large intestine, sometimes leading to pain in the upper left area. The spleen sits beneath the left ribs. When it becomes enlarged, often due to infections or blood disorders, it may cause pain or a feeling of fullness. Problems with the pancreas like pancreatitis (swelling) can cause severe, constant pain in the upper left abdomen.

Alcohol use or gallstones often lead to pancreatitis. Kidney conditions may also lead to pain. Kidney stones or a kidney infection often cause pain on one side, which may spread to the back, and may come with fever or urinary problems. Rarely, conditions such as pericarditis (swelling of the sac around the heart) can cause pain in the upper abdomen that may be confused with other causes.

Table: Potential Causes

CauseTypical Symptoms
Gastritis/UlcersBurning pain, nausea, bloating
Irritable Bowel SyndromeCramping, bloating, variable pain
Ulcerative ColitisBloody stools, chronic pain
Enlarged SpleenFullness, tenderness under ribs
PancreatitisSevere pain, nausea, vomiting
Kidney Stones/InfectionSharp pain, urinary problems
PericarditisChest/upper abdominal pain, fever

Other Non-Disease Causes

Some causes of pain in the upper left abdomen are not related to disease. Instead, they are linked to everyday activities or simple physical issues.

Muscle Strain

  • Lifting heavy objects
  • Intense exercise
  • Sudden movements

Straining the muscles between the ribs or in the abdomen can lead to sharp or dull pain. The pain often gets worse with movement or deep breaths.

Digestive Issues
Occasional pain may come from gas or bloating after eating. Eating too quickly, drinking carbonated beverages, or swallowing air can lead to mild discomfort.

CausePossible Trigger
Gas/BloatingCarbonated soda, overeating
ConstipationLow fiber intake, dehydration

Injury or Trauma

A minor bump or blow to the upper left abdomen can result in bruising or soreness. The pain can last for several days as the area heals.

Posture

Poor sitting or standing posture can put extra pressure on abdominal muscles. Over time, this can cause discomfort on the left side.

How It Causes the Symptom

If an organ gets irritated, swollen, or injured, it sends pain signals. For example, an enlarged spleen stretches the tissue, which triggers discomfort or sharp pain under the ribs. Common reasons for upper left abdominal pain include:

  • Indigestion or Gastritis: Stomach lining irritation causes burning pain.
  • Kidney Problems: Infections or stones irritate the kidney, leading to sharp or aching pain that sometimes spreads to the back.
  • Pancreatitis: Swelling makes the pancreas sore, causing persistent pain that may worsen after eating.

Infections or swelling can also make the area feel tender. For example, a lung infection on the left side can make the upper abdomen sore. If a problem causes internal bleeding, like a ruptured spleen, blood can build up and press on nearby tissues. This creates sudden and severe pain.

OrganPossible CauseHow It Triggers Pain
StomachGastritis, ulcersIrritation of stomach lining
SpleenEnlargement, ruptureTissue stretching or bleeding
KidneyInfection, stonesSwelling or blockage
PancreasInflammation (pancreatitis)Pressure or irritation

Other symptoms, like nausea, fever, or trouble breathing, may appear depending on the affected organ.

Possible Complications

Ignoring upper left abdominal pain can lead to serious problems with the organs in that area. If the spleen is involved, it can rupture and cause severe internal bleeding. Problems with the pancreas, like pancreatitis, can result in infection, tissue damage, or trouble with blood sugar control. Severe cases may need hospital care.

If the pain is related to the stomach or colon, possible complications include ulcers, bleeding, or blocked bowels. These may need urgent treatment to prevent lasting harm. Kidney issues, such as infections or stones, can cause kidney damage if not treated. Infections may spread to the bloodstream, leading to sepsis. A quick overview of possible complications:

CausePossible Complications
Spleen injuryRupture, internal bleeding
PancreatitisInfection, tissue death
Stomach/colon issuesUlcers, bleeding, blockage
Kidney diseaseDamage, infection, sepsis

Some underlying causes, like infections or swelling, can become more serious if ignored. Anyone with ongoing or severe upper left abdominal pain should consult a healthcare provider to avoid these complications.

When to Seek Medical Attention

Watch for warning signs that could mean a serious problem. Do not ignore severe or sudden pain in the upper left abdomen. Get medical help right away if you experience:

  • Severe or constant pain
  • Pain with chest discomfort, sweating, or shortness of breath
  • Fever or chills
  • Dizziness or fainting
  • Vomiting blood or finding blood in stool
  • Yellowing of the skin or eyes

If pain keeps coming back or gets worse, see a doctor. A healthcare provider can check for the cause. If you are unsure, it is safer to get care than to wait.
