Pain in the Upper Left Abdomen Symptoms

Since the upper left abdomen contains many important structures — either partially or entirely — it is important to examine the cause of your pain. If the pain is mild or resolves on its own, there is likely less cause for concern. However, it may be helpful in understanding persistent or recurrent pain in this area if we first look at the structures within it. The upper left part of the abdomen contains several structures including:

  • Pancreas
  • Spleen
  • Stomach
  • Diaphragm
  • Left lower rib cage
  • Left lower lung
  • Left lobe of the liver
  • Left kidney
  • Left adrenal gland
  • Upper left sections of the large intestine

Pain in the upper left abdomen is also called pain in the left upper quadrant, pain under the left rib cage, or pain in the left hypochondrium.


The pain and tenderness you may experience can likely be described by the following details:

  • Location: It will likely be beneath the lower edge of the rib cage, on the left side.
  • Sensitive: The pain will be evident on palpation (pressing) of the left upper abdomen.
  • Varied: The pain may range from mild and dullto severe and sharp.
  • Mobile: The pain may travel into the back at the same level, or to the left shoulder.
  • Worse when lying down

Other symptoms

You may also have a general ill feeling, as well as the following:


Pain from any of the left upper quadrant structures can be acute (brief) or chronic (continuing for a long time).

Who is most often affected?

People who are most likely to experience pain in the upper left abdomen include:

  • Men
  • Drinkers, since five or more alcoholic drinks per day can damage the pancreas
  • Anyone with high triglyceride levels
  • Anyone taking large amounts of prescription medication
  • Anyone using illicit drugs

When is it most likely to occur?

Pain may get worse after eating a large meal, especially one with high-fat foods.

Is pain in the upper left abdomen serious?

Pain can vary in severity depending on the cause.

  • Moderately serious: Ongoing left-sided pain that does not clear up quickly with rest, or that has symptoms that continue to get worse is considered moderately serious.
  • Serious: Left-sided pain accompanied by shortness of breath, pain in the jaw or arm, or with lightheadedness or fainting is considered serious.

Pain in the Upper Left Abdomen Causes Overview

Many conditions can cause the symptom of pain in the upper left abdomen. We've listed several different causes here, in approximate order from most to least common.

Systemic infections

Several different types of systemic, or body-wide infections, can affect the upper left abdomen, such as those that are:

  • Viral
  • Bacterial
  • Parasitic
  • Fungal

Localized infections

A localized infection, confined to one of the organs of the left upper quadrant can also occur.

  • Inflammation: This is likely in the pancreas with pancreatitis [1].
  • Infection: This is likely in the lung (pneumonia) or in the sac enclosing the heart (pericarditis)..
  • Abscess (a pocket of infection): These are likely in the kidney.
  • Ulcer: This is an erosion in the stomach or duodenum.


Injury to the abdomen can lead to pain that spreads, causing further damage due to internal bleeding, or is localized to one area. Causes may include accidents, sports injuries, or medical procedures such as surgeries, biopsies, or endoscopic procedures for examining the pancreas and other organs. Specific injuries that may occur include:

  • Lower left rib fracture: The broken rib can puncture the lung, spleen, or kidney.
  • Collapsed lower left lung: A collapsed lung can cause significant pain.
  • Ruptured organ: The spleen is especially vulnerable. This is a medical emergency due to the internal bleeding that may continue.

Idiopathic conditions

These are caused by a combination of diet and exercise choices, along with heredity, allergies, and sometimes viral infections.

  • Autoimmune diseases: These attack the organs of the left upper quadrant, causing damage and pain, such as lupus [2].
  • Metabolic disorders: These cause imbalances in the way the organs work, such as diabetes [3].
  • Left kidney: Mineral deposits ("stones") can cause severe pain.
  • Liver: Damage to the liver can cause enlargement of the spleen.
  • Stomach: Stomach acids can back up into the esophagus in diseases such as in gastroesophageal reflux disease (GERD).
  • Colon: Pain may come from the part of the colon lying under the left rib cage, caused by constipation or excess gas.

Drugs and medications

Many drugs can cause left upper quadrant pain and associated damage with chronic use [4]. A few are listed here:

  • Aspirin: High doses can cause stomach bleeding and pain [5].
  • NSAIDs: These are non-steroidal anti-inflammatory drugs, such as ibuprofen.
  • Oral antibiotics
  • Opioids: Pain may be due to the side effect of chronic constipation.
  • Chemotherapy drugs
  • Cocaine


Cancer is considered a rare cause of pain in the upper left abdomen.

  • Localized tumor: A cancerous growth anywhere in the left upper quadrant can cause pain. There may or may not be a lump in the vicinity of the pain.
  • Blood cancers: These will affect the entire body and cause symptoms in the organs of the left upper quadrant.

We've listed some specific conditions that can cause pain in the upper left abdomen, along with how to identify each of them.

A.I. Health Assistant Causes for Pain in the Upper Left Abdomen

The list below shows results from the use of our A.I. Health Assistant by Buoy users who experienced pain in the upper left abdomen. This list does not constitute medical advice.

  1. 1.Stomach Ulcer

    A peptic ulcer is a sore in the lining of the stomach or the first part of your small intestine (the duodenum), which causes pain following meals or on an empty stomach.

    2-4 weeks with treatment

    Top Symptoms:
    fatigue, nausea, loss of appetite, moderate abdominal pain, abdominal cramps (stomach cramps)
    Symptoms that never occur with stomach ulcer:
    pain in the lower left abdomen
    Primary care doctor
  2. 2.Indigestion (Dyspepsia)

    Indigestion, also known as dyspepsia, is a condition that causes pain or discomfort in the stomach after eating. In some cases, indigestion also causes heartburn, burping, and nausea. Indigestion or dyspepsia is a very common complaint. Every year, about 1 in every 4 people will experience an episode of dyspepsia, of which most cases do not have a serious underlying cause.

    These symptoms are likely to resolve, if they persist you should discuss this with your primary care physician.

    Top Symptoms:
    nausea, stomach bloating, dyspeptic symptoms, bloating after meals, vomiting
    Symptoms that always occur with indigestion (dyspepsia):
    dyspeptic symptoms
    Symptoms that never occur with indigestion (dyspepsia):
    vomiting (old) blood or passing tarry stools, rectal bleeding, bloody diarrhea, fever
  3. 3.Acute Gastritis

    Acute gastritis is the sudden onset of nausea, vomiting, and/or upper abdominal pain that's caused by inflammation of your stomach lining. If it doesn't go away, this can become an ulcer. Causes include taking a medication that affects the stomach, an infection by a bug called, "H. Pylori", or your immune system reacting to yourself.

    Prognosis is great with the appropriate treatment

    Top Symptoms:
    nausea or vomiting, nausea, stomach bloating, loss of appetite, mild abdominal pain
    Symptoms that never occur with acute gastritis:
    Primary care doctor
  4. 4.Acute Pancreatitis

    Acute pancreatitis is the inflammation of the pancreas, which creates and releases insulin and glucagon to keep the sugar levels in your blood stable. It also creates the enzymes that digest your food in the small intestine. When these enzymes accidentally get activated in the pancreas, they digest the pancreas itself, causing pain and inflammation.

    Acute pancreatitis typically goes away after a few days with treatment. Untreated, it can be deadly

    Top Symptoms:
    constant abdominal pain, nausea or vomiting, being severely ill, severe abdominal pain, fever
    Symptoms that always occur with acute pancreatitis:
    constant abdominal pain
    Hospital emergency room

  5. 5.Chronic Pancreatitis

    Chronic pancreatitis is a syndrome involving progressive inflammatory changes in the pancreas. This causes permanent structural damage, which can lead to symptoms including abdominal pain, nausea, and diarrhea.

    This is likely a lifelong condition.

    Top Symptoms:
    fatigue, abdominal pain (stomach ache), nausea or vomiting, loss of appetite, abdominal pain that comes and goes
    Primary care doctor
  6. 6.Normal Abdominal Pain

    The abdomen extends from below the chest to the groin. Often it is referred to as the stomach; however, the abdomen includes more organs than just the stomach like the pancreas & liver. Abdominal pain is not stomach-specific and may be radiating from another organ.

    Generally abdominal pain resolves within a few days.

    Top Symptoms:
    abdominal pain (stomach ache), vaginal discharge, fever, nausea
    Symptoms that always occur with normal abdominal pain:
    abdominal pain (stomach ache)
    Symptoms that never occur with normal abdominal pain:
    fever, vomiting, diarrhea, nausea, severe abdominal pain, unintentional weight loss, vaginal discharge, rectal bleeding
  7. 7.Kidney Stone

    A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.

    The prognosis for a kidney stone is good, as it is not a chronic condition. Once the stone has passed, the pain will go away. However, if you have had a kidney stone, you have about a 1 in 2 chance of getting another one in five to seven years. This can be prevented by: 1. Drinking more than 2 liters (2.11 quarts) of water a day. 2. Eating a healthy diet with foods rich in calcium such as milk and other dairy products, peas and beans, leafy green vegetables, nuts, and bony fish like sardines and salmon. 3. Avoiding use of lots of salt in cooking. 4. Eating more vegetables, as they help make urine less acidic.

    Top Symptoms:
    abdominal or flank pain, nausea, abdominal pain that comes and goes, diarrhea, pelvis pain
    Symptoms that always occur with kidney stone:
    abdominal or flank pain
    Hospital emergency room
  8. 8.Heart Attack in a Woman

    Most heart attacks happen when a clot in the coronary artery blocks the supply of blood and oxygen to the heart. Often this leads to an irregular heartbeat - called an arrhythmia - that causes a severe decrease in the pumping function of the heart.


    Top Symptoms:
    abdominal pain (stomach ache), nausea, pain in one arm, chest pain, shortness of breath

FAQs About Pain in the Upper Left Abdomen

Here are some frequently asked questions about pain in the upper left abdomen.

Does diabetes cause pain in the upper left abdomen?

The pancreas is located in the left upper quadrant, and a possible cause of diabetes is pancreatitis — an inflammation of the pancreas [1,3]. This causes pain and in some cases loss of ability to produce insulin, which leads to diabetes. Generally, very severe or long standing pancreatitis causes diabetes.

Is pain in the upper left abdomen connected to, or a warning of, a heart attack?

The heart is technically located in the chest, not the upper abdomen, but it can be hard to tell the difference if a heart attack is occurring. With a heart attack, there will be other symptoms such as pain in the arm, jaw, or neck, along with a cold sweat, shortness of breath, or nausea and vomiting [6].

Is pain in the upper left abdomen connected to, or a warning of, an aortic aneurysm?

An aortic aneurysm is a bulging in the wall of the aorta, which is the largest artery in the body and runs straight down from the heart. There may be pain almost anywhere in the back and/or abdomen, though it will most often be felt lower in the back at about the level of the navel [7,8].

Is pain in the upper left abdomen a sign of an abnormal pregnancy?

An ectopic pregnancy — one in which the fetus is growing inside a fallopian tube instead of inside the uterus — first causes internal bleeding. This irritates the nerves and causes pain into the upper abdomen and shoulders. There will also be signs of very early pregnancy and sudden, severe pain if the tube begins to rupture (a life-threatening medical emergency).

Is pain in the upper left abdomen part of a normal pregnancy?

A normal pregnancy can cause some conditions that lead to pain in the upper left abdomen. Constipation is a common one, as is heartburn (acid reflux from the stomach into the lower esophagus) [9]. However, a complication of pregnancy called pre-eclampsia can cause general upper abdominal pain and high blood pressure and is considered a medical emergency [10].
