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.

Upper left abdomen anatomy

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.

Common characteristics of pain in the upper left abdomen

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.

Pain In The Upper Left Abdomen Causes

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.

8 Possible Pain In The Upper Left Abdomen Conditions

The list below shows results from the use of our quiz by Buoy users who experienced pain in the upper left abdomen. This list does not constitute medical advice and may not accurately represent what you have.

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.

Rarity: Uncommon

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

Urgency: Primary care doctor

Indigestion (dyspepsia)

Indigestion, also called upset stomach, dyspepsia, or functional dyspepsia, is not a disease but a collection of very common symptoms. Note: Heartburn is a separate condition.

Common causes are eating too much or too rapidly; greasy or spicy foods; overdoing caffeine, alcohol, or carbonated beverages; smoking; and anxiety. Some antibiotics, pain relievers, and vitamin/mineral supplements can cause indigestion.

The most common symptoms are pain, discomfort, and bloating in the upper abdomen soon after eating.

Indigestion that lasts longer than two weeks, and does not respond to simple treatment, may indicate a more serious condition. Upper abdominal pain that radiates to the jaw, neck, or arm is a medical emergency.

Diagnosis is made through patient history and physical examination. If the symptoms began suddenly, laboratory tests on blood, breath, and stool may be ordered. Upper endoscopy or abdominal x-ray may be done.

For functional dyspepsia – "ordinary" indigestion – treatment and prevention are the same. Eating five or six smaller meals per day with lighter, simpler food; managing stress; and finding alternatives for some medications will provide relief.

Rarity: Common

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

Urgency: Self-treatment

Acute gastritis

When something interferes with the protective mechanisms of the stomach, a range of problems can occur from mild indigestion to deadly bleeding ulcers. Gastritis is an umbrella term for one of the most common problems, inflammation of the stomach lining.

Symptoms include nausea or vomiting,...

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.

Rarity: Rare

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

Urgency: Hospital emergency room

Chronic pancreatitis

Chronic pancreatitis is an inflammation of the pancreas that does not improve, but slowly gets worse over time.

Causes include alcoholism; a blocked pancreatic duct; autoimmune disease, where the body's natural defenses turn against itself; and possible genetic factors.

Chronic pancreatitis is most common in men from age 30 to 40 with a history of alcoholism and a family history of the disease, but anyone can be affected.

Symptoms include severe pain in the back and abdomen, especially with eating; weight loss; nausea and vomiting; and diarrhea with oily-appearing, pale-colored stools.

The pancreas is vital for blood sugar control and for secreting certain digestive enzymes. If not treated, chronic pancreatitis can lead to permanent pancreatic damage, diabetes, malnutrition, and chronic pain.

Diagnosis is made through patient history, physical examination, and imaging such as x-ray, CT scan, or ultrasound.

Treatment involves pain management through both medication and surgical procedures. Lifestyle improvements through diet, exercise, and stress management can also be very helpful.

Rarity: Rare

Top Symptoms: fatigue, abdominal pain (stomach ache), nausea or vomiting, loss of appetite, abdominal pain that comes and goes

Urgency: Primary care doctor

Normal abdominal pain

The complaint of nonspecific abdominal pain and discomfort, with no apparent cause, is one of the most common in medicine. It is a primary reason for patients to visit a medical provider or the emergency room.

The cause of abdominal pain can be difficult to find, because it can come from many different sources: the digestive tract, the urinary tract, the pancreas, the gall bladder, or the gynecologic organs.

The pain may simply be caused by overly sensitive nerves in the gut. This hypersensitivity can occur after repeated abdominal injury and/or it may have an emotional cause due to fear of the pain itself.

Diagnosis is made through physical examination, patient history, and simply ruling out any other condition. CT scan is often requested, but can rarely find a specific cause. The benefits must be weighed against the risks of radiation.

Treatment first involves making any needed lifestyle improvements regarding diet, exercise, work, and sleep, in order to reduce stress. In some cases, counseling, hypnosis, mild pain relievers, and antidepressants are helpful.

Rarity: Common

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

Urgency: Self-treatment
