Medically Reviewed by - Dr Dhiraj Gopal Agrawal

Abdominal pain is one of the most common reasons people visit a doctor. When the pain is felt on the left side, it can create worry and confusion. Is it gas? Is it a stomach infection? Or could it be something more serious?

Left side abdominal pain can happen for many reasons. Some causes are mild and temporary. Others may need urgent medical attention. Understanding the possible abdominal pain causes can help you know when to wait and when to seek care.

Understanding the Left Side of the Abdomen

The left side of the abdomen contains several important organs, including:

  • Stomach
  • Small intestine
  • Large intestine
  • Pancreas
  • Spleen
  • Left kidney
  • In women, the left ovary and fallopian tube

Because many organs are located here, pain in left side of the abdomen can come from different systems such as digestive, urinary, or reproductive.

Common Causes of Abdominal Pain on the Left Side

1. Gas and Bloating
One of the most common abdominal pain causes is gas buildup. Trapped gas in the intestine can lead to sharp or cramping stomach pain left side. This type of abdominal pain often improves after passing gas or having a bowel movement.

Symptoms may include:

  • Bloating
  • Feeling full
  • Mild cramps
  • Burping

This type of abdominal pain left side is usually not serious.

2. Constipation
Constipation can cause pressure in the colon, leading to left side abdominal pain. When stool builds up, it stretches the intestine and causes discomfort.

Symptoms:

  • Hard stools
  • Infrequent bowel movements
  • Straining
  • Feeling of incomplete emptying

Dietary changes and hydration often help relieve this type of abdominal pain.

3. Diverticulitis
Diverticulitis is a common reason for abdominal pain left side, especially in adults above middle age. Small pouches called diverticula can form in the colon. When these become inflamed or infected, they cause significant abdominal pain.

Symptoms include:

  • Constant pain on left side of stomach
  • Fever
  • Nausea
  • Changes in bowel habits

This condition requires medical treatment. If untreated, it may lead to complications.

4. Gastritis and Stomach Ulcers
Inflammation of the stomach lining can cause stomach pain left side, particularly in the upper abdomen. Gastritis may develop due to infection, long term use of certain medications, or stress.

Ulcers can also cause burning abdominal pain after eating.

Common symptoms:

  • Burning sensation
  • Nausea
  • Indigestion
  • Abdominal pain after eating

If pain persists, medical evaluation is necessary.

5. Pancreatitis
The pancreas lies behind the stomach. Inflammation of the pancreas can cause severe abdominal pain left side that may spread to the back.

Symptoms:

  • Severe upper abdominal pain
  • Vomiting
  • Fever
  • Worsening pain after meals

Pancreatitis requires urgent medical care.

6. Kidney Stones
Kidney stones on the left side can cause intense pain in left side that starts from the back and moves toward the lower abdomen.

Symptoms:

  • Sharp, severe pain
  • Blood in urine
  • Frequent urination
  • Nausea

This type of abdominal pain can be very sudden and severe.

7. Irritable Bowel Syndrome
Irritable bowel syndrome can cause recurring abdominal pain left side. The pain is often associated with changes in bowel habits.

Symptoms:

  • Cramping
  • Diarrhea or constipation
  • Bloating
  • Relief after bowel movement

IBS is a long term condition but can be managed with lifestyle and dietary changes.

8. Ovarian Conditions in Women
In women, pain in left side of abdomen may be due to ovarian cysts, infection, or other gynecological conditions.

Symptoms may include:

  • Pelvic pain
  • Irregular periods
  • Pain during movement
  • Abdominal pain after eating in some cases

Women experiencing persistent left side abdominal pain should consult a specialist.
