What Causes Pain In The Left Stomach?


Pain in the lower left stomach can be a concerning and uncomfortable experience for many individuals. This type of abdominal discomfort can range from mild to severe and may be accompanied by other symptoms such as bloating, nausea, or changes in bowel movements.

While pain in the left stomach can have various possible causes, it is essential to understand the potential underlying factors to seek appropriate medical attention when necessary.

In this article, we will explore the common reasons behind pain in the lower left stomach, discussing both benign and more serious conditions that may require further investigation and treatment. By familiarizing yourself with these potential causes, you can better advocate for your health and well-being.

causes Of pain in the left stomach

One of the most common causes of pain in the lower left stomach is gas and bloating. When excess gas accumulates in the digestive tract, it can lead to discomfort and a feeling of fullness or pressure in the abdominal area, sometimes extending to the area around the belly button.

What Causes Pain In The Left Stomach

This type of pain is often relieved by passing gas or having a bowel movement. Certain foods, such as beans, lentils, and dairy products, can increase gas production and contribute to this type of abdominal pain.

1. Constipation 

Another possible cause of pain in the left stomach is constipation. When stool becomes hard and difficult to pass, it can cause discomfort and cramping in the lower abdomen. Constipation can be caused by a lack of fiber in the diet, dehydration, or certain medications.

Increasing your intake of water and fiber-rich foods, such as fruits, vegetables, and whole grains, can help alleviate constipation and the associated abdominal pain.

2. Irritable bowel syndrome

Irritable Bowel Syndrome (IBS) is a chronic condition that can cause recurrent pain in the lower left stomach. IBS is characterized by abdominal discomfort, bloating, and changes in bowel habits, such as diarrhea or constipation.

The exact cause of IBS is not well understood, but factors such as stress, certain foods, and gut bacteria may play a role. Managing stress, identifying and avoiding trigger foods, and following a balanced diet can help manage IBS symptoms.

3. Diverticulitis 

Diverticulitis is another potential cause of pain in the left stomach, particularly in older adults. It occurs when small pouches (diverticula) that develop in the lining of the colon become inflamed or infected.

Diverticulitis is characterized by intense abdominal pain, elevated body temperature, and alterations in bowel patterns.m Treatment typically involves antibiotics, rest, and a temporary low-fiber diet. Surgery might be required in serious instances to eliminate the affected segment of the colon.

4. Inflammatory bowel disease 

Inflammatory Bowel Disease (IBD), which includes Crohn's disease and ulcerative colitis, can also cause pain in the lower left stomach. IBD is a chronic condition that causes inflammation in the digestive tract, leading to abdominal pain, diarrhea, and weight loss.

The exact cause of IBD is not known, but it is thought to involve a combination of genetic, environmental, and immune factors. Treatment for IBD often includes medications to reduce inflammation, such as corticosteroids or immunosuppressants, as well as dietary modifications.

5. Gynecological issues 

In some cases, pain in the lower left stomach may be related to gynecological issues in women. Conditions such as endometriosis, ovarian cysts, or pelvic inflammatory disease can cause abdominal discomfort and pain.

Endometriosis occurs when tissue similar to the lining of the uterus grows outside of the uterus, leading to pain and other symptoms. Ovarian cysts are fluid-filled sacs that develop on the ovaries and can cause abdominal pain if they become large or rupture.

Pelvic inflammatory disease is an infection of the reproductive organs that can cause lower abdominal pain and fever. If you suspect that your abdominal pain may be related to a gynecological issue, it is important to consult with a healthcare provider for proper diagnosis and treatment.

6. Other serious medical issues

In rare cases, pain in the left stomach may indicate a more serious condition, such as colon cancer or a bowel obstruction. Colon cancer typically develops from precancerous polyps in the colon and can cause abdominal pain, changes in bowel habits, and rectal bleeding. Regular colon cancer screening, such as colonoscopies, can help detect and remove precancerous polyps before they develop into cancer.

A bowel obstruction occurs when the intestines become blocked, preventing the normal passage of digested material. This can lead to severe abdominal pain, vomiting, and an inability to pass gas or stool. A bowel obstruction requires immediate medical attention and may require surgery to resolve.

It is important to note that musculoskeletal issues, such as a pulled muscle or a herniated disc in the lower back, can cause pain that is felt in the abdominal area.

Additionally, pain in the lower left stomach can also be referred to as pain from other areas of the body. For example, a kidney infection or kidney stones can cause pain that radiates to the lower left abdomen and may be felt near the belly button. If your pain is severe, persistent, or accompanied by other concerning symptoms, such as fever, vomiting, or bloody stools, it is essential to seek medical attention promptly.


Pain in the lower left stomach can have various possible causes, ranging from benign conditions like gas and bloating to more serious issues such as diverticulitis or colon cancer. Understanding the potential underlying factors can help you better manage your symptoms and know when to seek medical attention.

By making lifestyle changes, such as increasing your fiber and water intake, managing stress, and avoiding trigger foods, you may be able to alleviate mild abdominal discomfort. 

However, if your pain is severe, persistent, or accompanied by other concerning symptoms, it is crucial to consult with a healthcare provider for proper diagnosis and treatment. Always prioritize your health and well-being. If you experience recurring or severe pain in your lower left stomach, don't hesitate to advocate for yourself and seek the medical care you need.
