Stomach pain can occur on either the left side or right side of the abdomen, with causes ranging from mild digestive issues to serious medical conditions. Left side abdominal pain may indicate problems like gas, constipation, or kidney stones, while pain on the right side of the stomach could signal appendicitis, gallbladder disease, or liver conditions. If you experience persistent or severe pain, seek medical attention.

Understanding Stomach Pain by Location

Abdominal pain is a common symptom that can arise from various conditions affecting the digestive system, kidneys, liver, or other organs. The location of the pain often provides valuable clues about its cause. While occasional discomfort may be harmless, persistent or sharp pain can indicate underlying stomach problems that require medical evaluation.

Left Side Abdominal Pain: Causes & Symptoms

Pain on the left side of the abdomen can be caused by issues in the stomach, intestines, kidneys, or reproductive organs.

1. Gas and Indigestion

Trapped gas can cause cramping or sharp pain in the left abdominal region, especially after eating certain foods. Bloating, belching, and discomfort that improves after passing gas are common signs.

2. Constipation

A lack of fibre or dehydration can lead to hard stools, causing pain in the lower left abdomen. Symptoms include infrequent bowel movements and bloating.

3. Diverticulitis

Inflammation of small pouches in the colon (diverticula) can cause persistent pain in the lower left abdomen, along with fever, nausea, and changes in bowel habits.

4. Kidney Stones

Small, hard deposits in the kidneys can cause sharp left side abdominal pain that radiates to the back and groin. Other symptoms include blood in the urine and frequent urination.

5. Ovarian Cysts (in Women)

Fluid-filled sacs on the ovaries can cause left lower abdominal pain, irregular periods, and bloating. Severe cases may require medical intervention.

6. Spleen Issues

An enlarged or ruptured spleen due to infections or injury can cause pain in the upper left abdomen, along with fatigue and easy bruising.

Right Side Abdominal Pain: Causes & Symptoms

Pain on the right side of the stomach often indicates issues with the liver, gallbladder, appendix, or intestines.

1. Appendicitis

Pain in the lower right abdomen is a hallmark symptom of appendicitis. The pain usually starts around the belly button and shifts to the right lower side, accompanied by nausea, fever, and loss of appetite.

2. Gallbladder Disease

Gallstones or inflammation of the gallbladder can cause pain in the upper right abdomen, particularly after eating fatty meals. Symptoms may include nausea, vomiting, and jaundice.

3. Liver Problems

Conditions like hepatitis or fatty liver disease can cause dull pain on the right side of the stomach, along with fatigue, yellowing of the skin (jaundice), and nausea.

4. Kidney Infections or Stones

Similar to the left side, kidney infections or stones can cause right-side abdominal pain, back pain, fever, and painful urination.

5. Irritable Bowel Syndrome (IBS)

Chronic digestive issues can lead to pain on either side of the stomach, bloating, and altered bowel movements.

6. Ovarian Cysts (in Women)

Cysts on the right ovary can cause pain in the lower right abdomen, irregular menstrual cycles, and bloating.

Stomach Pain After Eating: Possible Causes

If your stomach pain occurs after eating, it could be linked to digestion-related problems.

1. Acid Reflux (GERD)

Acid backing up into the oesophagus can cause burning pain in the upper abdomen after meals.

2. Gastritis

Inflammation of the stomach lining, often due to infection or excessive alcohol consumption, can cause upper abdominal pain, nausea, and bloating.

3. Food Intolerances

Lactose or gluten intolerance can lead to bloating, diarrhoea, and stomach pain after eating certain foods.

4. Gallbladder Disease

Pain in the upper right abdomen after fatty meals may indicate gallstones or gallbladder inflammation.

Chronic Abdominal Pain: When Pain Persists

Chronic abdominal pain refers to discomfort that lasts for weeks or months. It may be caused by conditions like:

  • Irritable Bowel Syndrome (IBS) – Alternating constipation and diarrhoea with bloating.
  • Inflammatory Bowel Disease (IBD) – Includes Crohn’s disease and ulcerative colitis, which cause persistent abdominal pain.
  • Endometriosis (in Women) – Tissue similar to the uterine lining grows outside the uterus, leading to chronic pelvic pain.

If you experience chronic abdominal pain, seek medical evaluation to determine the underlying cause.

Treatment for Left or Right Side Abdominal Pain

The treatment for abdominal pain depends on its cause.

1. Lifestyle and Dietary Changes

  • Drinking plenty of water and eating a fibre-rich diet can relieve constipation.
  • Avoiding trigger foods like spicy, fatty, or dairy-heavy meals can prevent stomach pain after eating.

2. Medications

  • Antacids or proton pump inhibitors (PPIs) for acid reflux.
  • Pain relievers for kidney stones or menstrual cramps.
  • Antibiotics for bacterial infections like appendicitis or kidney infections.

3. Surgery

  • Appendectomy for appendicitis.
  • Gallbladder removal for severe gallstones.
  • Kidney stone removal if the stones are too large to pass naturally.

When to See a Doctor?

Seek medical attention if you experience:

  • Severe or worsening pain that does not improve.
  • Persistent pain in the lower right abdomen could indicate appendicitis.
  • Pain in the upper right abdomen with nausea or jaundice, possibly due to gallbladder or liver disease.
  • Fever, vomiting, or blood in stools, may signal a serious condition.
