Left vs. Right Side Stomach Pain: Causes, Symptoms and When to See a Doctor

Abdominal pain is one of the most common health complaints experienced by people of all ages. What often makes stomach pain confusing is that it can originate from several organs located close together, making it difficult to pinpoint the exact cause. Whether it appears suddenly or develops gradually, stomach pain can interfere with daily activities, sleep, and overall quality of life.

In this blog, we explain how pain on different sides of the abdomen can indicate various medical conditions.

Understanding Abdominal Pain and Its Location

Broadly, abdominal pain can be categorised based on duration and intensity. Acute pain usually develops suddenly and may indicate an infection, inflammation, or obstruction. Chronic pain, on the other hand, persists for weeks or months and is often linked to digestive disorders or long-standing medical conditions.

Some key reasons why pain location matters include:

  • Pain on the left side is commonly associated with digestive issues, gas-related discomfort, or problems involving the stomach or spleen.
  • Pain on the right side may indicate liver, gallbladder, or appendix-related conditions.
  • Central abdominal pain can suggest stomach ulcers or intestinal issues.

Because left-sided abdominal pain and pain on the right side can signal very different health concerns, ignoring persistent discomfort can delay diagnosis and treatment. If symptoms continue or worsen, consulting a specialist such as a gastroenterologist in Delhi NCR can help identify the exact cause and ensure the right care.

Reason for Stomach Pain on Left Side

The left side of the abdomen contains the stomach, part of the large intestine, pancreas, left kidney, and spleen. Any irritation, inflammation, or dysfunction in these organs can lead to left-sided abdominal pain. Since multiple organs are involved, doctors rely on symptom patterns, medical history, and diagnostic tests to determine the cause accurately.

Below are some of the common medical reasons associated with left-sided abdominal discomfort:

  • Gastritis or Acid Reflux: Excess stomach acid may irritate the stomach lining.
  • Constipation or Trapped Gas: It leads to bloating and cramp-like pain.
  • Irritable Bowel Syndrome: It can cause recurring abdominal discomfort along with bowel irregularities.
  • Kidney-Related Issues: Infections or stones, which may radiate pain to the lower abdomen.
  • Splenic Conditions: It includes enlargement or injury, which can cause pain under the left ribcage.

Consulting an experienced gastroenterologist in Faridabad can help diagnose the condition early and prevent further complications.

Left-Side Stomach Pain in Women

In women, left-sided stomach pain may be influenced by additional reproductive health factors along with digestive or urinary causes. Hormonal changes, menstrual cycles, and gynaecological conditions can sometimes make diagnosis more complex. Because symptoms may overlap, it is important to observe pain patterns, duration, and associated signs carefully.

Women should consider seeking medical attention if:

  • Pain is severe or sudden in onset
  • Symptoms worsen during menstrual cycles.
  • Pain is accompanied by abnormal bleeding.
  • There is persistent pain in the left side of the stomach despite medication.

Timely evaluation helps differentiate between digestive and gynaecological causes.

Right-Side Stomach Pain: Causes and Concerns

Right-sided stomach pain can arise from organs such as the liver, gallbladder, appendix, and part of the intestines. While some causes are mild, others may progress rapidly if left untreated. The nature of right-side abdomen pain can vary from dull and aching to sharp and severe. Associated symptoms such as nausea, fever, or vomiting often help in identifying the seriousness of the condition.

Some common causes include:

  • Gallbladder disorders, including gallstones or inflammation
  • Liver-related issues, such as infections or fatty liver disease
  • Appendicitis, which usually begins near the navel and shifts to the right lower abdomen
  • Intestinal infections or inflammation

Early consultation with a specialist, such as a gastroenterologist in Noida, allows timely diagnosis and prevents complications that may require emergency intervention.

When Right-Side Stomach Pain Could Be Serious

While some causes of right-sided abdominal discomfort are temporary, certain conditions linked to right-side abdomen pain require immediate medical attention.

Some warning situations where right-side stomach pain should be considered serious include:

  • Appendicitis: The pain increases rapidly and is often accompanied by fever, nausea, or vomiting.
  • Gallbladder Inflammation: It may cause sharp pain after eating fatty foods.
  • Liver Infections or Inflammation: It leads to persistent discomfort and fatigue.
  • Intestinal Obstruction: It can result in severe pain, bloating, and inability to defecate.

If the pain becomes intense, localised, or progressively worse, it is important to seek immediate evaluation.

Symptoms That Should Not Be Ignored

Abdominal pain often presents with additional symptoms that provide important diagnostic clues. Paying attention to these signs can help determine whether medical intervention is required.

Some symptoms that indicate the need for prompt medical consultation include:

  • Persistent pain lasting more than a few days
  • Fever, nausea, or repeated vomiting
  • Unexplained weight loss or loss of appetite
  • Blood in stools or dark-coloured stools
  • Severe pain in the left side of the stomach or sudden right-side stomach pain

Ignoring these symptoms may allow an underlying condition to worsen. Consulting a specialist, such as a gastroenterologist in Delhi NCR, ensures a thorough evaluation and timely management.
