That dull ache or sharp twinge on the right side of your abdomen – it’s hard to ignore, and it’s easy to worry. Whether it comes on after a meal, during pregnancy, or seemingly out of nowhere, pain in the right side of the stomach is one of the most common complaints people bring to a clinic. Sometimes it passes quickly. Other times, it’s your body trying to tell you something important.
This guide breaks down the most likely stomach pain reasons, explains when a stomach pain tablet is enough, and helps you understand when it’s time to see a doctor.
Why Does the Right Side of the Stomach Hurt?
The right side of your abdomen is home to several important organs – the liver, gallbladder, right kidney, part of the large intestine, and in women, the right ovary. Pain in this area can originate from any one of these structures, which is why pinpointing the exact cause matters.
Here are the most common stomach pain reasons specific to the right side:
- Appendicitis – Sharp pain that begins around the navel and moves to the lower right side. This is a medical emergency.
- Gallstones – Pain in the upper right abdomen, often after fatty meals, sometimes radiating to the shoulder.
- Kidney Stones or Infection – Right-sided pain that may extend to the back or groin, often with urinary changes.
- Liver Issues – Dull, persistent upper right stomach pain that may be linked to liver inflammation or fatty liver disease.
- Gas and Bloating – Stomach pain gas is one of the most common and benign causes of right-sided discomfort.
- Irritable Bowel Syndrome (IBS) – Cramping that shifts around the abdomen, often related to diet and stress.
- Muscle Strain – If you’ve recently exercised or lifted something heavy, the pain may simply be muscular.
Understanding Pain in Lower Right Side of Stomach
Pain in the lower right side of the stomach deserves special attention. While trapped gas or a pulled muscle is often the culprit, this is also the exact location of the appendix. Appendicitis pain typically starts mild and worsens over several hours – and it won’t resolve on its own.
Seek immediate medical attention if lower right stomach pain is accompanied by:
- Fever above 38°C (100.4°F)
- Nausea and vomiting
- Pain that worsens when you release pressure (rebound tenderness)
- Inability to stand up straight
Upper Stomach Pain: Could It Be Your Gallbladder or Liver?
Upper stomach pain on the right side is most commonly associated with the gallbladder. Gallbladder attacks often occur after eating greasy or fatty food and can feel like a tight, squeezing pressure under the ribcage.
Liver-related discomfort tends to be more gradual – a heaviness or fullness rather than sharp pain. Conditions like non-alcoholic fatty liver disease (NAFLD) are increasingly common and may not cause any symptoms at all in the early stages.

Stomach Pain After Eating: What’s Going On?
Stomach pain after eating can be alarming, but it’s often a sign of a digestive issue rather than something more serious. Here are the most frequent reasons for lower stomach pain and upper discomfort that appear after meals:
Acid Reflux and GERD
A burning sensation in the upper stomach or chest after eating is a hallmark of acid reflux. Spicy foods, caffeine, and large meals are common triggers.
Food Intolerances
Lactose intolerance, gluten sensitivity, or food allergies can cause bloating, cramps, and pain in the right side of the stomach within 30–60 minutes of eating.
Stomach Pain Gas
Gas is one of the most underestimated causes of abdominal pain. It can build up on either side and cause significant discomfort. Eating too fast, carbonated drinks, and high-fibre foods are common triggers.
Stomach Pain in Pregnancy: What’s Normal and What’s Not
Stomach pain in pregnancy is common, but it’s important to distinguish between normal discomfort and warning signs.
Generally expected discomfort includes:
- Round ligament pain (sharp or stabbing pain on the lower right during the second trimester)
- Braxton Hicks contractions (irregular tightening of the uterus)
- Gas and bloating due to hormonal changes
Seek medical attention immediately during pregnancy if you have:
- Severe or persistent pain in the lower right side of the stomach
- Vaginal bleeding or unusual discharge
- Fever, chills, or painful urination
- Sudden swelling of the hands or face with headache

Stomach Pain Relief: What Helps at Home
For mild, non-emergency stomach pain, these evidence-based home strategies can offer stomach pain relief while you monitor your symptoms:
Warm Compress
Applying a warm water bottle or heating pad to the abdomen can relax tense muscles and ease cramping or gas-related pain.
Hydration and Rest
Dehydration can worsen digestive discomfort. Sipping plain water or a dilute electrolyte drink can help, especially if you’ve had diarrhoea or vomiting.
Dietary Adjustments
- Avoid spicy, fatty, or heavily processed food until the pain settles
- Eat smaller, more frequent meals
- Reduce carbonated beverages and alcohol
Choosing the Right Stomach Pain Tablet or Medicine
Over-the-counter options can help with mild symptoms, but the right stomach pain medicine depends on the underlying cause. Here’s a general overview:
- Antacids (e.g., Gelusil, Digene) — Best for acid reflux and heartburn-related upper stomach pain.
- Antispasmodics (e.g., Meftal Spas) — Help with cramps and spasms, often used for IBS or menstrual pain.
- Simethicone-based tablets — Effective for stomach pain gas and bloating.
- Oral Rehydration Salts (ORS) — Essential if vomiting or diarrhoea accompanies the pain.
Important: Never take a painkiller for undiagnosed stomach pain – it can mask symptoms of serious conditions like appendicitis and delay critical treatment.

When Should You See a Doctor?
Most stomach pain is manageable at home. But there are clear signals that mean you should not wait:
- Pain that has persisted for more than 48 hours without improvement
- Severe pain in lower right side of the stomach (possible appendicitis)
- Pain accompanied by blood in stool, vomit, or urine
- Unexplained weight loss alongside recurring pain
- High fever with abdominal pain
- Pain during pregnancy that is persistent or severe
Frequently Asked Questions
Pain in the right side of the stomach can be caused by many conditions, including gas, appendicitis, gallstones, kidney issues, liver disease, or muscle strain. The location, severity, and associated symptoms help determine the cause. If pain is severe or persistent, consult a doctor.
No – while appendicitis causes pain in the lower right abdomen, it is not the only cause. Reasons for lower stomach pain in that region also include IBS, kidney problems, ovarian cysts (in women), and trapped gas. However, any sharp or worsening lower right pain should be evaluated promptly.
Antacids and simethicone tablets are generally safe for occasional use for mild gas or acidity. However, relying on a stomach pain medicine regularly without a diagnosis is not advisable. A gastroenterologist can help identify the root cause and recommend appropriate treatment.
Not always. Mild stomach pain in pregnancy due to gas, round ligament pain, or Braxton Hicks contractions is common. However, severe or persistent pain, especially with fever, bleeding, or unusual discharge, requires immediate medical attention.
For stomach pain gas, try gentle walking to help move gas through the digestive tract, warm ginger tea, avoiding carbonated drinks, and eating slowly. Over-the-counter simethicone drops or tablets can also provide quick relief.
Conclusion: Don’t Ignore What Your Body Is Telling You
Pain in the right side of the stomach can range from a harmless gas bubble to a condition that needs prompt medical care. Understanding the stomach pain reasons that apply to your situation – whether it’s upper stomach pain after eating, discomfort during pregnancy, or persistent lower right pain – is the first step toward the right treatment.
A stomach pain tablet can offer temporary stomach pain relief, but it’s not a substitute for an accurate diagnosis. If your symptoms are recurring, worsening, or accompanied by other warning signs, it’s always best to consult a qualified medical professional.
