Understanding Stomach Pain: Common Causes

People of all ages experience stomach aches for various reasons.
However, if one continues to have mild to severe pain in their stomach, it could be a sign of a serious health condition that demands medical attention.
Stomach pain could be caused by various reasons:
- Indigestion: Caused by overeating, consuming spicy or fatty foods, or excessive caffeine and alcohol intake.
- Gastroesophageal Reflux Disease (GERD): GERD is a chronic condition wherein stomach acid frequently flows back into the oesophagus, causing heartburn.
- Stomach Ulcers: Open sores that develop on the stomach lining due to infection or prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs).
- Irritable Bowel Syndrome (IBS): A disorder affecting bowel function, causing bloating, cramping, and irregular bowel movements.
- Food Intolerances and Allergies: Reactions to certain foods, such as dairy or gluten, leading to digestive issues.
- Gallstones: Hardened deposits in the gallbladder that can cause severe pain and digestive distress.
- Cancer: Cancers growing in the abdominal region can cause stomach pain, which is often persistent and gets worse with time.
Key Signs That You Should Visit a Gastroenterologist
While mild stomach pain often resolves on its own, certain symptoms require professional evaluation. Here are key signs that you should see a GI specialist for a proper evaluation.
- Persistent or Severe Stomach Pain
If you experience severe stomach pain that lasts more than a few days or worsens over time, it could be a sign of a serious condition such as appendicitis, ulcers, or gallbladder disease. Failure to attend to this pain could result in complications that need urgent medical attention.
- Unexplained Weight Loss
Losing weight without changes in diet or exercise can indicate digestive disorders like Crohn’s disease, coeliac disease, or even stomach cancer. It is essential to get screened early to rule out any serious health concerns.
- Chronic Heartburn or Acid Reflux
Frequent acid reflux or heartburn that doesn’t improve with over-the-counter medications may indicate the presence of GERD. GERD needs medical treatment to avoid problems such as erosive oesophagitis and Barrett’s syndrome.
- Difficulty Swallowing
When you have trouble swallowing food and drinks or feel pain, it might be because of disorders such as esophageal stricture, GERD, or even esophageal cancer. Additionally, choking as well as a lack of nutrients can occur if one finds it hard to swallow.
- Blood in Stool or black stool
Visible blood in stool or black, tarry stools may indicate gastrointestinal bleeding, ulcers, or inflammatory bowel disease (IBD). Seeking immediate medical attention can prevent further complications.
- Persistent Bloating and Gas
Excessive bloating, gas, and discomfort that persist for weeks could be signs of conditions such as IBS, lactose intolerance, small intestinal bacterial overgrowth (SIBO), or even ovarian cancer in women. Consulting a gastroenterologist can help identify the cause.
- Chronic Diarrhoea or Constipation
Frequent diarrhoea or constipation lasting more than a few weeks may indicate IBS, infections, or more severe digestive issues requiring gastroenterology treatment. Persistent changes in bowel habits should not be ignored.
- Vomiting or Nausea That Won’t Go Away
Recurring nausea and vomiting could be a sign of gallbladder disease, stomach ulcers, gastrointestinal obstruction, or even liver disease. Seeking professional evaluation can help determine the cause and proper treatment.
- Family History of Digestive Disorders
If you have a family history of conditions like Crohn’s disease, ulcerative colitis, or colon cancer, regular checkups with a gastroenterologist are crucial for early detection and preventive care.
