Common digestive causes of stomach pain
Indigestion (Dyspepsia)
Overeating, eating spicy foods, or drinking too much caffeine or alcohol can trigger indigestion, leading to bloating, discomfort, and a burning sensation in the stomach.
Gastroesophageal Reflux Disease (GORD)
GORD occurs when stomach acid flows back into the oesophagus, irritating. It often results in a burning pain in the upper stomach and chest, commonly known as heartburn.
Gas and Bloating
Trapped gas in the intestines can lead to cramping and pressure-related discomfort. It may be caused by swallowing air, eating certain foods, or an imbalance in gut bacteria.
Constipation
Infrequent bowel movements and hard stools can cause bloating and pain in the abdomen. This may result from dietary choices, dehydration, or living a sedentary lifestyle.

Stomach infections and inflammation
Gastroenteritis (stomach flu)
Viral or bacterial infections can inflame the stomach lining, leading to nausea, vomiting, diarrhoea, and cramping. These symptoms often resolve on their own but can sometimes require medical attention.
Helicobacter pylori (H. pylori) Infection
H.pylori is a bacterial infection that can cause chronic stomach pain and is linked to stomach ulcers. Many individuals do not experience symptoms, but in some cases, it leads to ongoing digestive discomfort.
Food poisoning
Consuming contaminated food can potentially result in severe stomach pain, nausea, vomiting, and diarrhoea. In most cases, symptoms typically develop within hours of ingestion and can last for several days.
Gastritis
Inflammation of the stomach lining may be caused by infections, prolonged stress, or certain medications. Gastritis can result in persistent pain, nausea, dizziness, and a burning sensation in the stomach.

More serious medical conditions
Stomach Ulcers
These open sores in the stomach lining often cause burning pain. They may develop due to H. pylori infection or prolonged use of certain medications.
Gallstones
These hardened deposits in the gallbladder can block bile flow, leading to sharp pain in the upper abdomen, particularly after eating fatty foods.
Appendicitis
This condition begins with dull pain around the belly button, which gradually shifts to the lower right abdomen. It requires urgent medical attention.
Hernias
A hernia occurs when an organ pushes through the abdominal wall, leading to discomfort, particularly when lifting heavy objects or straining too much.

Food-related triggers
Lactose intolerance
Difficulty digesting lactose, a type of sugar found in dairy products, can result in bloating, diarrhoea, and stomach cramps.
Gluten sensitivity or coeliac disease
Consuming gluten can cause digestive discomfort and inflammation in individuals with gluten sensitivity or Coeliac disease.
Spicy and fatty foods
These foods may irritate the stomach lining, leading to discomfort, especially in individuals with pre-existing digestive issues.
Food allergies
Certain kinds of foods can trigger an immune response in some people, resulting in stomach pain, nausea, and other symptoms.
