Stomach Pain and Nausea: Causes and When to See a Doctor
Stomach pain with nausea can result from indigestion, gastritis, or conditions such as appendicitis and gallstones. Learn about its causes, treatments, home remedies, and warning signs that require medical attention.
Quick Answer:
Stomach pain and nausea can result from common issues such as indigestion, gastritis, gastroenteritis, or food poisoning, or from more serious issues including appendicitis, kidney stones, or peptic ulcers.
Seek urgent medical care if the pain is sudden or severe, or comes with vomiting blood, blood in the stools, chest pain, difficulty breathing, or fainting. Mild symptoms often ease with small sips of fluid and small bland meals. See a doctor if they keep returning, or if there is repeated vomiting or signs of dehydration.
What Causes Stomach Pain With Nausea?
Stomach pain with nausea can occur due to digestive problems, infections, food-related reactions, medications, or underlying medical conditions.
When abdominal discomfort and nausea occur at the same time, it generally means that your digestive system is irritated, inflamed, or reacting to a trigger.
Indigestion
Dyspepsia, also called indigestion, can cause abdominal discomfort, bloating, a feeling of fullness in the abdomen, burping, and nausea, particularly after eating.
Gastroenteritis
Gastroenteritis refers to inflammation of the stomach and intestines caused by viruses, bacteria, or parasites. It can lead to stomach pain and nausea, along with vomiting and diarrhoea.
Food Poisoning
Consumption of contaminated food or drinks can cause sudden stomach pain, nausea, vomiting, diarrhoea, and fever.
Food Intolerance
Difficulty digesting certain foods, such as lactose, can cause abdominal discomfort, bloating, gas, and nausea.
Acid Reflux
Stomach acid flowing back into the oesophagus can cause upper abdominal discomfort, nausea, heartburn, or regurgitation.
Functional Dyspepsia
When recurring upper abdominal symptoms have no identifiable cause after medical checks, it may be called functional dyspepsia. It can cause recurring upper abdominal pain or discomfort, nausea, bloating, and feeling full sooner than expected.
Gastritis
Inflammation of the stomach lining can cause upper abdominal pain, nausea, vomiting, and loss of appetite. Gastritis may occur because of H. pylori bacteria, alcohol consumption, or certain medicines such as ibuprofen.
Peptic Ulcers
Peptic ulcers are sores in the stomach or upper small intestine. They may cause burning or aching abdominal pain along with nausea and bloating.
Gallstones
Gallstones are hardened deposits of bile fluid in the gallbladder. They can cause abdominal pain and nausea, particularly after a heavy meal.
Pancreatitis
Inflammation of the pancreas can cause severe upper abdominal pain, often with nausea and vomiting.
Medication-Related Stomach Irritation
Medicines such as nonsteroidal anti-inflammatory drugs (NSAIDs) can irritate the stomach lining and may contribute to gastritis or ulcers, which can then cause stomach pain and nausea.
Some antibiotics, iron tablets, and other medicines can also cause nausea even without directly irritating the stomach lining.
Kidney Stones
When kidney stones move through or become stuck in the urinary tract, they can cause severe pain in the abdomen or lower back along with nausea, vomiting, and blood in the urine. The pain may come in waves and can shift as the stone moves.
Pregnancy
In its early stages, pregnancy can sometimes cause stomach discomfort and nausea.
Menstruation
Hormonal changes during the menstrual cycle can cause abdominal cramps, nausea, and digestive symptoms such as bloating or diarrhoea. These symptoms often occur around the start of a period and may improve as menstruation progresses.
Irritable Bowel Syndrome (IBS)
IBS can cause stomach pain along with bloating, nausea, and changes in bowel movements such as diarrhoea, constipation, or both.
Appendicitis
Appendicitis occurs when the appendix becomes inflamed. The pain may initially develop around the belly button and later move to the lower right side of the abdomen, often with nausea, vomiting, and loss of appetite.
Heart Attack
Although less common, a heart attack can sometimes cause discomfort in the upper abdomen along with nausea.
Bowel Obstruction
A bowel obstruction occurs when a blockage prevents food, fluids, and gas from moving normally through the intestines. It can cause abdominal pain, nausea, vomiting, bloating, and difficulty passing stool or gas.
Hepatitis
Inflammation of the liver can cause nausea and pain in the upper right part of the abdomen. Other symptoms may include fatigue, loss of appetite, dark urine, and yellowing of the skin or eyes.
Diabetic Ketoacidosis (DKA)
DKA is a serious complication of diabetes that can cause nausea, vomiting, and abdominal pain along with excessive thirst, frequent urination, weakness, and rapid or deep breathing.
Urinary Tract Infection (UTI)
A UTI can cause lower abdominal discomfort along with nausea, particularly if the infection spreads to the kidneys. Fever, chills, back or side pain, and painful or frequent urination may also occur.
Typhoid Fever
Typhoid is a bacterial infection that can cause prolonged fever along with abdominal pain, nausea, vomiting, diarrhoea, or constipation. Medical evaluation is important because untreated infection can lead to serious complications.
Dengue
Dengue can cause nausea and abdominal pain along with fever, headache, body aches, and other symptoms.
What Causes Stomach Pain With Nausea After Eating?
Stomach pain and nausea after eating may result from indigestion, food intolerance, food poisoning, functional dyspepsia, acid reflux, gastritis, stomach ulcers, or gallstones.
Eating too quickly, certain foods, or larger meals can also trigger symptoms in some people.
If these symptoms occur regularly after meals, speak with a doctor to identify the underlying cause rather than repeatedly avoiding foods without medical guidance.
How Can You Treat Stomach Pain and Nausea?
Treatment for stomach pain and nausea depends on the underlying cause. Mild symptoms may improve with hydration, dietary adjustments, or suitable medicines, while persistent symptoms may require medical evaluation and specific treatment.
Over-the-Counter Medicines for Stomach Pain and Nausea
For mild stomach pain and nausea, certain over-the-counter medicines may help relieve specific symptoms such as acidity, gas, or indigestion.
- Antacids: May provide temporary relief from acid-related indigestion or heartburn.
- Simethicone: May help relieve discomfort associated with trapped gas and bloating.
Home Remedies for Stomach Pain and Nausea
For mild symptoms, a few simple measures may help you feel more comfortable while your digestive system recovers.
- Sip fluids frequently: Take small, regular sips of water. If vomiting or diarrhoea causes fluid loss, an oral rehydration solution may help replace fluids and electrolytes.
- Eat small portions: Try smaller meals and eat slowly. Bland foods may be easier to tolerate while nausea persists.
- Eat ginger or drink warm ginger tea: Ginger may help ease nausea in some people, although evidence for relieving stomach pain itself is weaker.
- Drink warm peppermint tea: Peppermint may help some digestive discomfort, but it can worsen acid reflux or heartburn in some people.
- Avoid trigger foods: Temporarily limit oily or spicy foods, alcohol, and caffeine if they worsen your symptoms.
When Should You Consult a Doctor for Stomach Pain and Nausea?
Seek immediate medical attention if stomach pain is sudden or severe, or if it occurs with:
- Blood in your vomit or stool
- Black or tarry stools
- Yellowing of the skin or eyes
- Chest pain
- Difficulty breathing
- Fainting
You should also seek prompt medical care if you experience:
- Repeated vomiting or inability to keep fluids down
- Signs of dehydration such as very little urine, dark urine, or persistent dizziness
- Worsening abdominal pain
- High fever
- A hard or rigid abdomen
Arrange a doctor's appointment if nausea and stomach pain keep returning, interfere with eating, or persist without improvement. Unexplained weight loss also warrants evaluation.
