Nausea, Heartburn, Indigestion, Upset Stomach and Diarrhea

Short answer
Nausea with heartburn, indigestion, an upset stomach, or diarrhoea can have several causes, so symptoms and warning signs guide the next step.
This answers one question. It is not a diagnosis and does not replace an assessment by a licensed doctor.
At a glance
- Symptoms may overlap
- Burning, nausea, upper-abdominal discomfort, and loose stools can occur together
- Track
- Timing, meals, medicines, pain, vomiting, and stool changes
- Urgent warning
- Blood, severe pain, chest symptoms, fainting, or dehydration
How these symptoms fit together
Heartburn is a burning feeling behind the breastbone, while indigestion can cause upper-abdominal discomfort, early fullness, belching, or nausea. Diarrhoea points to faster movement through the bowel and may occur with an infection, food intolerance, or another digestive problem. Symptoms can overlap without having one single cause.
Acid reflux, gastritis, a hiatus hernia, peptic ulcer, or Helicobacter pylori infection can contribute to upper-digestive symptoms. Gallstones may cause pain after eating, particularly in the upper right abdomen. A symptom combination alone cannot identify the cause.
What you can do now
Sip fluids regularly, especially after loose stools, and choose simple foods in small portions if eating feels difficult. Avoid alcohol and foods that clearly trigger burning or diarrhoea. Remain upright after meals and keep a note of timing, foods, stool changes, pain, vomiting, and medicines.
A pharmacist can explain whether an antacid, acid-reducing option, or rehydration product is suitable. Use medicines only as directed, and ask before taking anti-diarrhoea or acid-reducing treatment if you have blood in the stool, fever, severe pain, pregnancy, or other medical conditions.
Warning signs that need assessment
Seek urgent care for severe or worsening abdominal pain, chest pain, trouble breathing, vomiting blood, black stools, blood in the stool, fainting, confusion, or signs of dehydration. Arrange a medical review if symptoms keep returning, swallowing becomes difficult, vomiting persists, or diarrhoea does not settle.
Questions for your doctor
Ask whether your pattern fits reflux, indigestion, infection, or another condition, and whether testing is needed. Bring a list of medicines and describe any weight change, nighttime symptoms, food triggers, stool changes, and family history of digestive disease.

Questions people ask
Can reflux cause nausea?
Yes. Reflux can irritate the upper digestive tract and may occur with nausea or a sour taste, although other causes are also possible.
Should diarrhoea with heartburn be checked?
Seek care promptly for blood, severe pain, dehydration, persistent vomiting, or symptoms that keep returning. Otherwise, fluids and a clinical review can help if it does not settle.
