Overview
Stomach cramps and diarrhoea are common digestive complaints experienced by many Australians. They often occur together and are usually caused by gut infections (commonly known as “gastro”), food-related triggers, or even stress. In most cases, symptoms are mild and resolve within a few days. However, if symptoms are severe, last longer than expected, or accompanied by warning signs, it’s important to seek medical assistance from a doctor.Why do stomach cramps and diarrhoea happen?
These symptoms happen when the digestive tract becomes inflamed or irritated and disrupts digestion. This can be caused by an infection, food intolerance, or other triggers, leading to stomach cramps, diarrhoea, or a strong urge to go to the toilet.What causes stomach cramps and diarrhoea?
There are several possible causes. Common causes include:- Food poisoning from contaminated food or water
- Food intolerance or sensitivities
- Viral infections, such as gastroenteritis
- Stress or anxiety
- Irritable Bowel Syndrome (IBS)
- Certain medications
- Inflammatory bowel conditions, such as Crohn’s Disease or Ulcerative Colitis
- Travel-related illness called traveller’s diarrhoea
Common symptoms that may occur together
Alongside loose stools, you may also experience:- Abdominal cramps or pain
- Nausea or vomiting
- Fever or chills
- Loss of appetite
- Bloating
- Urgency to go to the toilet
- Fatigue
How long does it usually last?
For most people, symptoms caused by a viral infection improve within 1-3 days, though diarrhoea can sometimes persist for up to 10 days. Vomiting usually resolves sooner, within one or two days. If your symptoms last longer, get worse, or if you develop new or concerning symptoms, it’s a good idea to speak with a doctor. Symptoms continuing beyond two weeks may suggest an underlying condition that needs further investigation.What to do at home
Most mild cases can be easily managed at home. Helpful steps include:- Stay well hydrated
- Rest as much as possible
- Eat small, easy-to-digest meals when you feel ready
- Wash your hands thoroughly, especially before eating food
- Monitor your symptoms closely
Foods to avoid during diarrhoea
While recovering, it is best to stay away from foods and drinks that may trigger or worsen symptoms:- Spicy foods
- Greasy, fatty, or fried foods
- Dairy products (it may worsen symptoms)
- Caffeinated drinks (coffee, energy drinks)
- Sugary drinks or fruit juices
- High-fibre foods, such as raw vegetables, whole grains, or legumes
- Alcohol
When to see a doctor
While most cases of stomach cramps and diarrhoea are mild and short-lived, there are times when it’s important to see a doctor. See a doctor if you experience any of the following:- Diarrhoea lasting more than a few days
- High fever
- Blood or mucus in the stool
- Severe or worsening abdominal pain
- Signs of dehydration
- Trouble keeping fluids down
- Recurring symptoms
Signs of dehydration
Dehydration is one of the biggest risks of diarrhoea and vomiting. This can be serious, especially in babies, children, and older adults. Signs to watch for include:- Dry mouth and lips
- Increased thirst
- Headache or dizziness, especially when standing
- Rapid heartbeat
- Tiredness or confusion
- Dark coloured urine or urinating much less than usual

Stomach cramps and diarrhoea in children
Children, especially babies and toddlers, are more likely to become dehydrated because their bodies hold less fluid. If your child is experiencing diarrhoea or vomiting, give small amounts of fluid multiple times. Oral rehydration solutions are recommended for young children and older adults to help replace lost fluids and electrolytes. Babies under 6 months should always be assessed by a doctor if you suspect gastroenteritis. For older children, seek medical care promptly if they are unable to keep fluids down, appear unusually drowsy, show signs of dehydration, have blood in their stool, or their symptoms continue for more than 24 hours. Can telehealth help with stomach cramps and diarrhoea? Yes, for many people, telehealth can be a convenient option for getting medical advice from home. A doctor can assess your symptoms, offer advice, recommend next steps, and, if clinically appropriate, provide prescriptions, referrals, or medical certificates. However, telehealth has some limitations. A doctor cannot physically examine you during an online consultation, and some health concerns may need a face-to-face appointment. Telehealth generally works best for mild to moderate symptoms and should be viewed as a complementary option rather than a replacement for in-person care. If your symptoms are severe, you are struggling to stay hydrated, or if you feel extremely unwell, please attend a medical clinic, hospital, or call 000.Telehealth vs in-person consultation
Here is a table to help guide your decision:| Aspect | Telehealth consultations | In-person consultation |
| Suitable for | Mild to moderate symptoms, follow-up, advice, prescriptions (if clinically appropriate) | Severe symptoms, suspected complications, or physical examination is required |
| Accessibility | From home, no travel required | Requires attending a clinic or hospital |
| Wait time | Often, within a few minutes | Variable, may involve waiting at a clinic or ED |
| Physical examination | Not possible | Full examination possible |
| Prescriptions | May be issued if clinically appropriate and at the practitioner's discretion | May be issued following a physical assessment |
| Pathology, Referrals | Can be arranged remotely if clinically appropriate | Can be arranged following a physical assessment |
| Best for | Adults and children with mild gastro who can stay hydrated | Severe symptoms, signs of dehydration, blood in stool, or when telehealth is not sufficient. |
Possible treatments a doctor may recommend
A doctor’s advice will depend on the cause of your symptoms and their clinical assessment. Options include:- Oral rehydration therapy
- Antibiotics
- Dietary changes
- Stool or blood tests
- Referral to a specialist for further assessment if clinically appropriate
Prevention tips
Most cases of stomach cramps and diarrhoea can be resolved or prevented with simple hygiene and food safety habits:- Wash your hands thoroughly with soap and water
- Avoid eating raw or undercooked meat, poultry, and eggs
- Follow safe food handling practices (store, cook, and reheat food properly)
- Be careful with food and water when travelling
- Drink clean water
- Stay home when unwell and avoid preparing food for others
