diarrhea imaging results waiting

Overview

Diarrhea is when you have loose, watery bowel movements more often than usual. Sometimes, to find out why it's happening, your doctor may order imaging tests like a CT scan or ultrasound to look inside your belly. Waiting for those results can feel long and worrying, but knowing what to expect can help you stay calm and prepared.

Yes, diarrhea is very common. Most people have it at some point in their lives.

Anyone can get diarrhea, but it is more common in young children, older adults, and people with weak immune systems or those traveling to areas with poor sanitation.

Symptoms

Common symptoms

• Loose, watery stools
• Frequent bowel movements
• Urgent need to go to the toilet
• Cramping or pain in the belly
• Bloating or nausea

Symptoms in children

• Same as adults, plus signs like not wanting to eat, crying without tears, sunken eyes, or dry mouth and diaper
• Fever
• Fussiness or unusual sleepiness

Symptoms in older adults

• More risk of dehydration, which can cause confusion, weakness, and dizziness
• Longer lasting diarrhea
• Sometimes only mild stomach pain

Causes

Main causes

• Infections – viruses (like norovirus), bacteria (like E. coli), or parasites
• Food intolerance – trouble digesting lactose or gluten
• Medications – antibiotics or some heart medicines can cause diarrhea
• Digestive disorders – like irritable bowel syndrome (IBS) or inflammatory bowel disease (IBD)
• Travel – contaminated food or water in some regions

Risk factors

• Recent travel to areas with poor water or food safety
• Recent antibiotic use
• Having a weakened immune system (from illness or treatments)
• Living in or visiting a community with a diarrheal outbreak
• Age – very young or very old

When to see a doctor

See a doctor urgently if:

• If you have signs of severe dehydration (no urine, dizziness, confusion)
• If you see blood in your stool
• If you have a high fever that won't go down
• If the pain is very bad or constant

Book a routine appointment if:

• If diarrhea lasts more than 2 days (adults) or more than 1 day (children)
• If you are losing weight without trying
• If you are worried about the cause and want to talk it through

Diagnosis

Your doctor will ask about your symptoms, check your belly, and may order tests to find the cause. Imaging tests like a CT scan or ultrasound create pictures of the inside of your body to look for problems.

Tests that may be done

• Stool test – to check for infection or blood
• Blood test – to check for signs of infection or dehydration
• CT scan – a detailed X-ray that shows your intestines and other organs
• Ultrasound – uses sound waves to see the belly
• Sometimes an X-ray or MRI

What to expect at your appointment

For a CT scan, you may be asked to drink a contrast liquid and lie still on a table. The test is painless and takes about 10–30 minutes. Results usually come back in a few days. Your doctor will call or schedule a visit to go over them with you.

Treatment

Treatment depends on what the imaging and other tests show. Often diarrhea just needs time to clear up. If a cause is found, your doctor will recommend the right approach.

Self-care at home

• Drink plenty of clear fluids like water, clear broths, or oral rehydration solutions
• Eat bland foods like bananas, rice, applesauce, and toast (the BRAT diet)
• Avoid dairy, fatty foods, caffeine, and alcohol until you're better
• Wash your hands often to avoid spreading infection
• Rest as much as possible

Medical treatments

If tests show a bacterial infection, your doctor may prescribe antibiotics. For other causes, they might recommend medications to help slow down the diarrhea or protect your gut. Always follow your doctor’s advice – never take over-the-counter diarrhea medicines without checking first, as they can make some infections worse.

When is surgery considered?

Surgery is very rarely needed for diarrhea. It might be considered if imaging finds a serious problem like a blocked intestine or a mass. Your doctor will discuss this with you if it applies.

Living with this condition

While you wait for results, focus on staying hydrated and comfortable. Keep a note of how often you go to the toilet and any other symptoms. This will help your doctor when you talk about the results.

Lifestyle tips

• Take it easy – your body needs rest to heal
• Avoid heavy physical activity until you feel better
• Stay near a toilet if you have urgency
• Consider keeping a simple food diary to see if certain foods make things worse

Diet and exercise

Stick to light, easy-to-digest foods. Gentle movement like a short walk is fine, but don't push yourself. Once you are better, you can slowly return to your normal diet and activities.

Mental health and emotional wellbeing

Waiting for results can be stressful. You may feel anxious or worried about what the images will show. It’s normal to have these feelings. Talk to a trusted friend or family member, and let your healthcare team know if you're struggling – they can offer support or refer you to a counselor.

Prevention

You can lower your chance of getting diarrhea by washing your hands well, especially after using the toilet and before eating. When traveling, drink bottled water and avoid raw or undercooked foods. If you take antibiotics, talk to your doctor about ways to protect your gut.

Vaccines

There are vaccines for some causes of diarrhea, like rotavirus in children and cholera for travelers. Ask your healthcare provider if any vaccines are right for you or your family.

Screening programmes

Routine screening for diarrhea is not needed. If you have frequent or long-lasting symptoms, your doctor may recommend tests to check for underlying conditions.

Complications

If left untreated

• Dehydration – when your body doesn't have enough water
• Electrolyte imbalance – loss of important minerals like sodium and potassium
• Malnutrition – if diarrhea lasts a long time, your body may not absorb enough nutrients
• In rare cases, infection can spread to other parts of the body

Long-term outlook

Most people recover fully from diarrhea, especially with proper rest and fluids. Imaging results will give your doctor a clearer picture, and together you can address any issues found. With the right care, the outlook is very good.
