colic screening test preparation
Informed by recognized medical guidance
Overview
Colic is when a healthy baby cries for more than 3 hours a day, more than 3 days a week, for more than 3 weeks. A colic screening test is not a single test but a series of checks a doctor may do to rule out other causes of crying. Preparation helps make these checks easier.
Key facts
- Colic usually starts when a baby is about 2 weeks old and ends by 4 to 6 months.
- There is no specific laboratory test for colic; doctors diagnose it based on symptoms and by ruling out other conditions.
- Preparing for a screening visit can involve keeping a diary of crying times, feeding, and diaper changes.
Yes, colic is very common. About 1 in 5 babies experience colic.
Colic affects babies, usually those who are otherwise healthy. It can happen to any baby, regardless of gender, feeding method, or family background.
Symptoms
- Baby is limp or difficult to wake
- Baby has a fever over 38°C (100.4°F) if under 3 months old
- Baby is vomiting green fluid or blood
- Baby has a swollen or tender tummy
- Baby is having trouble breathing
- Baby has blood in their stool
- ⚠Crying that is constant and getting worse
- ⚠Baby is not feeding or wetting diapers as usual
- ⚠You are worried about your baby's wellbeing
- ⚠You feel overwhelmed or are afraid you might hurt your baby
Common symptoms
- Crying that starts and stops for no clear reason
- Crying in the late afternoon or evening
- Baby may pull up their legs, arch their back, or clench their fists
Symptoms in children
- Colic typically only occurs in infants under 4 to 6 months old. Older children do not get colic.
Symptoms in older adults
- Colic does not affect older adults. If an older adult has severe abdominal pain, it may be a sign of another condition and needs medical attention.
Causes
Main causes
- The exact cause of colic is unknown. It may be due to an immature digestive system or a baby's sensitivity to stimulation.
- Some researchers think colic might be related to gas, acid reflux, or a temporary imbalance of gut bacteria.
- It is not caused by something the parent did or did not do.
Risk factors
- Babies born before 37 weeks (preterm) may have a slightly higher risk.
- Maternal smoking during pregnancy or after birth increases the chance of colic.
- Having a family history of colic may also play a role.
When to see a doctor
See a doctor urgently if:
- If your baby shows any of the emergency signs listed above.
- If the crying is accompanied by a fever, vomiting, or a rash.
- If your baby is not gaining weight or seems to be in pain.
Book a routine appointment if:
- Schedule a visit if the crying patterns last longer than 3 weeks.
- See your doctor to talk about ways to soothe your baby and check for other conditions.
- If you are feeling stressed or exhausted, a doctor or nurse can offer support.
Diagnosis
A doctor will diagnose colic by listening to your description of your baby's crying and doing a physical exam. They may ask you to keep a diary of crying, feeding, and sleeping. The diagnosis is made after ruling out other medical issues.
Tests that may be done
- No specific test can diagnose colic, but your doctor might recommend a urine test to check for infection.
- A stool test may be done to look for blood or signs of infection.
- In rare cases, an ultrasound or other imaging test may be used to check for problems in the belly.
What to expect at your appointment
Preparation for these tests is usually simple. For a urine test, you may be asked to collect a sample using a special bag. For a stool test, you will collect a small amount of stool from the diaper. For an ultrasound, your baby may need to have a full tummy (not feed right before) or an empty tummy depending on the test. Your doctor will give you specific instructions. The tests are quick and help rule out other worries.
Treatment
There is no cure for colic, but it goes away on its own. Treatment focuses on comforting your baby and helping parents cope. Many strategies can help soothe a colicky baby, and different things work for different babies.
Self-care at home
- Try gentle rocking, swaddling, or using white noise.
- Offer a pacifier or a gentle tummy massage.
- Hold your baby upright after feeds to help with gas.
- Take breaks and ask for help when you need it.
Medical treatments
Doctors may sometimes suggest over-the-counter remedies like simethicone drops or probiotics, but these do not work for every baby and should only be used after consulting a healthcare provider. Prescription medicines are rarely used for colic. Always talk to your doctor before giving any medicine to your baby.
When is surgery considered?
Surgery is not needed for colic. If an underlying condition like a hernia or blockage is found, surgery may be needed, but that is not part of colic treatment.
Living with this condition
Living with a colicky baby can be challenging. The crying can be stressful, but remember it is temporary. Try to keep a routine, share care with a partner or family member, and take care of your own health.
Lifestyle tips
- Accept help from friends and family so you can rest.
- Limit visitors if your baby seems overstimulated.
- Try using a baby carrier or going for a walk to soothe your baby.
Diet and exercise
If you are breastfeeding, some mothers find that avoiding caffeine, dairy, or spicy foods may help. But there is no strong evidence that diet changes always work. Talk to your doctor before changing your diet. Exercise for yourself can help reduce stress—even a short walk can make a difference.
Mental health and emotional wellbeing
Caring for a colicky baby can be exhausting and may lead to feelings of frustration or guilt. It is normal to feel this way. If you feel overwhelmed, angry, or depressed, please reach out to a healthcare provider or a mental health professional. You are not alone.
Prevention
There is no proven way to prevent colic. However, avoiding smoking during pregnancy and after birth may lower the risk. Breastfeeding and responsive feeding (feeding when the baby shows hunger cues) may also help reduce crying in some babies.
Vaccines
Vaccines do not prevent colic. Keep your baby up to date on routine vaccines to protect against other illnesses.
Screening programmes
There is no screening test to predict which babies will get colic. Regular well-baby checkups help ensure your baby is growing and developing well.
Complications
If left untreated
- Colic itself does not cause harm to the baby. However, the stress of caring for a colicky baby can affect parental mental health.
- If a parent becomes overwhelmed, they may have difficulty bonding with the baby or may feel depressed.
Long-term outlook
The outlook for colic is excellent. Almost all babies outgrow it by 4 to 6 months with no lasting effects. With support and patience, this difficult period will pass, and your baby will become a happy, healthy child.
