CLAIM:
The viral reel claims that persistent, especially green-coloured, vomiting in infants is not normal and may indicate intussusception, a condition in which one part of the intestine telescopes into another and causes a blockage. It suggests that repeated green vomiting is a medical emergency that requires immediate attention to prevent serious complications.
FACT:
Persistent or recurrent vomiting in children, especially green or bile-stained vomiting, is not normal and can be a warning sign of intussusception or other forms of intestinal obstruction. Studies and expert opinion indicate that early diagnosis and treatment are crucial, as delayed care can lead to bowel damage and other serious complications. Experts advise parents to seek immediate medical attention if a child has repeated episodes of vomiting, particularly if accompanied by abdominal pain, excessive crying, lethargy, poor feeding, abdominal swelling, or blood in the stool.
In a viral Instagram reel posted by Dr Imran Patel, a paediatrician, the doctor highlights how persistent green-coloured vomiting in infants can be a warning sign of a serious condition called intussusception and should not be ignored.
In the reel, Dr Patel shares the case of a four-month-old girl from a village about 450 km away from Ahmedabad, who had been experiencing repeated episodes of green-coloured vomiting for five days. Speaking directly to viewers, he says, “You can see that her stomach is swollen. And this girl had a complaint that she has been vomiting continuously for 5 days. That too green coloured vomiting. This is a red signal.”
Dr Patel explains that investigations revealed the baby had intussusception, a condition in which one part of the intestine slides into another, causing an obstruction. “A part of one intestine had entered the other intestine. Because of which blockage was happening,” he says. According to him, the delay in seeking treatment had led to damage to a portion of the intestine, requiring emergency surgery and removal of the affected section.
After spending eight days in the hospital and intensive care unit following a three-hour surgery, the child recovered and resumed breastfeeding. Addressing parents, Dr Patel says, “Vomiting green colour again and again. This is a red sign. You have to take action immediately.”
Can persistent vomiting in children indicate intussusception?
Persistent vomiting, particularly green or bilious vomiting, can be a warning sign of intussusception, a potentially serious condition in which one part of the intestine telescopes into an adjacent segment, leading to bowel obstruction and compromised blood supply if not treated promptly.
An earlier review study described intussusception as "the invagination of one portion of the bowel into an immediately adjacent portion" and noted that the condition differs considerably between children and adults. In children, most cases are idiopathic and commonly involve ileocolic intussusception. The authors emphasised that diagnosis in paediatric patients is usually made at clinical presentation and that standard treatment typically involves non-operative reduction using air or contrast enemas.
Evidence also suggests that prompt treatment can help avoid surgery. A 2012 retrospective study involving 135 children with intussusception found that primary enema reduction was successful in 61.5 per cent of cases. Among selected patients whose initial enema reduction failed, delayed repeat enemas successfully reduced many persistent intussusceptions, allowing several children to avoid unnecessary surgical procedures. The authors concluded that "the use of DRE in select patients with persistence of an intussusception may result in successful subsequent reduction with no apparent increase in morbidity."
Data from India further show that vomiting is one of the most common symptoms associated with the condition. A 2020 study conducted across 19 sentinel hospitals documented 1,588 cases of intussusception in children aged 2-23 months. Researchers found that vomiting was present in 63.4 per cent of cases, followed by bloody stools (49.1 per cent), abdominal pain (46.9 per cent), and excessive crying (42.8 per cent). However, the classical triad of vomiting, abdominal pain and blood in stools was seen in only about one-quarter of patients. Most cases were diagnosed by ultrasound, and mortality was low, with only 1 per cent of patients dying.
More recent research has highlighted the importance of early diagnosis in preventing severe complications. Another 2025 study focusing on infants aged three months or younger found that clinical manifestations were often atypical. Among 38 infants studied, vomiting was the most frequently reported symptom, occurring in 36 cases, followed by bloody stools and intermittent crying. Ultrasonography confirmed the diagnosis in 97.4 per cent of cases. The researchers concluded that "early USG should be performed to make a clear diagnosis, and the effect of early intervention is satisfactory."
Similarly, a 2025 review in emergency medicine described intussusception as one of the most common pediatric abdominal emergencies. According to the authors, untreated cases may progress to "obstruction, ischemia, necrosis, and perforation." While the classic triad of abdominal pain, currant jelly stool, and a sausage-shaped abdominal mass is uncommon, non-bilious vomiting and bloody stools are frequent manifestations. The review also noted that younger children may present atypically with lethargy or altered mental status, emphasising that clinicians should maintain a high index of suspicion. Ultrasound remains the diagnostic modality of choice, while stable patients without signs of perforation are generally managed with non-operative reduction.
Expert insights
According to Prof (Dr) N. Karthik Nagesh, Program Director – Pediatric Centres of Excellence at Aster CMI Hospital, Bengaluru, persistent or recurrent vomiting in infants and young children should not be dismissed as normal, particularly when it is accompanied by symptoms such as poor feeding, lethargy, dehydration, abdominal distension, or weight loss.
He stressed that green or bilious vomiting is especially concerning because it may indicate an intestinal obstruction requiring urgent medical attention. "One possible cause is intussusception, where a part of the intestine slides into another section and blocks the bowel," he said. However, he noted that other conditions, including intestinal malrotation with volvulus, bowel atresia, hernias, severe infections, and certain metabolic disorders, can also lead to green vomiting. "Since green vomiting can signal a serious underlying condition, parents should not wait for symptoms to improve on their own," he added.
Dr Karthik explained that green-coloured vomiting can occur in intussusception, particularly when the obstruction becomes more severe. Apart from vomiting, children may experience sudden episodes of severe abdominal pain, excessive crying, abdominal swelling, and lethargy. Some may draw their knees up to the chest during painful episodes or pass stools mixed with blood and mucus, often described as "red currant jelly" stools. He pointed out that symptoms can sometimes be atypical, presenting as unusual sleepiness, poor feeding, irritability, or weakness without obvious abdominal pain, which can make the condition difficult to recognise.
Describing intussusception as a medical emergency, Dr Karthik said delayed treatment can have serious consequences. "When one part of the intestine telescopes into another, it can block the passage of food and reduce blood flow to the affected bowel. If not treated promptly, the bowel tissue may become damaged, lose its blood supply and eventually die," he said. This may lead to bowel perforation, severe infection, shock and other life-threatening complications, sometimes necessitating surgery to remove the damaged segment of intestine. He emphasised that early diagnosis and treatment significantly improve outcomes and can often correct the condition without major surgery.
Dr Karthik advised parents to seek immediate medical care if a child experiences repeated episodes of vomiting, particularly if the vomit is green or bile-stained. "Parents should not wait for the symptoms to resolve on their own," he said. He urged caregivers to watch for accompanying signs such as severe abdominal pain, excessive crying, abdominal swelling, lethargy, poor feeding, dehydration, or blood in the stool. Prompt evaluation, he noted, helps identify the cause early, prevents complications, and improves the chances of successful treatment and recovery.
